A JOINT LIVESTOCK-CROP MULTI-FACTOR RELATIVE PRODUCTIVITY APPROACH AgEcon
Jones, Keithly G.; Arnade, Carlos Anthony.
An output distance function conditional on the expansion of a second output is presented. These distance functions are used to calculate distinct relative Total Factor Productivity (TFP) scores for two jointly produced products-livestock and crops for 27 countries. From these, TFP growth and direction of growth are calculated.

A METHOD FOR COMPARISON OF THE EFFICIENCY OF COUNTRIES WITH DISTINCT TECHNOLOGIES AgEcon
Arnade, Carlos Anthony; Jones, Keithly G..
We divide countries into two technology categories: developed and developing. Agricultural efficiency within each technology category was calculated. Cross-category efficiency measures were developed and combined with own-category measures to develop a technical difference index. Results indicate convergence of efficiency within both categories but divergence of efficiency between the two categories.

AN ASSESSMENT OF DYNAMIC BEHAVIOR IN THE U.S. CATFISH MARKET: AN APPLICATION OF THE GENERALIZED DYNAMIC ROTTERDAM MODEL AgEcon
Muhammad, Andrew; Jones, Keithly G..
Dynamic demand systems have been employed in a number of studies to account for habit formation and inventory adjustments in demand. Few studies have attempted to provide a theoretical foundation for the dynamic demand structures employed. Recently, Bushehri (2003) showed how a generalized dynamic Rotterdam model could be derived from the neoclassical intertemporal utility maximization problem; however, no empirical application is provided in his study. This paper provides an empirical application of the generalized dynamic Rotterdam model to the demand for processed catfish products in the U.S. The two-period dynamic Rotterdam model explained a significant amount of the variation in U.S. catfish demand and was preferred to the one-period and static...

An Assessment of Dynamic Behavior in the U.S. Catfish Market: An Application of the Generalized Dynamic Rotterdam Model AgEcon
Muhammad, Andrew; Jones, Keithly G..
The generalized dynamic Rotterdam model was used in estimating U.S. demand for disaggregated catfish. The overall goal was to examine habit persistence in consumption and to determine the adjustment process in demand. Results indicated that it took up to 1 month for catfish-product demand to fully adjust to changes in expenditures and prices. Additionally, habit persistence played a role in demand where present consumption of a given product was positively affected by past consumption of that product. Consequently, U.S. catfish demand was significantly more elastic in the long-run.

Country of Origin Labeling: Evaluating the Impacts on U.S. and World Markets AgEcon
Jones, Keithly G.; Somwaru, Agapi; Whitaker, James B..
A provision of the Food, Conservation, and Energy Act of 2008 requires country of origin labeling (COOL) for certain agricultural commodities. To comply with the law, producers, processors, and retailers face additional production costs associated with labeling, separating, and tracking commodities. Using estimated costs provided by the U.S. Department of Agriculture’s Agricultural Marketing Service (AMS), we simulate the impacts of mandatory COOL on U.S. and global agricultural markets using a global static general equilibrium model (STAGEM). The results show resource adjustments that lead to decreases in production, consumption, and trade flows. The results assume no demand premium for labeled commodities relative to unlabeled commodities.

Demand for U.S. Lamb and Mutton: A Two Stage Differential Approach AgEcon
Jones, Keithly G.; Hahn, William F.; Davis, Christopher G..
Estimates of price and scale demand elasticities for lamb and mutton consumed in the United States are derived. The U.S. lamb and mutton consumption comprises primarily of domestic production, and imports from two countries-Australia and New Zealand. The Netherlands Central Bureau of Statistics (CBS) demand system derived by Keller and Van Driel (1985) is employed. The CBS model is preferred as it combines non-linear Engel curves with the simplicity of the Slutsky matrix and allows for the ease of implementing concavity and other restrictions. Empirical results for own-price elasticities of demand indicate that U.S. demand for Australian lamb demand is highly elastic while U.S. demand for New Zealand and domestic lamb was inelastic. The scale demand...

Derived Demand for Cattle Feeding Inputs AgEcon
Mathews, Kenneth H., Jr.; Arnade, Carlos Anthony; Jones, Keithly G..
Derived demand relationships among four weight categories of feeder cattle entering Texas feedlots and their feed consumed are examined using a generalized McFadden dual cost function. Results demonstrate systematic differences in demand relationships among different weight categories. Positive cross-price elasticities among the three heaviest weight categories are consistent with input substitution among weight categories and consistent with objective functions associated with optimal placement weight. Anomalies in the form of negative cross-price elasticities between weight categories provide evidence for an alternative objective function associated with longer term feeding of light-weight feeder cattle. Results also demonstrate seasonality differences...

Derived Demand for Cattle Feeding Inputs AgEcon
Arnade, Carlos Anthony; Mathews, Kenneth H., Jr.; Jones, Keithly G..
Derived demand relationships among four weight categories of feeder cattle entering Texas feedlots and feed were examined using a Generalized McFadden dual cost function specified as an error correction model. Relationships among own- and cross-price elasticities provide evidence for at least two cattle feeding enterprises, feeding lightweight feeder cattle (calves) and feeding heavier cattle. These results indicate systematic differences in demand relationships among the different weight classes, providing explanation and insight into mixed results from earlier studies. Seasonality differed across weight categories, providing additional support for multiple cattle feeding enterprises. A third step was added to the Engle-Granger two-step estimation...

