Abstract

Family business owners and researchers tend to overwhelmingly focus on the top-level structure of firms but ignore the middle-level practice – involving family members in the middle-management team. Compared to top managers at the strategic apex, middle-level managers are mainly responsible for internal operations and control, and the composition of the middle-management team has an immediate and direct impact on the overall workforce efficiency of family firms. Integrating agency theory and organizational justice perspective, we proposed that family involvement in middle management would have a negative impact on the labor productivity of family firms. We further corroborated this effect by identifying three boundary conditions at the individual (i.e., familial CEO), organizational (i.e., firm size), and regional (i.e., labor mobility) levels. Using a sample of 1,284 privately owned family firms in China, we found that family involvement in middle management, measured as the percentage of familial middle-level managers, was negatively associated with labor productivity. Furthermore, this negative relationship existed only when the CEO is a family member rather than a professional manager, when the size of the firm is large rather than small, or when the firm is located in regions with low rather than high labor mobility. These findings contribute to family business literature and provide practical implications for human resource management in family firms.

摘要:

家族企业的所有者和研究者们通常更关注公司的高层结构, 却往往忽略了企业中层的一种重要实践——家族成员参与中层管理团队。相比位于战略顶层的高层管理者, 中层管理者主要负责内部运营和控制, 同时中层管理团队的构成会对家族企业的整体劳动力效率产生即刻的、直接的作用。通过整合代理理论和组织公平视角, 我们提出, 中层管理中的家族涉入会对家族企业的劳动生产率产生负面效果。我们进一步识别了个体层次 (家族CEO) 、企业层次 (企业规模) 和地区层次 (劳动力流动性) 的三个边界条件来证实这一效应。通过对中国1,284家私营家族企业的分析, 我们发现, 中层管理中的家族涉入 (中层管理团队中家族成员的比例) 与劳动生产率负相关。此外, 这一负向关系只存在于当CEO是家族成员而非职业经理人的时候, 当企业规模大而非小的时候, 或者当企业所在地区的劳动力流动性低而非高的时候。这些发现为家族企业研究领域做出了贡献, 并为家族企业中的人力资源管理提供了实践启示。

पारिवारिक व्यापार स्वामी व शोधक मूलतः उच्चतम स्तरीय फर्म संरचना पर केंद्रित होते हैं और मध्य-स्तरीय कार्यप्रणाली—जिसमें मध्य-स्तरीय प्रबंधन में परिवार के सदस्य शामिल होते हैं—को अनदेखा करते हैं. रणनैतिक शीर्ष स्तरीय उच्च प्रबंधकों की तुलना में मध्य-स्तरीय प्रबंधक मुख्यतः आंतरिक कार्यप्रणाली और नियंत्रण के लिए ज़िम्मेदार होते हैं और मध्य-स्तरीय प्रबंधक समूह के स्वरूप का तत्पर व सीधा प्रभाव पारिवारिक फर्म की समग्र निपुणता पर होता है. एजेंसी सिद्धांत व संगठनात्मक न्याय परिप्रेक्ष्य के संघटन के माध्यम से हमारा यह प्रस्ताव है की मध्य-स्तरीय प्रबंधन में परिवार के सदस्यों के योगदान का श्रम उत्पादकता पर नकारात्मक प्रभाव होगा. हमने इस प्रस्ताव को तीन स्तरीय परिसीमन स्थितियों—व्यक्तिगत (पारिवारिक मुख्य अधिशासी), संगठनात्मक (फर्म का आकार) और क्षेत्रीय (श्रम गतिशीलता) को निरूपित कर पुष्ट किया है. चीन की 1284 निजी स्वामित्व वाली पारिवारिक फर्मों के चयन से हमने यह पाया कि परिवार के मध्य-स्तरीय प्रबंधन में योगदान—जो मध्य-स्तरीय प्रबंधन में पारिवारिक सदस्यों के प्रतिशत से मापा गया है—श्रम उत्पादकता से ऋणात्मक तौर पर जुड़ा है. साथ ही यह भी पाया गया की यह ऋणात्मक जुड़ाव तभी है जब मुख्य अधिशासी व्यावसायिक न होकर उद्यमी परिवार का सदस्य है, जब संगठन का आकार वृहद् न होकर छोटा है, या जब फर्म तीव्र श्रम गतिशीलता क्षेत्र में न होकर निम्न श्रम गतिशीलता क्षेत्र में स्थित है. यह परिणाम पारिवारिक उद्यमों के शोध में योगदान करते हैं और ऐसी फर्मों में मानव संसाधन प्रबंधन के व्यावहारिक आशय पर प्रकाश डालते हैं.

SUMÁRIO:

Proprietários e pesquisadores de empresas familiares tendem a se concentrar predominantemente na estrutura de nível superior das empresas, mas ignoram a prática no nível médio – envolvendo um membro da família na equipe gerencial intermediária. Em comparação com gerentes de topo no ápice estratégico, os gerentes de nível médio são os principais responsáveis pelas operações internas e pelo controle, e a composição da equipe de gestão intermediária tem um impacto imediato e direto na eficiência geral da força de trabalho das empresas familiares. Integrando a teoria da agência e a perspectiva da justiça organizacional, propusemos que o envolvimento da família na gestão intermediária teria um impacto negativo na produtividade do trabalho das empresas familiares. Nós corroboramos ainda mais esse efeito identificando três condições de fronteira nos níveis individual (isto é, CEO da família), organizacional (isto é, tamanho da empresa) e regional (isto é, mobilidade de trabalho). Usando uma amostra de 1.284 empresas familiares privadas na China, descobrimos que o envolvimento da família na gestão intermediária, medido como a porcentagem de gerentes familiares de nível médio, estava negativamente associado à produtividade do trabalho. Além disso, essa relação negativa existia apenas quando o CEO é um membro da família e não um gerente profissional, quando o tamanho da empresa é grande em vez de pequeno, ou quando a empresa está localizada em regiões com baixa mobilidade de trabalho, ao invés de alta. Esses achados contribuem para a literatura sobre negócios familiares e fornecem implicações práticas para a gestão de recursos humanos em empresas familiares.

