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.

Market and Welfare Effects of GMO Introduction in Small Exporting Countries AgEcon
Plastina, Alejandro S.; Giannakas, Konstantinos.
This paper analyzes the market and welfare effects of the introduction of GM products in small open developing economies that, prior to the adoption of GM crops, were net exporters of non-GM products. It explicitly accounts for differences in consumer attitudes towards GM products and producer agronomic characteristics as well as for the structure and conduct of the GM seed suppliers. Different scenarios concerning different labeling regimes in the small exporting country and the world market of the products are considered. A positive welfare effect of the introduction of GM products to small open economies should not be taken for granted. While yield increases and cost reductions associated with the GM technology are certainly important, their presence...

Market and Welfare Effects of Mandatory Country-of-Origin Labeling in the US Specialty Crops Sector AgEcon
Plastina, Alejandro S.; Giannakas, Konstantinos; Pick, Daniel H..
This study provides a new framework of analysis of the market and welfare effects of mandatory country of origin labeling (MCOOL) for fruits and vegetables that accounts for heterogeneous consumer preferences for domestic products, differences in producer agronomic characteristics, and retailer market power when buying and selling these products. The market and welfare effects of MCOOL are shown to be case-specific and dependent on the labeling costs at the farm and retail levels, the strength of consumer preference for domestic products, the market power of retailers, the marketing margin along the supply chain, and the relative costs of imported and domestic products. Simulation results for the US markets of apples and tomatoes indicate that for the...

PASS-THROUGH ANALYSIS OF COTTON PRICES AgEcon
Devine, Jon; Plastina, Alejandro S..
A common question when analyzing supply chains is how much a change in input costs at one stage in the supply chain affect prices downstream. To address this question, research has been conducted that examines the extent that changes in prices are “passed-through.” Much of the pass-through research that has been conducted has been focused on changes in prices at the beginning of supply chains - at the commodity-level. To date, however, there is no known research analyzing the effect of changes of cotton fiber prices on cotton textile goods, neither at different stages in the cotton supply chain, nor at the retail level. While pass-through analysis of the cotton supply chain presents certain challenges in terms of data collection, it also presents great...

Rates of Return to Public Agricultural Research in 48 U.S. States AgEcon
Plastina, Alejandro S.; Fulginiti, Lilyan E..
The present study provides a quantitative assessment of the benefits from public agricultural research and development (R&D) for each continental state of the U.S. for 1949-1991, explicitly acknowledging for spillover effects. The novelty of this study resides in the use of spatial econometric techniques to account for stochastic spatial dependency generated by knowledge spillovers. The estimated national average own state internal rate of return (IRR) to investments in public agricultural R&D is 15.69%; while the estimated national average social IRR is 27%. Failing to account for the indirect effects of knowledge spillovers results in estimates that are, on average, 11% and 13% higher.

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.
