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...

Researchers typically invoke theoretical assumptions to estimate mark-ups. Instead, we directly obtain mark-ups by surveying Pakistani soccer-ball producers. We document six facts: (1) Mark-ups are more dispersed than costs; (2) Mark-ups and costs increase with firm size; (3) The mark-up...

This short paper examines the effect of exporting on within-plant wage distributions in employer-employee data on Mexican manufacturing plants. Using the late-1994 peso devaluation interacted with initial plant size as a source of exogenous variation in exporting and focusing on wages at the...

This paper examines the extent to which the destination of exports matters for the input prices paid by firms, using detailed customs and firm-product-level data from Portugal. The authors use exchange rate movements as a source of variation in export destinations and find that exporting to...

This paper examines how schools' choices of class size and households' choices of schools affect regression-discontinuity-based estimates of the effect of class size on student outcomes. We build a model in which schools are subject to a class-size cap and an integer constraint on the number of...
