A spatial simultaneous-equations growth equilibrium model estimated by GS2SLS and GS3SLS estimators is used to determine the interdependence between small business growth and poverty. The parameter estimates are mostly consistent with the theoretical expectations. The coefficients for the...

This paper begins by investigating the Obama administration’s rationale of promoting regional innovation clusters (RICs) in the context of increasing public concerns on the Strategy for American Innovation. Next, the connections between RICs and existing research and policies in clusters,...

Amid changing attitudes about the environment and increasing sustainability concerns, many countries around the world aim to curb waste generation, especially the generation of hazardous wastes. Beginning in the late 1970’s and occurring increasingly since, governments and international bodies...

A panel estimation of county prevalence of obesity indicates that while the percentage of the population with a completed college degree and the number of food stores available per thousand population are negatively and significantly correlated to county obesity rates, mean commuting time,...

Can sustainability be enhanced by maximizing the sum of private and social benefits from an industry? This might take place, for example, by identifying production options that increase profitability side-by-side with societal goals such as renewable energy production and carbon sequestration,...

A characteristic of the empirical literature on internal population migration is widely varying results and often conflicting conclusions regarding relative importance of explanatory factors. There are a number of possible explanations for these conflicting findings, some of which have received...

Previous research has documented increased lung cancer incidence and mortality in Appalachia. The current study tests whether residence in coal mining areas of Appalachia is a contributing factor. We conducted a national county-level analysis to identify contributions of smoking rates,...
