THE IMPACT OF LIFE EXPECTANCY IN HUMAN CAPITAL ACCUMULATION: AIDS 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.

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.

Public Inputs and Endogenous Growth in the Agricultural Sector: a Dynamic Dual Approach AgEcon
Onofri, Alejandro; Fulginiti, Lilyan E..
This paper examines growth in the U.S. agricultural sector under the conditions hypothesized by endogenous growth theory. Public capital and R&D are explicitly considered to capture the effects of public inputs in a model based on dynamic duality theory. Results support some necessary conditions for this hypothesis to be true.

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.

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...

Rates of Return to Public Agricultural Research in 48 U.S. States AgEcon
Plastina, Alejandro S.; Fulginiti, Lilyan E..
The internal rate of return to public investment in agricultural R&D is estimated for each of the continental U.S. states. Theoretically, our contribution provides a way of obtaining the returns to a local public good using Rothbart’s concept of virtual prices. Empirically, we use the spatial dependency among states generated by knowledge spillovers to define the ‘appropriate’ jurisdiction. We estimate an average own-state rate of 17% and a social rate of 27%. These figures should inform the policy debate on the allocation of federal funds to research in anticipation of a possible global food crisis.

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...

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.

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.

TECHNOLOGY, FACTOR ENDOWMENT, PRICES AND THE RELATIVE DECLINE OF AGRICULTURE IN TAIWAN AgEcon
Sun, Ling; Fulginiti, Lilyan E.; Peterson, E. Wesley F..
This paper specifies an empirical model of the relative decline of the agricultural sector consistent with the neoclassical explanation. We utilize a production theory approach to analyze the effect of changes in relative prices, relative factor endowments and technical change on the share of agriculture in GDP in a growing economy. The model is estimated with time series data on the agricultural sector and nonagricultural sectors in Taiwan.

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...

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.
