【摘要】：生命周期劳动供给理论预测工人的劳动供给对短期工资波动有正向的反应,然而不少研究发现国外出租车司机劳动供给弹性是负的。国内出租车司机的情况如何呢?文章用杭州出租车GPS行程数据分析了司机的内延性和外延性劳动供给。为解决由测量误差和同事效应产生的内生性问题,我们用司机当天遇到的长途载客次数作为其每小时工资的工具变量,进而探讨每小时工资对司机劳动供给时间的影响。我们发现,杭州出租车司机的内延性和外延性劳动供给工资弹性均显著为正,这说明政府增加司机每公里燃油补贴等政策的确能激励司机增加劳动供给。另外,这也说明放松出租车市场的价格管制能使司机更好地根据市场需求优化自己的工作决策。
[Abstract]:Life cycle labor supply theory predicts that workers' labor supply has a positive response to short-term wage fluctuations. However, many studies have found that the elasticity of foreign taxi drivers' labor supply is negative. What is the situation of taxi drivers in China? This paper analyzes the internal and external labor supply of drivers with Hangzhou taxi GPS travel data. In order to solve the endogenous problem caused by measurement error and coworker effect, we use the number of long-distance passenger carried by the driver on the same day as the tool variable of the hourly wage, and then discuss the effect of the hourly wage on the driver's labor supply time. We find that the wage elasticity of both the internal and external supply of taxi drivers in Hangzhou is significantly positive, which indicates that the government policies such as increasing fuel subsidies per kilometer of drivers can indeed encourage drivers to increase the supply of labour. In addition, it also shows that the relaxation of taxi market price controls will enable drivers to better optimize their job decisions in accordance with market demand.
