In this paper six authors propose guidelines for German labor market policy, to overcome current discouragement and lead to a new balance of social security and individual competetiveness. Crucial aspects in this regard should be a reformed tax system based on excise instead of income taxes, and...

This paper studies the social desirability of agglomeration and the efficiency arguments for policy intervention in a simple, analytically solvable 'new economic geography' model with two trade integrating regions. The location pattern emerging as market equilibrium is bubbleshapedʺ, i.e. it...

This paper explores the quantitative consequences of transatlantic trade liberalization envisioned in a Transatlantic Trade and Investment Partnership (TTIP) between the United States and the European Union. Our key innovation is to develop a new quantitative spatial trade model and to use an...

The division of labor between and within countries is driven by two fundamental forces, comparative advantage and increasing returns. We set up a simple Ricardian model with a Marshallian input sharing mechanism to study their interplay. The key insight that emerges is that the interaction...

The core-periphery model by Krugman (1991) has two 'dramatic' implications: catastrophic agglomeration and locational hysteresis. We study this seminal model with CES instead of Cobb-Douglas upper tier preferences. This small generalization suffices to change these stark implications. For a wide...
