摘　　要：本文构建了劳动力市场信息不完全情形下企业和求职者的双边搜寻均衡工资模型。最终实现工资由潜在工资水平和劳企双方的搜寻成本综合确定,它对潜在工资的偏离程度反映不完全信息给工资定价带来的效率损失。双边随机前沿分析表明,信息不完全导致的搜寻成本可解释最终实现工资离散度的62%,农民工和企业综合搜寻成本使实现工资水平相对于潜在工资水平上升幅度达6.54%。这些印证了2008年前后珠三角地区"民工荒""招工难"等问题。In this paper we build a two-tiered search model of enterprises and workers under incomplete information in the labor market to study the effect of search cost on the final equilibrium wage. The ultimate realized wage is determined by the potential wage levels and search costs of workers and enterprises. The deviation of the realized wage from the potential wage reflects the efficiency loss due to information incompleteness. Empirical evidence from the two-tiered stochastic frontier analysis shows that search costs can explain 62 % of the re- alized wage in the wage dispersion and the total search cost makes the wage 6.64% higher than the potential wage. These results reflect the problem of ＂rural worker shortage＂ and ＂recruitment difficulties＂ around 2008 in China.