АННОТАЦИЯ:

АННОТАЦИЯ: Владельцы семейного бизнеса и исследователи, как правило, полностью сосредоточены на уровне управления высшего звена в компаниях и игнорируют практику среднего звена, т. е. участие члена семьи в команде среднего звена. По сравнению с управленцами высшего звена на стратегическом уровне, менеджеры среднего звена в основном отвечают за внутренние операции и контроль, а состав команды среднего звена оказывает непосредственное и прямое влияние на общую эффективность работы семейных фирм. На основании теории агентских отношений и перспективы организационной справедливости, мы предположили, что участие семьи в управлении среднего звена оказывает отрицательное влияние на производительность труда в семейных компаниях. Мы далее нашли подтверждение этому эффекту и определили три граничных условия на индивидуальном (т. е. член семьи на позиции генерального директора), организационном (т. е. размер фирмы) и региональном (т. е. мобильность рабочей силы) уровнях. Используя выборку из 1284 частных семейных компаний в Китае, мы обнаружили, что участие семьи в управлении среднего звена, которое измеряется как процент членов семьи работающих на уровне управления среднего звена, отрицательно влияет на производительность труда. Кроме того, эта отрицательная взаимосвязь существует только тогда, когда генеральный директор является членом семьи, а не профессиональным менеджером; когда размер фирмы большой, а не маленький; или когда фирма находится в регионах с низкой, а не с высокой мобильностью рабочей силы. Эти выводы вносят свой вклад в научную литературу по семейному бизнесу, а также дают практическое руководство для управления человеческими ресурсами в семейных фирмах.

RESUMEN:

Los dueños de las empresas familiares y los investigadores tienden a centrarse abrumadoramente en la estructura superior de las empresas pero ignoran la práctica del nivel medio –en relación a los miembros de la familia en el equipo de mandos medios. Comparado con los altos directivos en el ápice estratégico, los gerentes de nivel medio son principalmente responsables por las operaciones internas y el control, y la composición del equipo mandos medios tiene un impacto inmediato y directo sobre la eficiencia general de la fuerza laboral de las empresas familiares. Integrando la teoría de la agencia y la perspectiva de la justicia organizacional, proponemos que la participación de la familia en la gerencia media podría tener un impacto negativo en la productividad de las empresas familiares. Además corroboramos este efecto con la identificación de tres condiciones de contorno en los niveles: individual (es decir el CEO de la familia, organizacional (es decir, el tamaño de la empresa), y regional (es decir, movilidad laboral). Utilizando una muestra de 1.284 empresas familiares de propiedad privada en China, encontramos que la participación de la familia en los mandos medidos, medida como el porcentaje de gerentes de nivel medio de la familia, fue asociado negativamente con la productividad laboral. Adicionalmente, esta relación negativa existe solamente cuando el CEO es un miembro de la familia en lugar de un gerente profesional, cuando el tamaño de empresa es grande en lugar de pequeño, o cuando la empresa está ubicado en regiones con baja en lugar de alta movilidad laboral. Estos hallazgos contribuyen a la literatura de empresas familiares y proporcionan implicaciones prácticas para la gestión del recurso humano en empresas familiares.

INTRODUCTION

Family businesses play an active and pivotal role in global economic growth (Claessens, Djankov, Fan, & Lang, Reference Claessens, Djankov, Fan and Lang2002; Harris, Martinez, & Ward, Reference Harris, Martinez and Ward1994). In emerging economies, family businesses are particularly important because they show stronger dynamics and versatilities (Whyte, Reference Whyte1996), perform unique tasks such as wealth preservation (Carney, Reference Carney2007), and account for a higher proportion of national economic growth (Claessens, Djankov, & Lang, Reference Claessens, Djankov and Lang2000). For example, there are nearly eight million private enterprises in China, and more than eighty percent of those are family businesses (Steen & Baldwin, Reference Steen and Baldwin2015). One of the defining characteristics of family firms is a high level of family involvement, which reflects the family influence on the firms’ strategic decision making and daily operation management. Scholars have a fueling interest in family involvement because this striking nature of family business greatly affects firm outcomes (Anderson & Reeb, Reference Anderson and Reeb2004; Sciascia & Mazzola, Reference Sciascia and Mazzola2008). In emerging markets, due to the market volatility and policy instability, family involvement may show some slightly different characteristics such as more nepotism (Khwaja & Mian, Reference Khwaja and Mian2005), so in this study we pay particular attention to family involvement in emerging markets.

The literature has specified family involvement in three forms: family ownership (e.g., Anderson & Reeb, Reference Anderson and Reeb2004; Chu, Reference Chu2011; De Massis, Kotlar, Campopiano, & Cassia, Reference De Massis, Kotlar, Campopiano and Cassia2015; Tsao, Chen, Lin, & Hyde, Reference Tsao, Chen, Lin and Hyde2009; Yammeesri & Lodh, Reference Yammeesri and Lodh2004), family control (e.g., Barontini & Caprio, Reference Barontini and Caprio2006; Silva & Majluf, Reference Silva and Majluf2008), and family management (e.g., Chang & Shim, Reference Chang and Shim2016; De Massis et al., Reference De Massis, Kotlar, Campopiano and Cassia2015; Ensley, & Pearson, Reference Ensley and Pearson2005). While extant studies have adequately examined the influence of family involvement from an upper-echelon perspective by focusing on the organizations’ high level such as firms’ ownership structure, board composition, and top management team, our understanding of the influence of family involvement at the middle-level, i.e., family members occupying middle-level managerial positions, remains inadequate. Shifting our focus to the middle-level managers is theoretically important because they serve as communication channels bridging lower-level employees and the top management team. They collect information from the bottom of the organization and meanwhile translate strategies defined at higher levels into downward actions (Fenton-O'Creevy, Reference Fenton-O'Creevy1998; Floyd & Wooldridge, Reference Floyd and Wooldridge1994; Guth & Macmillan, Reference Guth and Macmillan1986). Overall, middle-level managers are in charge of carrying out firm polices, supervising frontline employees, taking responsibility of internal operations and control, so they are more likely to influence firm efficiency (Bartlett & Ghoshal, Reference Bartlett and Ghoshal1993).

Filling middle-level managerial positions with family members is a common practice among family firms in which firm owners have more discretion regarding personnel issues and nepotism (employing family members) is tolerated or understood (Birley, Reference Birley2001). In these firms, family members’ participation in managerial activities has a direct impact on the firm's internal management. That said, although family involvement at both top- and middle-level management has important impacts on a firm's operation and performance, the mechanisms through which these two management bodies at different levels affect a firm's managerial outcomes can differ greatly. Therefore, investigating the influence of the degree of family involvement in middle-level management supplements our understanding of the influence of family involvement on firms’ performance, and has important managerial implications for human resource practices in family firms.

