Many social networks have the following properties: (i) a short average distancebetween any two individuals; (ii) a high clustering coe±cient; (iii) segregation pat-terns; the presence of (iv) brokers and (v) hubs. (i) and (ii) de¯ne a small worldnetwork. This paper develops a strategic...

This paper discusses the place of oligopoly in international trade theory, and ar-gues that it is unsatisfactory to ignore …rms altogether, as in perfectly competitivemodels, or to view large …firms as more productive clones of small ones, as in monop-olistically competitive models. Doing...

This paper examines monetary policy in a currency union whose member countries exhibitheterogeneous rates of limited asset markets participation (LAMP). As a result risksharing among member countries is imperfect and the monetary transmission mechanismcan dier across countries. In the limit the...

This paper presents simple conditions for monopoly third-degree price discrimination to have negative or positive e¤ectson aggregate consumer surplus. Consumer surplus is often re-duced by discrimination, for example when total welfare (con-sumer surplus and pro…ts) falls. Surplus increases...

We present a gravity model that accounts for multilateral resistance, firm heterogeneity and country-selectioninto trade, while accommodating asymmetries in trade flows. A new equation for the proportion of exporting…firms takes a gravity form: the extensive margin is also accected by...

In this paper we develop a dynamic structural life-cycle model of labor supplybehavior which fully accounts for the eects of income tax and transfers on la-bor supply incentives. Additionally, the model recognizes the demand side drivenrationing risk that might prevent individuals from realizing...
