The relationship between market integration and the degree of specialization plays a key role in many areas of economics. In contrast to previous studies, we illustrate that globalization does not necessarily lead to specialization. The analysis is conducted in an extended Dixit-Stiglitz- Ethier...

This study analyzes the impact of international trade on the diffusion of flexible manufacturing in a general equilibrium framework. Suppliers produce a flexible base product that can be adapted to the specific input requirements of a continuum of downstream industries. The vertical structure is...

This paper models tax competition for mobile firms that are differentiated by the amount of labor needed to cover fixed costs. Because tax competition affects the distribution of firms, it affects both relative equilibrium wages across countries and equilibrium prices. These in turn influence...

We set up a general equilibrium model with heterogeneous firms to study the interaction between wage bargaining and foreign direct investment. Thereby, we highlight the incentives of firms to invest abroad in order to improve their bargaining position vis--vis local unions and we show how...

The popular Dixit-Stiglitz-Ethier framework proposes that globalization increases the menu of intermediate goods available to downstream firms and that gains from specialization raise welfare unambiguously. This study shows that both results depend critically on the assumption that demand...

This paper models tax competition for mobile firms that are differentiated by the amount of labor needed to cover fixed costs. Because tax competition affects the distribution of firms, it affects both relative equilibrium wages across countries and equilibrium prices. These in turn influence...

We present a new model of multi-product firms (MPFs) and flexible manufacturing and explore its implications in partial and general equilibrium. International trade integration affects the scale and scope of MPFs through a competition effect and a demand effect. We demonstrate how MPFs adjust in...

Multinational enterprises are able to improve their disagreement profits by setting up foreign production facilities, with adverse consequences for negotiated wages and union utilities. In this paper, we take a new angle at this issue and analyze whether unions can improve their situation by...

We develop a new model of multi-product firms which invest to improve the perceived quality of both their individual products and their brand. Because of flexible manufacturing, products closer to firms' core competence have lower costs, so firms produce more of them, and also have higher...
