This paper surveys the theoretical and empirical literature on the relationship between the spatial distribution of economic activity and transportation costs. We develop a multi-region model of economic geography that we use to understand the general equilibrium implications of transportation...

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...

This paper uses city-level data to examine the impact of a first wave of railroad construction in Sweden, between 1855 and 1870, from the 19th century until today. We estimate that railroads accounted for 50% of urban growth, 1855-1870. In cities with access to the railroad network, property...

Environment, history and chance, shape people and cultures, which shape cities, which shape people and cultures, and so on, in a Systemic Retroactive Game. The quintessential essence of Isotropic (or Isobenefit) Urbanism is to solve Systemic Retroactive Game problems downstream rather than...

The quintessence of the Isobenefit Urbanism presented here, is to offer fair, walkable and green cities. Its three cornerstones are Modernity, Humanity and Naturality, which are exposed by five principles. The latter, rather then describe The ideal city, which doesn’t exist outside our own...

Previous researches have proved the existence of a causal relationship between the concentration of jobs in a city and the income of inhabitants. Other researchers have studied the close and even nearly causal relationship between those variables and the degree of accessibility or of...

Zipf’s law is one of the best-known empirical regularities in urban economics. There is extensive research on the subject, where each city is treated symmetrically in terms of the cost of transactions with other cities. Recent developments in network theory facilitate the examination of an...
