Constructing Farm Level Yield Densities from Aggregated Data: Analysis and Comparison of Approaches AgEcon
Cooper, Joseph C.; Langemeier, Michael R.; Schnitkey, Gary D.; Zulauf, Carl R..
Yield variability can be significantly higher at the farm level than at more aggregated levels, including the county. However, due to a dearth of available farm level data, much stochastic analysis involving farm yields utilizes more aggregated yield data as a proxy for the farm level. We empirically evaluate farm-level variability using longitudinal farm level data sets available from the Kansas Farm Management Association and the Illinois Farm Business and Farm Management Association. For corn, soybeans, and wheat, we compare the farm level yield variability obtained from this data to that inferred from Federal crop insurance premiums. The farm management data exhibit lower yield variability than are implied by the crop insurance premiums.

Actuarial Impacts of Loss Cost Ratio Ratemaking in U.S. Crop Insurance Programs AgEcon
Woodard, Joshua D.; Sherrick, Bruce J.; Schnitkey, Gary D..
This study examines the actuarial implications of the loss cost ratio (LCR) ratemaking methodology employed by the Risk Management Agency as a component of base rates for U.S. crop insurance programs, and identifies specific conditions required for the LCR methodology to result in unbiased rates when liabilities trend. Specifically, constant relative yield risk resulting in growing absolute variance through time and other restrictive requirements are required for the LCR to result in unbiased rates. These requirements are tested against a large farm-level data set for Illinois corn. Our findings indicate that the conditions required for appropriate use of the LCR methodology are violated for this high premium volume market, resulting in large implied rate...

EVALUATION OF RISK REDUCTIONS ASSOCIATED WITH MULTI-PERIOL CROP INSURANCE PRODUCTS AgEcon
Schnitkey, Gary D.; Sherrick, Bruce J.; Irwin, Scott H..
This research examines risk-return tradeoffs across a full range of crop insurance products and coverage levels. Results indicate that farm-level products reduce risk for low probability events, but that risk reductions often are not large for events that occur with more regularity. Risk reductions vary with yield variability; with counties that have higher yield variability also experiencing greater risk reductions through the use of crop insurance.

MARKETING INFORMATION AS A CONSTRAINT TO LOCALLY GROWN PRODUCE: EVIDENCE FROM OHIO AgEcon
Jones, Eugene; Batte, Marvin T.; Schnitkey, Gary D..
A random sample of 200 Ohio fruit producers were surveyed in January 1988, regarding their use of information for decision making. Survey responses were used to determine if improved marketing information increases the likelihood of Ohio fruit producers gaining a larger share of Ohio's produce market. Results from the production adequacy equations show that larger producers and those marketing a predominate share of their fruit through wholesalers and retailers are the ones most likely to agree that their fruit production is limited by insufficient marketing information. These results suggest an opportunity for Ohio to gain a larger share of the produce market.

A SOCIOECONOMIC ANALYSIS OF MARKETING INFORMATION USAGE AMONG OHIO FRUIT PRODUCERS AgEcon
Jones, Eugene; Batte, Marvin T.; Schnitkey, Gary D..
Farm producers attempt to mitigate risk and uncertainty by utilizing accurate and reliable information. This research attempts to identify sources of information used by Ohio fruit producers and then determine which of these sources are best meeting their information needs. Results are based on a logit analysis of Ohio fruit producers and several factors are shown to influence producers' evaluation of the "adequacy" of their marketing information. Among these factors are age, business size, education, type of enterprise, and types of information sources. Reported findings have implications for marketing efficiency, particularly if producers' evaluation of information as adequate is positively related to its efficient use.

Testing for Yield Persistency: Is It Skill or is It Luck? AgEcon
Urcola, Hernan A.; Schnitkey, Gary D.; Irwin, Scott H.; Sherrick, Bruce J..
This study uses corn yield data from McLean County, Illinois to test whether farmer skill influences yields. This analysis is conducted by performing persistency tests on unadjusted, soil productivity adjusted (PA), and productivity and input intensity adjusted (PIA) yields. Correlation analysis and winner/loser tables indicate that unadjusted, PA, and PIA yields exhibit persistency across time. PIA yields exhibiting persistency is consistent with farmer skill influencing yield. Hence, our results support the hypothesis that farmer skill influences yields.

