Social Influence and Consumption: Evidence from the Automobile Purchases of Neighbors
基于芬兰两省多年居民汽车购买数据，发现邻居（尤其是近期和地理上最近的邻居）的购买行为会影响消费者的汽车选择，且情感偏见（如嫉妒）的作用不大。
This study analyzes the automobile purchase behavior of all residents of two Finnish provinces over several years. Using a comprehensive data set with location coordinates at the individual consumer level, it finds that the purchases of neighbors, particularly in the recent past and by those who are geographically most proximate, influence a consumer's purchases of automobiles. There is little evidence that emotional biases, like envy, account for the observed social influence on consumption.