To address this issue, we borrowed insights from agency theory (Jensen & Meckling, Reference Jensen and Meckling1976) and organizational justice perspective (Colquitt, Reference Colquitt2001; Colquitt et al., Reference Colquitt, Scott, Rodell, Long, Zapata, Conlon and Wesson2013) to examine how family involvement in middle management (i.e., percentage of family middle managers in the middle management team) leads to distinctive agency problems, exerting a negative influence on a firm's labor productivity. This is a primary indicator of overall workforce performance that has more proximate relation with the functions of middle-level management (e.g., carrying out daily operations, monitoring and motivating employees, and so on) (Delery & Shaw, Reference Delery and Shaw2001). Using a sample of Chinese privately owned family firms, we found that family involvement in middle management was negatively related to the labor productivity of family firms. Moreover, we adopted a multilevel approach to understanding the boundary conditions of this effect. In particular, we examined the moderation effects of three contextual factors at different levels – familial CEO (individual level), firm size (organizational level), and labor mobility (regional level). We found that the negative impact of family involvement in middle management on family firms’ labor productivity existed only when the CEO was a family member, or when family firms were large in size, or when family firms were located in regions with low labor mobility.

These findings make several contributions to the literature on family businesses. First, we expand the scope of family involvement research by supplementing the upper-echelon perspective with a new focus on middle-level management, and investigated this important but underexplored form of family involvement. Our results indicate that middle managers and top-level decision makers differ in their roles in family firms. By examining the impact of the proportion of family members among middle managers, we enrich our understanding of the impacts of family involvement. Second, by integrating the organizational justice perspective with agency theory, we offer a new angle for understanding the phenomenon of family involvement. In this way we contribute to organizational justice by extending a micro theory into a more macro phenomenon, which is a meaningful attempt at micro-macro integration. Third, we introduce multilevel contextual factors in moderating the relationship between family involvement in middle management and family firms’ labor productivity. By taking individual-, organizational-, and regional-level characteristics into consideration, we present a more-comprehensive understanding of when appointing family members as middle managers will be more or less detrimental. In addition, our findings have important managerial implications for human resource practices in privately owned family firms. We reveal that nepotism is harmful overall when selecting middle managers but only holds in certain conditions.

THEORETICAL BACKGROUND AND HYPOTHESES

Agency Theory, Organizational Justice, and Family Involvement

Agency theory has been widely quoted in explaining how family involvement affects firm performance (Dyer, Reference Dyer2006; Jensen & Meckling, Reference Jensen and Meckling1976; Karra, Tracey, & Phillips, Reference Karra, Tracey and Phillips2006). Agency theory suggests that when the principals and agents of the firm are different, agents may engage in activities that, if unchecked, will hurt the principals’ interests due to information asymmetries and self-interest incentives (Jensen & Meckling, Reference Jensen and Meckling1976). Some scholars suggest that family involvement is an effective way to reduce agency cost because it will align the principal-agent goals, build high trust and shared values, facilitate communication and cooperation among owners and family agents, and hence benefit the performance of family business (e.g., Anderson & Reeb, Reference Anderson and Reeb2003; Daily & Dollinger, Reference Daily and Dollinger1992; McConaughy, Matthews, & Fialko, Reference McConaughy, Matthews and Fialko2001). However, this is not always the case. Other studies have demonstrated that family involvement actually exposes family firms to unique agency problems that are even more difficult to resolve due to family relations (Gomez-Mejia, Nunez-Nickel, & Gutierrez, Reference Gomez-Mejia, Nunez-Nickel and Gutierrez2001; Schulze, Lubatkin, Dino, & Buchholtz, Reference Schulze, Lubatkin, Dino and Buchholtz2001). For example, goal incongruence between owners and family agents still exist. Also, adverse selection and shirking are likely to originate from altruism towards family members. Overall, these studies indicate that agency problems in family firms may come in a variety of forms, which are detrimental to firm performance. The current research focuses on one particular form of family involvement – family involvement in middle management – and suggests that distinctive agency threats will occur with an increase in the family middle managers.

In addition, we also integrate the organizational justice perspective (Colquitt, Reference Colquitt2001; Colquitt et al., Reference Colquitt, Scott, Rodell, Long, Zapata, Conlon and Wesson2013) to clarify how family involvement in middle management impacts labor productivity by influencing nonfamily employees’ perception of justice. We integrate this perspective to elaborate on the additional performance threat caused by family middle managers for the following reasons. First, justice is an important organizational factor that directly influences employees’ behavior. The perception of justice fosters employees’ social exchange quality with organizations, and thereby enhances their task performance as well as stimulates their organizational citizenship behavior (Colquitt et al., Reference Colquitt, Scott, Rodell, Long, Zapata, Conlon and Wesson2013). In contrast, a low level of justice perception is likely to incur negative consequences, such as low social-exchange quality and negative job attitudes. Creating organizational justice may be the key to effective management of nonfamily employees, which has been recognized as a critical issue in family firms (Barnett & Kellermanns, Reference Barnett and Kellermanns2006; Chua, Chrisman, & Sharma, Reference Chua, Chrisman and Sharma2003). Second, compared to top managers, middle managers have much more frequent interactions with frontline employees through daily supervision, and thus have a more-direct influence on employees’ work attitude, motivation, and behavior. As far as justice is concerned, middle managers may be an influential factor in employees’ justice perception. Third, in family firms, the violation of justice may be a ramification of family ties (Barnett & Kellermanns, Reference Barnett and Kellermanns2006). Family involvement in middle management could thus amplify the salience of organizational injustice, or in other words increase nonfamily members’ perception of injustice. Overall, integrating the organizational justice perspective in order to study the middle-level management team is well-founded and offers additional explanations for the effect on labor productivity of family involvement in middle management.

