Human resource management practices

Environmental regulations are typically considered to be a drag on the economy. However, improved environmental quality may actually enhance productivity by creating a healthier workforce. Evidence suggests that improvements in air quality lead to improvements in worker productivity at the micro level across a range of sectors, including agriculture, manufacturing, and the service sectors, as well as at more aggregate macro levels. These effects also arise at levels of air quality that are below pollution thresholds in countries with the highest levels of environmental regulation. The findings suggest a new approach for understanding the consequences of environmental regulations.

Alternative dispute resolution procedures such as arbitration and mediation are the most common methods for resolving wage, contract, and grievance disputes, but they lead to varying levels of success and acceptability of the outcome depending on their design. Some innovative procedures, not yet implemented in the real world, are predicted to improve on existing procedures in some ways. Controlled tests of several procedures show that the simple addition of a nonbinding stage prior to binding dispute resolution can produce the best results in terms of cost (monetary and “uncertainty” costs) and acceptability.

The use of anonymous job applications (or blind recruitment) to combat hiring discrimination is gaining attention and interest. Results from field experiments and pilot projects in European countries (France, Germany, the Netherlands, Finland and Sweden are considered here), Canada, and Australia shed light on their potential to reduce some of the discriminatory barriers to hiring for minority and other disadvantaged groups. But although this approach can achieve its primary aims, there are also important cautions to consider.

Charity rating agencies often focus on overhead cost ratios in evaluating charities, and donors appear to be sensitive to these measures when deciding where to donate. Yet, there appears to be a tenuous connection between this widely-used metric and a charity’s effectiveness. There is evidence that a focus on overhead costs leads charities to underinvest in important functions, especially skilled workers. To evaluate policies that regulate overhead costs, it is necessary to examine whether donors care about overhead costs, whether they are good measures of charity effectiveness, and what effects a focus on overhead costs has on charities.

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.

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.

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.

Managers are supervising more and more workers, and firms are getting flatter. However, not all firms have been keen on increasing the number of subordinates that their bosses manage (referred to as the “span of control” in human resource management), contending that there are limits to leveraging managerial ability. The diversity of firms’ organizational structure suggests that no universal rule can be applied. Identifying the factors behind the choice of firms’ internal organization is crucial and will help firms properly design their hierarchy and efficiently allocate scarce managerial resources within the organization.

Can a company attract a different type of employee by changing its compensation scheme? Is it sufficient to pay more to increase employees’ motivation? Should a firm provide evaluation feedback to employees based on their absolute or their relative performance? Laboratory experiments can help address these questions by identifying the causal impact of variations in personnel policy on employees’ productivity and mobility. Although they are collected in an artificial environment, the qualitative external validity of findings from the lab is now well recognized.

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.
