Linguistic distance and economic development: A cross‐country analysis

Abstract

AbstractThis study investigates the relationship between access to domestic and international communication and economic development. It does so by constructing two indices of linguistic distance, domestic and international, capturing language acquisition costs, which are higher when acquiring linguistically more distant languages. The domestic linguistic distance index captures the constraints of communication among speakers of different mother tongues within a country, while the international linguistic distance index captures the constraints of global communication via English. This study’s results reveal a negative association between domestic linguistic distance and GDP per capita, whereas international linguistic distance has no significant association. Moreover, by investigating the mechanisms of the negative association of the domestic linguistic distance, we find that communication difficulty among different language groups hinders economic development through a channel of less employment requiring communication‐based operations. Furthermore, we determine that the negative association of the domestic linguistic distance may be mainly driven by relatively poor countries such as many in Africa.