The Main Effect of Family Involvement in Middle Management

A central feature of the middle-level managerial position is that it serves as the intermediate level in the firm, just like ‘the filling in the sandwich’ (McConville & Holden, Reference McConville and Holden1999). Middle managers are responsible for the performance of their departments; in doing so, they need to motivate team members to accomplish various tasks on a daily basis (Schulze et al., Reference Schulze, Lubatkin, Dino and Buchholtz2001). This suggests that middle managers find themselves involved in frequent social interactions with both the top management team and lower-level employees in the firm. By analyzing the role of middle managers in these two types of social interactions, we argue that family involvement in middle management may bring unexpected disadvantages to family firms’ labor productivity.

The first type of social interaction occurs between middle-level managers and higher-level managers. Extending agency theory, we anticipate an increase of agency cost, because the owners may assign the middle-level positions to unqualified family members due to nepotism (Ewing, Reference Ewing1965). According to social-emotional wealth theory, families usually have noneconomic goals in addition to economic considerations, such as providing employment for family members and enhancing family cohesion (Cennamo, Berrone, Cruz, & Gomez-Mejia, Reference Cennamo, Berrone, Cruz and Gomez-Mejia2012). However, family firms usually have a limited labor pool; this implies that the family is unable to provide enough qualified members to manage key operations (Dyer, Reference Dyer2006). Under such circumstances, the more family members that are hired as middle managers, the less competent the middle management team will be, thus leading to additional coaching and monitoring costs. Besides, compared to nonfamily members, family middle managers probably capitalize on family ties to gain more leader support and superior organizational resources, but they are less vulnerable to criticism or layoffs when they make mistakes, as they are protected under the umbrella of family ties. That is, the reward and punishment system is biased by family ties and thus will be less effective in holding family managers accountable. Therefore, with the increase of family members occupying middle-level managerial positions, the accountability of the middle management team decreases, thus harming the labor productivity of family firms.

The second type of social interaction occurs between middle-level managers and lower-level employees. Middle managers have to supervise the frontline employees, and their unique family member identity jeopardizes employees’ work motivation. In family firms, the owners usually have the power to influence crucial personnel selection decisions. They may hire family members as managers to create jobs for the family, or to perpetuate family control across generations (Chua, Chrisman, & Steier, Reference Chua, Chrisman and Steier2003; Jaskiewicz & Uhlenbruck, Reference Jaskiewicz and Uhlenbruck2013). In this case, family identity rather than competency is the key determinant of entering the management team. This evaluation and selection process appears to be unfair to nonfamily employees and thus weakens their motivation to seek career advancement within the firm. Studies show that nonfamily employees believe more strongly than family employees that a family member will take over the firm and they will be excluded from senior positions (e.g., Poza, Alfred, & Maheshawi, Reference Poza, Alfred and Maheshawi1997). Poza and colleagues (Reference Poza, Alfred and Maheshawi1997) present evidence that nonfamily managers are less satisfied than family managers with the equity of compensation and how their firms handle growth. In other words, the fact that family members occupy important managerial positions sends the negative signal to employees that their promotion will be less likely. This is a dangerous signal because it affects how employees perceive justice within the organization. A positive perception of justice has been recognized as a critical issue to family businesses (Barnett & Kellermanns, Reference Barnett and Kellermanns2006; Chua et al., Reference Chua, Chrisman and Sharma2003), because it fosters employees’ social exchange quality with organizations, and thereby enhances their task performance, as well as stimulates organizational citizenship behaviors (Colquitt et al., Reference Colquitt, Scott, Rodell, Long, Zapata, Conlon and Wesson2013). Therefore, from the organizational justice perspective, family members’ involvement in middle management jeopardizes nonfamily employees’ perception of justice, and consequently diminishes their work efforts.

In sum, family involvement in middle-level managerial positions contradicts the firm's economic goal and reduces nonfamily employees’ work motivation. The higher the percentage of family managers in the middle management team, the less effective the middle management team will be and the more pronounced nonfamily employees’ perception of organizational injustice. Thus, we propose that:

Hypothesis 1: Family involvement in middle management will be negatively associated with family firms’ labor productivity.

Contextual Contingencies

In emerging markets, organizations are nested in a rapidly changing environment, so how organizations’ internal practices influence firm outcomes depends on various contextual contingencies. Although emerging markets constitute a major growth opportunity, they are also experiencing domestic policy instability, market orientation conflicts, and financial volatility (Arnold & Quelch, Reference Arnold and Quelch1998; Bourgeois, Reference Bourgeois1985). In these unstable and less-predictable situations, it is particularly necessary to incorporate a contingency perspective to understand how contextual contingencies play a role (Fredrickson & Mitchell, Reference Fredrickson and Mitchell1984; Lee & Miller, Reference Lee and Miller1996). We argue that while family involvement in middle management may endanger labor productivity of the family firms by compromising economic objectives and spreading injustice perception, such negative influence may be especially potent or weak across firms under different contingencies. In the following sections we examine contingencies at the individual (familial CEO), organizational (firm size), and regional (labor mobility) levels to add insights into how family involvement in middle management plays a role under different circumstances. We focus on these three contingencies to adopt a multi-level approach to revealing when family involvement in middle management is more problematic and when it is less of an issue. More importantly, we aim to strengthen our arguments that the negative consequence of family middle managers is based on family ties, becomes salient when it disrupts organizational justice, and harms firm performance by decreasing the motivation of nonfamily employees.

Individual Contingency: Familial CEO

The type and quality of relations between top management and middle management may condition the effectiveness of the middle management. The existence of family ties between top and middle management may exert a moderating influence on the relationship between a share of family middle managers and family firms’ labor productivity. In social interactions with the CEO, middle managers must follow instructions from the CEO, and report to the CEO their daily operation and management. However, when the CEO is a family member instead of a professional nonfamily manager, a direct supervisor-subordinate relationship between family members is established. Family middle managers thus may get a free ride or get away with mistakes due to their family ties with the familial CEO (Bruce & Waldman, Reference Bruce and Waldman1990). In this sense, with the family members occupying middle-level managerial positions, the familial CEO will not be able to effectively supervise the middle management team.

Moreover, employees tend to consider family management as nepotism and perceive injustice when they observe the family relationship between the CEO and the middle managers. The firm's daily operations and management require frequent social interactions between the CEO and the middle managers, increasing chances that the familial CEO will demonstrate behaviors that are seemingly more favorable to family members than nonfamily employees (Lee, Lim, & Lim, Reference Lee, Lim and Lim2003). For instance, the familial CEO may delegate more-valuable resources to family middle managers out of altruism but be reluctant to punish poor family middle managers, particularly when such punishment has negative spillover effects on their family relationships outside the firm (Schulze, Lubatkin, & Dino, Reference Schulze, Lubatkin and Dino2003).

