Introducing default and limited collateral into general equilibrium allows for a theoery of endogenous contracts, ..

In spite of fiat money is useless in a standard Arrow-Debreu model, in this paper we will show that this does not hold true anymore when goods are indivisible. In our setting, although fiat money yields no utility, its price will always be positive and the set of equilibrium allocations changes...

Does the Pareto criterion discriminate among policy choices when the policymaker does not know the correct model of the economy? If the policymaker can specify ex ante preferences for each agent, there will typically be some policy change that improves the welfare of each agent relative to a...

Foreign Direct Investment has become an important source of long-term capital inflows for less developed countries in the last two decades. As documented in previous literature, FDI flows may increase permanently domestic output and represent an important source of technological spillovers for...

In this paper, I develop and test a model of dumping among imperfectly competitive firms in different countries that face stochastic demand. In the theoretical model, I show that foreign firms dump when they face weak demand in their own markets. I then show that an antidumping duty can improve...

McCallum (1995) shows in an influential contribution that, even when controlling for the impact of bilateral distance and region size, borders sharply reduce trade volumes between countries. We use in this paper data on bilateral trade flows between 94 French regions, for 10 industries and 2...

We extend the two-country model by Krugman (1980) to a multi-country set-up and show that the `home-market effect' highlighted with two countries does not readily extend to such a more general setting. In particular, we prove that the most important result, namely the disproportionate causation...

Since the seminal work of Krugman (1979), product variety has played a central role in models of trade and growth. In spite of the general use of love-of-variety models, there has been no systematic study of how the import of new varieties has contributed to national welfare gains in the United...

Some cultural goods, like clothes and films, are consumed socially and are thus characterized by the same consumption network externalities as languages. At the same time, producers of new cultural goods in any one country draw on the stock of ideas generated by previous cultural production in...

Time is money, and distance matters. We model the interaction of these truisms, and show the implications for global specialization and trade: products where timely delivery is important will be produced near the source of final demand, where wages will be higher as a result. In the model,...
