We study frictionless matching models in large production economies with and without market imperfections and/or incentive problems. We provide necessary and sufficient distribution-free conditions for monotone matching which depend on the relationship between what we call the segregation payoff...

We study identification in a class of linear rational expectations models. For any given exactly identified model, we provide an algorithm that generates a class of equivalent models that have the same reduced form. We use our algorithm to show that a model proposed by Benhabib and Farmer [1] is...

Europe is reorganizing its international value chain. I document these changes in Europe’s international organization of production with new survey data of Austrian and German firms investing in Eastern Europe. I show estimates of the share of intra-firm trade between Austria and Germany on...

Two key issues are examined in an integrated framework: the emergence of global imbalances and the precautionary motive for accumulating reserves. Standard models of general equilibrium would predict modest current account surpluses in the emerging markets if they face higher risk than the US...

Progress in the application of matching models to environments in which the utility between matching partners is not fully transferable has been hindered by a lack of characterization results analogous to those that are known for transferable utility. We present sufficient conditions for...

It has been argued that concave models exhibit less ‘endogeneity of growth’ than models with increasing returns to scale. Here we study a simple model of factor saving technological improvement in a concave framework. Capital can be used either to reproduce itself, or, at some additional...

We analyse a general equilibrium model in which there is both adverse selection of and moral hazard by banks. The regulator has several tools at their disposal to combat these problems. They can audit banks to learn their type prior to giving them a license, they can audit them ex post to learn...

The aim of this paper is to explore the structure of cities as a function of labor differentiation, gains to trade, a fixed cost for constructing the transportation network, a variable cost of commodity transport, and the commuting costs of consumers. Firms use different types of labor to...

This Paper develops a continuous-time two-sector model to study the economic effects of an import quota during the period of time over which it is imposed. One of the sectors is protected by a quota, which in our set-up manifests itself as an integral constraint on the flow of imports of the...
