THE INFORMATION EFFECTS OF ORIGIN ON MIGRANTS' JOB SEARCH BEHAVIOR*
研究发现，移民原籍地与目的地劳动力市场的相似性（如就业增长差异）能显著影响其求职时长，尤其对农村到城市的移民（除南方农村外）效果明显。
"Migrants are generally assumed to gather specific information about the destination primarily through physical contact, or through family, friends, and acquaintances. In this paper, I propose an additional source of information: similarities between origin and destination labor markets. Data from the 1983-1987 PSID [Panel Study of Income Dynamics] are used in a two-stage least squares model of postmove search duration in the U.S. Rural-to-urban migrants (except for rural Southerners) exhibit significantly lower search duration than other groups, controlling for productivity-related characteristics and postmove earnings. In addition, employment growth differences between origin and destination are found to be better predictors of search duration than are differences in average earnings."
