Comparative institutional analysis of pension policy: debates and insights

The 1990s saw growing academic interest in East Asian welfare states. Inspired by Esping-Anderson's (Reference Esping-Andersen1990) welfare regime approach, scholars sought to identify a welfare model specific to East Asia. For example, the cultural perspective focuses on the impact of Confucianism and explores the familialism inherent in such social policies (Jones, Reference Jones1990, Reference Jones and Jones1993; Rieger and Leibfried, Reference Rieger and Leibfried2003). The productivist (or developmentalist) account explains why East Asian welfare states prioritise economic growth over social redistribution in an attempt to catch up with the advanced industrialised countries (Holliday, Reference Holliday2000, Reference Holliday2005; Holliday and Wilding, Reference Holliday, Wilding, Holliday and Wilding2003; Kwon, Reference Kwon and Kwon2005; Lee and Ku, Reference Lee and Ku2007). Both explanations put private responsibility ahead of public support in welfare provision. Whilst highlighting important aspects of the various East Asian welfare states, these accounts tend to over-simplify the variety of their features without much empirical endorsement. As Esping-Andersen (Reference Esping-Andersen1997) points out, East Asian welfare states are still engaged in the process of institutional building and consolidation, which may take some time to complete. For a region characterised by constant institutional transformations, previous attempts to identify a unique East Asian model have failed to produce fruitful insights. The preoccupation with the ‘welfare modelling business’ (Abrahamson, Reference Abrahamson1999) or ‘familes of nations’ (Castles, Reference Castles1993), further obscures the observation of institutional features and policy dynamics of specific social security domains such as pensions.

Fortunately, this shortcoming has attracted attention in recent pension policy research that turned to the configurations of public–private pension mixes and the policy choices embedded in specific welfare regimes (Huber and Stephens, Reference Huber and Stephens2001; Rein and Turner, Reference Rein, Turner, Rein and Schmähl2004; Ebbinghaus and Gronwald, Reference Ebbinghaus, Gronwald and Ebbinghaus2011; Ebbinghaus and Wiß, Reference Ebbinghaus, Wiß and Ebbinghaus2011). Leading international organisations also heeded the contextual diversity (Asian Development Bank, 2012; OECD, 2013). One exemplary report by the World Bank (2016) gives an extensive analysis of the ageing problems and the associated policy issues including retirement income in East Asia. Whilst its previous report (World Bank, 1994) controversially overweighed private pensions against their public counterparts for the sake of risk diversification, the World Bank has gradually shifted to a stance in favour of a multi-pillar model characterised by joint public–private collaboration in old-age security (World Bank, 2008; cf. Zhou and Shi, Reference Zhou, Shi, McBride and Evans2017). This course change reflects the realisation that the replacement of state pensions by private ones alone is no panacea for the ageing problem, as evidenced by the latter's vulnerability to financial market risks and the tendency to exacerbate inequality of old-age security. Even the Chilean policy conversion from a pay-as-you-go (PAYG) pension system to a fully funded alternative in 1981 – once acclaimed as a model for pension privatisation – required large-scale reform in 2008 due to high administrative costs, the exclusion of large population segments and other unforeseen drawbacks (for an overview of pension privatisation, see Orenstein, Reference Orenstein2008, Reference Orenstein2013). These ambivalent outcomes advise caution against the alleged merits of liberalisation and individual choice associated with the privatisation arguments.

Moreover, Western pension reforms have shown that countries with earnings-related PAYG public pension schemes tend to circumscribe the accretion of private provision in pensions, whereas those with a multi-pillar system (in which universal flat-rate public pension schemes provide minimum economic security) assign private pensions a principal role but simultaneously prescribe state regulation in their programmatic implementation (Ebbinghaus and Gronwald, Reference Ebbinghaus, Gronwald and Ebbinghaus2011; Leisering, Reference Leisering2011). Incremental change of the various pension systems takes place on the premise that public responsibility for pension provision and regulation remains pivotal for retirement income maintenance. These reform endeavours further indicate that no universal one-size-fits-all paragon exists for pension reform, and each country must determine a suitable re-arrangement of public–private pension composition to generate synergy effects, conditioned by its existing institutional frameworks and the characteristics of accessible labour and capital markets.

