This paper shows that the top 1 percent of exporters critically shape trade patterns, using firm-level data from 32 countries. In particular, variation in average firm size (the intensive margin) explains over two thirds of the variation in the sector distribution of exports across countries,...

We show that very large firms shape country export patterns. Among 32 countries, the top firm on average accounts for 14% of a country's total (non-oil) exports, and the top five firms make up 30%. These export superstars are also important in the sectoral distribution of exports. Variation in...

This paper presents new data on the micro structure of the export sector for 45 countries and studies how exporter behavior varies with country size and stage of development. Larger countries and more developed countries have more exporters, larger exporters, and a greater share of exports...
