Returns to Foreign Language Skills in a Developing Country: The Case of Turkey
基于2007年约6000名土耳其男性工资收入者的数据，分析英语、俄语、法语、德语和阿拉伯语等外语技能对收入的影响，发现英语和俄语能力能带来正向收入回报，且回报随熟练度提高而增加。
This paper analyses the economic value of foreign languages in Turkey using data on some 6000 adult male wage-earners in 2007. We find positive earnings returns to proficiency in English and Russian, which increase with the level of competence. French and German skills are also positively rewarded, although their return seems mostly linked to the likelihood to hold specific occupations. In contrast, knowing Arabic does not generate an earnings premium. Focusing on English, we check for heterogeneous returns along the conditional earnings distribution. The results are qualitatively invariant when we account for misclassification errors in self-reported English skills.