The preceding discussion points to the necessity of identifying the institutional structures of distinct pension systems and their relative strengths and weaknesses for East Asian countries. A focal shift to a comparative policy analysis can untangle the historical developments of the respective pension systems and assess their impact on old-age security outcomes. This is something the current studies of East Asian welfare have yet to address, whilst research by international organisations can equally benefit from the present study's highlighting of the institutional structures and historical origins of East Asian pension policies. The analytical strength of the proposed approach lies in reflecting the close interplay of public–private pensions by drawing a distinction between different providers (pillars) of various pension tiers (cf. Immergut and Andersen, Reference Immergut, Andersen, Immergut, Andersen and Schulze2006; Jochem, Reference Jochem, Clasen and Siegel2007).Footnote ³ This is an important consideration given the long history of pension policy in countries such as Japan and Korea, which incorporated occupational pensions on top of the public ones at the outset of welfare state development (Yi, Reference Yi2007; Estévez-Abe, Reference Estévez-Abe2008). Hong Kong and Singapore trod a different path and set up provident funds under the government's supervision. These instances suggest that the boundary between public and private pensions is never clear-cut as the proper operation of private pension schemes often requires state regulation (Ebbinghaus and Wiß, Reference Ebbinghaus, Wiß and Ebbinghaus2011; Leisering, Reference Leisering2011; Whiteside and Ebbinghaus, Reference Whiteside and Ebbinghaus2012). As such, the pillar–tier demarcation offers heuristic potential to portray a broader picture of pension policy development without losing sight of nuanced public–private enmeshment.

This appeal becomes clear when considering that some East Asian pension systems with earnings-related social insurance schemes tend to distance themselves from occupational and private pension schemes, whilst others adopt the opposite or hybrid paths (Bonoli and Shinkawa, Reference Bonoli, Shinkawa, Bonoli and Shinkawa2005; Choi, Reference Choi2008). As such, variety in the gestalt of the mixtures traces back to a long history of collective endeavours to initiate private pensions along with public pensions through the development of East Asian welfare states. Diverse approaches depart from various institutional frameworks of public–private pension mixes to address the challenge of economic insecurity in retirement due to population ageing. The scope and extent of public–private mixes in pensions reveal much about the ways in which old-age security is safeguarded by pertinent institutional regulations. It thus follows that a comparative institutional analysis can shed light on the cross-national variation amongst East Asian pension systems regarding the public–private division of labour for old-age security. One such undertaking includes a comparison of the pension institutional structures as well as the measurement of their policy outcomes by key policy indicators.

The following two sections present historical and indicator analyses, taking into account the historical paths to different configurations of public and private pension provisions. This is then supplemented with a comparison of key indicators covering three major aspects – pension adequacy, financial sustainability and the significance of private pensions – to outline the discrete policy outcomes of the respective pension patterns and their impacts on the old-age security.

Three worlds of pension system development in East Asia

East Asian pension systems have undergone significant reforms over the past few decades, but each country exhibits a certain continuity of institutional logic. Japan and Korea feature a fully fledged tier of occupational pensions which primarily favour employees of large conglomerates (keiretsu in Japan and chaebol in Korea), together with another strong tier of public pensions in the form of social insurance that covers the whole population. Meanwhile, China and Taiwan both offer pension systems composed of a hefty public pension tier, with substantial stratification in benefit levels amongst various occupation groups. Although occupational pensions are on the rise in both cases, the overall development of this segment is insufficient to ensure old-age security. Finally, Hong Kong and Singapore stand out as a prototype for pension systems operating solely with fully funded individual accounts (provident funds), jointly financed by employers and workers. Out of their residualist ideology with a distinct antipathy for public financing of social provisions, both governments have refrained from introducing any public pensions, with means-tested assistance only available to the elderly poor.Footnote ⁴

