Evidence-based policy making

Ireland was hit particularly hard by the global financial crisis, with severe impacts on the labor market. Between 2007 and 2013, the unemployment rate increased dramatically, from 5% to 15.5%, and the labor force participation rate declined by almost five percentage points between 2007 and 2012. Outward migration re-emerged as a safety valve for the Irish economy, helping to moderate impacts on unemployment via a reduction in overall labor supply. As the crisis deepened, long-term unemployment escalated. However, since 2013, there is clear evidence of a recovery in the labor market with unemployment, both overall and long-term, dropping rapidly.

South Korea has boasted one of the world's most successful economies since the end of World War II. The South Korean labor market has recovered quickly from the depths of the Asian crisis in 1998, and has since remained surprisingly sound and stable. The unemployment rate has remained relatively low, and average real earnings have steadily increased. The South Korean labor market was resilient in the wake of the global financial crisis. However, there are issues that require attention, including high earnings inequality, an aging labor force, increasing part-time jobs, and rising youth unemployment rates.

Economic growth requires factor reallocation across firms and continuous replacement of technologies. Labor market institutions influence economic dynamism by their impact on the supply of a key factor, skilled workers to new and expanding firms, and the shedding of workers from declining and failing firms. Growth-favoring labor market institutions include portable pension plans and other job tenure rights, health insurance untied to the current employer, individualized wage-setting, and public income insurance systems that encourage mobility and risk-taking in the labor market.

Many industrial countries are pursuing so-called green energy policies, which typically imply the replacement of conventional fossil fuel power plants with renewable sources. Such a policy shift may affect employment in different ways. On the one hand, it could create new and additional “green jobs” in the renewables sector; on the other hand, it could crowd out employment in other sectors. An additional consideration is the potential increase in energy prices, which has the potential to stifle labor demand in energy-intensive sectors and reduce the purchasing power of private households.

Over recent decades, Western countries have admitted many immigrants from non-traditional regions (e.g. Philippines, India, China), which has coincided with poor economic integration. Language proficiency is an important determinant of economic integration; in addition to being a component of human capital, it plays a key role in facilitating the transmission of other components of human capital. Examining the strengths and weaknesses of objective and subjective measures of language proficiency is crucial for good integration policy, as is understanding the relationship between these measures and earnings, a key indicator of economic integration.

In the context of growing worldwide inequality, it is important to know what happens when the demand for low-skilled workers changes. Because natural resource shocks are global in nature, but have highly localized impacts on labor prospects in resource extraction areas, they offer a unique opportunity to evaluate low-skilled men's behavior when faced with extreme variations in local labor market conditions. This situation can be utilized to evaluate a broad range of outcomes, from education and income, to marital and fertility status, to voting behavior.

The EU's largest economy, Germany, has managed to find an effective and unique combination of flexibility and rigidity in its labor market. Institutions that typically characterize rigid labor markets are effectively balanced by flexibility instruments. Important developments since 2000 include steadily decreasing unemployment rates (since 2005), increasing participation rates, and (since 2011) moderately increasing labor compensation. The German labor market was remarkably robust to the impacts of the Great Recession, thus providing a useful case study for other developed countries.

Teacher effectiveness is the most important component of the education process within schools for pupil attainment. One estimate suggests that, in the US, replacing the least effective 8% of teachers with average teachers has a present value of $100 trillion. Researchers have a reasonable understanding of how to measure teacher effectiveness; but the next step, understanding the best ways to raise it, is where the research frontier now lies. Two areas in particular appear to hold the greatest promise: reforming hiring practices and contracts, and reforming teacher training and development.
