Simulating commercial policy in a small, open dual economy with urban unemployment: A general equilibrium approach
基于肯尼亚数据构建两部门数值一般均衡模型，分析存在城市工业劳动力市场扭曲和失业时的次优关税政策，发现次优政策的效率提升远小于直接消除工资扭曲。
A two‐sector numerical general equilibrium model calibrated on Kenyan data is used to consider second‐best tariff policy in an economy with a distorted market for urban‐industrial labour and urban unemployment. The results illustrate the sensitivity of second‐best policy to the way the administered urban wage is determined (whether it is fixed primarily in terms of food or the manufactured good), and to the degree of inter‐sectoral mobility of capital. Efficiency gains from moving to a second‐best policy are shown to be small in comparison with the gains from eliminating the wage distortion in the first place.
