We develop a new model of trade in which educational institutions drive comparative advantage and determine the distribution of human capital within and across countries. Our framework exploits a multiplicity of sectors and the continuous support of human capital choices to demonstrate that...

We develop a methodology for studying "large deviations type" questions. Our approach does not require that the large deviations principle holds, and is thus applicable to a larg class of systems. We study a system of queues with exponential servers, which share an arrival stream. Arrivals are...

This paper explores the role of pooled-producer, e.g. private label, trade intermediation in shaping the range and diversity of exports. Direct sales maintain a firm's unique product characteristics (`brand equity'), whereas trade through an intermediary can take two forms — either a...

This paper develops an efficiency theory of contingent trade policies. We model the competition for a domestic market between one domestic and one foreign firm as a pricing game under incomplete information about production costs. The cost distributions are asymmetric because the foreign firm...
