A model is considered in which optimal search intensity is a result of a trade-off between short-run losses due to higher search costs (more interviews, commuting...) and long-run gains due to a higher chance to find a job. We show that this optimal search intensity is higher in areas...

The possible effects of higher immigration, raising unemployment and lowering earnings for locals, has been a contentious empirical issue and it has recently come to the fore in Britain. Most studies that look across local labour markets, chiefly for the US but recently for the UK, have found...

This paper analyzes empirically a public policy promoting industrial clusters in France. Cluster policies have become popular in many countries but have not been extensively evaluated empirically. We use data on production and employment for firms that benefited from the policy and on firms that...

Geography shapes economic outcomes in a major way. This Paper uses spatial empirical methods to detect and analyse trade patterns in a historical dataset on Chinese rice prices. Our results suggest that spatial features were important for the expansion of interregional trade. Geography dictates,...

Following the rationale for regional redistribution programmes described in the official documents of the European Union, this Paper studies a very simple multi-country model built around two regions: a core and a periphery. Technological spillovers link firms’ productivity in each of the two...

We apply a novel measure of intergenerational mobility (IM) developed by Güell, Rodríguez Mora, and Telmer (2014) to a rich combination of Italian data allowing us to produce comparable measures of IM of income for 103 Italian provinces. We then exploit the large heterogeneity across Italian...

We survey the recent empirical literature on structural models of market entry and spatial competition in oligopoly retail industries. We start with the description of a framework that encompasses various models that have been estimated in empirical applications. We use this framework to discuss...

Using a spatial competition framework with three ex ante identical firms, we study the effects of a horizontal merger on quality, price and welfare. The merging firms always reduce quality. They also increase prices if demand responsiveness to quality is sufficiently low. The non-merging firm,...

Market size and transport costs are important ingredients of international trade. We propose to look at these issues from a different perspective. Using a Hotelling duopoly model with quadratic transport costs, we analyse the welfare effects of international trade between two countries that...

We study the relationship between competition and quality within a spatial competition framework where firms compete in prices and quality. We generalise existing literature on spatial price-quality competition along several dimensions, including utility functions that are non-linear in income...
