This address is directed toward applied economists as they provide information to private and public decision makers, Central to this discussion is the role of markets as institutions in achieving society’s desired ends. Current “economic correctness’’--the view that unfettered markets are superior in achieving efficiency, growth, and welfare--has attempted to return a larger role to the private sector, but the relative roles of market-oriented versus government-oriented solutions to problems are often not well appraised. Views presented herein calls for agricultural economists to move simultaneously toward an understanding of the strategic behavior of firms in imperfectly competitive markets and toward an adoption of policy analysis consistent with a socially complex and globally integrated economy.

The impact of hypothetical changes in yields, costs, and demand that might result from the organization of Oklahoma vegetable growers into cooperatives or other multifarmer marketing associations is estimated using a sector programming model. A comparative static analysis is used to evaluate the impact of these changes on planted acreage, growers’ revenues, and consumers’ and producers’ surplus. The results of this analysis indicate that changes in demand are most effective in increasing revenues for Oklahoma growers.

Price and expenditure elasticities at retail level for 11 fresh fruits and 10 fresh vegetables were estimated by employing a composite demand system approach and using annual data. Most fresh fruits and vegetables were found to respond significantly to changes in their own prices but insignificantly to changes in total expenditures. The demand for fresh fruit group appeared to have had a clear upward trend since 1973. However, no significant trends were found in the demands for individual fresh fruits or vegetables. The study partially incorporated the interdependent demand relationships between fresh fruits (vegetables) and all other commodities, yet effectively avoided the problem of insufficient degrees of freedom.

Attributes for two value-added seafood products derived from underutilized crawfish are analyzed using conjoint data from seafood restaurants in the southern region of the United States. Preferences for the products’ form, price, and flavor attributes were tested. Statistical tests revealed that the attribute interactions were not significant, and part-worth utilities for all main effects were estimated using an additive preference model. Results indicate that the new crawfish products should be marketed as a high-quality fresh soup base or seafood stuffing, priced between 30% and 50% of the cost of fresh crawfish tail meat.

Conjoint valuation approach analysis, widely used in marketing research, offers an alternative resource suited to outdoor recreation activities characterized as multiattribute. Design, implementation, and interpretation of conjoint analysis are reviewed in the context of recreation applications. Conjoint analysis is used in an analysis of waterfowl hunting in Louisiana. Using primary data collected from a survey of waterfowl hunters, ordered logit is used to estimate willingness-to-pay for recreation experience attributes.

An expected utility model that includes output price and yield uncertainly was used to estimate cotton, corn, and soybean acreage response equations for the Southeast. The model appeared to fit the soybean and corn data well, resulting in own-price elasticity estimates of 0.317 for com and 0.727 for soybeans. When applied to cotton acreage, however, the model did not yield satisfactory results. When elasticity was allowed to changeover time, however, statistical results for the cotton equation improved, yielding an own-price elasticity of 0.915 at data means.
A Cross-Section Analysis of Intra-industry Trade in the U.S. Processed Food and Beverage Sectors [статья]
Опубликовано на портале: 24-02-2005Darcy A. Hartman, Dennis R. Henderson, Ian M. Sheldon Journal of Food Distribution Research. 1993. Vol. 24. No. 1.
This paper analyzes the determinants of variation across industries in levels of intraindustry trade (IIT) for a sample of 36 U.S. processed food and beverage industries in 1987, previous studies of intra-industry trade having focussed on industry characteristics in the manufacturing sectors. The determinants predicted by IIT theory are measures of product differentiation, economies of scale, and imperfect competition; the results of this analysis indicate that IIT variation across the food and beverage industries is positively related to product differentiation, U.S. total trade, similarity of tariff barriers among trade partners, and economies of scope, but negatively related to industry concentration.
Actuarial Effects of Unit Structure in the U.S. Actual Production History Crop Insurance Program [статья]
Опубликовано на портале: 24-11-2003Thomas O. Knight, Keith H. Coble Journal of Agricultural and Applied Economics. 1999. Vol. 31. No. 3. P. 519-535.
This paper examines the effects of optional subdivision on APHP losses for wheat, corn, and soybeans. Thirty-seven state/crop programs are analyzed and the implications of the results are discussed in relation to newly developed crop and revenue insurance programs. The results illustrate the importance of incorporating actuarial experience into the premium rate structure and contract provisions of an insurance program.

