The energy savings from tree shade coincide with peak electricity demand during summer months, creating an opportunity for utilities to use tree protection policies as demand side management tools. We apply a quasi-experimental research design to identify the change in residential energy caused...

This study employs a choice experiment approach to investigate consumers’ preferences and willingness-to-pay (WTP) for organic food products. We use mixed logit and latent class models to examine preference heterogeneity. The results revealed significant heterogeneity in preferences for...

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...

In this study, we empirically examine the effectiveness of regulatory actions on wastewater treatment plants in Illinois with careful attention to endogeneity issues that might have caused biased estimates in previous studies. We show that Pooled OLS and Fixed Effect models, which are the...

This study investigated the extent to which statistical heterogeneity among results of multiple studies on soil organic carbon (SOC) sequestration rate in response to conventional tillage (CT) and no-till (NT) can be related to one or more characteristics of the studies. The analysis employed a...

In low potential agricultural areas like the Honduran hillsides characterized by soil degradation and erosion, organic agriculture can provide a means to break the downward spiral of resource degradation and poverty. We use original survey data to analyze the factors influencing the decision to...
