In this paper, we show that this trade-promoting effect of language is likely to reflect cultural ties, rather than lower costs of communication or similar institutions. Analyzing unique data for a single-language country, Germany, we find that similarities in the local dialect between regions have a sizable and significant positive impact on intra-national trade. We interpret this finding as evidence for the effect of culture on trade. KW - language KW - culture KW - trade costs KW - gravity KW - dialects ER -