Taken together, we thus expect that the negative impact of family involvement in middle management on family firms’ labor productivity will be more pronounced when the CEO is a familial manager rather than a professional manager.

Hypothesis 2: The relationship between family involvement in middle management and family firms’ labor productivity will be moderated by the CEO's family membership such that the negative relationship will be stronger when the CEO is a family member.

Organizational Contingency: Firm Size

Firm size is an important contingency factor that interplays with family involvement in middle management in affecting family firms’ labor productivity. First, compared with small firms, large firms are more dependent on professional management than on family management. Larger firms are commonly associated with more-complex administrative tasks (Zhang & Ma, Reference Zhang and Ma2008). As firm size increases, it is likely that middle managers’ span of control tends to increase (Urwick, Reference Urwick1922). In this sense, larger family firms have to rely more on outside professional managers because the number of family members who are willing to manage and are capable of doing so tend to be limited (Chua et al., Reference Chua, Chrisman and Sharma2003). Thus, when family firms continue to rely on relatively incompetent family members to serve as middle managers even though increased firm size may require more external talents, then a high degree of family involvement in middle management may jeopardize firms’ performance to a greater extent.

In addition, a key difference between small and large firms is the level of regularity and normality (Chu, Reference Chu2011; Li, Zhou, & Zajac, Reference Li, Zhou and Zajac2009). Small firms are generally more flexible in management and implement fewer norms and regulations, so managers in small firms are endowed with greater discretion over managerial decisions. In contrast, large firms are more likely to establish formal protocols and standard operating procedures to regulate employees’ behaviors (Kimberly, Reference Kimberly1976). For example, Chu (Reference Chu2011) suggests that the association between family ownership and firm performance is more significant in small- and medium-sized firms than in large firms. This means that managers in large firms are commonly granted relatively less discretion over managerial decisions. We therefore anticipate an interaction between family involvement in middle management and firm size. Specifically, employing family members may be seen as more legitimate in family firms of small size as in these firm owners have more discretion or even absolute control over managerial issues. Thus, employing family members as middle managers is less likely to trigger nonfamily employees’ perception of injustice and hence their negative consequential reactions. However, in large firms, more-comprehensive norms and procedures are often in place to regulate employees’ behavior and standardize management practices. In these organizations, people act according to formal regulations, and the pursuit of procedural justice may become a salient concern for employees. Therefore, family involvement in middle management in larger firms is more likely to invoke the perception of injustice among nonfamily employees and negatively affect labor productivity.

Taken together, we expect that family involvement in middle management diminishes family firms’ labor productivity to a larger extent among firms of greater size.

Hypothesis 3: The relationship between family involvement in middle management and family firms’ labor productivity will be moderated by firm size such that the negative relationship is stronger in larger firms.

Regional Contingency: Labor Mobility

Local labor market conditions play a key role in shaping people's interpretations and reactions to their current working situations (Mitchell, Holtom, Lee, Sablynski, & Erez, Reference Mitchell, Holtom, Lee, Sablynski and Erez2001). Labor mobility reflects the ease with which people are able to move to different organizations (Gerhart, Reference Gerhart1990). We argue that when a region's labor mobility is low, adverse selection will be more likely to occur. In a region with low labor mobility, it may be difficult for family members to find a job as good as a middle manager in a family firm. In this case family members will make more efforts to get into the family business, and because of kinship family owners are more likely to hire these family members even when they are not sufficiently competent. In addition, when family middle managers make mistakes or perform poorly they are less likely to be laid off because there are fewer job opportunities outside the firm. That is, when family firms are located in regions with low labor mobility, the agency problem is amplified due to family owners’ altruism in taking care of their family members and maintaining their job security.

People may also attach more importance to internal career development when regional labor mobility is low. Due to insufficient job opportunities outside, internal promotion becomes the key means for low-level employees to achieve career development (Gerhart, Reference Gerhart1990). In other words, employees are more likely to implement a long-term career plan in the current firm instead of searching for alternatives in the job market. Under such circumstance, employees may pay particular attention to information related to internal career development and any signal that reveals unfair procedure of appointment or promotion decisions may invoke stronger negative reactions from employees. Traditional models of turnover (e.g., Hom & Griffeth, Reference Hom and Griffeth1994) predict that employees tend to exit the organization when they have low job satisfaction. However, they may get stuck in their current position if job market conditions are not favorable, e.g., low labor mobility (Gerhart, Reference Gerhart1990). In this case, employees may act passively and even engage in counterproductive workplace behavior in order to achieve a balanced exchange with the organization (Cropanzano & Mitchell, Reference Cropanzano and Mitchell2005). Therefore, in regions with lower labor mobility, family involvement in middle management is more likely to induce employees’ perception of injustice as well as their stronger negative response to unfair treatment caused by family management.

Taken together, we expect that family involvement in middle management will have a stronger negative effect on labor productivity in family firms located in regions with lower labor mobility than those located in regions with higher labor mobility.

Hypothesis 4: The relationship between family involvement in middle management and family firms’ labor productivity will be moderated by the regional labor mobility such that the negative relationship is stronger when the labor mobility is lower.

METHODS

Data and Sample

Data used in this study were drawn from the ninth survey of Chinese privately owned enterprises conducted by the Privately Owned Enterprises Research Project Team (POERPT) in 2010. This survey is conducted every two years nationwide. Its purpose is to detect problems in the development of the private economy and provide policy recommendations to authorities. The 2010 survey contained information about family firms, including business structure, corporate governance, succession, labor protection, and other basic statistical facts. Using a multistage stratified sampling procedure, the research team first generated a national representative sample of POEs and then sent questionnaires to the entrepreneurs of the POEs included in the sample. A POE's financial manager was asked to provide basic information about the firm, and firm owners reported other data such as family membership of department administrators and the source of the CEO.

