This volume was prepared by Sebastian Benz while he was working at the Ifo Institute. It was completed in December 2013 and accepted as a doctoral thesis by the Department of Economics at the University of Munich. It includes five self-contained chapters. All chapters discuss different...

A two country model of trade between a flexiwage and a minimum wage economy or two mmjmum wage economies is developed. The main novelty is that there are three factors of production: capital, skilled and unskilled labour. This unlocks the terms of trade. Unskilled labour is subject to the same...

Rising inequality in the relative wages of skilled and unskilled labor is often attributed to skill-biased technological progress. This paper presents a model in which the adoption of skill-biased or "unskilled-biased" technologies is endogenous. Conventional wisdom states that an increase in...

This paper studies the employment effects of technological change when benefits are endogenous. If the (i) level of welfare aid depends on the general income level in the economy and (ii) wages for unskilled workers cannot fall below the level of welfare aid, there is a link between the wage for...

We analyze the employment effects of immigration within a model that accounts for several stylized facts of the German labor market. The co-existence of positive wage spans and unemployment is explained by wage rigidities that are simultaneously caused by effciency-wage setting and minimum...

An economy's production set is the collection of all net output vectors that the economy is capable of producing with a given technology and fixed quantities of primary factors of production. The boundary of this set is called the production possibility frontier or PPF. We show that, if the...

We estimate the extent of factor bias in technical changes consistent with observed changes in skill premia. To control for the effects of expanded trade on wages we use a structural model with multiple regions and comparative static analysis. Two alternative biased technical-change stories...

The US labour market is characterized by a high skill wage mark-up and low unemployment, while the German labour market has a low skill wage mark-up and a high, mainly unskilled unemployment rate. This paper adds an innovative labour supply explanation to the discussion how these distinct labour...

This paper provides a labour supply explanation to the observation that in Germany employment changes are asymmetric during the business cycle. Employment increases are slower, because the reservation wage of workers increases in times of job uncertainty. Workers are afraid in those periods of...

Skill-Biased Technical Change is one of the most prominent explanations for the rise in wage inequality in the United States over the last decades. However, the explanation is challenged for several reasons. In this paper, I propose an alternative type of technical change, where new technologies...
