Traditional time series models assume a constant conditional variance. Realizing the implausibility of this assumption, Bollerslev proposed Generalized Autoregressive Conditional Heteroscedasticity (GARSH) processes, which are characterized by nonconstant conditional variances. In this paper,...

A method for estimating bounded price variation models with rational expectations which incorporates all information implied by rationality is applied to a model of the U.S. corn market. The results indicate that the estimated model performs at least as well as a traditional equilibrium model...

It has long been recognized that usual elasticity and flexibility concepts are of limited value in a multi-equation setting. This is because the response caused by a change in an exogenous variable will have feedback effects as the system obtains a new equilibrium. Consequently, it is necessary...

The existing system for sensing, recording, and reporting climatic conditions has been developed mainly in response to demands of specific clients. Weather conditions provided for airline navigation, agricultural production management, and severe storm tracking, are three examples. Thus, the...

Within the Conservation Reserve (CR) program, a change in program criteria could reduce the amount of erosion material entering our nation's waterways. The inclusion of land adjacent to water bodies, flowing streams, and river waterways may reduce erosion from these lands and improve water...

This study examines the empirical implications of extending the rational expectations hypothesis (REH) to include price uncertainty. Unlike previous studies, a general estimation framework that incorporates both the restrictions on structural parameters and the variance-covariance terms is...

A quarterly econometric model of supply response I the U.S. Hog industry is constructed. This model incorporates relevant biological features of hog production directly into the structural specification. dynamic mean path elasticities of the model are analytically derived with the results...
