A dynamic system of cost-share equations for agricultural inputs is used to test for the presence of input disequilibrium. This dynamic system incorporates a disequilibrium adjustment process into input-share equations derived from a translog cost function. The disequilibrium process is...

This article applies recent developments in time-series modeling to analyze the retail prices of beef, pork, and chicken. Specifically, generalized autoregressive conditional heteroscedasticity (GARCH) models were fitted to these data to determine if, unlike more traditional time-series models,...

Data limitations often limit the time framework in which agricultural commodities are modeled and prices forecasted. Our research provides a technique to alleviate this constraint. By combining an annual econometric model with a quarterly ARIMA model, quarterly forecasts can be made which...

Experimental economics (EE) axioms are directly applied in this paper to contingent valuation method (CVM) field survey procedures. The implications of EE concepts and precepts for conceptualizing and handling potential CVM biases and framing effects also are discussed. It is concluded that EE...

This note further illuminates the strength and direction of starting point bias in iterative bidding procedures. Conflicting recent findings concerning the starting point bias phenomenon are first briefly overviewed. The hypothesis that starting values influence valuations obtained in iterative...

This paper presents a hyperbolic trigonometric (HT) transformation procedure for empirically estimating a cumulative probability distribution function (cdf), from which the probability density function (pdf) can be obtained by differentiation. Maximum likelihood (ML) is the appropriate...

Mean-variance efficient portfolio analysis is applied to situations where not all assets are perfectly price elastic in demand nor are asset moments known with certainty. Estimation and solution of such a model are based on an agricultural banking example. The distinction and advantages of a...

A recent survey indicated that many procedures view risk in a safety-first context. Traditional methods used to impose safety-first constraints in optimization models have often been difficult to implement. This is particularly true when endogenous decisions affect the distribution of the...

While issues in estimating nonmarket values continue to cause concern, resource economists have more reason now than ever before to be optimistic. More progress toward improved measurement has been made in the past six years than in the previous quarter century since development of the...

An elusive restriction maintained in earlier CET supply models with three or more products is shown to result in a potentially serious misspecification. Its impact on empirical estimates is found to be substantial, and an alternative formulation is presented which overcomes the problem while...
