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.
America's Forgotten People and Places: Ending the Legacy of Poverty in the Rural South: Discussion [статья]
Опубликовано на портале: 24-11-2003Ntam Baharanyi, Robert Zabawa, Evelyn Boateng Journal of Agricultural and Applied Economics. 2000. Vol. 32. No. 2. P. 357-361.
These comments discuss the presentations by Christy, Wenner, and Dassie ("A Microenterprise- Centered Economic Development Strategy for the Rural South: Sustaining Growth with Economic Opportunity") and Freshwater ("What Can Social Scientists Contribute to the Challenges of Rural Economic Development?") in three sections. These are a brief overview of the Southern Black Belt and its rural development needs, an assessment of the microenterprise-centered economic development strategy for the rural South, and a quick review of what social scientists can contribute to the challenges of rural economic development. This approach also emphasizes the authors' background at a historically black land-grant university, and the belief that as goes the Black Belt, so goes the rural South.
An Evaluation of the Effectiveness of the Florida Cooperative’s Seasonal Pricing Plan on Seasonal Production Variability [статья]

From 1993–1995, Florida dairy cooperatives implemented a seasonal pricing plan in an attempt to decrease the variability in seasonal production, Farmers that participated in the seasonal pricing plan were able to reduce seasonality in each year when compared to 1992 by as much as 20 percent. For farmers that did not participate, seasonality increased in each year by as much as 32 percent. Overall, the seasonal pricing plan was effective in reducing seasonality for those farmers that chose to participate in the plan and that its limited short-run success was the result of seasonality increases by non-participating farms.

Two methods were used to estimate the cost of forward contracting hard red winter wheat. One hundred days before delivery, the estimated cost of forward contracting ranged from six cents/bu to eight cents/bu. Thus, further evidence is provided that the cost of forward contracting grain is not zero.
Factors Affecting Adoption of Improved Maize Seeds and Use of Inorganic Fertilizer for Maize Production in the Intermediate and Lowland Zones of Tanzania [статья]
Опубликовано на портале: 24-11-2003Aloyce R.M. Kaliba, Hugo Verkuijl, Wilfred Mwangi Journal of Agricultural and Applied Economics. 2000. Vol. 32. No. 1. P. 35-47.
This paper examines factors influencing the adoption of improved maize seeds and the use of inorganic fertilizer for maize production by farmers in the intermediate and lowland zones of Tanzania. The results indicate that availability of extension services, on-farm field trials, variety characteristics and rainfall were the most important factors that influenced the extent of adopting improved maize seeds and the use of inorganic fertilizer for maize production. Farmers preferred those varieties which minimize field loss rather than maximizing yields. Future research and extension policies should emphasize farmer participation in the research process and on-farm field trials for varietal evaluation and demonstration purposes.

Cattle producers and beef packers need to understandbasis determinantsas they develop price expectations and make pricing, hedging, and forward contracting decisions. This study empirically estimated factors explaining variability in monthly fed cattle basis. The five main results regarding live cattle basis are 1) corn price is an importantdeterminant, 2) a change in the value of the Choice-to-Select spreadpositively affects basis, 3) changes in the levels of captive supplies have no significant statisticalor economic impact on basis, 4) the June 1995 live cattle futures contract did not impact basis, and 5) both market fundamentalsand seasonal components are importantbasis determinants

Changes in consumer demand for poultry meats can be characterized as evolving over time and following seasonal patterns. The focus of this study is on understanding factors affecting wholesale poultry prices. This information is needed so that poultry processors and poultry producers may better understand how consumer purchasing patterns affect price changes. Results suggest that seasonal differences between the price of cuts exist. Furthermore, own-cut and cross-cut flexibilities were unique to individual cuts

An adaptive regression model is employed for estimating pre- and post-boll weevil eradication cotton-acreage response. Results indicate cotton acreage becoming more inelastic to own- and cross-price changes. As a result of this shift in acreage response and yield increases from eradication, net producer benefits on average are $88.73 per acre.
Incentive-Based Solutions to Agricultural Environmental Problems: Recent Developments in Theory and Practice [статья]

