Trade data are typically reported at the level of regions or countries and are therefore aggregates across space. In this paper, we investigate the sensitivity of standard gravity estimation to spatial aggregation. We build a model in which initially symmetric micro regions are combined to form...

This paper explores the role of retailers as an urban amenity. Using data for Swedish rural and city municipalities for 2002-2008, "accessibility to shops" measures are constructed for the shops in the municipalities and in the hosting regions separately to examine the relationship between...

Metropolitan areas --unions of nearby built-up locations within which people travel on a day-to-day basis among places of residence, employment, and consumption--serve as a fundamental unit of economic analysis. But existing delineations of U.S. metro areas--including metropolitan Core-Based...

The U.S. population is becoming increasingly urban and has gradually shifted to the south and west. Policy restrictions have played a role in preventing dynamic areas expanding, and when they do expand it can be through low-density housing sprawl. Land use restrictions and a sluggish housing...

Geographic concentration in U.S. hog production from 1974 to 1996 is investigated using a measure based on Theil's entropy index. For the U.S. as a whole, geographic concentration is occurring at a slow rate, both for hog farms and hog numbers. However, for particular states,primarily in the new...

As green building activity continues to rise across the country, some state governments decided to create incentives that would motivate developers to voluntarily pursue third party certification for their real estate projects in order to assist in meeting sustainability and environmental goals....

Current sources of data on rental housing – such as the census or commercial databases that focus on large apartment complexes – do not reflect recent market activity or the full scope of the U.S. rental market. To address this gap, we collected, cleaned, analyzed, mapped, and visualized 11...

Airport cities – concentrations of employment – may have emerged near the major airports of large metropolitan areas. As the U.S. economy is nearly three times as air-intensive as it was in the 1950s, the “aerotropolis” thesis holds that airport cities are a direct consequence of...

We use transaction-level data to study changes in the concentration of US imports. Concentration has fallen in the typical industry, while it is stable by industry and origin country. The fall in concentration is driven by the extensive margin: the number of exporting firms has grown, and the...
