In this paper, we incorporate a positive theory of unemployment insurance into a dynamic overlapping generations model with search-matching frictions and on-the-job learning-by-doing. The model shows that societies populated by identical rational agents, but differing in the initial distribution...

The issue of whether unemployment benefits should increase or decrease over the unemployment spell is analyzed in a tractable model allowing moral hazard, adverse selection and hidden savings. Analytical results show that when the search productivity of the unemployed is constant over the...

This paper presents a tractable dynamic general equilibrium model that can explain cross-country empirical regularities in geographical mobility, unemployment and labor market institutions. Rational agents vote over unemployment insurance (UI), taking the dynamic distortionary effects of...

During the last 10 years, I have spent most of my research time on the economics of climate change. Basically all of it has been done together with my colleagues Per Krusell at IIES and Conny Olovsson at Sveriges Riksbank. Being a truly cross-disciplinary field, the close interaction with many...

This paper claims that technical progress induces early retirement of older workers. It presents a model where human capital is technology specific, so that technical progress erodes some existing human capital. This affects mostly older workers, who have a smaller incentive to learn the new...

This paper presents a model of technical change that combines two lines of research together. It is a task based model, in which automation turns labor tasks to mechanized ones, and there is also a continuous addition of new labor tasks, as in the expanding variety literature. We impose three...
