Human resource management practices

Higher inequality reduces capital accumulation and increases the informal economy, which creates additional employment opportunities for low-skilled and deprived people. As a result, informal employment leads to beneficial effects on income distribution by providing sources of income for unemployed and marginalized workers. Despite this positive feedback, informality raises problems for public finances and biases official statistics, reducing the effectiveness of redistributive policies. Policymakers should consider the links between inequality and informality because badly designed informality-reducing policies may increase inequality.

Anti-discrimination policies play an important role in public discussions. However, identifying discriminatory practices in the labor market is not an easy task. Correspondence testing provides a credible way to reveal discrimination in hiring and provide hard facts for policies, and it has provided evidence of discrimination in hiring across almost all continents except Africa. The method involves sending matched pairs of identical job applications to employers posting jobs—the only difference being a characteristic that signals membership to a group.

Workers participating in firm-sponsored training receive higher wages as a result. But given that firms pay the majority of costs for training, shouldn’t they also benefit? Empirical evidence shows that this is in fact the case. Firm-sponsored training leads to higher productivity levels and increased innovation, both of which benefit the firm. Training can also be complementary to, and enhance, other types of firm investment, particularly in physical capital, such as information and communication technology (ICT), and in organizational capital, such as the implementation of high-performance workplace practices.

Economists have for a long time argued that performance-based bonuses raise performance. Indeed, many firms use bonuses tied to individual performance to motivate their employees. However, there has been heated debate among human resources professionals recently, and some firms have moved away from individual performance bonuses toward fixed wages only or collective performance incentive schemes such as profit-sharing or team incentives. The appropriate approach depends on each company's unique situation, and managers need to realize that individual bonus plans are not a panacea to motivate employees.

Employees are more willing to work and put effort in for an employer that genuinely promotes the greater good. Some are also willing to give up part of their compensation to contribute to a social cause they share. Being able to attract a motivated workforce is particularly important for the public sector, where performance is usually more difficult to measure, but this goal remains elusive. Paying people more or underlining the career opportunities (as opposed to the social aspects) associated with public sector jobs is instrumental in attracting a more productive workforce, while a proper selection process may mitigate the negative impact on intrinsic motivation.

When an employer fills a vacancy with one of its own workers (through promotion or horizontal transfer), it forgoes the opportunity to fill the position with a new hire from outside the firm. Although firms use both internal and external hiring methods, they frequently favor insiders. Internal and external hires differ in observable characteristics (such as skill levels), as do the employers making the hiring decisions. Understanding those differences helps employers design and manage hiring policies that are appropriate for their organizations.

Studies from countries with laws against discrimination on the basis of sexual orientation suggest that gay and lesbian employees report more incidents of harassment and are more likely to report experiencing unfair treatment in the labor market than are heterosexual employees. Both gay men and lesbians tend to be less satisfied with their jobs than their heterosexual counterparts. Gay men are found to earn less than comparably skilled and experienced heterosexual men. For lesbians, the patterns are ambiguous: in some countries they have been found to earn less than their heterosexual counterparts, while in others they earn the same or more.

Women's representation on corporate boards, political committees, and other decision-making teams is increasing, this is in part because of legal mandates. Evidence on team dynamics and gender differences in preferences (for example, risk-taking behavior, taste for competition, prosocial behavior) shows how gender composition influences group decision-making and subsequent performance. This works through channels such as investment decisions, internal management, corporate governance, and social responsibility.

A good boss can have a substantial positive effect on the productivity of a typical worker. While much has been written about the peer effects of working with good peers, the effects of working with good bosses appear much more substantial. A good boss can enhance the performance of their employees and can lower the quit rate. This may also be relevant in situations where it is challenging to employ incentive pay structures, such as when quality is difficult to observe. As such, firms should invest sufficiently in the hiring of good bosses with skills that are appropriate to their role.

Arguments for increasing gender diversity on boards of directors by gender quotas range from ensuring equal opportunity to improving firm performance. The introduction of gender quotas in a number of countries has increased female representation on boards. Current research does not justify gender quotas on grounds of economic efficiency. In many countries the number of women in top executive positions is limited, and it is not clear from the evidence that quotas lead to a larger pool of female top executives, who are the main pipeline for boards of directors. Thus, other supplementary policies may be necessary if politicians want to increase the number of women in senior management positions.
