AN ECONOMIC ANALYSIS OF A FOOD SECURITY COMMODITY RESERVE: COMMODITY VS. CASH 31
Young, C. Edwin; Westcott, Paul C.; Hoffman, Linwood A.; Lin, William W.; Rosen, Stacey L..
The cost of operating the Food Security Commodity Reserve as a commodity reserve was compared with the cost of a cash reserve to purchase food aid supplies only in the period of need. Preliminary simulation results reveal the cash reserve to be less costly in almost all cases.

Domestic Support for the U.S. Rice Sector and the WTO: Implications of the 2002 Farm Act 31
Hoffman, Linwood A.; Young, C. Edwin; Westcott, Paul C.; Childs, Nathan W..
The U.S. rice sector is expected to receive some of the largest relative support under the 2002 Farm Act. USDA's rice baseline model is used to compute marketing loan benefits, while direct payments and counter-cyclical payments are estimated from endogenous prices and exogenous policy parameters. Alternative scenarios of reduced marketing loan benefits suggest that projected annual average sector revenue could decline by 4 to 27 percent.

Economic Analysis of Base Acre and Payment Yield Designations Under the 2002 U.S. Farm Act 31
Young, C. Edwin; Skully, David W.; Westcott, Paul C.; Hoffman, Linwood A..
The 2002 Farm Act provided farmland owners the opportunity to update commodity program base acres and payment yields used for calculating selected program benefits. Findings in this report suggest that farmland owners responded to economic incentives in these decisions, selecting those options for designating base acres that resulted in the greatest expected flow of program payments. Decisions of farmland owners in South Dakota, in upland cotton area, and in the Heartland region support the payment-maximization argument. In general, landowners favored maximizing payments over aligning base acres to current or recent plantings. Farmland owners with high-payment base acres, such as rice and cotton, held on to these base acres and, whenever possible, expanded...

ECONOMIC ISSUES IN AGRICULTURAL BIOTECHNOLOGY 31
Shoemaker, Robbin A.; Harwood, Joy L.; Day-Rubenstein, Kelly A.; Dunahay, Terry; Heisey, Paul W.; Hoffman, Linwood A.; Klotz-Ingram, Cassandra; Lin, William W.; Mitchell, Lorraine; McBride, William D.; Fernandez-Cornejo, Jorge.
Agricultural biotechnology has been advancing very rapidly, and while it presents many promises, it also poses as many questions. Many dimensions to agricultural biotechnology need to be considered to adequately inform public policy. Policy is made more difficult by the fact that agricultural biotechnology encompasses many policy issues addressed in very different ways. We have identified several key areas — agricultural research policy, industry structure, production and marketing, consumer issues, and future world food demand — where agricultural biotechnology is dramatically affecting the public policy agenda. This report focuses on the economic aspects of these issues and addresses some current and timely issues as well as longer term issues.

Eliminating Fruit and Vegetable Planting Restrictions: How Would Markets Be Affected? 31
Johnson, D. Demcey; Krissoff, Barry; Young, C. Edwin; Hoffman, Linwood A.; Lucier, Gary; Breneman, Vincent E..
Eighty-nine percent of American households were food secure throughout the entire year in 2005, meaning that they had access, at all times, to enough food for an active, healthy life for all household members. The remaining households were food insecure at least some time during that year. The prevalence of food insecurity declined from 11.9 percent of households in 2004 to 11.0 percent in 2005, while the prevalence of very low food security remained unchanged at 3.9 percent. This report, based on data from the December 2005 food security survey, provides the most recent statistics on the food security of U.S. households, as well as on how much they spent for food and the extent to which food-insecure households participated in Federal and community food...

EVALUATING THE USE OF FUTURES PRICES TO FORECAST THE FARM LEVEL U.S. CORN PRICE 31
Hoffman, Linwood A.; Beachler, Michael.
A model is developed using bases, marketing weights, and a composite of monthly futures and cash prices to forecast a season-average U.S. farm price for corn. Forecast accuracy measures include the mean absolute percentage error and Theil's U-statistic. Futures forecasts are compared with a naïve forecast and WASDE projections. Futures price forecasts are timely and reliable.

FARMERS' VEG RISK PERCEPTIONS AND ADOPTION OF VEG CROP INSURANCE 31
Bard, Sharon K.; Stewart, Robert K.; Hill, Lowell D.; Hoffman, Linwood A.; Dismukes, Robert; Chambers, William.
Producer survey results are analyzed to determine factors influencing value-enhanced grain (VEG) risk perceptions and VEG crop insurance adoption. VEG production is perceived to be riskier than commodity production. VEG types, input costs, and production problems affect risk perceptions. Factors including previous insurance use impact VEG crop insurance adoption.

