The Moynihan Institute’s program for T rade\, Development and Political Economy program presents a talk by Vaness a Alviarez.

We study the relationship between industry concentratio n and aggregate markups in a model of firm-to-firm trade with two-sided ma rket power. The theory shows that the aggregate markup in an input market is a linear function of two concentration measures: it increases with conc entration among suppliers and decreases with concentration among buyers. W e use Colombian import data from 2009-2020 to analyze trends in import and export concentration during the sample period and the corresponding evolu tion of aggregate markups.

Our analysis shows that considering two- sided concentration and market power yields a more comprehensive understan ding of the evolution of aggregate markups in international trade compared to standard models where supplier concentration is the only relevant stat istic.
