In this paper, we show the causal influence of the launch of generative AI in the form of ChatGPT on the search behavior of young people for apprenticeship vacancies. There is a strong and long-lasting decline in the intensity of searches for vacancies, which suggests great uncertainty among the...

How exposed is the labour market to ever-advancing AI capabilities, to what extent does this substitute human labour, and how will it affect inequality? We address these questions in a simulation of 711 US occupations classified by the importance and level of cognitive skills. We base our...

We study the labour market impact of a major shock of return migration, following the end of the Portuguese Colonial War in 1974. The retornados influx is unique because of its size (half a million people in a country of nine million), and similarity with the native population (almost 80% of the...

This paper characterizes the optimal redistributive tax schedule in a matching unemployment framework where (voluntary) nonparticipation and (involuntary) unemployment are endogenous. The optimal employment tax rate is given by an inverse employment elasticity rule. This rule depends on the...

Denmark has accepted refugees from a large variety of countries and for more than four decades. Denmark has also frequently changed policies and regulations concerning integration programs, transfer payments, and conditions for permanent residency. Such policy variation in conjunction with...

While economic theory suggests substitutability between labor and capital, little evidence exists regarding the causal effect of labor supply on inventing labor-saving technologies. We analyze the impact of exogenous changes in regional labor supply on automation innovation by exploiting an...

This paper characterizes long-run and short-run optimal fiscal policy in the labor selection framework. In a calibrated non-Ramsey decentralized equilibrium, labor market volatility is inefficient. Keeping fixed the structural parameters, the Ramsey government achieves efficient labor market...

The advent of the internet, and more recently of artificial intelligence (AI), has challenged academic and other institutions to ensure ethical practices and reward/promote true merit. The borderless and relatively anonymous nature of the internet creates policing challenges, leading to the...

We derive a general optimal income tax formula when individuals respond along both the intensive and extensive margins and when income effects can prevail. Individuals are heterogeneous across two dimensions: their skill and their disutility of participation. Preferences over consumption and...
