This paper examines the relationship between the destination of exports and the input prices paid by firms, using detailed customs and firm-product-level data from Portugal. Both ordinary least squares regressions and an instrumental-variable strategy using exchange-rate movements (interacted...

Migration facilitates the flow of information between countries, thereby reducing informational frictions that potentially hamper cross-country financial flows. Using a gravity model, migration is found to be highly correlated with financial flows from the migrant's host country to her home...

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...

Este artículo presenta resultados nuevos sobre los precios de los insumos pagados por las plantas manufactureras en Colombia, utilizando información de la Encuesta Anual Manufacturera (EAM). Los resultados son los siguientes: (1) Los importadores son más exitosos que los no importadores, en...

Drawing on uncommonly rich and representative data from the Colombian manufacturing census, this paper documents new empirical relationships between input prices, output prices, and plant size and proposes a model of endogenous input and output quality choices by heterogeneous firms to explain...

This paper presents a tractable formalization and an empirical investigation of the quality-complementarity hypothesis, the hypothesis that input quality and plant productivity are complementary in generating output quality. We embed this complementarity in a general-equilibrium trade model with...

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...
