This paper studies competition in regulation and commodity taxation between trading countries. We present a general equilibrium model in which destination based consumption taxes finance public goods, while regulation of entry determines the number of firms in the markets. We find (i) no...

This paper discusses the role of the Clean DevelopmentMechanisms (CDM) on the market for carbon quotas and countries' commitments to reduce their carbon emission levels. We show that the CDM contributes to an efficient funding of clean technology investments in least developed countries. How-...

In this paper we study the role of private debt financing in disciplining a state owned firm operating for a government that incurs a cost of public financing. We show that debt contracts allow the government to avoid socially costly subsidies by letting unprofitable state- owned firms default....

The present paper studies the effect of the choice of product quality on trade and location of firms. We build a quality-augmented model where consumers have preferences for the quality of a set of differentiated varieties. Firms do not only develop and sell manufacturing varieties in a...

In this paper we study how the trade costs and the intensity of competition can explain the existence of bilateral trade, unilateral trade and no trade within an industry. We show as trade costs decrease from very high to very low values, the global economy moves from autarky to a regime of...

Empirical research on strategic alliances has focused on the idea that alliance partners are selected on the basis of social capital considerations. In this paper we emphasize instead the role of complementary knowledge stocks (broadly defined) in partner selection, arguing not only that...

In the Dixit-Stiglitz model of monopolistic competition, entry of firms is socially too small. Other authors have shown that excess entry is also a possibility with other preferences for diversity. We show that workers' rents also contribute to explain excess entry through a general equilibrium...

Social interactions are at the essence of societies and explain the gathering of in- dividuals in villages, agglomerations, or cities. We study the emergence of multiple agglomerations as resulting from the interplay between spatial interaction external- ities and competition in the land market....

Economic regions, such as urban agglomerations, face external demand and price shocks that produce income risk. Workers in large and diversified agglomerations may benefit from reduced wage volatility, while firms may outsource the production of intermediate goods and realize benefits from...

This paper considers a simple stochastic model of international trade with three countries. Two of the tree countries are in an economic union. Comparisons are made between equilibrium welfare for these two countries under fixed and flexible exchange rate regimes. Within the model it is shown...
