We develop a general equilibrium model of international trade with heterogeneous firms that accounts for productivity spillovers transmitted by foreign exporters. Everything else equal, stronger spillovers increase welfare. We embed the model framework into a trade policy scenario where...

We study a general equilibrium model of international trade with heterogeneous fi rms, where countries can strategically invest in technology. The countries’ motive is to improve fi rms’ productivity, leading to a competitive advantage in international trade. We are interested in how trade...

We study a general equilibrium model of international trade with heterogeneous firms, where countries can strategically invest in technology. The countries' motive is to improve firms' productivity, leading to a competitive advantage in international trade. We are interested in how trade...

We develop a general equilibrium model with heterogeneous firms à la Melitz (2003), where both the government and firms can invest into R&D to improve the country's technological potential. A higher technological potential raises the average productivity of firms, thus implying lower consumer...

This paper examines the growth effects of an increase of capital income taxes with additional revenue being devoted to cut wage-related social security contributions to reduce unemployment. The analysis is carried out in an overlapping generations model with endogenous growth, unemployment and a...

Previous experimental investigations have shown that expectations are not perfectly rational due to bias. Traditional adaptive models, however, in many cases do not perfectly describe the formation of expectations either. This paper makes two contributions to the experimental literature on the...

We propose a new explanation for differences and changes in labor supply by gender and marital status, and in particular for the increase in married women’s labor supply over time.We argue that this increase as well as the relative constancy of other groups’ hours are optimal reactions to...

In Germany we observe a decline in regular employment and an increase in atypical forms of employment. Especially marginal part-time employment which is characterized by lower tax rates and lower social security contributions increased substantially after a reform in 2003 made this type of...

A number of recent empirical studies document significant effects of in-patient care quality indicators on the choice of hospital. These studies use either objective quality indicators based on quantitative figures, or if subjective reputation scores are used, scores based on the opinion of...
