Brain drain refers to the selective emigration of highly educated people, who often have stronger incentives to migrate and face fewer barriers. At first glance, this seems to be an adverse situation: losing doctors, engineers or teachers could hinder development. However, migration can also be beneficial by spurring investment in skills, fueling remittances, fostering innovation, business links, and transfers of knowledge and norms. The net impact depends on the skills involved and the context, creating an opportunity for policies that transform emigration into a driver of development.

The Portuguese labour market has stabilised after the 2010–2013 sovereign debt crisis, which pushed unemployment to a historic 18.5%. By 2025, the rate of unemployment has exhibited low-record levels reaching 5.9%. Long-term unemployment has declined, and the female employment rate reached historical values. Yet, several structural imbalances persist. Productivity levels remain low compared to European peers, and wages continue to struggle to keep pace with the cost of living.

How do minimum wage policies interact with labour tax evasion? In many transition economies, two features stand out: a large spike in the wage distribution at the minimum wage and widespread use of “envelope wages”—undeclared cash paid in addition to official earnings. This spike can be explained by the over-representation of tax-evading employers among minimum wage payers. In such a context, raising the minimum wage may serve as an enforcement tool by compelling evading firms to convert part of the undeclared pay into formal wages in order to comply with the legal minimum.

While Mexico has improved the education of its labor force, maintained a stable macroeconomic environment, and been friendly to international trade, its labor market still faces many challenges. In particular, Mexico has difficulty creating high-paying jobs: the share of informal employment has remained stagnant for the last 20 years, and, by 2025, remains above 50%. These problems are particularly poignant in southern Mexico.

It is common practice to incorporate additional covariates in empirical economics. In the context of regression discontinuity (RD) designs, covariate adjustment plays multiple roles, making it essential to understand its impact on analysis and conclusions. Typically implemented via local least squares regressions, covariate adjustment can serve three main distinct purposes: (i) improving the efficiency of RD average causal effect estimators, (ii) learning about heterogeneous RD policy effects, and (iii) changing the RD parameter of interest.

The Netherlands has long been an example of a highly and centrally institutionalized labor market paying considerable attention to equity concerns. Fracturing of the labor force by the rapid demise of the single-earner model and accelerating immigration, falling union density, and reductions in welfare state provisions have shrunk labor’s market power centrally and decentrally. Wages lagged far behind productivity growth, job security strongly declined and wage inequality increased. This comes to the fore with a lack of offensive union power when after 2016 labor demand accelerated and the economy and employment quickly reached new heights after the pandemic crisis.

The Indian economy entered an ongoing process of trade liberalization, domestic deregulation, and privatization of public sector units in 1991. Since then, per capita output has increased significantly, while the overall unemployment rate has remained moderate. However, labor force participation rates fell sharply, though recovering for women since 2020. Youth unemployment remains high, an overwhelming proportion of the labor force continues to work in the informal sector, labor movement out of agriculture is slow, and there is little evidence of a sustained rise in wages for either unskilled rural or factory workers.

In the first two decades of the 2000s, Turkey has relied on structural change from traditional to modern sectors on the one hand and educational compositional change on the other hand to create formal employment in the modern sector. In 2000 the share of formally employed salaried employees in total employment was less than 40% for men and 30% for women. By 2021, this ration converged to 60% for men and women. Formal employment has increased for both men and women and the gender gap in formal employment declined substantially until 2020. However, relying on structural change and education to improve job quality has likely run its course. Since Covid-19, time-related underemployment has increased from virtually zero to 10% of the labor force and wages are stagnating if not declining.
