ADJUSTMENTS OF AGRICULTURAL PRODUCTIVITY FOR NITROGEN EFFLUENT IN THE GREAT PLAINS AgEcon
Rezek, Jon P.; Perrin, Richard K..
Traditional measures of agricultural productivity only incorporate those inputs and outputs that are recorded in market transactions. However, such measures do not account for externalities such as environmental damage. This study uses an output distance function framework to estimate a Malmqvist productivity index for a panel of Great Plains states then adjusts this index by incorporating nitrogen effluent into the analysis. We estimate that long-run environmentally-adjusted productivity growth was approximately 13 percent below the unadjusted rate during the sample period. However the environmentally sensitive productivity rate actually exceeded the unadjusted rate in recent years, reflecting reductions in the discharge of agricultural nitrogen into...

Environmentally Adjusted Agricultural Productivity in the Great Plains AgEcon
Rezek, Jon P.; Perrin, Richard K..
This study adjusts 1960-1996 agricultural productivity gains in a panel of Great Plains states to account for the discharge of pesticide and nitrogen effluents into the environment. The agricultural-environmental technology is approximated with translog distance functions that allow us to contrast traditional versus environmentally adjusted productivity gains. Findings indicate technical change has been increasingly biased toward environmentally friendly production. While the environmental adjustment reduced overall productivity gains during the sample period, in recent years adjusted productivity outpaced the traditional measure, reflecting the pro-environment bias in technical change.

SHADOW PRICES OF SULFUR DIOXIDE ALLOWANCE IN PHASE I ELECTRIC UTILITIES AgEcon
Rezek, Jon P..
The divergence of SO2 allowance price from initial estimates has spawned substantial interest since emission trading began. This paper uses non-parametric DEA to calculate technical, output revenue and allocative efficiency measures of Phase I electric plants. The allocative efficiency measure is then used to determine if allowance prices actually reflect opportunity costs.