Institutional structures of three pension patterns in East Asia

Dualist pension systems share the burden between public and corporate pensions. In Japan, earnings-related pension schemes were introduced for public servants and military servicemen in the late 19th century, and these schemes were later merged as the Mutual Pension Schemes (MPSs) (Shinkawa, Reference Shinkawa2005b; Yano, Reference Yano2012). The Workers’ Pension scheme emerged in 1942 and extended its coverage to become the Employees’ Pension Insurance (EPI) scheme. In 1960, the government introduced National Pension Insurance (NPI) to cover the remaining population still not included under the MPSs or EPI. These legislative efforts produced a structure of different social insurance pension schemes fragmented along occupational divisions. The first attempt at integration came with the introduction of a universal Basic Pension scheme in the 1980s, merging the financial reserves of the NPI with those of other schemes (Shinkawa, Reference Shinkawa2005b; Yano, Reference Yano2012). Today, this universal scheme constitutes the cornerstone of Japan's public pensions, supplemented by the three contributory pension schemes (NPI, EPI and MPSs).

However, these broad-coverage public schemes provide low benefit levels, leaving room for corporate pensions to top up retirement income. Early schemes dating from the late 19th century received official recognition in 1935 as the Retirement Allowance (Yamazaki, Reference Yamazaki1988; Shinkawa and Pempel, Reference Shinkawa, Pempel and Shalev1996; Nishinarita, Reference Nishinarita2009; Krämer, Reference Krämer2013). After the Second World War, corporate pensions gained further momentum, along with the development of the public pension system. In addition to the Retirement Allowance, two defined-benefit (DB) corporate pension schemes, namely the Tax-Qualified Pension Schemes (TQPSs) and Employees’ Pension Funds (EPFs), came into operation (Nishinarita, Reference Nishinarita2009). However, ongoing economic liberalisation and subsequent financial difficulties forced a structural overhaul of these DB corporate pension systems with the introduction of two new corporate pension laws in 2001: the Defined-Benefit Law (the DB law) and the Defined-Contribution Law (the DC law) (Nishinarita, Reference Nishinarita2009; Yeh and Shi, Reference Yeh, Shi, Mok and Lau2014). The DB law stipulated two new types of pension plans: contract type and fund type.Footnote ⁵ The former aimed to replace the TQPSs, and was targeted at small and medium-sized enterprises (SMEs) with no minimum number of members required, whilst the latter replaced the EPFs with an application requirement imposed on companies with at least 300 employees. Meanwhile, the DC law, the Japanese equivalent of US-style 401k plans, attempted to reduce labour costs and shift financial risks to individuals by introducing individual-type and corporate-type pension plans. The former was designed for those under 60 years of age insured under category No. 1 (self-employed) and under the EPI, i.e. those without other corporate pension plans. The latter targeted those insured under category No. 2, i.e. those covered by the EPI with employer-paid contributions.

Korean public pensions initially covered only government employees, military personnel and public school teachers. In contrast, private-sector employees only had access to the Retirement Allowance (i.e. severance pay) under the 1954 Labour Standards Act (Yi, Reference Yi2007; Phang, Reference Phang, Yang and Klassen2010). Political democratisation in the 1980s led to the legislation of the National Pension Insurance Act to cover more private-sector employees, and this was extended later to cover the self-employed and peasants (Hwang, Reference Hwang2006). However, the 1997 Asian Financial Crisis forced the government to reduce NPI benefit levels drastically, from 70 per cent in 1988 to 40 per cent in 2007. To stave off the immediate impacts of labour market deregulation and old-age poverty, the government established a nearly universal non-contributory pension in 2007, the Basic Old-age Pension scheme, providing flat-rate benefits to 70 per cent of elderly people (equivalent to 10% of average incomes under the NPI) (Shin and Do, Reference Shin and Do2014).

Following the 1997 Asian financial crisis, the Korean government revamped corporate pensions. Whilst the Retirement Allowance initially acted as a form of severance pay for unemployment compensation and retirement income, this function declined after the introduction of unemployment insurance and the NPI scheme (Phang, Reference Phang, Yang and Klassen2010). Furthermore, as workers laid off from bankrupt enterprises had little recourse to recover severance, the government passed the Employees’ Retirement Income Security Act (ERISA) in 2005 to restructure the corporate pension system. Three new corporate pension schemes are now available: a DB scheme, a DC scheme and Individual Retirement Accounts (for firms with fewer than ten employees).

