This paper proposes a new mechanism linking trade and wage inequality in developing countries - the quality-upgrading mechanism - and investigates its empirical implications in panel data on Mexican manufacturing plants. In a model with heterogeneous plants and quality-differentiated goods, only...

This paper examines how schools choose class size and how households sort in response to thosechoices. Focusing on the highly liberalized Chilean education market, we develop a model inwhich schools are heterogeneous in an underlying productivity parameter, class size is a componentof school...

This paper uses uniquely rich and representative data on the unit values of outputs (products)and inputs of Colombian manufacturing plants to draw inferences about the extent of quality differentiation at the plant level. We extend the Melitz (2003) framework to include heterogeneity of inputs...

Disparities in health outcomes between white and minority Americans are a significant and well documented challenge in improving equity in health care. Two frequently cited explanations are discrimination in treatment - doctors treating minority patients differently, and unequal access to care -...

This paper examines how schools choose class size and how households sort in response to those choices. Focusing on the highly liberalized Chilean education market, we develop a model in which schools are heterogeneous in an underlying productivity parameter, class size is a component of school...

The authors draw on an internal attitude survey conducted yearly from 1996 to 2000 in the freight-handling terminals of a unionized trucking firm to investigate the effect of local labor market conditions on employee wage-fairness perceptions. Their research design exploits the fact that local...
