A GENERAL FRAMEWORK FOR GRAIN BLENDING AND SEGREGATION AgEcon
Sivaraman, Eswar; Lyford, Conrad P.; Brorsen, B. Wade.
The Hennessy and Wahl model of optimal grain blending and segregation (GBS) is extended to the case where it is not possible to separate components within a load. Analytical solutions are not available when segregation is the optimal strategy, and so solutions are obtained with nonlinear optimization. The model is then used to determine the optimal sorting of hard red winter wheat by protein content. Most of the benefits from sorting can be obtained with only two bins.

A Retail Sales / Sales Tax Paradox AgEcon
Lansford, Notie H., Jr.; Brorsen, B. Wade; Woods, Michael D..
Small communities experiencing slow to negative growth sometimes increase their local sales tax rate in order to maintain or expand public services. A cross-sectional, time series model is used to investigate possible unintended consequences. Negative elasticities are found for tax rates above the norm, resulting in reduced retail trade.

ACTUAL FARMER MARKET TIMING AgEcon
Brorsen, B. Wade; Anderson, Kim B..
One maxim that has been circulating among farmers is that most farmers sell in the lower third of the market. This maxim is soundly rejected using data from Oklahoma elevators. In fact, roughly half of producers sell in the upper third of the market. Thus, there does not seem to be a great need for producers to hire a market advisor to do their marketing for them. But, some farmers do store longer than is optimal and they could be encouraged to sell sooner after harvest. In the short run, farmers sold after price increases and held after price decreases. Price movements in the days after a large number of sales were no different than price movements after few sales. While farmers are noise traders in the short run, it does appear that they are responding...

ADOPTION OF DOUBLE-CROPPING SOYBEANS AND WHEAT AgEcon
Shapiro, Barry Ira; Brorsen, B. Wade; Doster, D. Howard.
Double-cropping of soybeans and wheat is often promoted by extension personnel. This paper seeks to explain how the decision to adopt double-cropping is made, using a Tobit regression model. Tobit makes use of more of the information in the data set than do logit or probit and explains not only the decision to double-crop but also the rate of adoption. The paper considers factors such as profit and risk perceptions and risk which have not been included in the past models used to explain adoption of technology. The results show that risk perception is important. Contrary to the findings of some other adoption studies, this decision is not influenced by human capital factors. The farmers who double-crop are more highly leveraged and appear to do so...

AGRICULTURAL ECONOMICS RESEARCH AND EXTENSION MARKETING PROGRAMS: HOW WELL ARE THEY INTEGRATED? AgEcon
Brorsen, B. Wade; Anderson, Kim B..
Extension marketing economists were surveyed to determine whether they are using available research results and whether research is being conducted on topics relevant to extension marketing economists. In some cases, the beliefs of extension marketing economists differ from recent research results. The research topics recommended by extension economists and the topics of papers presented at the 1994-97 annual NCR-134 Conference on Applied Commodity Price Analysis, Forecasting, and Market Risk Management are well matched. While relevant research is being done, many extension economists desire marketing strategies that both reduce risk and increase income. Research, however, has not produced such strategies.

AIDS VERSUS ROTTERDAM: A COX NONNESTED TEST WITH PARAMETRIC BOOTSTRAP AgEcon
Dameus, Alix; Brorsen, B. Wade; Sukhdial, Kullapapruk Piewthongngam; Richter, Francisca G.-C..
A Cox nonnested test with parametric bootstrap is developed to select between the linearized version of the First Difference Almost Ideal Demand System (FDAIDS) and the Rotterdam model. The Cox test with parametric bootstrap is expected to be more powerful than the various orthodox tests used in past research. The new approach is then used for U. S. meat demand (beef, pork, and chicken) and compared to results obtained with an orthodox test. The orthodox test gives inconsistent results. In contrast, under the same varied conditions, the Cox test with parametric bootstrap consistently indicates that the Rotterdam model is preferred to the FDAIDS.

AIDS VERSUS THE ROTTERDAM DEMAND SYSTEM: A COX TEST WITH PARAMETRIC BOOTSTRAP AgEcon
Dameus, Alix; Richter, Francisca G.-C.; Brorsen, B. Wade; Sukhdial, Kullapapruk Piewthongngam.
A Cox test with parametric bootstrap is developed to select between the linearized version of the First-Difference Almost Ideal Demand System (FDAIDS) and the Rotterdam model. A Cox test with parametric bootstrap has been shown to be more powerful than encompassing tests like those used in past research. The bootstrap approach is used with U.S. meat demand (beef, pork, chicken, fish) and compared to results obtained with an encompassing test. The Cox test with parametric bootstrap consistently indicates the Rotterdam model is preferred to the FDAIDS, while the encompassing test sometimes fails to reject FDAIDS.

Can Multiyear Rollover Hedging Increase Mean Returns? AgEcon
Yoon, Byung-Sam; Brorsen, B. Wade.
Both market advisors and researchers have often suggested multiyear rollover hedging as a way to increase producer returns. This study determines whether rollover hedging can increase expected returns for producers. For rollover hedging to increase expected returns, futures prices must follow a mean-reverting process. To test for the existence of mean reversion in agricultural commodity prices, this study uses a longer set of price data and a wider range of test procedures than past research. With the use of both the return predictability test from long-horizon regression and the variance ratio test, we find that mean reversion does not exist in futures prices for corn, wheat, soybean, soybean oil, and soybean meal. The findings are consistent with...

