Economic conditions such as convexity, homogeneity, homotheticity, and monotonicity are all important assumptions or consequences of assumptions of economic functionals to be estimated. Recent research has seen a renewed interest in imposing constraints in nonparametric regression. We survey the...

This paper defines informal sector employment and decomposes the difference in earnings distributions between formal and informal sector employees in Tajikistan for 2007. Using the quantile regression decomposition technique proposed by Machado and Mata (2005), we find a significant informal...

This paper examines the impact of the legal status of overseas migrants on their wages upon return to the home country. Using unique data from Egypt, which allows us to distinguish between return migrants according to their type of international migration, documented versus undocumented, we...

How will the emergence of ChatGPT and other forms of artificial intelligence (AI) affect the skill premium? To address this question, we propose a nested constant elasticity of substitution production function that distinguishes among three types of capital: traditional physical capital...

This paper applies semiparametric regression models to shed light on the relationship between body weight and labor market outcomes in Germany. We find conclusive evidence that these relationships are poorly described by linear or quadratic OLS specifications, which have been the main approaches...

We study the role of firm productivity in explaining earnings disparities between immigrants and natives using population-wide matched employer-employee data from Sweden. We find substantial earnings returns to working in firms with higher persistent productivity, with greater gains for...

In many OECD countries, low productivity growth has coincided with rising inequality. Widening wage and productivity gaps between firms may have contributed to both developments. This paper uses a new harmonised cross-country linked employer-employee dataset for 14 OECD countries to analyse the...

Using Local Labour Systems (LLSs) data, this work aims at assessing the effects of sectoral shifts and industry specialization patterns on regional unemployment in Italy over the years 2004-2008, when huge worker reallocation caused by changes in the international division of labour occurred....

This paper investigates how students' collegiate athletic participation affects their subsequent labor market success. It uses newly developed distributional tests to establish that the wage distribution of former college athletes is significantly different from non-athletes and that athletic...

This paper is devoted to the study of diversification and specialization influence on one of the main indicators of Russian labour market, the unemployment growth. The purpose of the work is to find out which effects dominate in the Russian regions, Marshallian or Jacobs, and whether this...
