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...

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...

By how much does an increase in operating effectiveness of a public employment agency (PEA) and a reduction of unemployment benefits reduce unemployment? Using a recent labour market reform in Germany as background, we find that an enhanced effectiveness of the PEA explains about 20% of the...

This paper sheds new light on the effects of the minimum wage on employment from a two-sided theoretical perspective, in which firms' job offer and workers' job acceptance decisions are disentangled. Minimum wages reduce job offer incentives and increase job acceptance incentives. We show that...

There is strong empirical evidence for Cobb-Douglas matching functions. We show in this paper that this widely found relation between matches on the one hand and unemployment and vacancies on the other hand can be the result of different underlying mechanisms. Obviously, it can be generated by...

We theoretically analyse the effects of sick pay and employees' health on collective bargaining, assuming that individuals determine absence optimally. If sick pay is set by the government and not paid for by firms, it induces the trade union to lower wages. This mitigates the positive impact on...

This paper shows that outsourcing of parts of the workforce in unionized firms leads to wage moderation and as long as the share of the outsourced workforce is not too large, this wage-moderation effect on domestic employment outweighs the direct substitution effect so that domestic employment...
