Informal contacts are extensively used by both firms and workers to find jobs and fill vacancies. The common wisdom in the economic literature is that jobs created through this channel are of better quality and pay higher wages than jobs created through formal methods. This paper explores the...

This paper studies the impact of NAFTA on informality and real wages in Mexico. Using a dynamic industry model with firm heterogeneity, it is predicted that import tariff elimination could reduce the incidence of informality by making more profitable to some firms to enter the formal sector,...

In this paper we make use of a matched employer-employee database for Italy to look at the spatial distribution of wages. Using this rich database we aim to open up the black box of agglomeration economies exploiting the micro dimension of interaction among economic agents, both individuals and...

We develop a method for identifying departures from relative factor price equality that is robust to unobserved variation in factor productivity. We implement this method using data on the relative wage bills of nonproduction and production workers across 170 local labor markets comprising the...

This paper is concerned with the urban wage premium and addresses two central issues about which the field has not yet reached a consensus: first, the extent to which sorting of high ability individuals into urban areas explains the urban wage premium and second, whether workers receive this...

The market is a place where people behave quite relentlessly. If one person is selling a particular commodity at a higher price than others, no one will buy that commodity from him, however virtuous or merciful he is known to be. Of course, the actual world does not always work exactly in this...

The paper investigates the relationship between underground activities and financial deepening. The access to external finance requires entrepreneurs to disclose credible information through formal documentation. This requirement may be impossible to oblige to for many informal producers who...

We develop a methodology for identifying departures from relative factor price equality across regions that is valid under general assumptions about production, markets and factors. Application of this methodology to the United States reveals substantial and increasing deviations in relative...

The striking geographical concentration of economic activities suggests that there are substantial benefits to agglomeration. However, the nature of those benefits remains unclear. In this paper we take advantage of a new dataset to quantify the role of one of the main contenders - the matching...

London is one of the world’s major cities, and one of its most diverse. London’s cultural diversity is widely seen as a social asset, but there is little hard evidence on its importance for the city’s businesses. Theory and evidence suggest various links between urban cultural diversity...