Following previous research on family businesses, we chose observations in which families maintain over 50 percent of the firms’ ownership as our sample (He, Song, Zhu, & Li, Reference He, Song, Zhu and Li2014). After eliminating responses with obvious mistakes or missing values, we ended up with a valid sample of 1,284 private family firms. These firms were distributed throughout nineteen industries, among which 45.25 percent belonged to the manufacturing industry. Regarding business structure, 9.11 percent of the enterprises were sole proprietorship, 6.54 percent were partnership, 72.20 percent were limited liability companies (LLC), and 12.15 percent were joint stock companies (JSC). The average firm age was 9 years.

Variables

Labor productivity

Labor productivity is one of the most suitable indicators of workforce performance (Delery & Shaw, Reference Delery and Shaw2001). In this study, we followed convention in using the logarithm of sales per employee to measure labor productivity (Datta, Wright, & Guthrie, Reference Datta, Guthrie and Wright2005; Huselid, Reference Huselid1995; Iverson & Zatzick, Reference Iverson and Zatzick2011). Specifically, we divided a firm's sales revenue in 2010 by the total number of employees in the firm (Huselid, Reference Huselid1995). We used the logarithm forms of this index as the dependent variable to correct for the skewed distribution.

Family involvement in middle management

Our independent variable, family management, was measured by the percentage of department managers who were related to the entrepreneur's family (Sciascia & Mazzola, Reference Sciascia and Mazzola2008). In the survey questionnaire, entrepreneurs were asked to indicate their relationship with the seven department administrators respectively. The relationships were grouped into five categories: (1) spouses, parents, or children, (2) other lineal relatives, (3) in-laws, (4) friends or schoolmates, (5) no special relationship. We regarded a department manager as a family member if the entrepreneur chose 1, 2 or 3; otherwise the manager was labeled as a nonfamily employee. We then calculated the percentage of family members in middle-level management by dividing the number of familial managers by the total number of department managers.

Familial CEO

To capture whether the supervisor-subordinate relationship between CEOs and department managers overlapped with family ties we created a dummy variable. The value one indicated that the CEO was a family member, and zero otherwise.

Firm size

Consistent with previous research (Li et al., Reference Li, Zhou and Zajac2009; Maury, Reference Maury2006), we used the logarithm of total assets in 2010 as a measure of firm size.

Labor mobility

This regional indicator was not measured in the questionnaire. Instead, we used a third-party source data National Economic Research Institute's (NERI) Index of Chinese Provinces to measure regional labor mobility (Fan, Wang, & Zhu, Reference Fan, Wang and Zhu2011). We chose provincial labor mobility from the many subindicators of the maturity of the elements market. Consistent with the extant literature (Li & Zhang, Reference Li and Zhang2010), we averaged the labor mobility of the previous three years (2007-2009) and used it to measure the level of labor mobility in a province.

Control variables

We incorporated several control variables in our study. First, we controlled for industry. Specifically, we generated eighteen dummy variables based on NBSC (National Bureau of Statistics of China) classifications. At the firm level, we controlled for business structure and firm age. We recoded the categorical business structure variable into three dummy variables indicating whether a firm is a partnership, a limited liability company, or a joint stock company. Firm age refers to the number of years that the firm had operated in China by the end of 2010. In addition, since unions may have an impact on labor productivity (Datta et al., Reference Datta, Guthrie and Wright2005), we added a dummy variable to control for the existence of unions. Lastly, we controlled for the maturity of a firm's governance structure. We coded governance structure as one if a family firm had a board of directors, shareholders’ meetings, and a board of supervisors, and otherwise coded zero (Liang, Chen, & Ge, Reference Liang, Chen and Ge2010). We expected that labor productivity would be higher when family firms had a more-mature governance structure.

RESULTS

Family management at the middle level is by nature related to nepotism (i.e., recruiting family members). Prior studies have not provided any specific statistics about this phenomenon. We therefore decided to first conduct a descriptive analysis before the hypothesis testing to determine whether appointing family members as middle managers is a widely adopted practice in family firms. In our sample (1,284 privately owned family firms), 57.09 percent of family firms had as least one family member as a department manager. Table 1 presents the frequency of using family or nonfamily managers for each type of department among the sample. For all types of department, a certain percentage (at least 9.89 percent) of family firms had at least one family member as department manager. It is interesting to observe the difference among the seven departments. Specifically, family firms are most likely to have family members supervising the financial department (33.02 percent) and purchasing department (36.52 percent), but least likely to appoint family members as the R&D department manager (9.89 percent). Since the financial department and purchasing department deal with a firm's cash flow, family owners may consider a family member more trustworthy in these positions compared to nonfamily members, whereas, the R&D department requires expertise that family members may lack. Family firms are thus more likely to recruit nonfamily professionals as the R&D manager.

Table 2 presents the correlation matrix and descriptive statistics for the major variables. Family involvement in middle management was negatively associated with labor productivity (r = −0.13, p < 0.001), providing basic evidence supporting H1.

Table 2. Correlation matrix and descriptive statistics

Notes: n = 1,284; * p < 0.1, ** p < 0.05, *** p < 0.01.

We used ordinary least square (OLS) regression to test our hypotheses. Because the firms we studied were nested in provinces, we used clustered robust standard errors to estimate the effects of the covariates. Table 3 presents the results of the main effect and the three moderation effects. We first added all the control variables in Model 1. The results showed that a region's labor mobility was positively related to labor productivity of family firms, and larger family firms had higher labor productivity. H1 predicts that family involvement in middle management will be negatively associated with labor productivity. To test H1, we added the independent variable in Model 2. The results showed that family involvement in middle management was negatively related to labor productivity (β = −0.06, p = 0.028). It indicated that with family involvement in middle management increasing by one standard deviation, labor productivity would decrease by 0.02 (equivalent to loss of 10200 yuan per employee). H1 was therefore supported. Comparing Model 2 to Model 1, the ΔR2 was 0.01, indicating that family involvement in middle management explained 1 percent of the variance of labor productivity. In our sample a 1 percent change of productivity means an approximately 1.98 million yuan increment or decrement of sales on average. This indicates that although the additional variance explained by family involvement in management is relatively small, this small variance will still have a dramatic effect on these off-the-list family firms.

