Atlanta is a relatively large market for goat meat. As in most metropolitan areas around the U.S., goat-meat consumption has grown steadily in Atlanta over the past decade (Northwest Cooperative Development Center 2005; Nettles and Bukenya 2004). This growth is attributed to the influx of immigrants from goat-meat-eating countries into the U.S. over the same period (Gipson 1999). The increase in demand for goat meat has made the U.S. a net importer of competitively priced goat meat from Australia and New Zealand into major U.S cities such as Atlanta (USDA-FAS 2006). The fact that goat-meat imports from Australia have steadily increased over the years makes markets such as Atlanta of particular interest to both Georgia goat-meat suppliers and meat-goat...

Food Expenditures in Rural Households in the Northern Region of Ghana

Meng, Ting; Florkowski, Wojciech J.; Kolavalli, Shashidhara; Ibrahim, Mohammed.

The objective of the paper is to identify farmer and farm characteristics that determine the food expenditure in rural households in the Northern Region of Ghana. The results indicate income, implicit wealth, age, family structure, cultivation staple or cash crop, and buying dry goods in bulks are the major determinants.

Forecasting Price Relationships among U.S Tree Nuts Prices

This paper investigates a vector auto regression model, using the Johansen cointegration technique, and the autoregressive integrated moving average time series models to determine the better model for forecasting US tree nut prices over the period 1992-2006. The Johansen contegration test shows lack of long run relationship among pecan, walnut, and almond prices. As such, only autoregressive integrated moving average-type models were used in forecasting U.S. nut prices.

Forecasting U.S. Shelled Pecan Prices: A Cointegration Approach

The relationship between shelled pecan prices and inventories is examined drawing using Engle-Granger and Johansen approaches to cointegration. Forecasts are made using the univariate ARIMA and cointegration methods. Monthly data are used (January 1992 to December 2004). Results suggest that both shelled pecan inventories and shelled pecan prices are nonstationary. Both Engle-Granger and Johansen cointegration tests found evidence of long run relationship between pecan prices and inventories. The ARIMA model outperformed the coointegration techniques at shorter forecast periods. The Cointegration methods, however, outperformed the ARIMA model with the Engle-Granger cointegration having the smallest MAPE statistic.

Although most U.S. tree nuts have very specific and different uses, some substitutability does occur, complicating the price analysis in the tree nut market. We examine the relationships among U.S. tree nut prices using the Johansens cointegration procedure. We found long run equilibrium among some nut prices, namely, pecans, walnuts, and almonds. These findings are consistent with recent suggestions that cointegration exist among substitutes.

Student Response to Transgenic Meat: An analysis of a Fort Valley State University Survey

The study examines the factors the factors that influence Fort Valley State University students’ willing to purchase transgenic meat. Results show that respondents who said they read labels when shopping were more likely to purchase transgenic meat. Results also suggest that respondents who trust scientists to tell them the truth about transgenic meat were more likely to purchase transgenic meat. Respondents who identified themselves as sophomores, however, were less likely to consume transgenic meat.

Using time series data we examine behavior of pecan prices and inventories at zero and seasonal frequencies, given results of seasonal cointegration tests. Both, seasonally unadjusted and adjusted quarterly data are used (1991-2002). Results suggest that, first, shelled and total pecan inventories and shelled pecan prices have common unit roots at both the non-seasonal and seasonal frequencies; second, there is no long run equilibrium between pecan prices and shelled or total inventories when unadjusted data are used. Finally, the speed of adjustments suggests pecan prices adjust to shocks in inventories and not the vice versa.

The Value of Information in Precision Farming

This study examines how the value of information is measured and its role in precision farming. Two types of precision farming are discussed regarding information in use and ways of information collection. Analytical equations have been derived to link the estimation of the value of information to limited parameters available.

Will Consumers Pay a Premium for Clone-free labeled Meat products? Evidence from the 2009 Sunbelt Agricultural Exposition

This paper examines consumer willingness to pay (WTP) for clone-free meat labels. Data were collected at the Sunbelt Agricultural Exposition (Ag Expo) in Moultrie, Georgia using a consumer survey instrument. Survey results show that majority (59.45%) of the respondents said they were willing to pay for clone-free labels. Results suggest that bid amount, gender and education are factors that influence WTP for clone-free labels.
