CAN SEARCH-MATCHING MODELS EXPLAIN MIGRATION AND WAGE AND UNEMPLOYMENT GAPS IN DEVELOPING ECONOMIES? A CALIBRATION APPROACH*
通过校准方法检验搜索匹配模型是否与发展中国家数据一致，发现加入额外摩擦后模型比传统哈里斯-托达罗模型更符合实际。
ABSTRACT A recent theoretical literature tries to understand the migration pattern in developing economies through the lens of search-matching (SM) models, but there has been little empirical support for these models. This paper tries to fill this gap by examining whether the models are consistent with the data from developing economies. Combined with some suggestive statistics, our calibration exercise reveals that when augmented with additional frictions (fixed costs of starting up new businesses and mobility costs), our SM model can account for the data and is at least more consistent with the data than traditional Harris–Todaro models.
