The names of traders should not matter if information is symmetric across traders. By examining export data from Chinese customs, we find persistent lexicographic biases in firm-level export records. Firms whose names are lexicographically earlier in the Chinese-character rank export more to countries that have greater language proximities to Chinese, while firms whose names are lexicographically earlier in the English-romanization rank export more to countries that have greater language proximities to English. The lexicographic biases signify linguistic visibility as a source of comparative advantage in international trade.