ESTIMATING FARM-LEVEL YIELD DISTRIBUTIONS FOR CORN AND SOYBEANS IN ILLINOIS AgEcon
Zanini, Fabio C.; Irwin, Scott H.; Schnitkey, Gary D.; Sherrick, Bruce J..
Many yield modeling approaches have been developed in attempts to provide accurate characterizations of farm-level yield distributions due to the importance of yield uncertainty in crop insurance design and rating, and for managing farm-level risk. Competing existing models of crop yields accommodate varying skewness, kurtosis, and other departures from normality including features such as multiple modes. Recently, the received view of crop yield modeling has been challenged by Just and Weninger who indicate that there is insufficient evidence to reject normality given data limitations and potential methodological shortcomings in controlling for deterministic components (trend) in yields. They point out that past empirical efforts to estimate and...

A MICROCOMPUTER ANALYSIS OF FARM FINANCIAL PERFORMANCE AgEcon
Schnitkey, Gary D.; Barry, Peter J.; Ellinger, Paul N..
This article describes the properties of the Farm Financial Simulation Model (FFSM). FFSM is a tool for analyzing the financial consequences of various managerial strategies and policy options that may be implemented in responding to farm financial stress. Various farm types from different geographical regions having differing enterprises, financial structures, tenure arrangements, and consumption patterns can be analyzed. The emphasis of FFSM is placed on modeling a farm's profitability, liquidity, solvency, and financial position and the model produces a coordinated set of financial statements and an extensive set of financial ratios over a four-year period.

Price and Profit: Investigating a Conundrum AgEcon
Zulauf, Carl R.; Schnitkey, Gary D.; Norden, Carl T..
Although few in number, studies consistently find that price explains little, if any, of the variation in profit across farms. This contrasts with farmers' opinions regarding the importance of price, as well as the use of price supports as a primary policy instrument. Using farm level data from the Illinois Farm Business Farm Management program for calendar years 1996 through 2004, a potential explanation for this conundrum is identified. Price is significantly more correlated with a farmer's variation in management return from year to year (approximately, +0.45) than with the variation in management return across farmers (approximately, +0.10). Thus, the conundrum arises out of different perspectives: farmers focus on the performance of their own farm...

UPDATING CORN PROGRAM PAYMENT YIELDS: ARE FARM OPERATORS DIFFERENTIALLY AFFECTED? AgEcon
Thayer, Sharon; Zulauf, Carl R.; Schnitkey, Gary D.; Forster, D. Lynn.
Crop yields which determine farm income deficiency payments have been frozen at 1981-1985 levels since 1986. Data from a longitudinal survey of Ohio farm operators are analyzed to evaluate whether updating payment yields will differentially affect farm operators. Results of the analysis imply that farm operators who operate larger farms, live in counties with higher yields, and have higher fertilizer and pesticide expenses per acre of corn will benefit more. In addition, low (high) existing payment yields are understated (overstated) relative to updated payment yields.

Measurement of Farm Credit Risk: SUR Model and Simulation Approach AgEcon
Yan, Yan; Barry, Peter J.; Paulson, Nicholas D.; Schnitkey, Gary D..
The study addresses problems in measuring credit risk under the structure model, and then proposes a seemingly unrelated regression model (SUR) to predict farms’ ability in meeting their current and anticipated obligations in the next 12 months. The empirical model accounts for both the dependence structure and the dynamic feature of the structure model, and is used for estimating asset correlation using FBFM data for 1995-2004. Farm credit risk is then predicted by copula based simulation process with historical default rates as benchmark. Results are reported and compared to previous studies on farm default.

CROP INSURANCE VALUATION UNDER ALTERNATIVE YIELD DISTRIBUTIONS AgEcon
Zanini, Fabio C.; Sherrick, Bruce J.; Schnitkey, Gary D.; Irwin, Scott H..
Considerable disagreement exists about the most appropriate characterization of farm-level yield distributions. Yet, the economic importance of alternate yield distribution specifications on insurance valuation, product designs and farm-level risk management has not been investigated or documented. The results of this study demonstrate that large differences in expected payments from popular crop insurance products can arise solely from the parameterization chosen to represent yields. The results suggest that the frequently unexamined yield distribution specification may lead to incorrect conclusions in important areas of insurance and risk management research such as policy rating, and assessment of expected payments from policies.

THE IMPACT OF POLLUTION CONTROLS ON LIVESTOCK-CROP PRODUCERS AgEcon
Schnitkey, Gary D.; Miranda, Mario J..
A discrete-time, continuous-space model of a livestock- crop producer is used to examine the long-run effects of phosphorus runoff controls on optimal livestock production and manure application practices. Quantity restrictions and taxes on phosphorus application are shown to reduce livestock supply and impose greater costs on livestock-crop producers than on crop-only producers. Restrictions on manure application, without accompanying restrictions on commercial fertilizer application, will have only a limited effect on phosphorus runoff levels.

