This paper focuses on several different measures of OECD countries’ energy intensity levels, plots their trends, applies a number of techniques to determine whether those intensities are converging, explores the importance of that convergence, and estimates the future steady-state or long-run...

An inverted-U relationship between GDP per capita and three urban transport-related emissions is tested (using data from 84 cities). Per capita urban transport-related emissions of CO, VHC, and NOx increase and then decline at observed income levels—a result driven by a similar inverted-U...

Heterogeneous panel causality tests are employed to consider the relationship between urbanization change and economic growth (i.e., differenced logged GDP per capita). Income- and geography-based panels demonstrated substantial variation in that relationship. Urbanization caused economic growth...

This paper summarizes and expands the state-of-the-art understanding of the urbanization, development, environment, and inequality nexus. Economic growth/development, urbanization, and energy/electricity consumption are all highly correlated. While urbanization may be more evidence of economic...