H2 predicts that the negative relationship between family involvement in middle management and labor productivity will be stronger when the CEO is a family member instead of a professional manager. As shown in Model 3, the interaction term of family involvement in middle management and familial CEO was not significantly related to labor productivity (β = −0.03, p = 0.311). Thus, H2 was not supported. However, considering that familial CEO is a dummy variable, we further split the full sample and tested the relationship between family involvement in middle management and labor productivity respectively in two subsamples. The results showed that when family members occupied the position of CEO (n = 1151), family involvement in middle management was negatively related to labor productivity (β = −0.11, p < 0.001), whereas when a professional manager was the CEO (n =133), family involvement in middle management was not related to labor productivity (β = −0.04, p = 0.761) (illustrated in Figure 1). It indicated that when the CEO was a professional manager, the CEO would monitor family middle managers more effectively and thus the possible negative consequence caused by family involvement in middle management would be avoided. Notwithstanding that the moderation hypothesis was not supported, in doing so, we found differential effects of family involvement in middle management on labor productivity between firms with a familial CEO and firms with a professional CEO.

Figure 1. The moderation effect of familial CEO on the relationship between family involvement in middle management and labor productivity.

H3 predicts that the negative relationship between family involvement in middle management and labor productivity will be stronger for larger family firms. As shown in Model 4, the interaction term of family involvement in middle management and firm size was negatively related to labor productivity (β = −0.07, p = 0.015), indicating that firm size strengthens the relationship between family involvement in middle management and labor productivity. Furthermore, for large family firms (one SD above mean; n = 357) family involvement in middle management was negatively related to labor productivity (β = −0.13, p = 0.006), whereas for small family firms (one SD below mean; n =389) there was no significant relationship between family involvement in middle management and labor productivity (β = 0.02, p = 0.731) (illustrated in Figure 2). H3 was therefore supported. The nonsignificant relationship found in small family firms shows that when the firm size is small, the practice of appointing family members as middle managers will not hurt the overall workforce efficiency of the firm. Our explanation is that in small family firms, family middle managers may be capable for administrative tasks, and meanwhile family involvement may be viewed as legitimate by nonfamily employees.

Figure 2. The moderation effect of firm size on the relationship between family involvement in middle management and labor productivity.

H4 predicts that the negative relationship between family involvement in middle management and labor productivity will be stronger when regional labor mobility is lower. As shown in Model 5, the interaction term of family involvement in management and labor mobility was positively related to labor productivity (β = 0.07, p = 0.013), indicating that regional labor mobility weakens the relationship between family involvement in middle management and labor productivity. Furthermore, for family firms located in regions with high labor mobility (one SD above mean; n = 202) there was no relationship between family involvement in middle management and labor productivity (β = 0.10, p = 0.139), whereas for family firms located in regions with low labor mobility (one SD below mean; n = 256) family involvement in middle management was negatively related to labor productivity (β = −0.26, p < 0.001) (illustrated in Figure 3). H4 was therefore supported. It is worth noting that the detrimental effect of family involvement in middle management does not exist for family firms located in regions with high labor mobility because on one hand, family owners will be less likely to hire incompetent family members as there are many other job opportunities outside the family firm, and on the other hand, nonfamily employees will react less negatively to unfair treatment as they can exit the current firm and find an alternative job.

Figure 3. The moderation effect of labor mobility on the relationship between family involvement in middle management and labor productivity.

In Model 6 we added the three interaction terms. The results showed that the interaction of family involvement in middle management and firm size was negatively related to productivity (β = −0.08, p = 0.003), and the interaction of family involvement in middle management and labor mobility was positively related to labor productivity (β = 0.08, p = 0.004). This provides further evidence for H3 and H4 in the full model.

Robustness Check

Although our research focus is on family involvement in middle management, it is valuable to explore whether its effect is differentiated from family involvement in top management. Since our sample was comprised of private family firms, many of these firms’ governance structures were relatively underdeveloped. Among our final sample, 53.50 percent established a board of directors. Using this subsample (n = 683), we controlled for family involvement in top management (i.e., measured as percentage of family members in the board of directors), and reran the main effect model. The results showed that family involvement in top management had no significant relationship with labor productivity (β = 0.06, p = 0.113), while family involvement in middle management still had a significantly negative relationship with labor productivity (β = −0.11, p = 0.003). We are therefore confident that family involvement in middle management will negatively impact family firms’ labor productivity despite family involvement in top management.

Second, since family firms are nested in different provinces, labor mobility is a province-level variable. As such, the moderating effect of labor mobility on the relationship between family involvement in middle management and labor productivity is a cross-level interaction. We therefore constructed a hierarchical linear model to test this interaction effect. Specifically, we chose labor mobility as the group-level variable. We followed Hofmann and Gavin's (Reference Hofmann and Gavin1998) method and centered the individual-level predictor using the grand mean. This approach made it easier to interpret the results as well as control for individual-level effects when testing the incremental effects of group-level variables. The results of the hierarchical regression showed that labor mobility weakened the negative relationship between family involvement in middle management and labor productivity (b = 0.06, p = 0.024). This finding was consistent with previous results regarding H4.

Furthermore, we generated a dummy variable to indicate a region's labor mobility. Business competition is stronger in highly developed regions than it is in less-developed regions. Correspondingly, the labor market is also more mature. In China, the division of coastal provinces and inland provinces is a typical demarcation line of economic development. We therefore predicted that the negative relationship between family involvement in middle management and labor productivity would be stronger in family firms located in inland regions than those located in coastal regions. We coded inland regions as a dummy variable. Inland regions were coded as zero if the location of a family firm was in Liaoning, Beijing, Tianjin, Shandong, Jiangsu, Shanghai, Zhejiang, Fujian, Guangzhou, or Hainan, and one otherwise (Li et al., Reference Li, Zhou and Zajac2009). In the subsample of inland firms (n = 640), the regression result showed that family involvement in middle management was negatively related to labor productivity (β = −0.10, p = 0.011). However, in the subsample of coastal firms (n = 644), family involvement in middle management had no significant relationship with labor productivity (β = −0.002, p = 0.955). This result was consistent with our prediction, providing further evidence for the region effect.

DISCUSSION

This research expands studies on the relationship between family involvement and firm performance by directing scholarly attention from upper-echelon to middle management. We borrowed insights from agency theory and the organizational justice perspective and theorized that family involvement in middle management, indicated as percentage of family members among middle managers, would incur alternative forms of agency costs and perceptions of injustice among employees and would thus adversely affect family firms’ labor productivity. Moreover, we further embedded this relationship into organizational and regional economic contexts and examined how firms’ leaders, organizational characteristics, and the features of the local labor market could exacerbate or alleviate the negative impact of family involvement in middle management on labor productivity. We found that the negative effect of family involvement in middle management existed only when the CEO was a family member, or when the size of the firm was large, or when the firm was located in a region with low labor mobility.

