In a situation where tariff reforms are being negotiated between two parties aims to raise its exports and the other aims to raise its welfare, tariff cuts must be in the interest" of at least one party. It is possible for the interests of the two sides to conflict. Conflict is certain" if the...

In contrast to existing work which takes an ex-ante approach and looks for policy prescriptions which yield welfare improvements, we take an ex-post approach. We ask whether there are indicators which show whether welfare has risen or not in the wake of a reform. That is, we look for evidence of...

The market access and welfare effects of Free Trade Areas (FTAs) without Rules of Origin (ROOs) are studied. We consider both the final and intermediate goods markets and their interlinkage. The FTA weakly reduces all tariffs and prices within the FTA. This raises quantity demanded and reduces...

We develop a model to study the behavior of firms in a Free Trade Area with Rules of Origin and the consequences of this behavior on the market equilibrium and outcome. We show that firms will choose to specialize, and that an FTA with strict ROOs on the intermediate good raises imports and...

This paper identifies a new reason for giving preferences to the disadvantaged using a model of contests. There are two forces at work: the effort effect working against giving preferences and the selection effect working for them. When education is costly and easy to obtain (as in the U.S.),...

In this paper we provide some evidence that repeat taking of competitive exams may reduce the impact of background disadvantages on educational outcomes. Using administrative data on the university entrance exam in Turkey we estimate cumulative learning between the first and the nth attempt...

Why do developing countries fail to specialize in products that they (at least potentially) have a comparative advantage in? For example, farmers in land-poor developing countries overwhelmingly produce staples rather than exotic fruits that command high prices. We propose a simple model of...

This paper investigates two main questions: i) What do applicants take into consideration when choosing a high school? ii) To what extent do schools contribute to their students' academic success? To answer these questions, we model students' preferences and derive demand for each school by...

This paper builds a tractable partial equilibrium model in the spirit of Melitz (2003), which incorporates two dimensions of heterogeneity: firms specific productivity shocks and firm-market specific demand shocks. The structural parameters of interest are estimated using only cross-sectional...

This paper surveys recent work on the economic effects, both theoretical and empirical, of Rules of Origin (RoO) in a Free Trade Area (FTA).