By contrast, a statist pension system is characterised by the dominance of public earnings-related pension schemes with high replacement rates, rendering private corporate pensions rather dispensable. The centrepiece of Taiwan's pension system is a good example, consisting of several occupationally fragmented contributory pension schemes including the Military Servicemen's Insurance Scheme established in 1953, along with the Government Employee Insurance for Civil Servants and the Labour Insurance for Workers introduced in 1958. This fragmented pension structure remained largely intact even after democratisation in the late 1980s. Democratic competition between major political parties led to the introduction of various non-contributory pension schemes for different population groups including elderly farmers and middle- and low-income elderly people, followed by the NPI scheme that came into force in 2008 to cover those excluded from the existing programmes (Yeh, Reference Yeh2014). Taiwan currently features five pension schemes for different occupational groups, including four contributory pension schemes, and one non-contributory pension scheme for peasants aged 65 and older.

Given the predominance of public pensions, non-state pensions have never played a significant role in Taiwan. Although corporate pensions appeared in the 1950s, their operation depended crucially on the enterprises’ voluntary participation. The introduction of the Labour Standards Act (1984) turned existing corporate pension schemes into mandatory DB plans with lump-sum payments, which became known as the Labour Retirement Allowance. However, fewer than 5 per cent of retired workers qualified for such corporate pension benefits due to stringent entitlement rules (Yeh, Reference Yeh2016). To address this problem, the Labour Pension Act was introduced to replace the DB Labour Retirement Allowance with DC Individual Retirement Accounts in 2004. Even so, corporate pensions remain a bench player in Taiwan.

Meanwhile, the Chinese pension system consists of three major schemes designed for different occupational (or population) groups. The Urban/Rural Resident Basic Pension Insurance constitutes the basic pillar, covering nearly 513 million people by the end of 2017.Footnote ⁶ In essence, this new scheme incorporates the existing two programmes covering urban and rural residents. It is a fully funded form of social insurance, supplemented by basic pension guarantees from the central government and various supplemental benefits from local governments. Pension eligibility is conditional on 15 years of contributions. The second major scheme, urban worker pension insurance, has been operating since the socialist era but has undergone fundamental overhaul in the last two decades. In its current form, this scheme covered 379 million employees in 2016, approximately 48.8 per cent of the total national workforce (Ministry of Human Resources and Social Security, 2016). The institutional structure features two tiers: the PAYG social pooling requires a contribution rate of 20 per cent of the employees’ gross wages, and the fully funded individual account charges an additional 8 per cent, with contributions shared equally by employers and employees. In addition, in 2004 the government launched pilot schemes for voluntary enterprise and individual pension savings arrangements. Enterprise Annuities are voluntary occupational plans with fully funded defined contribution accounts. Employers can contribute up to 4 per cent of payroll, whilst the combined company and employee contribution are limited to one-sixth of employees’ total salary expenses for the previous year. They are established as a trust that can take the form of either an internal or external trustee model. Enterprise Annuity schemes have primarily been adopted by large, profitable, mostly state-owned enterprises, with total assets amounting to RMB 769 billion in 2015.Footnote ⁷

Finally, the individualist pension system subscribes a loose regulatory role to the state that sets a statutory framework by which individuals accumulate retirement income in financial markets. Rather than state-managed and earnings-related contributory pension schemes, Hong Kong or Singapore rely on centrally or commercially managed provident funds. In 1955, Singapore launched the Central Provident Fund (CPF), the centrepiece of the social security system. Its introduction was partly due to the reluctance of the colonial government to establish a programme that would incur huge public expenditures, and partly due to its appeal to facilitate capital accumulation (Ramesh, Reference Ramesh and Kwon2005). The CPF is a DC scheme, and enrolment is mandatory for all employed Singaporeans. The CPF covers compulsory retirement savings along with medical care and housing, and has not significantly changed since its inception. In 2016, the CPF contribution rate was set at 37 per cent of total wages (17% for employers, and 20% for employees).

