风险偏好对个体收入的影响--来自中国城镇劳动力市场的证据

摘要

传统收入理论一直忽视了一个重要的因素———风险偏好。基于2009年农村—城市移民调查数据（RUMIC2009），本文考察了风险偏好对个体收入的影响。实证结果表明，风险偏好对个体收入有显著正向影响，且对城镇居民的影响大于农民工；风险偏好对创业者和工资获得者收入均有显著正向影响，不过对城镇居民创业者收入作用不显著；此外，风险偏好对女性收入的影响在城镇居民中大于男性，在农民工中稍小于男性。风险偏好对过低的年龄组群体收入没有显著影响，且随着年龄的提升，风险偏好对个体收入的作用也逐渐增强。采用父母的风险偏好作为工具变量，纠正可能的内生性问题后，风险偏好对个体收入的正向影响仍然存在。%A factor has been ignored by the traditional income theory,namely risk preference.Using the 2009 survey data of Rural -Urban Migration in China (RUMIC2009 ),this paper analyzes the effect of risk preference on individual income. Empirical results show that risk preference has a significant positive effect on individual income,but the effect in urban residents is bigger than that in migrants;Risk preference improves the income of entrepreneurs and wage earners significantly,but the effect is not significant for urban entrepreneurs.Besides,the effect of risk preference on female income is bigger than that on male income in urban residents,but a little smaller than that on male income in migrants.Risk preference has no significant effect on individual income in the group who are too young,and the effect becomes bigger and bigger as age increases.By using the risk preference of parents as the instrumental variable to resolve the endogenous problem, risk preference still has significant positive effect on individual income.
