We show that a minimum wage introduced in the presence of asymmetric information about worker productivities will lead to lower unemployment levels than predicted by the standard labour market model with heterogeneous labour and symmetric information. -- minimum wages ; unemployment ; asymmetric...

Students' choices in education can only be based on expected outcomes. Econometric models that infer expectations based on ex post outcomes impose a rational structure of expectations on school performance and post-graduation earnings. Direct surveys suggest much ignorance and fuzziness. We use...

The canonical supply-demand model of the wage returns to skill has been extremely influential; however, it has faced several important challenges. Several studies show that the standard approach sometimes produces theoretically wrong-signed elasticities of substitution, yields counterintuitive...

Anthropogenic greenhouse gas emissions are changing the energy balance of our planet. Various climatic feedbacks make the resulting warming over the next decades and centuries highly uncertain. We quantify how this uncertainty changes the optimal carbon tax in a stochastic dynamic programming...

In this article we estimate the long-run aggregate elasticity of substitution between skilled and unskilled workers. This is an important parameter as it allows us to compute the skill biased technological progress (SBTP) from the evolution of relative wages. However, it is hard to estimate...

We analyze self-selection and sorting of emigrants from Finland, using full-population administrative data from Statistics Finland. We analyze emigration events lasting at least five years and decompose migrant self-selection into education, occupation, and unobserved abilities. Our analysis...

I take advantage of a sharp discontinuity in the probability of admission to an elite university at the admission score threshold, to estimate causal returns to college education quality. I use a newly constructed dataset, which combines individual administrative records about high school,...
