We describe a model that integrates a multi-regional input-output model of the U.S. (50 states and the District of Columbia) with the national highway network. Interstate commodity shipments are placed on a congestible highway network. Simulations of major choke-point disruptions redirect...

The literature on China indicates that the concentration of economic activities in China is less than in other industrialized countries. Institutional limits are largely held responsible for this finding (e.g. the Hukou system); firms and workers are not able to take full advantage of the...

In this paper we show that the double Pareto lognormal (DPLN) parameterization provides an excellent fit to the overall US city size distribution, regardless of whether “cities” are administratively defined Census places or economically defined area clusters. We then consider an economic...

China’s Hukou system poses severe restrictions on labor mobility. This paper assesses the consequences of relaxing these restrictions for China’s internal economic geography. We base our analysis on a new economic geography model. First, we obtain estimates of the important model parameters...

Using a rich data set on the EU regions, we analyze the relevance of two possible determinants of a region’s resilience to shocks, the degree of urbanization and specialization. We take the Great Recession, the economic and financial crisis that started in 2008, as our shock and then analyze...

We analyze the first data set on consistently defined functional urban areas in Europe and compare the European to the US urban system. City sizes in Europe do not follow a power law: the largest cities are “too small” to follow Zipf’s law.

The paper combines an economic-geography model of agglomeration and periphery with a model of species diversity and looks at optimal policies of biodiversity conservation. The subject of the paper is "natural" biodiversity, which is inevitably impaired by anthropogenic impact. Thus, the economic...

Regional productivity differences provide scope for productivity-enhancing labor mobility. Redistribution reduces relocation incentives through higher taxes or lower transfers. Combining an intensive labor supply margin with an extensive, productivity-enhancing migration margin, we determine how...

This article investigates whether the distance between origin and destination has played an increased role in shaping Italy’s domestic tourism flows during the recent years of economic recession. Indeed, the occurrence of closer tourism destinations, as a consequence of the economic crisis,...

After World War II, town twinning became popular, notably in Germany. This was mainly a reaction to the war experience, and it was aimed at creating renewed international understanding and co-operation between German cities and cities in other countries. The contacts created by town twinning...