The beef cattle investment decision provides an excellent opportunity to increase the economic efficiency of beef cattle production. The investment questions that face beef cattle producers are of interest to beef cattle producers, educators, and financial institutions involved in lending to beef cattle producing firms. This study develops a decision support aid utilizing expert system technology to assist beef cattle producers in making well-founded investment decisions with respect to the firm’s beef cattle herd.
Adult Equivalence Scales Revisited [статья]
Опубликовано на портале: 21-11-2003Michael Demoussis, Vassilis Mihalopoulos Journal of Agricultural and Applied Economics. 2001. Vol. 33. No. 1.
Use of the Tobit model for estimation of adult equivalent scale (AES) parameters and expenditure equations presupposes that zero observations represent exclusively corner solutions. This paper tests for the underlying causes of zero observations and estimates accordingly the AES parameters, the household size in adult equivalents and the resulting expenditure equations and consumption profiles. The empirical application concerns Greek household “soft” and “hard” cheese consumption. The statistical results indicate that for the examined cheese categories the “double hurdle participation” model adjusted for non-normality and heteroskedasticity is the appropriate model for the estimation of AES parameters.
A Dynamic Analysis of the Impact of Water Quality Policies on Irrigation Investment and Crop Choice Decisions [статья]
Опубликовано на портале: 17-02-2005JunJie Wu, Harry P. Mapp, Daniel J. Bernardo Journal of Agricultural and Applied Economics. 1994. Vol. 26. No. 2. P. 506-525.
A dynamic model is developed to analyze farmers’ irrigation investment and crop choice decisions under alternative water quality protection policies. The model is applied to an empirical example in the Oklahoma High Plains. The choices of crops and irrigation systems and the resulting levels of irrigation, income, and nitrogen runoff and percolation are simulated over a ten year period. An effluent tax on nitrogen runoff and percolation is shown to be effective in reducing nitrate pollution, The efficacy of cost sharing in adopting modern irrigation technologies and restrictions on irrigation water use depends on soil type. A tax on nitrogen use IS shown to be the least effective policy.
Aggregate Food Demand Analysis For A Transitional Economy: An Application to Chinese Household Expenditure Data [статья]
Опубликовано на портале: 09-03-2005Hongqi Shi, Ron C. Mittelhammer, Thomas I. Wahl Journal of Food Distribution Research. 1995. Vol. 26. No. 2. P. 20-27.
An analytical framework to assess the effects of changing income and socio-demographic distributions on aggregate food demand functions in transitional economies is presented. Ignoring such distributional effects can lead to biased estimates of aggregate demand elasticities. The proposed method is applied to Chinese urban household expenditure survey data. The results indicate that the drastic distributional changes that have occurred in China have had notable effects on estimated demand elasticities for both food and non-food commodity groups.

The Agricultural Economics profession has been using computer technology in their research, extension and teaching program for over three decades. However, commonly accepted nomenclature for the types and levels of computer skills required of students by agribusiness employers has not been developed. This paper provides a framework for agricultural economics and agribusiness instructors to both plan and evaluate the type and levels of computer skills being taught to graduates of their program.

Growers and community leaders have expressed interest in establishing a horticultural shipping-point market in Southwest Virginia. This paper reports on a study that assessed whether horticultural production would be profitable in the region and, if so, the physical and organizational requirements for a successful shipping-point market. It appears that tomatoes, peppers, and pumpkins can be produced and marketed profitably to large-volume wholesale buyers if growers meet the exacting requirements of the retailers. A cooperative association is the organizational structure with the greatest chance of success. At the conclusion of this study, a shipping-point market in the recommended form was established in Southwest Virginia.

It is appropriate as we enter a new century that we reflect on the past one since our profession is nearly 100 years old: the American Association of Farm Economics was formally created in 1910. "Savvy through one hundred years of progress and experience" is one description that comes to mind. "Geriatric" is another word that might fit. I intend to highlight some broad topics that have occupied agricultural economists' teaching and research over the past 100 years, to reflect in a little more detail about our thoughts over the past 12 years as revealed in the presidential addresses at AAEA and SAEA annual meetings, to make some rather terse comments about current important issues as they relate to the issues of the past, and to conclude with some advice for the younger members of our profession and our association that may be of value in the new century. I emphasize the word may, because I am much less certain about the wisdom of my beliefs today than if I had been given the opportunity to give this talk 18 or even 11 years ago.
