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...

This paper characterises and compares the spatial distribution of air traffic in the US and Europe across the network of airports for both continents for the period 1996 to 2006, using annual airline schedules from the Official Airline Guide databases. Several measures of traffic concentration...

The Internet Economy increases the integration among the subject involved in the production and diffusion of knowledge, in particular sources and interfaces of innovation: their action is amplified when Information and Communication Technology (ICT) favors the creation of an integrated network...

Zipf’s law is one of the best-known empirical regularities of the city-size distribution. 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...

This paper analyzes the growth of Metropolitan Statistical Areas in the PRC between 1992 and 2013 by focusing on the night-light radiance — a measure of economic activity — of connected subcity places that we refer to as a natural city. This paper documents the rapid growth of natural cities...

We study the impact of international long-distance flights on the global spatial allocation of economic activity. To identify causal effects, we exploit variation due to regulatory and technological constraints which give rise to a discontinuity in connectedness between cities at a distance of...

The new economic geography depicts spatial location as the key factor determining the growth performance of an economy and thus provides one of the most suitable frameworks to the study of transport infrastructures. The purpose of this paper is to exploit some of the analytical tools familiar to...

Many Alaskans depend on family-centered harvests of wild fish, wildlife, and plants in what could be considered a home production model. State and federal laws provide priorities for these “subsistence uses,” a divisive political issue in Alaska. We explore Alaska’s subsistence economies...

This paper addresses the simultaneous determination of fast-food availability on obesity rates through the use of instrumental variables, specifically the number of interstate exits in the county of residence. Using the 2005 Behavioral Risk Factor Surveillance Survey and self-collected data on...
