The effectiveness of entrepreneurial leadership (EL) at different levels has been widely recognized by scholars who have carried out substantial exploration; however, the empirical studies on the effectiveness of EL are scattered and their results are mixed. This study aims to organize these findings, advance knowledge about the multilevel effectiveness of EL and clarify the heterogeneity in the relationship between EL and effectiveness outcomes. Based on a systematic review of the extant literature and the construction of an integrated framework, this study examines the influence of EL on effectiveness outcomes at multiple levels and the moderators of this relationship through meta-analysis of 35 empirical studies including 35 independent samples. The results show that EL can improve effectiveness outcomes at different levels of organization, team and individual; cultural context obviously moderates this relationship, whereas the moderating effects of enterprise type and EL measure are all not significant. This study helps to determine the specific association of EL with effectiveness outcomes at different levels, and identify important factors influencing this relationship, which broadens the understanding of leadership effectiveness and provides certain value for enterprises to give full play to the role of EL at all levels.

Mineral deposits of base metals, precious metals, and rare earth elements have been discovered on deep seabeds, and the commercial exploitation of these resources seems poised to begin after faltering for many years. The development of seabed resources could be socially beneficial if all goes well, but the industry faces daunting challenges and uncertainties. Emerging regulations and contracting mechanisms are the principal means for managing these uncertainties. This article recommends a complementary approach: the use of ex ante benefit–cost analysis of proposed seabed mining contracts that incorporates a fundamental uncertainty evaluation. We argue that such an ex ante evaluation will improve the state of information for the decision-making, reducing the risk of regulatory noncompliance or costly contract disputes after seabed mining begins.

Bystander programs contribute to crime prevention by motivating people to intervene in violent situations. Social media allow addressing very specific target groups, and provide valuable information for program evaluation. This paper provides a conceptual framework for conducting benefit–cost analysis of bystander programs and puts a particular focus on the use of social media for program dissemination and data collection. The benefit–cost model treats publicly funded programs as investment projects and calculates the benefit–cost ratio. Program benefit arises from the damages avoided by preventing violent crime. We provide systematic instructions for estimating this benefit. The explained estimation techniques draw on social media data, machine-learning technology, randomized controlled trials and discrete choice experiments. In addition, we introduce a complementary approach with benefits calculated from the public attention generated by the program. To estimate the value of public attention, the approach uses the bid landscaping method, which originates from display advertising. The presented approaches offer the tools to implement a benefit–costs analysis in practice. The growing importance of social media for the dissemination of policy programs requires new evaluation methods. By providing two such methods, this paper contributes to evidence-based decision-making in a growing policy area.

Total cost estimates for crime in the USA are both out-of-date and incomplete. We estimated incidence and costs of personal crimes (both violent and non-violent) and property crimes in 2017. Incidence came from national arrest data, multi-state estimates of police-reported crimes per arrest, national victimization and road crash surveys, and police underreporting studies. We updated and expanded upon published unit costs. Estimated crime costs totaled $2.6 trillion ($620 billion in monetary costs plus quality of life losses valued at $1.95 trillion; 95 % uncertainty interval $2.2–$3.0 trillion). Violent crime accounted for 85 % of costs. Principal contributors to the 10.9 million quality-adjusted life years lost were sexual violence, physical assault/robbery, and child maltreatment. Monetary expenditures caused by criminal victimization represent 3 % of Gross Domestic Product – equivalent to the amount spent on national defense. These estimates exclude the additional costs of preventing and avoiding crime such as enhanced lighting and burglar alarms. They also exclude crimes against businesses and most white-collar and corporate offenses.

The problem of how to evaluate investments in airports has now been studied for over 50 years. This paper analyzes the use of different methods like cost–benefit analysis (CBA), economic impact analysis (EIA), and computable general equilibrium (CGE) models to address the question. It assesses the strength and weaknesses of each method, and it discusses which methods have been used in different countries. The paper argues that the CBA approach and the newer CGE modeling approach address the policy issue well and that both methods are appropriate, although improvements are possible, especially in the newer aspects of evaluation. Furthermore, more data intensive CGE models are able to analyze broader aspects of the evaluation question for which CBA has had difficulty. EIA does not address the problem satisfactorily, and it misleads air transport policy. But this evaluation contrasts sharply with practice. EIA has been extensively used to decide on airport investment. CGE approaches are very promising, though further work is needed for them to reach their full potential. This paper pays particular attention to the relationship between CBA and CGE in airport investment evaluation and also the possible role of wider economic benefits (WEBs) of aviation in evaluation.

The prior literature links cash holdings and returns (Simutin (2010), Palazzo (2012)). Using two signals of aggregate-funding availability, I find that the positive association between cash and returns only exists during constrained funding environments. In unconstrained periods, there is no association between cash and returns. The relation in constrained environments does not appear to be related to capital expenditures, expected return, or distress risk but is more prevalent in firms undertaking research and development (R&D) expenditures. This suggests that the association between cash and returns is more consistent with expanding (or maintaining) future growth opportunities rather than being attributable to differences in capital expenditures or risk.

As industrial-organizational (I-O) psychologists, we have expertise in applying psychological and/or organizational science to the workplace. However, many of us haven’t taken the time to think about how our I-O psychology knowledge can apply to our teaching practice. We walk through some examples of how I-O psychology research can help us be better teachers, and the goal of our paper is to encourage readers to make evidence-based changes to their teaching based on I-O psychology research. We organize our discussion around four areas: training and development, diversity and inclusion, groups and teams, and leadership. Within each, we offer small, medium, and large changes that could be incorporated into classrooms. We hope that readers will be inspired to build on what they do in their classrooms to help students learn about (and be inspired by) our field.

This article explores different approaches to assessing the effectiveness of non-state-based non-judicial grievance mechanisms (NSBGMs) in achieving access to remedy for rightsholders. It queries the approach that has been widely adopted as a result of the United Nations Guiding Principles on Business and Human Rights (UNGPs), which focuses on the procedural aspects of grievance mechanisms. Rather, it stresses the importance of analysing the outcomes of cases for rightsholders. This article tests this hypothesis by undertaking comprehensive empirical research into the complaint mechanism of the Roundtable on Sustainable Palm Oil (RSPO). RSPO is found to perform well when judged according to the UNGPs’ effectiveness criteria. However, it performs poorly when individual cases are assessed to ascertain the outcomes that are achieved for rightsholders. The article therefore argues for the importance of equivalent scrutiny of outcomes in relation to other NSBGMs and provides an approach and accompanying methodology that can be utilized for that purpose.
