Firm-destination heterogeneity and the distribution of export intensity

We derive closed-form expressions for the distribution of export intensity when firm-destination-specific revenue shifters are distributed gamma, Fréchet and Weibull in a two-country model trade with isoelastic demand. estimate parameters governing each type shifter across 72 countries. compare model’s fit to countries lognormal, gamma Fréchet/Weibull. While lognormal slightly outperforms other distributions, all considered reproduce salient features distributions within between quite successfully.
