Agricultural Productivity and Environmental Impacts: The Role of Non-parametric Analysis AgEcon
Shaik, Saleem; Perrin, Richard K..
Our contribution in this article is to compare two methods of adjusting agricultural productivity estimates for the effects of bad environmental outputs. One method is a direct non-parametric Malmquist index with the environmental variables include. The other method is to use the shadow prices from the Malmquist analysis to modify a Tornqvist-Theil with shadow shares for the environmental variables.

Understanding Spatial Welfare Impacts of a Grain Ethanol Plant AgEcon
Van Wart, Justin; Perrin, Richard K..
A changing world of increasing complexity, fluctuating prices, high energy costs and limited data necessitate creative blending of economic theory and available empirical statistics to understand the welfare impacts in a specific market. In this paper, a programming approach is used in tandem with spatial economic theory to understand the spatial welfare impacts of an ethanol plant established in an area with a beef feeding industry. The study concludes that corn transportation costs are less significant in plant pricing strategy than originally identified by other studies. Local ethanol plant competition is found to explain the lower-than-feed value pricing of ethanol byproducts at the plant. In the study, average welfare effects are calculated for...

NON-PARAMETRIC ENVIRONMENTAL ADJUSTED PRODUCTIVITY (EAP) MEASURES: NEBRASKA AGRICULTURE SECTOR AgEcon
Shaik, Saleem; Perrin, Richard K..
Traditional Total factor productivity [TFP] misrepresents the true change in agricultural productivity because environmental bads jointly produced with desirable outputs are unaccounted. Nonparametric measures incorporating environmental bads support the hypothesis that prior [after] to 1980's the traditional TFP overstate [understate] production growths, reflecting peak use of chemicals.

Sub-Saharan Africa: Methods for Examining Institutions and Agricultural Productivity AgEcon
Yu, Bingxin; Fulginiti, Lilyan E.; Perrin, Richard K..
This study estimates nonparametric non-stochastic Malmquist indices and a stochastic Fourier production frontier to examine agricultural productivity and its interactions with socio-political institutions in 41 sub-Saharan African countries during 1961-1999. We have learned from this study that on average, agricultural productivity in SSA was negative during the 1960's and 1970's, but has been positive during the last two decades. Institutions offer a significant explanation of at least some of the differential performance across countries.

AGRICULTURE PRODUCTIVITY IN SUB-SAHARAN AFRICA AgEcon
Yu, Bingxin; Fulginiti, Lilyan E.; Perrin, Richard K..
This study has estimates a Fourier flexible production frontier to examine agricultural productivity in forty-one sub-Saharan Africa (SSA) countries during 1961-1999. The primary empirical result is that only nine of these countries experienced productivity improvements, while average productivity across all counties declined at the rate of 0.57% per year.

TECHNOLOGICAL CHANGE AND WELFARE IN AN ECONOMY WITH DISTORTIONS AgEcon
Perrin, Richard K.; Fulginiti, Lilyan E..
Traditional measures of the benefits of technological change use producer prices. Consumer-oriented measures are more appropriate but they require knowledge of price impacts. They may diverge in the presence of distortions. This paper shows that in general equilibrium they are interrelated differing by the price effect of the technological change.

Economic and Marketing Efficiency Among Corn Ethanol Plants AgEcon
Sesmero, Juan P.; Perrin, Richard K.; Fulginiti, Lilyan E..
We extend data envelopment analysis (DEA) to decompose the economic efficiency of a sample of ethanol plants into internal (technical and allocative) and boundary (marketing) sources. This decomposition allows us to evaluate the channels through which different plant characteristics affect plant performance. Results show that plants are very efficient from a technical point of view. Plants with higher production volumes seem to perform better not because of economies of scale but because they can secure more favorable prices (higher marketing efficiency) and execute production plans accordingly (higher allocative efficiency). This may rationalize the increase in the size of the average plant observed in the industry in recent years despite evidence of...

