本文考察了泰国曼谷城市劳动力市场中移民之间的非市场互动。我们测试以前移民的人口规模和劳动力市场表现是否会对来自同一原籍省份的新移民产生外部性。在控制了原籍固定效应、时间固定效应和原籍和年份相关冲击后，我们的实证结果表明：(1)以前流动人口在市场上的相对人口规模降低了新流动人口的就业概率(替代效应)，(2)以前流动人口的就业概率增加了新流动人口的就业概率(正外部性)，(3)当以前流动人口的就业概率较高时，规模效应变为正，这表明在信息规模经济中存在一个门槛。研究结果表明，当前向流动人口在目的地劳动力市场的效率足够高时，正向信息规模效应主导负替代效应。
This paper examines the nonmarket interactions among migrants in the urban labor market of Bangkok, Thailand. We test whether the population size and the labor-market performance of previous migrants have externalities to new migrants who have moved from the same province of origin. Our empirical results, which control origin fixed effects, time fixed effects, and origin- and year-specific correlated shocks, show that (1) the relative population size of previous migrants in the market decreases the employment probability of new migrants (substitution effect), (2) the employment probability of previous migrants increases that of new migrants (positive externalities), and (3) when the employment probability of previous migrants is high, however, the scale effect becomes positive, which demonstrates a threshold in the informational scale economies. The results imply that positive informational scale effect dominates negative substitution effect when the efficiency of previous migrants is sufficiently high in the destination labor market.