Theory predicts that incentive-based regulatory instruments reduce compliance costs by encouraging efficient resource allocation and innovation in environmental technology. Cost reductions from pollution permit trading often have exceeded expectations, but the devil is in the details: the rules matter. In recent years, IB instruments of many kinds, from permit trading to various informal voluntary agreements, have been introduced in many countries. Point-nonpoint trading programs have been established in the U.S., but recorded trades have been rare. We speculate about prospects for performance-based monitoring of agricultural nonpoint pollution which, we believe, would encourage trading to the benefit of farmers and society.
Incorporation of Within-Season Yield Growth into a Mathematical Programming Sugarcane Harvest Scheduling Model [статья]
Опубликовано на портале: 24-11-2003Michael E. Salassi, Lonnie P. Champagne, Benjamin L. Legendre Journal of Agricultural and Applied Economics. 2000. Vol. 32. No. 3. P. 507-519.
This study focuses on the development of a optimal harvest scheduling mathematical programming model which incorporates within-season changes in perennial crop yields. Daily crop yield prediction models are estimated econometrically for major commercially grown sugarcane cultivars. This information is incorporated into a farm-level harvest scheduling linear programming model. The harvest scheduling model solves for an optimal daily harvest schedule which maximizes whole farm net returns above harvesting costs. Model results are compared for a commercial sugarcane farm in Louisiana.

The objective is to analyze the effects of country- and firm-specific factors on the return on equity in the beverage and tobacco and food and consumer-products industries for 11 industrialized nations. The results indicate that country- and firm-specific factors are important in explaining variation in return on equity within countries but not generally across countries or time.

An expected-utility model and a chance-constrained linear programming model were used to analyze four marketing strategies and seven crop insurance alternatives for cotton marketing in Georgia. The results suggest that existing marketing tools and insurance alternatives can be used to reduce cotton producers’ revenue risk. The optimal level of yield and price insurance coverage depends on an individual producer’s risk aversion.

A differential approach is employed to analyze demand for meat in the United Kingdom during 1989–99. Differential demand systems with fixed price effects (Rotterdam and CBS) better explain consumers’ retail purchase allocation decisions for beef, lamb, pork, bacon and poultry compared with models containing variable price effects (NBR and differential AIDS). The real expenditure and the Hicksian demand elasticities are generally found to be quite different from earlier studies using AIDS models. A quality change index of meat consumption is constructed from the estimated CBS model estimation results and decomposed into real expenditure, substitution, trend, seasonal and residual effects.
Non-Parametric and Semi-Parametric Techniques for Modeling and Simulating Correlated, Non-Normal Price and Yield Distributions: Applications to Risk Analysis in Kansas Agriculture [статья]
Опубликовано на портале: 24-11-2003Allen M. Featherstone, Terry L. Kastens Journal of Agricultural and Applied Economics. 2000. Vol. 32. No. 2. P. 267-281.
Parametric, non-parametric, and semi-parametric approaches are commonly used for modeling correlated distributions. Semi-parametric and non-parametric approaches are used to examine the risk situation for Kansas agriculture. Results from the model indicate that 2000 will be another difficult year for Kansas farmers, although crop income will increase slightly from 1999. However, unless another supplemental infusion of government payments occurs, crop income is expected to be the lowest since 1992.
Parametric Modeling and Simulation of Joint Price-Production Distributions under Non-Normality, Autocorrelation and Heteroscedasticity: A Tool for Assessing Risk in Agriculture [статья]

This study presents a way to parametrically model and simulate multivariate distributions under potential non-normality, autocorrelation and heteroscedasticity and illustrates its application to agricultural risk analysis. Specifically, the joint probability distribution (pdf) for West Texas irrigated cotton, corn, sorghum, and wheat production and prices is estimated and applied to evaluate the changes in the risk and returns of agricultural production in the region resulting from observed and predicted price and production trends. The estimated pdf allows for time trends on the mean and the variance and varying degrees of autocorrelation and non-normality (kurtosis and right- or left-skewness) in each of the price and production variables. It also allows for any possible price-price, production-production, or price-production correlation.
