Demography

For decades, pension systems were based on the rising revenue generated by an expanding population (the so-called demographic dividend). As changes in fertility and longevity created new population structures, however, the dividend disappeared, but pension systems failed to adapt. They are kept solvent by increasing redistributions from the shrinking working-age population to retirees. A simple and transparent structure and individualization of pension system participation are the key preconditions for an intergenerationally just old-age security system.

The importance of benefit portability is increasing in line with the growing number of migrants wishing to bring acquired social rights from their host country back to their country of residence. Failing to enable such portability risks impeding international labor mobility or jeopardizing individuals’ ability to manage risk across their life cycle. Various instruments may establish portability. But which instrument works best and under what circumstances is not yet well-explored.

Discrimination is a complex, multi-factor phenomenon. Evidence shows widespread discrimination on various grounds, including ethnic origin, sexual orientation, gender identity, religion or beliefs, disability, being over 55 years old, or being a woman. Combating discrimination requires combining the strengths of a range of anti-discrimination policies while also addressing their weaknesses. In particular, policymakers should thoroughly address prejudice (taste-based discrimination), stereotypes (statistical discrimination), cognitive biases, and attention-based discrimination.

In Germany, young people are no worse off than adults in the labor market, while in southern and eastern European countries, they fare three to four times worse. In Anglo-Saxon countries, both youth and adults fare better than elsewhere, but their unemployment rates fluctuate more over the business cycle. The arrangements developed in each country to help young people gain work experience explain the striking differences in their outcomes. A better understanding of what drives these differences in labor market performance of young workers is essential for policies to be effective

Countries are not perfectly integrated market areas. Even if institutional differences are much smaller within than between countries, there are persistent local cultural differences. These differences act as barriers that reduce economic exchange: bilateral migration, trade, and knowledge diffusion flows are smaller, and individuals discriminate against unfamiliar dialects. They also act as natural limits to the degree of integration of a labor market, and they cannot (and perhaps should not) be easily affected by policy. Local dialects, shaped over centuries, provide a unique opportunity to measure these barriers.

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.

As the third largest economy in the world and a precursor of global trends in population aging, Japan’s recent experiences provide important lessons regarding how demographic shifts affect the labor market and individuals’ economic well-being. On the whole, the labor market has shown a remarkable stability during the recent financial crisis, despite decades of economic stagnation and sluggish real wage growth. Rapid population aging, however, has brought substantial changes to individuals in the labor market, most notably among women, by augmenting labor demand in the healthcare services industry.

Research finds that hot weather causes a fall in birth rates nine months later. Evidence suggests that this decline in births is due to hot weather harming reproductive health around the time of conception. Birth rates only partially rebound after the initial decline. Moreover, the rebound shifts births toward summer months, harming infant health by increasing third trimester exposure to hot weather. Worse infant health raises health care costs in the short term as well as reducing labor productivity in the longer term, possibly due to lasting physiological harm from the early life injury.

As migration rates increase across the world, the choice of whether to retire in the host or home country is becoming a key decision for up to 15% of the world’s population, and this proportion is growing rapidly. Large waves of immigrants who re-settled in the second half of the 20th century are now beginning to retire. Although immigrants’ location choice at retirement is an area that has barely been studied, this decision has crucial implications for health care and social protection expenditures, both in host and origin countries.

The Great Recession that began in 2008–2009 dramatically increased youth unemployment. But did it have long-lasting, adverse effects on the careers of youths? Are cohorts that graduate during a recession doomed to fall permanently behind those that graduate at other times? Are the impacts different for low- and high-educated individuals? If recessions impose penalties that persist over time, then more government outlays are justified to stabilize economic activity. Scientific evidence from a variety of countries shows that rigid labor markets can reinforce the persistence of these setbacks, which has important policy implications.
