Urban spatial structure and economic growth in Spanish metropolitan areas [PDF]
, 2011 There is a large literature on the existence of agglomeration economies, as shown in the surveys by Moomaw (1983) or Gerking (1993). The benefits of these economies arise from multiple sources, but some negative externalities might also emerge.

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective
Advanced Electronic Materials, EarlyView.Cylindrical reconfigurable intelligent surfaces are explored for low‐complexity beam steering using one‐bit meta‐atoms. A multi‐level modeling approach, including optimization‐based synthesis, demonstrates that even minimal hardware can support directive scattering.

Changes in Alcohol Retail Laws and Foot Traffic at Liquor Stores
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT We study how expanding alcohol availability at grocery and convenience stores affects consumer traffic in liquor stores by leveraging recent changes in state‐level alcohol distribution laws in a difference‐in‐difference quasi‐experimental design.

Second-best Congestion Pricing Schemes in the Monocentric City [PDF]
This paper considers second-best congestion pricing in the monocentric city, with endogenous residential density and endogenous labour supply. A spatial general equilibrium model is developed that allows consideration of the three-way interactions ...

The village and the city: a diagnostic study of the spatial embedding patterns in villages absorbed by cities in Bahrain [PDF]
, 2009 During the growth of cities villages are frequently absorbed into the fabric of that conurbation. But what are the consequences of this? To what extent and how well do these villages become part of the overall fabric of the city?

Temperature and Farm Labor in Nigeria
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT We estimate the impact of temperature shocks on the composition of farm labor in rural Nigeria using a nationally representative household panel survey. Leveraging plausibly exogenous year‐to‐year variation in growing season temperatures, we find that warmer temperatures significantly alter farm labor composition, prompting a substantial shift

Urban growth and subcenter formation: A trolley ride from the Staples Center to Disneyland and the Rose Bowl [PDF]
The long-term trends of urbanization suggest: not only have more cities formed, but the leading metropolises have grown larger, with a number of peripheral subcenters developing over time.

Where It Is Better to Live: In an "European" or an "American" City? [PDF]
We start from the well known fact that, in most European cities, central locations are occupied by rich households; while in American cities, they are occupied by poor households.

Advanced Energy and Sustainability Research, EarlyView.Hydrogen‐powered aviation offers a transformative pathway to zero‐emission flight by eliminating in‐flight CO2 emissions. Key considerations include propulsion systems (fuel cells and hydrogen combustion), cryogenic storage and insulation challenges, infrastructure and cost barriers, and supply‐chain constraints.