Evaluating the Economic Impact of Countervailing Duties on United States Warm Water Shrimp Imports AgEcon
Jones, Keithly G.; Harvey, David J..
Estimates of price and scale elasticities for U.S. consumed shrimp are derived using aggregate source country shrimp import data. It was assumed that supply was perfectly elastic and U.S. wholesalers determine the quantities imported from individual countries given the prices and preferences of U.S. consumers. Ex-ante analysis suggests that most countries levied with the countervailing duty experience declines in U.S. import demand while those countries not affected by the countervailing duty experience increases in import demand. Ex-post analysis shows the reverse to be true. Several countries impacted by the countervailing duty had increased import demand from the United States while Mexico, which was not affected by the countervailing duty, had...

Levels or Differences in Meat Demand Specification AgEcon
Hahn, William F.; Jones, Keithly G.; Davis, Christopher G..
We estimated a wholesale demand system for beef, pork, lamb, chicken, and turkey using quarterly U.S. data and a dynamic, CBS system (Keller and Van Driel). The CBS system is a differential system, which means that it might be more appropriately applied in those situations where the data have unit roots. If there are unit roots, differencing the data can improve the properties of the estimates. If the data do not have unit roots, differencing the data might harm the properties of the estimates. We tested the specification of the model's error terms using state-space techniques. State-space units allow one to deal with roots on the unit circle without filtering the data (See Durbin and Koopman). The demand system has only four independent error...

Market Integration for Shrimp and the Effect of Catastrophic Events AgEcon
Harri, Ardian; Muhammad, Andrew; Jones, Keithly G..
Seasonal unit-root testing and seasonal cointegration methods are employed to investigate the price transmission in U.S. shrimp markets. ARIMA and Vector Error Correction Models (VECM) are used to identify the effect of catastrophic events on individual price series in one region and the spillover effects in the price series for other regions. Results showed that a cointegrating relation exists between neighboring states, specifically between Alabama and Mississippi and Louisiana and Texas. Cointegrating relations also exist between the Gulf States and the Pacific region, but not the Atlantic region, and the price of imported shrimp is cointegrated with each of the domestic shrimp price series. Finally, while Katrina had an effect on shrimp prices in Gulf...

Modeling the Cattle Replacement Decisions AgEcon
Arnade, Carlos Anthony; Jones, Keithly G..
In this paper we evaluate the performance of a dynamic model of cattle replacement and culling decisions. We derive the price of cattle when it is treated as a unit of capital and evaluate various rates of adjustment of the cattle herd to determine the length of the cattle cycle. Replacement decision is modeled as the solution to a dynamic optimization problem where the breeding herd is viewed as a capital asset that is capable of producing two outputs: calves and culled cows. The own-price, replacement and interest rate elasticities calculated for both the short-run and long-run time-frames suggest fairly rapid adjustment rates. Tests of cycle length revealed a 14-year cattle cycle.

Price Volatility and Transmission in the Hog and Pork Markets AgEcon
Jones, Keithly G..
Farm, wholesale and retail price relationships for U.S. hogs are analyzed. Price transmission estimates indicate partial adjustment in each market category when price changes in any other market. This implies imperfect price transmission between the market levels. Tests of Granger no-causality show causality in hog and pork markets.

The Effect of Relative Prices and Exchange Rates on Domestic Market Share of U.S. Red-Meat Utilization AgEcon
Jones, Keithly G..
Trade-related factors influencing the decline in domestic market share of U.S. red meats were investigated. The study are to examine the effects of relative meat price changes (domestic and imported), the relative U.S. dollar values and their volatilities, and the effect that BSE has had on U.S. red-meat trade. The results show that the relative meat price and exchange rate indices as well as their volatilities significantly affect the U.S. market share of its total meat utilization. The BSE dummy variable has an expected positive sign, though it was statistically insignificant.

The Impact of Catfish Imports on the U.S. Wholesale and Farm Sectors AgEcon
Muhammad, Andrew; Neal, Sammy J.; Hanson, Terrill R.; Jones, Keithly G..
The primary objective of this study was to assess the impact of catfish imports and tariffs on the U.S. catfish industry, with particular focus on the U.S. International Trade Commission ruling on Vietnam in 2003. Given the importance of Vietnam to the U.S. catfish market, it was assumed that catfish import prices would increase by 35 percent if the maximum tariff was imposed on catfish from Vietnam. With the tariff, domestic catfish prices at the wholesale level would increase by $0.06 per lb, and farm prices by $0.03 per lb. Processor sales would increase by 1.66 percent. Total welfare at the wholesale level would increase from $69.2 million to $71.7 million, an increase of about 3.63 percent, and processor and farm revenue would increase by 4.4 percent...

The Impact of Domestic and Import Prices on U.S. Lamb Imports: A Production System Approach AgEcon
Muhammad, Andrew; Jones, Keithly G.; Hahn, William F..
As U.S. lamb imports increased relative to domestic production, and the relative share of chilled to frozen lamb imports increased, importers of chilled lamb have become less responsive to domestic and import prices, while the direct opposite is the case for frozen lamb imports. From 1990 to 2003, chilled lamb imports from Australia and New Zealand became less and less responsive to U.S. prices, and frozen imports became more responsive. Unconditional own-price elasticities also show that, over time, imports of chilled lamb became less responsive to import prices while frozen imports became more responsive to import prices.

Trends in the U.S. Sheep Industry AgEcon
Jones, Keithly G..
The U.S. sheep industry has changed greatly since the end of World War II. Both sheep meat and wool production have seen rapid declines. So, too, have revenues and the number of sheep operations. The wool industry has suffered from increased use of synthetic fivers, which were found to be less expensive than wool and, when blended with natural fibers, more attractive to consumers. Historically, lamb meat was a byproduct of the wool industry, but wool's decline has changed that. Lamb meat production became the emphasis of the sheep industry, but lamb prices have been unable to support a recovery in the sheep industry. U.S. lamb production continues to decline, but with lamb meat imports filling in, expansion and diversification of demand for this meat...
