To identify communication externalities in French cities, we exploit a unique survey recording workplace communication of individual workers. Our hypothesis is that in larger and/or more educated cities, workers should communicate more. In turn, more communication should have a positive effect...

Economists have a well-developed theory of value but the theory of why people hold the values they do is rudimentary at best. In spite of the fact that it is common to argue that values are important, most work on values is normative and the positive theory of values is relatively under-...

Using administrative employer-employee data from Germany, I exploit two reductions of tax breaks for commuting in 2003/4 and 2006/7 to estimate commuting costs’ effect on the decision to switch job and move house. Standard theory predicts that higher commuting costs should lead to increased...

We consider the literatures on urban systems and New Economic Geography to examine questions concerning agglomeration and how areas respond to shocks to the economic environment. We first propose a diagrammatic framework to compare the two approaches. We then use this framework to study a number...

This paper considers the ways geographers (proper) and (geographical) economists approach the study of economic geography. It argues that there are two areas where the approach of the latter is more robust than the former. First, formal models identify which assumptions are crucial in obtaining...

We use data for metro areas in the United States, from the US Census for 1900 - 1990, to test the validity of Zipf's Law for cities. Previous investigations are restricted to regressions of log size against log rank. In contrast, we use a nonparametric procedure to calculate local Zipf exponents...

A diagrammatic framework is developed to study the economic linkages between regions or cities. Hitherto, such linkages have not been a focus of the literature. The framework is used to analyse the impact of shocks that occur in one region (for example, productivity improvements or increases in...

We develop a diagrammatic framework that can be used to study the economic linkages between regions or cities. Hitherto, such linkages have not been the primary focus of either the theoretical or empirical literatures. We show that our general framework can be used to interpret both the New...

Both educational attainment and school quality are typically lower in disadvantaged areas than others and much recent policy attention has been focused on each. This paper looks at the quality problem, exploring the relationships between disadvantaged contexts, what schools do, and the quality...