The cornerstone of the Hong Kong pension system is a non-contributory scheme which began operation in 1973 with very limited benefit levels (Chan, Reference Chan2011). Later developments saw the enactment of the Occupational Retirement Scheme Ordinance for private workers and pension schemes for civil servants, although both covered barely one-third of the total workforce (Chou, Reference Chou, Fu and Hughs2009). In the 1990s, a pension debate emerged with reference to the soaring social expenditures due to population ageing. Different plans were considered, even including the introduction of a contributory pension scheme. However, this policy discussion coincided with Hong Kong's return to the People's Republic of China, and the Beijing government was focused on the sovereignty transfer and showed little interest in assuming direct responsibility for social security (Ramesh, Reference Ramesh2004; Chan, Reference Chan2011; Tang, Reference Tang, Midgley and Piachaud2011). A consequent compromise led to the introduction of the Mandatory Provident Fund (MPF) in 2000, a compulsory individual saving account with the contribution rate set at 10 per cent of wages borne equally by employees and employers (Yu, Reference Yu2007). Workers with monthly wages below HK $7,100 (approximately US $910) are exempted, as their full contribution is borne by their employers. In contrast to the Singaporean CPF, the MPF is a privately managed scheme operated by the trustees and other service providers.

Table 1 summarises the institutional arrangements of public–private pension mixes in the six East Asian welfare states considered. The three patterns of pension composition show staunch institutional resilience to date, despite challenges posed by population ageing and financial shortfalls. Although each case has initiated several reform measures in response, none has yet essentially altered the institutional logic underlying the public–private partnerships for old-age security. China and Taiwan have launched several rounds of reforms tinkering with public pensions but have never seriously considered private provisions as an alternative. Japan and Korea followed suit, but remained highly reliant on the back-up of occupational pensions. Finally, the public in Hong Kong (and Singapore to a lesser extent) are increasingly concerned about insufficient protection for their old age, but face obstinate government resistance to any radical overhaul. Adherence to the respective principles of this public–private mix implies that certain enduring institutional forces impact the scope and extent of each pension pattern.

Various outcomes of public–private pension mixes in East Asia

Given the institutionalisation of specific pension mixes in the three patterns identified in East Asia, the following analysis aims to compare their policy outcomes through pension policy indicators. Social indicators initially aim to measure and monitor the level and degree of social progress and social wellbeing across time and space, but later find wide application for ‘evaluating a country's level of social development and for assessing the impact of policy’ (Atkinson et al., Reference Atkinson, Cantillon, Marlier and Nolan2002). By developing concept-driven indicators, policy analysts can inspect policy changes and measure individual and societal wellbeing (Noll, Reference Noll and Genov2004). Here we take several pension indicators to foreground the features of macro-level pension developments, and assess their impacts on old-age security. This helps explain the institutional strengths and weaknesses of various public–private pension mixes in East Asia.

Our indicator choice relates to three major aspects.Footnote ⁸ Since pension reforms aim to provide adequate income retirement without jeopardising their own institutional stability, two criteria matter for the evaluation: pension adequacy and financial sustainability (Chybalski and Marcinkiewicz, Reference Chybalski and Marcinkiewicz2016; Been et al., Reference Been, Caminada, Goudswaard and van Vliet2017). The most essential indicator for this purpose is the pension replacement rate that reflects the income allocation over the lifecycle (European Commission, 2015; OECD, 2015; Chybalski and Marcinkiewicz, Reference Chybalski and Marcinkiewicz2016). In this vein, another indicator, the old-age poverty rate, illustrates to what extent the pensions protect elderly people against destitution (European Commission, 2015; Chybalski and Marcinkiewicz, Reference Chybalski and Marcinkiewicz2016). Whilst these two indicators focus on the benefit generosity of a pension system, other indicators related to a system's financial sustainability are equally important: contribution rates and (net) pension wealth, which can duly demonstrate the balance between pension revenues and liabilities (OECD, 2013, 2015). Furthermore, an institutional analysis of public–private pension mixes must take private pensions into account. Where private pensions prevail, they assume an important role in supporting old-age security that the state may be reluctant (or unable) to fill. If we are to understand private roles in old-age security, the inclusion of two indicators, coverage and the size of private pension assets, will pinpoint the position of private pensions and their significance in the various pension systems (Queisser et al., Reference Queisser, Whitehouse and Whitefold2007; World Bank, 2016).

