Why are empirically observed tariffs so much lower than theoretically calculated Nash-equilibrium tariffs? We argue that this gap can be narrowed by using a dynamic model instead of a static model. This approach has two advantages. (i) It allows us to take account of the transitional process...

In this paper, we present a standard quality ladders endogenous growth model with one significant new assumption, that it takes time for firms to learn how to export. We show that this model without Melitz-type assumptions can account for all the evidence that the Melitz (2003) model was...

This paper develops an efficiency theory of contingent trade policies. We model the competition for a domestic market between one domestic and one foreign firm as a pricing game under incomplete information about production costs. The cost distributions are asymmetric because the foreign firm...

We develop a general-equilibrium model to capture key features of the retailing and of the manufacturing industry in order to understand how these two industries interact and how labor is allocated between them. We show that the observed shift in employment from manufacturing to retailing, the...

In the last decades, foreign direct investment (FDI) has increased strongly among industrialised countries. U.S. companies were the first to set up foreign affiliates followed later by companies from smaller industrialised countries. This paper develops a general equilibrium model of...

Network-effects may lead to imperfect competition and may therefore make a Strategie trade policy attractive for a country exporting network goods. I analyze the implications of Strategie trade policy in a model of horizontal produetdifferentiation with network effects. Within this framework,...

This study analytically shows that a VER serves as an institution to protect incumbent firms of an exporting country. A VER is an entry barrier in the export market. It favours the concentration of industry, and allows established firms to better exploit economies of scale by producing output at...

Trade, foreign direct investment and the existence of multinational enterprises are often analyzed in separate model, which are frequently based on mutually exclusive assumptions. The paper integrates several features of international economic exchange into one general equilibrium model. This...

This paper presents an economic geography model to show the spatial effects of economic integration. While other authors mainly focused on the explanation of cumulative causation effects that lead to complete concentration or absolutely equal dispersion of industries, this paper explains why...
