Guided by a simple theoretical framework, we decompose countries market shares into the contribution of the number of firm-products, their average attributes (quality and efficiency) and heterogeneity around the mean. To further explore the role of exceptional firms, we develop a novel decomposition that identifies the contribution of deviations from continuous distributions. We then study how the distribution of firm-level characteristics varies across countries. Our results shed new light on how firms shape aggregate economic performance.application/pdfengL'accés als continguts d'aquest document queda condicionat a l'acceptació de les condicions d'ús establertes per la següent llicència Creative CommonsFirms and economic performance: A view from tradeinfo:eu-repo/semantics/workingPaperus importsfirm heterogeneityinternational tradepricesqualityvarietygranularity.Macroeconomics and International Economicsinfo:eu-repo/semantics/openAccess