Average Crop Revenue Election, Crop Insurance, and Supplemental Revenue Assistance: Interactions and Overlap for Illinois and Kansas Farm Program Crops AgEcon
Zulauf, Carl R.; Schnitkey, Gary D.; Langemeier, Michael R..
Farm-level data from Illinois and Kansas for the 1991–2007 crops are used to examine the interaction and overlap among crop revenue insurance, Supplemental Revenue Assistance (SURE), and Average Crop Revenue Election (ACRE). Compared with 75% Crop Revenue Coverage Insurance (75% CRCP), ACRE provides more payments and has a greater impact on minimum farm revenue for the Illinois farms. In contrast, for the Kansas farms, 75% CRCP has the greater impact. SURE’s relative impact on the Illinois and Kansas farms depends on the metric. The overlap in payments from ACRE and 75% CRCP resulting from covering the same part of the revenue risk distribution is estimated to be less than 5% of ACRE payments. Several proposals for improving the farm safety net are...

EXISTENCE OF UNIQUE LIMITING PROBABILITY VECTORS IN STOCHASTIC PROCESSES WITH MULTIPLE TRANSITION MATRICES AgEcon
Mjelde, James W.; Harris, Wesley D.; Conner, J. Richard; Schnitkey, Gary D.; Glover, Michael K.; Garoian, Lee.
Concepts associated with stochastic process containing multiple transition matricies are discussed. It is proved that under certain conditions, a process with m transition matrices has m unique limiting probability vectors. This result extends the notion of discrete Markov processes to problems with intrayear and interyear dynamics. An example using a large DP model illustrates the usefulness of the concepts developed to applied problems.

THE EFFECTS OF INCLUDING BANKRUPTCY ON DYNAMIC INVESTMENT DECISIONS AgEcon
Novak, Frank S.; Schnitkey, Gary D..
This article evaluates the effects of including the costs of bankruptcy in a dynamic model of off-farm investment decisions using a stochastic dynamic programming (SDP) model which incorporates the stochastic dynamic nature of investment returns and the interrelationships between financial structure and investment decisions. Our results suggest that in the presence of bankruptcy, optimal investment decisions are affected by financial structure and financial market conditions. Ignoring bankruptcy costs in determining investment decisions results in a high probability of bankruptcy.

The Role of Farmland in an Investment Portfolio: Analysis of Illinois Endowment Farms AgEcon
Noland, Kevin; Norvell, Jonathan; Paulson, Nicholas D.; Schnitkey, Gary D..
The recent financial crisis has renewed interest in alternative asset classes such as farmland. Previous work has shown that farmland may provide expected return premiums while adding little additional risk to a diversified portfolio. However, these studies have been based on relatively short time periods and aggregated data on farmland returns. This analysis contributes to this literature using farm-level data from the University of Illinois endowment farms, providing additional evidence that farmland could play a favorable role within an investment portfolio. The implications of these results extend to the use of farmland within general investment portfolios.

New Generation Grain Marketing Contracts AgEcon
Hagedorn, Lewis A.; Irwin, Scott H.; Martines-Filho, Joao Gomes; Good, Darrel L.; Sherrick, Bruce J.; Schnitkey, Gary D..
The purpose of this research report is to summarize the features of several types of "new generation" grain marketing contracts. Over the last several years, new types of grain marketing contracts have been developed by the grain industry in an attempt to improve the results of the marketing process for farmers. These products use automated pricing rules, discretionary marketing on the part of a professional advisor, options strategies, or some combination of all three; their goal is to achieve a price for the farmer near or above the "average" price offered by the market over a given time. Reports in the farm media suggest interest in new generation contracts has increased rapidly in recent years. This publication describes some of the contracts...

Revenue Risk Reduction Impacts of Crop Insurance in a Multi-Crop Framework AgEcon
Woodard, Joshua D.; Sherrick, Bruce J.; Schnitkey, Gary D..
This study develops a multi-crop insurance model which is employed to evaluate crop insurance decisions when several crops are produced jointly. The results suggest that the diversification effects derived from producing multiple crops can substantially alter the risk reduction impacts of crop insurance versus if the decision is viewed from the perspective of a single crop. Further, the relatedness of crop production and price responses among crops differs considerably across insurance products and strategies. As a result, insurance strategies that might provide the maximum risk reduction for an individual crop do not necessarily carry over to the multi-crop case.