Table 2 begins the evaluation of pension adequacy by comparing the net replacement ratesFootnote ⁹ of mandated pension schemes in six East Asian cases, defined as the ‘individual net pension entitlement divided by net preretirement earnings, taking account of personal income taxes and social security contributions paid by workers and pensioners’ (OECD 2013, 2015). In the individualist pension system, Hong Kong and Singapore feature mandated provident funds offering 36.8 and 42.1 per cent of men with average income, respectively. These mandated schemes’ replacement rates are determined by individual workers’ contributions and their return rates. In the Japanese and Korean dualist pension systems, only mandated social insurance pension schemes and non-contributory ones are included to calculate the replacement rates. Corporate pension schemes are conceived of as a part of voluntary private pensions even though some are mandated occupational pensions. The replacement rates of these social pension insurance schemes for insured persons with average income are lower, set at 40.8 and 45.2 per cent, respectively. The introduction of basic pensions has generally supported low-wage earners. Overall, the low benefit levels of public pension schemes in Japan and Korea have to be compensated by sophisticated corporate pension schemes. By contrast, the social pension insurance schemes in Taiwan and China offer fairly generous benefits to retirees, at respective replacement rates of 73.2 and 84.7 per cent for average wage earners. However, the apparent generosity of retirement income in both cases disguises inherent inequality amongst different groups. Taiwan introduced the contributory NPI in 2009 in support of low-wage earners, but its benefit level remains insufficient for economic security. China's pension system features even more serious inequality amongst various occupational groups and across geographic regions, due to the fact that a substantial proportion of pension benefits depend on the financial support of local governments.

Table 2 further outlines the state of old-age poverty risk.Footnote ¹⁰ The East Asian countries under scrutiny offer a mixed picture. Japan has the lowest elderly poverty rate, whilst that of Korea is fairly high. A reasonable explanation is Japan's early introduction of public pensions that have matured over time, whereas Korea's NPI for private workers came much later in 1988. The same rationale holds for the puzzling phenomenon of high old-age poverty risks in statist pension systems despite their high net replacement rates. The expansion of pension schemes in Taiwan and China in recent decades had a delayed impact on poverty reduction. The individualist pension system features the highest old-age poverty risk, as retirees rely on very modest DC pension benefits. This issue has aroused considerable public concern about the hardship of elderly people in Hong Kong and Singapore (Ng, Reference Ng2011; Commission on Poverty, 2017). Although we would expect a negative relationship between the replacement rate and elderly poverty, Table 2 provides little ground for this assumption (cf. also Been et al., Reference Been, Caminada, Goudswaard and van Vliet2017). This incongruity is mainly due to the pubertal state of the East Asian pension systems that have yet to unfold their sustentative effects on old-age security.

Tables 3 and 4 proceed to the comparison of the contribution rates and net pension wealth. Theoretically, a statist pension system with strong pension insurance would feature higher contribution rates and pension wealth than its individualist and dualist counterparts (Bonoli, Reference Bonoli2003). However, the results in Table 3 are somewhat vague owing to the institutional disparity of the respective pension systems. For example, the contribution rate of the Singaporean CPF is almost four times that of Hong Kong's MPF, largely because it is a comprehensive scheme covering retirement, housing, health and education. Meanwhile, pensions in China have a higher contribution rate than those in Taiwan because the former assign heavy financial responsibility to enterprises. As for the different contribution rates between Japanese and Korean pension schemes, the aforementioned factor of varied institutional maturity still applies. The Korean pension system is relatively immature and prone to change.

Net pension wealth

As an indicator, net pension wealth is related to pension system liabilities, denoting the significance and size of mandatory public pensions (OECD, 2013: 32). Table 4 shows low net pension wealth in countries with individualist and dualist pension patterns. These pension systems feature lower net pension wealth than their social insurance counterparts. The above comparison points to a crucial institutional idiosyncrasy often overlooked by the scholarship of East Asian productivism, namely the predominance of mandatory public pensions in statist pension systems over dualist pension systems (cf. Holliday, Reference Holliday2000; Holliday and Wilding, Reference Holliday, Wilding, Holliday and Wilding2003). Indeed, our analysis highlights a subtle but crucial distinction between these two types in terms of the public–private mixes: social pension insurance schemes figure very differently between statist and dualist pension systems, implying various weight attached to private pensions.

