Zoning decisions related to residential lot size and density affect residential land value. Effects of size on residential parcel value in Roanoke County, VA, are estimated with fixed effects hedonic models. Parcel size; elevation; soil permeability; proximity to urban areas, malls, and roads;...

This paper demonstrates that linear regression models with an AR(1) error structure implicitly assume that y{t} does not Granger cause any of the exogenous variables in X{t}. An indirect test of the common factor restrictions based on this Granger non-causality is proposed and shown to...

This paper focuses on the practice of serial correlation correcting of the Linear Regression Model (LRM) by modeling the error. Simple Monte Carlo experiments are used to demonstrate the following points regarding this practice. First, the common factor restrictions implicitly imposed on the...

In response to economic and environmental concerns, Water-Recycling Technologies (WRT) have been developed to reduce water consumption and surface run-off in horticultural operations. Water recirculation provides the potential for water conservation and may also reduce grower costs in the long...

The effects of phosphorus (P)-based nutrient management plans on economic and environmental risks of dairy and dairy-poultry farms in Virginia were evaluated. Phosphorus-based nutrient management plans can greatly reduce P runoff risk but also reduce farmers' returns. P-based plans cause greater...

The purpose of this paper is to empirically compare the out-of-sample predictive capabilities of artificial neural networks, logit and probit models using dichotmous choice contingent valuation survey data. The authors find that feed-forward backpropagation artificial neural networks perform...

Emission trading programs have been discussed with respect to achieving water quality objectives and future caps on carbon emissions. A significant part of this literature explores the institutional and technical design issues associated with trades involving nonpoint effluent sources and carbon...

We evaluate incentives of forest landowners for sequestering and trading carbon, given the risk of carbon loss from hurricanes, and an opportunity to insure their losses. Results of simulation model reveal that the effect of hurricane risk depends on the variability of returns from carbon and...

Rotational grazing can potentially reduce greenhouse gas (GHG) emissions from animal operations. This study investigates potential GHG reductions from rotational grazing farm operations under alternative procedures for defining a carbon credit. As applied to a case study cow-calf operation, GHG...
