The Effects of Labour Market Policies in an Economy with an Informal Sector
构建了一个包含非正规部门的均衡搜索匹配模型，分析劳动力市场政策对产出、就业分布和工资分配的影响，帮助理解政策在双重劳动力市场中的作用。
In this article, we build an equilibrium search and matching model of an economy with an informal sector. Our model extends Mortensen and Pissarides (1994) by allowing for "ex ante" worker heterogeneity with respect to formal-sector productivity. We use the model to analyse the effects of labour market policy on informal-sector and formal-sector output, on the division of the workforce into unemployment, informal-sector employment and formal-sector employment, and on wages. Finally, we examine the distributional implications of labour market policy; specifically, we analyse how labour market policy affects the distributions of wages and productivities across formal-sector matches.
