The Role of Cultural Clustering in Attracting New Immigrants
研究认为新移民因信息不完全而聚集在文化同质群体中，但群体规模过大时吸引效应会消失。基于1980年代中期至1990年代中期OECD国家移民面板数据，发现文化社区吸引新移民，但效应因来源国和目的国而异，且超过一定规模后降为零。
Abstract This paper argues that new immigrants cluster in culturally homogeneous groups in the host country because of imperfect information. However, a pulling effect exists provided that the cultural communities are not too large. With a panel of migration flows to the major O.E.C.D. countries from the mid 1980s to the mid 1990s, it is shown that the existence of similar cultural communities attracts new immigrants. However, the effect is not homogeneous for all types of source and destination countries. Furthermore, the pulling effect is shown to fall to zero for cultural communities above a certain threshold size.
