A surface water quality valuation index is developed and used to compare counties across the Appalachian Region. This index was based on a meta-analysis of non-market water quality valuation studies along with an application of benefit transfer. The results reveal that Pennsylvania, Georgia, and...

The marginal propensity to spend on food out of food stamps (MPSFS) is a key indicator of the fungibility of food stamp income. This fungibility has important implications for food stamp policy. Studies estimating the MPSFS use very different methods and come to very different conclusions...

A meta-analysis of reported water demand elasticities shows that publication selection bias results in water demand estimates that overstate price elasticities. The analysis uses panel data estimators to measure and adjust for publication bias. A random effects estimator is used to derive water...

The study investigates whether African agricultural efficiency levels has been improving or not and what drives its over the years based on 442 frontier studies using meta-regression analysis. The results show that mean efficiency estimates from studies decrease significantly as year of survey...

This study examines the systematic evidence entailed in existing research on consumers’ evaluation of biotechnology in food products. The extant literature related to this topic typically originates from a variety of research disciplines, but shares an underlying focus in dealing with the...

The literature on the impacts of biofuels on food prices is characterized by contradictory findings and a wide range of estimates. To bring more clarity to this issue, we review studies on U.S. corn ethanol expansion released between 2008 and 2013. Normalizing corn price impacts by the increase...

The impact of experience on entrepreneurial performance has been widely tested. Although experience is expected to positively impact performance, results are varied. This research synthesizes the current literature by determining systematic sources of variation through both exploratory and...

The selection of appropriate parameters for computable general equilibrium (CGE) models critically affects the results of applied economic modeling exercises. Valid and reliable parameter selection models are needed, and typically comprise direct estimation, expert opinion, or copycatting of...