Can Real Option Value Explain Why Producers Appear to Store Too Long? AgEcon
Kim, Hyun Seok; Brorsen, B. Wade.
Previous studies suggest that producers tend to store crops longer than makes economic sense. Since decisions to sell are irreversible, there can be a real option value from waiting to sell grain. This real option value may explain why producers appear to store too long. A seasonal mean reversion model is estimated that allows prices to be a random walk within a season, but mean reverting across crop years. Unless prices are extremely low, it is optimal for producers to sell before the mean reversion begins. Thus, the real option value of waiting cannot explain why producers seem to store at a loss in the latter part of crop years.

CAN STRUCTURAL CHANGE EXPLAIN CHANGES IN RETURNS TO TECHNICAL ANALYSIS? AgEcon
Kidd, Willis V.; Brorsen, B. Wade.
Returns to managed futures funds and Commodity Trading Advisors (CTAs) have decreased dramatically during the last several years. Since these funds overwhelmingly use technical analysis, this research examines futures prices to determine if there is evidence of a structural change in futures price movements that could explain the reduction in fund returns. Bootstrap tests are used to test significance of a change in statistics related to daily returns, close-to-open changes, breakaway gaps, and serial correlation. Results indicate that several statistics have changed across a broad range of commodities indicating futures price fluctuations have changed. The lower price volatility, decreased price reaction time, and decreased serial correlation may partly...

Can the Federal Reserve Bank’s Survey of Agricultural Credit Conditions Forecast Land Values? AgEcon
Zakrzewicz, Christopher J.; Brorsen, B. Wade; Briggeman, Brian C..
The value of land dominates the financial structure of most American agricultural production firms, and land values are an important factor in long-term agricultural planning and risk management. As the primary source of collateral for farm loans, farmland values have significant implications for both producers as well as bankers financing agricultural loans. The Federal Reserve Bank of Kansas City’s Survey of Agricultural Credit Conditions is an expert opinion survey in which agricultural bankers provide land value forecasts. As the survey has drawn increased attention, the survey has drawn criticism regarding its use qualitative data to forecast land values. Our research examines the value of the survey data with respect to its ability to forecast...

CARIBBEAN DEMAND OF U.S. AND REST-OF-THE-WORLD STARCHY FOOD (WHEAT, RICE, CORN, AND FRESH POTATOES): A RESTRICTED SOURCE DIFFERENTIATED ALMOST IDEAL DEMAND SYSTEM AgEcon
Dameus, Alix; Tilley, Daniel S.; Brorsen, B. Wade.
This study provides elasticity estimates of the Caribbean demand for U. S. and Rest-of-the-World starchy foods (unmilled wheat and flour, rice, corn and fresh potatoes) using the Restricted Source Differentiated Almost Ideal Demand System (RSDAIDS) model. Caribbean per capita import demand curves for U.S. and Rest-of-the-World (ROW) are own-price unitary elastic for U. S. wheat, and own-price inelastic for U.S. rice and ROW wheat and rice. The implication is that reductions by any means in U. S. or ROW export prices of wheat and rice will increase U.S. or ROW exported quantities in the Caribbean, while at the same time securing food security through import quantity in the Caribbean. Wheat is not produced in the Caribbean. U. S. wheat price policy oriented...

CASH MARKETING STYLES AND PERFORMANCE PERSISTENCE OF WHEAT PRODUCERS AgEcon
Cunningham, Lewis T., III; Brorsen, B. Wade; Anderson, Kim B..
Years of research have been dedicated to determining the best time for producers to sell their commodities. Researchers have developed basis models, market efficiency tests, hedging/risk models, price forecasting models, and many other models in an attempt to help producers. There is a vast amount of material on how economists believe that a rational producer should act and react in the market place. However, there is little research on how producers actually sell commodities. This paper first measures the extent to which producers display an active or mechanical marketing style using individual farmer sales. Next, tests of performance persistence are conducted to determine if there is any advantage to an active marketing style. The results show that...

Cash Wheat Marketing: Strategies for Real People AgEcon
Brorsen, B. Wade; Anderson, Kim B..
A new paradigm is needed in extension marketing programs. Attempts to help producers time the market, either through cask sales or futures trading, appear to be of little benefit. Marketing extension programs need to place less emphasis on outlook and futures trading and more emphasis on simple marketing strategies that people really use. An empirical example of strategies for Oklahoma wheat producers shows selling cash wheat at harvest and participating in government programs as the preferred marketing strategy. Implications for extension programs in other states are that extension programs can help producers decide whether to store their grain and whether to participate in farm programs.

Comparison of Alternative Sources of Farmland Values AgEcon
Zakrzewicz, Christopher J.; Brorsen, B. Wade; Briggeman, Brian C..
Consistent and reliable data on farmland values is critical to assessing the overall financial health of agricultural producers. However, little is known about the idiosyncrasies and similarities of standard land value data sources – U.S. Department of Agriculture, Federal Reserve Bank land value surveys, and transaction prices. All three data sources are highly correlated, but transaction prices tend to be higher, especially for irrigated cropland and ranchland. USDA land values are reported as representing land values on January first, but instead they more closely represent first and second quarter land values according to a multi-state comparison to changes in quarterly Federal Reserve land values. Given the finding that first quarter Federal Reserve...

CONSOLIDATING RURAL SCHOOL DISTRICTS: POTENTIAL SAVINGS AND EFFECTS ON STUDENT ACHIEVEMENT AgEcon
Jacques, Charles; Brorsen, B. Wade; Richter, Francisca G.-C..
One frequently proposed policy is to consolidate rural school districts in order to save money by obtaining economies of size. The effects of school district size on both expenditures and standardized test scores are estimated for Oklahoma. Results indicate that economies of scale with respect to expenditures per student exist up to an average daily membership (ADM) of 965 students, but that as school districts become larger, tests scores decline. Even if savings in school district administration from consolidation are spent on instruction, state average tests scores would decrease slightly. Thus, school district consolidation can reduce costs, but it will also reduce student learning.