INSTITUTIONS AND AGRICULTURAL PRODUCTIVITY IN SUB-SAHARA AFRICA AgEcon
Fulginiti, Lilyan E.; Perrin, Richard K.; Yu, Bingxin.
Agricultural productivity in 41 Sub-Saharan Africa (SSA) countries from 1960 to 1999 is examined by estimating a semi-nonparametric Fourier production frontier. Over the four decades the estimated rate of productivity change was 0.83% per year, although the average rate from 1985-99 was a strong 1.90% per year. Former UK colonies exhibited significantly higher productivity gains than others, while Liberia and countries that had been colonies of Portugal or Belgium exhibited net reductions in productivity. We measure a significant reduction in productivity during political conflicts and wars, and a significant increase in productivity among those countries with a measure of political rights and civil liberties.

Economic Efficiency of Ethanol Plants in the US North Central Region AgEcon
Sesmero, Juan P.; Perrin, Richard K.; Fulginiti, Lilyan E..
In this study we use data envelopment analysis to decompose the overall economic efficiency of a sample of ethanol plants into three subcomponents: technical efficiency, allocative efficiency and a new component we call marketing efficiency. The relative importance of these sources of efficiency is of particular interest given the recent history of bankruptcies, plant closings and ownership change in the industry. Results reveal that observed production units are very efficient from a technical point of view as suggested by a standard deviation of 1% in technical efficiency. However, our results also show that bigger plants tend to be more economically efficient than others. The conventional methodology would have identified this difference as coming from...

An Allais Measure of Production Sector Waste Due to Quotas AgEcon
Fulginiti, Lilyan E.; Perrin, Richard K..
This paper adapts a partial equilibrium approach of Allais and Diewert to measure the efficiency loss in the producing sector due to quotas. The measure of waste is the additional profits available for reallocation subject to constraints that the welfare of persons and firms outside the sector is unaffected. It is relevant to a sector which faces fixed prices for some commodities, but endogenous prices for others. Tobacco quotas in the United State are estimated to have caused quota-induced producer-sector waste of approximately $95 million per year during 1950-82, or about 3 percent of the average value of the crop.

Environmental Efficiency Among Corn Ethanol Plants AgEcon
Sesmero, Juan P.; Perrin, Richard K.; Fulginiti, Lilyan E..
Economic viability of the US corn ethanol industry depends on prices, technical and economic efficiency of plants and on continuation of policy support. Public policy support is tied to the environmental efficiency of plants measured as their impact on emissions of greenhouse gases. This study evaluates the environmental efficiency of seven recently constructed ethanol plants in the North Central region of the U.S., using nonparametric data envelopment analysis (DEA). The minimum level of GHG emissions feasible with the available technology is calculated for each plant and this level is used to decompose environmental efficiency into its technical and allocative sources. Results show that, on average, plants in our sample may be able to reduce GHG...

THE IMPACT OF TECHNOLOGICAL CHANGE ON A COMPETITIVE INDUSTRY AgEcon
Perrin, Richard K..
This study analytically evaluates the impact of technological change on output and input markets in a competitive industry of identical firms. Firm-level technology and technological change are represented parametrically as local approximations to unknown functional forms. The comparative statics analysis solved for changes in equilibrium market prices and quantities as functions of parameters that characterized technological change. The technology-induced shift-weighted induced change input prices. The model provides a consistent and systematic framework for evaluating the impact of technological change, either ex ante or ex post.

DYNAMIC PRICING OF GENETICALLY MODIFIED CROP TRAITS AgEcon
Perrin, Richard K.; Fulginiti, Lilyan E..
This paper considers the time path of prices for crop traits such as herbicide resistance, specifically whether they conform to Coase's conjecture that monopoly prices can't be sustained on durables. While property rights determine whether such traits are durables, prices for RR soybeans and Bt corn are consistent with Coase.

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.

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...

INTERVENTIONS AND PRODUCTION SECTOR WASTE IN LDC AGRICULTURE AgEcon
Fulginiti, Lilyan E.; Perrin, Richard K..
Recent studies have revealed that less developed countries (LDCs) have been taxing their agricultural sectors at rates of 40-50%. This study uses quantity-based general equilibrium measures of deadweight loss to evaluate the cost of these distortions in 18 of these countries. The Allais-Debreu loss measures indicate that from 7-16% of either output or of the agricultural resource base has been wasted due to the associated misallocation of agricultural inputs across these countries.