Theoretical Contributions

The present study contributes to the existing literature in the following aspects. First, our study draws attention to the role of family involvement in middle management. To the best of our knowledge, this study is the first to focus on family managers at the middle level and provide empirical evidence on its role on family firms’ labor productivity. Family involvement is one of the most salient characteristics of family businesses. Researchers have devoted much effort to investigating the effects of family involvement in ownership, control, and management on firm outcomes. Although these efforts have yielded rich evidence that highlights the importance of family involvement, most prior studies focus on positions at the strategic apex of organizations such as family owners, family board members, and family CEO. Family members in these positions play a critical role because they have great influence on family firms’ strategic decisions, which determine the sustainment as well as the development of a family business. However, compared with top-level ‘big names’ at the strategic apex, middle managers usually play a more-important role in carrying out the policies and decisions made by corporate leaders (Floyd & Wooldridge, Reference Floyd and Wooldridge1994, Reference Floyd and Wooldridge1997). They are mainly responsible for internal daily operations and control, and the composition of the middle management team has an immediate and direct impact on the efficiency of family firms. Adopting the perspectives of agency theory and organizational justice, this study reveals that family involvement in middle management is detrimental to family firms’ labor productivity.

Second, we incorporated the organizational justice perspective into our theorizing, providing a micro foundation for the effect of family involvement. Most previous studies on family involvement do not explicitly consider the role of nonfamily employees. In fact, family involvement may influence firm performance by affecting nonfamily members’ motivation, attitude, and behavior. This is particularly important when we look at family middle managers because they are responsible for supervising and motivating frontline employees. By integrating the organizational justice perspective into this study, we offer a new angle for understanding the phenomenon of family involvement. In this way, the study also contributes to organizational justice by extending a micro theory into a more macro phenomenon, which is a meaningful attempt at micro-macro integration.

Third, we explore the boundary conditions of familial CEO, firm size, and regional labor mobility. Our study shifts the focus from the higher level to the middle level, proposing three important contingencies for understanding how this internal practice at the middle level interplay with other factors, which can even be factors outside of the organization, to jointly affect the performance of the family business. We argue that these contingencies affect the quality of middle-level managers’ social interactions with other members within the organization and hence affect the family firms’ labor productivity. In doing so, we paid particular attention to the role of middle managers facing different social actors in the organization. Habbershon, Williams, and MacMillan (Reference Habbershon, Williams and MacMillan2003) propose a unified systems model of family business to highlight the importance of social interactions among different members in the family organization. In line with this perspective, we found that such negative impact existed only when the CEO has a familial identity, the firm is large in size, or the external labor market has low mobility. These findings reveal the situations in which the negative consequence of family involvement in middle management is more pronounced, and they extend our understanding of the interactions among different shareholders related to family businesses.

Fourth, we adopted a multilevel approach to exploring the boundary conditions of the main effect in this research. The cross-level interaction effect between family involvement in middle management and a region's labor mobility clearly shows how family businesses, just like other economic organizations, are nested in broad social institutions. The association between the firm and the region implies that this internal practice may generate distinct effects on labor productivity given the different situations of the external labor market. Although a family business has a unique way of dealing with external institutional constraints and focus on its noneconomic goals (e.g., Berrone, Cruz, & Gomez-Mejia, Reference Berrone, Cruz and Gomez-Mejia2012), our study implies that regional influence still penetrates into the family business. What is more, adopting a multilevel approach does not simply refer to our investigation of the cross-level interactions, but also means efforts in bridging perspectives at different levels to address the same research question.

Limitations and Future Research Directions

This study inevitably has several limitations. First, we cannot safely draw a casual inference from our findings based on the cross-sectional data used. One major problem of using cross-sectional data is reversed causality, which means that reduced labor productivity may lead to a higher level of family involvement in middle management but not the vice versa. However, we suggest that this is unlikely. First, when the financial manager in each firm reported their performance information as a ‘snapshot’, middle-level managers had usually been working in their positions over a period of time. This reasonable inference of the reality suggests that it is more likely that our independent variable precedes the dependent variable in time. Second, a rationale to explain the reversed causality is that family businesses hire family members in order to cut costs or improve revenue in response to reduced labor productivity. However, previous research has implied that hiring family members is commonly not an attempt to achieve economic objectives (Cennamo et al., Reference Cennamo, Berrone, Cruz and Gomez-Mejia2012). Thus, in spite of the challenges from using cross-sectional data, we suggest that this secondhand large dataset is the best we can currently utilize to answer the research question, and it is more likely that our proposed relationship instead of the reversed causality remains.

Second, we tested our hypotheses only based on a sample of Chinese private family firms, and scholars could examine the generalizability of our findings in other emerging markets such as the BRIC (Brazil, Russia, India, and China) countries or SIVETS (Colombia, Indonesia, Vietnam, Egypt, Turkey, and South Africa). Although the theoretical pillars that support our arguments are relatively context free, it is possible that family involvement in these countries may demonstrate different characteristics, so its effect on labor productivity varies. In addition, we only focused on private family firms whose governance structures are relatively underdeveloped and in which nepotism is more likely to be a severe management problem. However, in public family firms, where the firm's governance structure is well developed, the possible negative influences of family involvement in middle management may be weakened.

Third, we must acknowledge the limitation that we did not directly measure employees’ perception of injustice although we used it as one of the major underlying arguments in the study. Without the measure we cannot completely rule out alternative explanations of the negative effect we found, although empirical evidence of the three interactions effects are consistent with the injustice reasoning. This limitation is due to the use of the secondhand data, because it does not provide any justice-relevant information that we can use to test the underlying mechanism. We strongly encourage scholars who are interested in family management to include the measure of justice perception in future research to further examine this important argument.

Fourth, future research could explore how family members working in different functions may bring about different impacts on firm performance. For example, although approximately one-third of the private family firms tend to hire a family member as the manager of their financial department, it may not be a wise decision because the financial department requires high expertise and the financial manager ought to be independent and objective in dealing with financial issues. Due to the existence of family ties the financial manager may be biased in his/her decision making, which may endanger a firm's long term economic performance.
