| The Market Risk Game is a computerized simulation game available for IBM PC and Apple II microcomputers that is designed to give realistic practice in making decisions in a risky market environment. It illustrates the use of hedging and put options to reduce risk in livestock and grain markets. It is best suited for individuals who have a basic understanding of commodity trading, but who need experience to solidify their knowledge to a functional level. Through the game this is done without facing the risk of an actual investment or requiring the time involved in watching a market over an extended period. |

| A linear programming algorithm is used to estimate the parameters of a wheat storage decision model. This approach allows objective functions other than minimization of error squared to be used. It is demonstrated that by using a profit maximization objective function, an improved wheat storage decision model can be developed. |

| Elasticities calculated from an econometric model of cost of gain (COG) for cattle in feedlots indicate that COG is considerably less responsive to corn price changes than breakeven budgets assume. This difference in elasticities can lead to substantial errors in COG estimates obtained from budgeting. Size of error will depend upon the initial corn price and the magnitude of corn price change. Given average corn price levels and month-to-month changes, the error in budget-based net revenue projections will be about $3/head. |

| Federal budgetary pressures raise questions regarding the importance of public market information. This study assesses the impact of price discovery and production efficiency of reducing public price and quantity information. The amount and type of information provided to Fed Cattle Market Simulator (FCMS) participants was varied by periodically withholding current and weekly summary information according to a predetermined experimental design. Results show that reducing information increased price variance and decreased marketing efficiency; that is, more cattle were delivered at weights deviating from 1,150 pounds- the least-cost marketing weight in the simulator. These factors, which increase costs, make the industry less competitive. |

| Quality grade, yield grade, and other feedlot performance factors explain much of the variation in profit under grid pricing. Thus, feedlot owners can change profits by adjusting time on feed to influence these performance factors. This research uses growth models, logistic regression, and an optimization process to determine how the optimal number of days on feed changes under different grid pricing structures. It was found that large quality or small yield discounts increases the optimal number of days on feed and small quality or large yield discounts result in fewer days on feed. Losses associated with a grid having large quality discounts are minimized as cattle fed for more days are able to obtain Choice premiums despite the discounts for more Yield... |

| The average real salary of agricultural economists has risen approximately 20 percent over the last two decades. Currently agricultural economists' salaries are approximately 6 percent above the average college of agricultural salary and 1 percent above the average of all university faculty. Over the last two decades agricultural economists' salaries have remained among the highest in the college of agriculture and their numbers have risen as a percentage of total agricultural faculty. Conversely our profession, and the college of agriculture in general, has experienced declines in salary levels and faculty numbers relative to average university salaries and total faculty numbers. |

| A feeder-calf price model is estimated which incorporates elements of break-even budget analysis, including estimates of placement weights, slaughter weights, ration cost, and feed-conversion rates. From this model, a corn price multiplier is calculated which quantifies the corn/feeder-calf price relationship. Because the multiplier includes information on cattle weight, feed conversion, and ration cost, it also provides insight into how feeding programs are altered in response to corn price changes. Changes in feeding programs which occur in response to corn price changes are illustrated with dynamic simulation based on weight, ration cost, and price models presented here. |

| The increased amount of contracting in many agricultural markets continues to be a source of considerable controversy. Some research indicates that increased levels of contracting lead to better prices for processors/users while other research is inconclusive. This article uses an experimental economics approach to study the effects on prices of systematic variations in contracting levels using an experimental model of the fed cattle market. Using experimental economics allowed the control of contracting levels and other variables (e.g. supply levels) that are not possible using industry data. Pricing dynamics changed considerably with increased levels of contracting, but the mean price level was found to be not related to contracting levels. The... |