This point becomes clear with Table 5 which turns to the coverage of private pensions and the size of private pension funds. Coverage is measured as the percentage of the working population aged 16–64 covered by private pension plans, which indicates the role private pensions play in future retirement income (De Deken, 2013: 280). Hong Kong's MPF and the Singaporean CPF show high respective coverage rates of 78.9 and 84 per cent. The seemingly unimpressive coverage of private pensions in Japan (25.28%) and Korea (37.7%) is most likely due to missing data, including those of some corporate pensions based on labour contracts (Yamazaki, Reference Yamazaki1988; Nishinarita, Reference Nishinarita2009). For instance, despite its heavyweight, the Japanese corporate pension system does not account for the Retirement Allowance.Footnote ¹¹ The same data inconsistency appears in statist pension systems as well, reflected in the unexpectedly high coverage of Taiwan's private pensions. The preceding section documents the transformation of Taiwanese corporate pensions from DB to DC individual accounts in 2005, leading to an increase in the coverage of corporate pensions, but this by no means enhances their impact because the contribution rates of the DC individual accounts remain low, ranging from 2 to 6 per cent of gross wages. This in turn leads to extremely low replacement rates – well below 10 per cent of wage levels during employment (Yeh, Reference Yeh2016). The discrepancy between coverage increase and low contribution rates in Taiwanese private pensions results from the reluctance amongst SMEs to bear non-wage labour costs.

Table 5 also indicates the size of private pension assets, measured in terms of financial assets as a percentage of GDP, to evince the magnitude of private pensions as well as the degree of financialisation of retirement income (De Deken, Reference De Deken2013). Figures showing private pension assets relative to the national economy are higher in countries with individualist pension systems, amounting to 37.8 per cent in Hong Kong and 60 per cent in Singapore, respectively. This percentage gap is largely due to Hong Kong's more recent introduction of MPF, which has yet to accumulate assets comparable to those in Singapore. The huge size of private pension assets indicates the financialisation and individualisation of retirement risk exposure for the residents. When shifting attention to the dualist pension system, one would expect that their figures for private pension assets should stand somewhere between the individualist and statist pension systems. Japan's data indeed bear this out, but the Korean part appears baffling, partly because this country introduced a new corporate pension scheme in 2005. In addition, as more than two-thirds of workers are covered by the Korean DB corporate pensions, they are actually detrimental to capital accumulation (Phang, Reference Phang, Yang and Klassen2010; Yeh, Reference Yeh, Shi, Mok and Lau2014). Add these factors together, and the size of private pension assets in Korea ranks even lower than that of Taiwan. Finally, in statist arrangements, public pensions have crowded out private pensions, resulting in low private pension assets: 12.06 per cent for Taiwan and 1.2 per cent for China, where this disparity is due to the fact that although Taiwan did not introduce the DC Individual Retirement Account until 2005, it has accumulated a considerable amount of assets during the past decades.

To wrap up the above indicator comparison, Table 6 summarises the key features of the three pension patterns in East Asia. Despite a slight degree of inconsistency in some of the indicator results due to the evolving state of these pension systems, major contours of the three types stand out. In the individualist pension pattern, retirement income security is financialised and individualised through the institutionalisation of provident fund schemes which offer a replacement rate of around 40 per cent, but the role of the state is confined to the provision of means-tested assistance to the poor elderly. By contrast, the statist pattern emphasises the institutionalisation of social insurance pension schemes with high replacement rates, with the market playing a rather minor role in retirement income security. This assumes a significant role on the part of government in the financing and administration of overall pension insurance.

Most conspicuous is the dualist pension pattern of Japan and Korea which prioritises joint collaboration between public and private pensions for retirement income maintenance. Here the citizens’ old-age security hinges on her or his employment status as well as on the corporate pension entitlements. For those marginal workers who are denied access to the above benefits, the government steps in with universal basic pensions for minimum protection. A conceivable cleavage in old-age security emerges between the informal and marginal workers who rely on public basic pensions, and their colleagues in the formal employment sector, especially those in large enterprises, who receive generous corporate pensions on top of the public benefits.
