A Hedonic Price Analysis of Corn and Soybean Herbicides AgEcon
Vassalos, Michael; Dillon, Carl R..
Herbicides account for approximately 2.2% of total farm expenses and are applied to more than 80% of farmland in the USA. The widespread adoption of herbicides contributed to the increased and relatively cheaper productivity of modern intensively managed agricultural systems in developed countries. The present study uses a hedonic framework to analyze the effect of selected attributes on the price of corn and soybean herbicides. Two different empirical models were estimated separately for the two crops. The data include information on 51 herbicides, 27 for corn and 24 for soybean crops used in Kentucky. Findings indicate that efficacy against weeds and crop response (illustrates the potential of an herbicide to injure a crop) of herbicides are significant...

A Whole Farm Analysis of the Influence of Auto-Steer Navigation on Net Returns, Risk, and Production Practices AgEcon
Shockley, Jordan M.; Dillon, Carl R.; Stombaugh, Timothy S..
A whole farm economic analysis was conducted to provide a detailed assessment into the economic, risk, and production implications due to the adoption of auto-steer navigation. It was determined that auto-steer navigation was profitable for a grain farmer in Kentucky with net returns increasing up to 0.90% ($3.35/acre). Additionally, the technology could be used in reducing production risk. Adoption of the technology also alters production practices for optimal use.

BIOPHYSICAL SIMULATION IN SUPPORT OF CROP PRODUCTION DECISIONS: A CASE STUDY IN THE BLACKLANDS REGION OF TEXAS AgEcon
Dillon, Carl R.; Mjelde, James W.; McCarl, Bruce A..
Economic feasibility of Texas Blacklands corn production in relation to sorghum, wheat, and cotton is studied. Biophysical simulation generated yield data are integrated with an economic decision model using quadratic programming. Given the various scenarios analyzed, corn is economically feasible for the Blacklands. A crop mix of half corn and half cotton production is selected under risk neutrality with wheat entering if risk aversion is present. Corn and grain sorghum production are highly substitutable. Profit effects attributed to changing corn planting dates are more pronounced than profit changes resulting from altering corn population or maturity class.

Choice of Optimal Planting and Marketing Decisions for Fresh Vegetable Producers: A Mathematical Programming Approach AgEcon
Vassalos, Michael; Dillon, Carl R.; Coolong, Tim.
This study combines whole farm economic analysis with biophysical simulation techniques in order to achieve a twofold objective. First, the study seeks to develop a multiple enterprise vegetable farm model with a production and marketing decision interface and, second, to determine optimal production practices for Kentucky vegetable growers. Three vegetable crops are examined: tomatoes, bell peppers and sweet corn. The findings indicate that the risk associated with vegetable production can be significantly mitigated with diversification of production mix and with a greater number of transplanting dates. However, this reduction in risk comes at a high cost in terms of expected net returns.

FARM DECISION-MAKING IN A MULTIFUNCTIONAL CONTEXT: THE CASE OF CONVENTIONAL AND ORGANIC FARMING IN KERKINI DISTRICT, GREECE AgEcon
Vassalos, Michael; Dillon, Carl R.; Karanikolas, Pavlos.
Multifuncionality has become a central concern at both conceptual and empirical levels. In this study, a comparative evaluation of the economic performance of conventional and multifunctional farms (mainly organic farms) was conducted for Lake Kerkini region (North Greece) with the use of mixed integer non-linear programming method. Economic performance was evaluated in terms of farm income, resource allocation, production level etc. The results indicate that multifunctional farms have overall better economic performance and young farm managers are keener to adopt multifunctional farming than the older ones.

GO AHEAD, COUNT YOUR CHICKENS: CROSS-HEDGING STRATEGIES IN THE BROILER INDUSTRY AgEcon
Maynard, Leigh J.; Dillon, Carl R.; Carter, Joy.
Some suppliers of broilers without giblets (WOG) offer customers a choice between paying Urner Barry's WOG quote or a formula price based on futures prices. From a buyer's perspective, the formula price examined in this study is second-degree stochastic dominant. The formula price allows the seller to set perfect cross-hedges of WOGs with corn and soymeal. Stochastic dominance and mean variance results suggested that the seller's dominant strategy would shift from the Urner Barry quote to the hedged formula price as risk aversion increased. Input-based formula pricing may be usefully extended to other industries.

Impacts of Observation Deleting Standards on Profitability Analysis of Precision Agriculture AgEcon
Song, Baohui; Dillon, Carl R.; Mueller, Thomas.
This research explores a possible reason for the inconsistent results from previous study on the profitability analysis in precision agriculture - different standards of identifying possible erroneous observations for PA datasets. By comparing the results from the different standards of identifying possible erroneous observations, this research raises concerns about the negative impacts of different standards of identifying possible erroneous observations on the profitability analysis of PA, and provides some suggestions for the standard which could be used in the future profitability analysis of PA.

MICROECONOMIC EFFECTS OF REDUCED YIELD VARIABILITY CULTIVARS OF SOYBEANS AND WHEAT AgEcon
Dillon, Carl R..
Economic analysis was conducted on hypothetical agronomic research on new crop cultivars for Arkansas dryland soybean and wheat producers. In relation to farmers’ attitudes toward risk, the microeconomic effects and level of adoption of yield variability reducing cultivars were analyzed utilizing a production management decision-making model formulated with mathematical programming techniques. The study indicated that negative covariance between crops continues to be an effective means of reducing production risk associated with yield variability. However, under varying circumstances, agronomic research on the breeding of new soybean and wheat cultivars with reduced yield variability is worthwhile if there is only slight concurrent reduction in expected...

PERFECT CROSS-HEDGING OPPORTUNITIES VIA FORMULA PRICING: THE CASE OF THE BROILER INDUSTRY AgEcon
Carter, Joy; Maynard, Leigh J.; Dillon, Carl R..
One supplier of broilers without giblets (WOGs) offers customers a choice between paying Urner Barry's WOG quote or a formula price based on futures prices. From a buyer's perspective, the formula price is second-degree stochastic dominant, thus acting a marketing inducement. The formula price allows the seller to set almost perfect cross-hedges of WOGs with corn and soymeal. Stochastic dominance results suggested that the seller's dominant strategy would shift from the unhedged Urner Barry quote to the unhedged formula price as risk aversion increased. The hedged formula price was prominent in optimal portfolios of pricing strategies.
