In markets with imperfect information and heterogeneity, the information technology affects the rate at which agents meet, which in turn affects the distribution of production technologies across firms. We show that in models for such markets there are typically multiple equilibria because...

We examine a Bertrand competition game between two intermediaries offering matching services between two sides of a market. Indirect network externalities arise as the probability of finding one's match with a given intermediary increase with the number of agents of the other side who use the...

This Paper examines competition between a dominant network and a challenging network with third-degree or perfect price-discrimination, allowing for arbitrary configurations of network externalities, as well as horizontal and vertical product differentiation. Domination in the coordination game...

How do firms' sales interact across markets? Are foreign and domestic sales complements or substitutes? Using a large French firm-level database that combines balance-sheet and product-destination-specific export information over the period 1995-2001, we study the interconnections between...

Following the rationale for regional redistribution programmes described in the official documents of the European Union, this Paper studies a very simple multi-country model built around two regions: a core and a periphery. Technological spillovers link firms’ productivity in each of the two...

Great attention is now being paid to global imbalances, the growing U.S. current account deficit financed by growing surpluses in the rest of the world. How can the issue be understood in a more historical perspective? We seek a meaningful comparison between the two eras of globalization:...

We consider a neoclassical growth model with endogenous corruption. Corruption and wealth, which are co-determined in equilibrium, are shown to be negatively correlated. Richer countries tend to be less corrupt, and corrupt economies tend to be poorer. This observation gives rise to the...

We analyze how global economic integration of factor markets affects the stability of the macroeconomy, with respect to expectations-driven fluctuations, when countries differ in their labor market institutions. It is shown that, due to the occurrence of equilibrium indeterminacy, liberalization...

Almost all the literature on tax competition in the presence of multinationals (MNCs) and profit shifting ignores trade costs. This Paper studies how economic integration, in terms of reduced trade costs and internationalization of ownership, affects tax competition and equilibrium corporate...

The late 19th century, and more precisely the period between the Irish Famine of 1845-49 and the First World War, was an era of largely free migration. As such, it constitutes a unique policy experiment, in which migration flows reflected underlying economic forces, rather than government...
