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.

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.

An Implementable Index of Sustainability and Assessment of Energy Policy AgEcon
Sesmero, Juan P.; Fulginiti, Lilyan E..
Energy is a critical input in production and the main sources of energy in modern economies are exhaustible. Therefore sustaining aggregate consumption across generations requires reduction of the quantity of energy used per unit of output. Energy policies incentivize the deployment of new technologies that will not only increase energy efficiency but also impact the ease with which capital and materials can substitute for energy and hence the ability of societies to sustain consumption. Therefore an assessment of the impact of energy policies on sustainable consumption requires accounting for the link between technological progress and substitutability. We first allow for biased technical change and find that capital augmenting technical change (e.g....

Conservation Needs Assessment: Sustainability with Substitution and Biased Technical Change AgEcon
Sesmero, Juan P.; Fulginiti, Lilyan E..
This study explores the role of rate and biases of technological change in the sustainability of an economy with an exhaustible resource. In order to achieve this goal, the mathematical concept of viability kernel is introduced as a sustainability indicator and necessary conditions for sustainability are completely depicted in terms of technological parameters. The literature has historically assumed substitutability between human capital and natural resources and technological progress that is neutral in terms of relative input productivity and minimum efficient scale of production. Both assumptions have been widely criticized given the patterns of technological change and substitution observed empirically. Hence the theoretical contribution developed...

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.

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...

Economic and Marketing Efficiency Among Corn Ethanol Plants AgEcon
Sesmero, Juan P.; Perrik, Richard K.; Fulginiti, Lilyan E..
In the corn ethanol industry, the ability of plants to obtain favorable prices through marketing decisions is considered important for their overall economic performance. Based on a panel of surveyed of ethanol plants we extend data envelopment analysis (DEA) to decompose the economic efficiency of plants into conventional sources (technical and allocative efficiency) and a new component we call marketing efficiency. The latter measure allows us to evaluate plants’ ability to contract favorable prices of corn and ethanol relative to spot market prices and its implications for their overall economic performance. Results show that plants are very efficient from a technical point of view. Dispersion in overall economic performance observed across units is...

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...

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...

Impact of local public goods on agricultural productivity growth in the U.S. AgEcon
Sun, Ling; Ball, V. Eldon; Fulginiti, Lilyan E.; Plastina, Alejandro S..
In this paper we revisit the issue on the impact of public R&D expenditure on US agricultural productivity growth. We estimate a dual cost function using a state-by-year panel data set. We construct the potential R&D “spillins” based on both geographical location and production mix. We also examine the role of the extension service, transportation network, and human capital in the process of technology dissemination. The results indicate that higher levels of local public goods, R&D spillins, extension activities, and an intensive transportation network decrease costs. The contributions to agricultural productivity from all series of R&D spillins are positive even though the social rate of return may differ.

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.

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.

Investing in Hope: AIDS, Life Expectancy, and Human Capital Accumulation AgEcon
Huang, Rui; Fulginiti, Lilyan E.; Peterson, E. Wesley F..
A three period overlapping generations model is developed to investigate the impact of shorter life expectancy due to disease, on human capital investment decisions and income growth. This research is particularly relevant to Sub-Saharan Africa given the dramatic reduction in life expectancy due to HIV/AIDS and the potential lasting effects on growth. Our results indicate that as life expectancy shortens so does schooling inducing a lower growth rate of income. These relationships are even more pronounced for the African continent than for the rest of the world.

PRICE-CONDITIONAL TECHNOLOGY AgEcon
Fulginiti, Lilyan E..
Economics theorists for years have considered the possibility that the direction of technical change is altered by changes in relative prices. Prices also have been identified as one of the determinants of technical change through innovation. This article extends the theory of the firm to cover situations in which the firm’s' technology set is conditional on expected prices. The basic idea is to distinguish between “"market prices,"” or the prices that guide the firm’s choices subject to the technology that is in place, and “"normal prices,"” the prices conditioning the choice of technology. A “"generalized”" price effect is obtained that included the traditional price effect as well as the technical change effect of price changes, and an example is...