Measuring the Influence of Commodity Fund Trading on Soybean Price Discovery 31
Plato, Gerald E.; Hoffman, Linwood A..
The increase in commodity fund trading in the agricultural commodity futures markets has raised concern that this trading is degrading the price discovery performance of these markets. We used the Beveridge-Nelson Decomposition procedure to estimate the price discovery performance of the soybean futures and spot markets. We found that the price discovery performance of the soybean futures market has improved along with the increased commodity fund trading. Our results indicated that a portion of the price discovered in the soybean futures market is passed to the spot market.

Price Determination for Corn and Wheat: The Role of Market Factors and Government Programs 31
Westcott, Paul C.; Hoffman, Linwood A..
Annual models for U.S. farm prices for corn and wheat are developed based on market factors as well as government agricultural commodity programs. The pricing relationships utilize a stocks-to-use modeling framework to capture the effects of market supply and demand factors on price determination. This formulation is augmented by factors that represent the changing role of agricultural policies, particularly government price support and stockholding programs. For wheat, international market effects as well as wheat feed use and related crosscommodity pricing considerations also are included. Model properties and model performance measures are presented. Additionally, recent price-forecasting applications of the models are discussed. The relatively simple...

SPATIAL PRICING EFFICIENCY: THE CASE OF U.S. LONG GRAIN RICE 31
Djunaidi, Harjanto; Young, Kenneth B.; Wailes, Eric J.; Hoffman, Linwood A.; Childs, Nathan W..
The spatial rice price relationships for U.S. long grain rough rice are affected by many factors besides the transportation cost between markets, such as milling, processing, cooking and nutritional value as well as physical characteristics. This study applies a time series framework to analyze long run price relationships for Arkansas, Mississippi, Louisiana, Texas and California long grain rice. Johansen's test results showed that at least there are two cointegrating price vectors. However, such a finding is not supported by the ECM model in any of the price series.

TARIFF ESCALATION: IMPACTS ON U.S. AND GLOBAL RICE TRADE 31
Wailes, Eric J.; Durand-Morat, Alvaro; Hoffman, Linwood A.; Childs, Nathan W..
Tariff escalation is an important aspect of protection for domestic milling industries, particularly in Central America. The United States exports over 40 percent of its rice as paddy. This study uses a spatial equilibrium trade model to evaluate the impacts of tariff escalation on U.S. and global long grain paddy and milled rice trade. Tariffs are harmonized for paddy and milled rice at two levels: milled tariff rates and zero. The results indicate that tariff escalation distorts US rice trade in favor of paddy exports, reducing the demand for rice milling and associated value-added activities in the US.

THE 2002 U.S. FARM ACT: IMPLICATIONS OF BASE UPDATING 31
Westcott, Paul C.; Skully, David W.; Young, C. Edwin; Hoffman, Linwood A..
The 2002 Farm Act allowed farm owners to update base acres for direct payments (DPs) and counter-cyclical payments (CCPs) and to update yields for counter-cyclical payments. A minority, about 40 percent, of the 1.9 million enrolled farms choose to update their base acres using 1998-2001 plantings; of these updating farms about three-fourths updated their payment yield for CCPs. Producers with rice and cotton base had a strong economic incentive to maximize base acres for those crops, either by retaining previous base acres if they had shifted to production of alternative crops or by increasing base if they had expanded rice or cotton plantings. Research findings support the hypothesis that base designation reflects payment maximization criteria.

U.S. Peanut Markets Adjust to Policy Reform 31
Dohlman, Erik; Hoffman, Linwood A.; Young, C. Edwin.
With the recent (2002) elimination of the longstanding "marketing quota" system that supported domestic peanut prices at well above world levels, the U.S. peanut sector is in the initial stages of adjusting to a more uncertain, market-oriented environment. At the aggregate level, some early indications are that the adjustment process for U.S. peanut farmers has been difficult, resulting in deep losses of revenue and a rapid exit from peanut production by some producers. In 2003, the value of U.S. peanut production was down 30 percent and prices fell by nearly 25 percent compared with 2001. U.S. peanut planted acreage is at its lowest since 1915, and planted acreage has declined sharply in several important peanut producing States-55 percent in Virginia and...

USING FUTURES PRICES TO FORECAST THE SEASON-AVERAGE U.S. CORN PRICES 31
Hoffman, Linwood A..
A model is developed using basis values (cash prices less futures), marketing weights, and a composite of monthly futures and cash prices to forecast the season-average U.S. corn farm price. Forecast accuracy measures include the absolute percentage error, mean absolute percentage error, squared error, and mean squared error. The futures model forecasts are compared to USDA's WASDE projections. No statistically significance difference was found between the futures model forecasts and the season-average price projections from the U.S. Department of Agriculture. Futures model forecasts are reliable, and timely.
