Trade and ethnolinguistic differences: A replication and extension
复制并扩展了Dickens（2022）关于贸易对民族间语言差异影响的研究，使用改进的贸易收益指标，证实了贸易的作用，同时揭示了区分族际与族内贸易的困难，并提供了开源计算框架。
Abstract We revisit the role of trade on long‐run inter‐ethnic linguistic differences. Dickens (2022) hypothesized that neighboring languages are more similar when agriculture provides potential gains from inter‐ethnic trade. Since his empirical approach confounds inter‐ and intra‐ethnic trade, we replicate his main analysis using improved measures of potential inter‐ethnic gains from trade. Our results confirm the role of trade in inter‐ethnic linguistic differences while showing the difficulty of disentangling the role of inter‐ versus intra‐ethnic trade. We also provide an open‐source computational framework to replicate both sets of results, which others can use to produce original replicable economic research.
