We analyze demand for prepaid cellular voice and short message service (SMS) in South Africa by means of a demand-and-supply structural model based on a multinomial specification fitted to a cross-sectional data set on Vodacom customers collected in 2005. We find that consumers are very...

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 use the framework to analyse the impact of shocks that occur in one region...

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...

Despite substantial regional expenditures at both national and community level, European regional policies do not appear to deliver. The evidence suggests that neither efficiency gains nor reduced regional inequalities are attained. If there is any positive impact at all, then it is at the most...

Despite large regional policy expenditures, regional inequalities in Europe have not narrowed substantially over the last two decades, and by some measures have even widened. Income differences across states have fallen, but inequalities between regions within each state have risen. European...

This Paper studies the determinants of location choice by foreign investors in France. A new sample of almost 4000 location choices over ten years and 92 administrative locations is used to measure two important issues: To what extent do foreign investors cluster spatially and are the...

This Paper analyses the growth and employment effects of the 1994-99 Community Support Framework (CSF) for the Objective 1 Spanish regions, using a simple supply-side model estimated with a panel of regional data. The results suggest that the impact of the Structural Funds in Spain has been...

Should the geographic allocation of public investment aim at reducing regional inequalities or should it exclusively be concerned with the maximization of aggregate output? In this Paper I study the potential role of public investment in reducing personal welfare inequality, in combination with...

This paper estimates the impact of public investment on regional economic growth and convergence at the NUTS III level in Greece. Using a new database of public expenditure per region for the period 1978-2007, it proposes a model which captures not just the impact of public investment in Greek...

Business support policies designed to raise productivity and employment are common worldwide, but rigorous micro-econometric evaluation of their causal effects is rare. We exploit multiple changes in the area-specific eligibility criteria for a major program to support manufacturing jobs...
