Evidence-based policy making

Risk aversion is an important factor in many settings, including individual decisions about investment or occupational choice, and government choices about policies affecting environmental, industrial, or health risks. Risk preferences are measured using surveys or incentivized games with real consequences. Reviewing the different approaches to measuring individual risk aversion shows that the best approach will depend on the question being asked and the study's target population. In particular, economists’ gold standard of incentivized games may not be superior to surveys in all settings.

Immigrants are widely perceived to be highly entrepreneurial, contributing to economic growth and innovation, and self-employment is often viewed as a means of enhancing labor market integration and success among immigrants. Accordingly, many countries have established special visas and entry requirements to attract immigrant entrepreneurs. Research supports some of these stances, but expectations may be too high. There is no strong evidence that self-employment is an effective tool of upward economic mobility among low-skilled immigrants. More broadly prioritizing high-skilled immigrants may prove to be more successful than focusing on entrepreneurship.

Compliance with minimum wage laws and non-wage conditions of employment often depends on labor market specific factors. In developing countries, many workers still earn less than the legal minimum and lack access to mandated non-wage benefits. Enforcement has not kept up with regulation growth and compliance has not been measured from a multidimensional perspective. Such an approach would help to understand the impact of institutional variables and country-specific approaches on the level of labor law violation. The difference between de facto and de jure regulation remains particularly pertinent in countries where compliance is low.

In recent decades, the number of university students worldwide who have received some part of their education abroad has been rising rapidly. Despite the popularity of international student exchange programs, however, debate continues over what students actually gain from this experience. A major advantage claimed for study abroad programs is that they can enhance employability by providing graduates with the skills and experience employers look for. These programs are also expected to increase the probability that graduates will work abroad, and so may especially benefit students willing to pursue an international career. However, most of the evidence is qualitative and based on small samples.
