Full Rank Rational Demand Systems AgEcon
LaFrance, Jeffrey T.; Pope, Rulon D..
We extend the set of full rank nominal and deflated income demand systems to rational demand systems of any rank and present a unifying expression for the indirect preferences of all full rank demand models.

Aggregation Theory for Incomplete Systems AgEcon
LaFrance, Jeffrey T.; Beatty, Timothy K.M.; Pope, Rulon D..
Gorman's theory of demand is extended comprehensively to incomplete systems. The incomplete systems approach dramatically increases this class of models. The separate roles of symmetry and adding up are identified in the rank and the functional form of this class of models. We show that symmetry determines rank and the maximum rank is three. We show that adding up and 0o homogeneity determines the functional form and there is no functional form restriction for an incomplete system. We prove that every full rank system and reduced rank systems with a minimal level of degeneracy can be written as a polynomial in a single function of income. A complete set of closed form solutions for the indirect objective functions of this class of models is derived. A...

Agricultural Precautionary Wealth AgEcon
Jensen, Farrell E.; Pope, Rulon D..
Using panel data, the relationship between income uncertainty and the stock of wealth through precautionary saving is examined. Evidence from Kansas data is consistent with the precautionary saving motive in that farm households facing greater uncertainty in income maintain larger stocks of wealth in order to smooth consumption. These results are found by regressing net worth against measures of permanent income (life-cycle income), measures of uncertainty, and demographic variables.

AN EVALUATION OF ECONOMETRIC MODELS OF U.S. FARMLAND PRICES AgEcon
Pope, Rulon D.; Kramer, Randall A.; Green, Richard D.; Gardner, B. Delworth.
Previously published empirical models of U.S. farmland prices are reviewed and reestimated including recent data. It is apparent that structural changes have occurred. A simple single equation econometric model with less economic structure appears to forecast better than a simultaneous equation model. Finally, Box-Jenkins forecasts are roughly as good as those based upon a simultaneous equation econometric model, but somewhat inferior to the single equation model. The results suggest that further research may be needed to explain recent movements of farmland prices.

HOMOGENEITY AND SUPPLY AgEcon
LaFrance, Jeffrey T.; Pope, Rulon D..
Supply functions in the ubiquitous Gorman class are examined for their homogeneity properties. Homogeneity places surprisingly strong restrictions on functional forms. These forms facilitate testing of aggregability given homogeneity or homogeneity given aggregability or testing both.

ON THE COMPETITIVE FIRM UNDER PRODUCTION UNCERTAINTY AgEcon
Pope, Rulon D.; Just, Richard E..
Risky production functions which are commonly in use are shown to be very restrictive. In particular, such functions cannot describe technologies where inputs marginally reduce risk. A simple production function which avoids these restrictions is posited and alternative estimation procedures are discussed. Both maximum likelihood and multistage estimators are discussed.

Building Gorman's Nest AgEcon
LaFrance, Jeffrey T.; Beatty, Timothy K.M.; Pope, Rulon D..
Gorman Engel curves are extended to incomplete systems. The roles of Slutsky symmetry and homogeneity/adding up are isolated in the rank and functional form restrictions for Gorman systems. Symmetry determines the rank condition. The maximum rank is three for incomplete and complete systems. Homogeneity/adding up determines the functional form restrictions in complete systems. There is no restriction on functional form in an incomplete system. Every full rank and minimal deficit reduced rank Gorman system has a representation as a polynomial in a single function of income. This generates a complete taxonomy of indirect preferences for Gorman systems. Using this taxonomy, we develop models of incomplete Gorman systems that nest rank and functional form and...

HEDGING AND PRODUCTION DECISIONS UNDER A LINEAR MEAN-VARIANCE PREFERENCE FUNCTION AgEcon
Chavas, Jean-Paul; Pope, Rulon D..
A firm model of production and hedging decisions is developed using a mean-variance preference function. Comparative static analysis of the model generates a number of testable hypotheses. For example, the influence of price risk, production risk and hedging cost on the optimal level of production and hedging is analyzed in the framework.

Agricultural Arbitrage and Risk Preferences AgEcon
Pope, Rulon D.; LaFrance, Jeffrey T.; Just, Richard E..
A structural inter-temporal model of agricultural asset arbitrage equilibrium is developed and applied to agriculture in the North-Central region of the U.S. The data is consistent with unifying level of risk aversion. The levels of risk aversion are more plausible than previous estimates for agriculture. However, the standard arbitrage equilibrium is rejected; perhaps this is due to the period and the shortness of the period studied.

AN ANALYSIS OF THE ROLE OF FUTURES PRICES, CASH PRICES AND GOVERNMENT PROGRAMS IN ACREAGE RESPONSE AgEcon
Chavas, Jean-Paul; Pope, Rulon D.; Kao, Robert S..
An integrated investigation of futures price, cash price, and government programs is presented in the context of an econometric model of acreage supply response for U.S. corn and soybeans. The analysis refines the role of different sources of price information in the farmers' acreage decision. It is found that the government corn support price program plays a major role in corn and soybean production decisions. Also, the results indicate that futures prices are not good proxies for expected future cash prices in the presence of government programs. This raises questions about the information efficiency of futures prices when government intervenes in the market place.

Agricultural Market Structure, Generic Advertising, and Welfare AgEcon
Cardon, James H.; Pope, Rulon D..
This analysis begins with a definition and discussion of productive advertising. Then, following Dixit and Norman, persuasive advertising is used to study the welfare effects of generic advertising by marketing orders. The study first examines horizontal competition when the competing advertiser is a monopoly, and results show that the socially optimal level of advertising for a competitive marketing order is positive only if advertising raises monopoly output. Next, advertising choices of a marketing order which sells its output to a monopolistic distributor are considered. If the distributor is a monopolist, then marketing order advertising raises welfare. This finding is in marked contrast to the results for the horizontal case studied by Dixit and...

RISK MANAGEMENT STRATEGIES TO REDUCE NET INCOME VARIABILITY FOR FARMERS AgEcon
Falatoonzadeh, Hamid; Conner, J. Richard; Pope, Rulon D..
The most useful and practical strategy available for reducing variability of net farm income is ascertained. Of the many risk management tools presently available, five of the most commonly used are simultaneously incorporated in an empirically tested model. Quadratic programming provides the basis for decision-making in risk management wherein expected utility is assumed to be a function of the mean and variance of net income. Results demonstrate that farmers can reduce production and price risks when a combination strategy including a diversified crop production plan and participation in the futures market and the Federal Crop Insurance Program (FCIP) is implemented.
