Why do some people become entrepreneurs (and others don't)? Why are firms so heterogeneous, and many firms so small? To start, the paper briefly documents evidence from the empirical literature that the relationship between entrepreneurship and education is U-shaped, that many entrepreneurs...

This paper develops a model with multiple market locations in which the quality of intangible assets of firms, provided by management, determines the firms’ performance. Despite an ex ante symmetry of potential entrants, the equilibrium assignment of heterogeneous managerial skills to firms...

Recently, the interactions between product market structure and labor market outcomes have come under increased scrutiny. This paper considers the dynamic relationship between product market entry regulation and equilibrium unemployment and wages, both theoretically and quantitatively. The main...

Using Local Labour Systems (LLSs) data, this work aims at assessing the effects of sectoral shifts and industry specialization patterns on regional unemployment in Italy over the years 2004-2008, when huge worker reallocation caused by changes in the international division of labour occurred....

Industry mean wages in China have exhibited sharply increased dispersion since the early 1990s. The upward trend in differences of average wages among major industry groups parallels increases in wage and income inequality not only between rural and urban sectors but within the urban economy as...

This note is a companion to the Lilien (lilien) and Modified Lilien (mlilien) commands for computing the relative indices in STATA. The note illustrates the main features of the commands with an application to the structural determinants of regional unemployment.

We consider a dual labor market with a frictional formal sector and a competitive informal sector. We show that the size of the informal sector is generally too large compared to the optimal allocation of the workers. It follows that our results give a rationale to informality-reducing policies.

This paper studies the impact of product and labor market regulations on informality and unemployment in a general framework where formal and informal firms are subject to the same externalities, differing only with respect to some parameter values. Both formal and informal firms have monopoly...

Recent research has documented a U-shaped industrial concentration curve over an economy's development path. How far can neoclassical trade theory take us in explaining this pattern? We estimate the production side of the Heckscher-Ohlin model using industry data on 44 developed and developing...

This paper studies the effects of the introduction of unemployment compensation (UC) in countries characterized by pervasive informality. We provide a simple framework to analyze the impact of UC on the allocation of workers between formal and informal activities, as well as the allocation of...
