Maximum entropy methods of parameter estimation are appealing because they impose no additional structure on the data, other than that explicitly assumed by the analyst. In this paper we prove that the data constrained GME estimator of the general linear model is consistent and asymptotically normal. The approach we take in establishing the asymptotic(More)
We formulate generalized maximum entropy estimators for the general linear model and the censored regression model when there is first order spatial autoregression in the dependent variable and residuals. Monte Carlo experiments are provided to compare the performance of spatial entropy estimators in small and medium sized samples relative to classical(More)
BACKGROUND For most rural households in sub-Saharan Africa, healthy livestock play a key role in averting the burden associated with zoonotic diseases, and in meeting household nutritional and socio-economic needs. However, there is limited understanding of the complex nutritional, socio-economic, and zoonotic pathways that link livestock health to human(More)

Helpful comments and suggestions were provided by two anonymous reviewers. Abstract The objective of this article is to analyze the domestic and international effects of a hypothetical foot-and-mouth disease outbreak in the Mexican cattle industry. A discrete time dynamic optimization model of the Mexican cattle sector is specified, and linked to domestic(More)
Fast food consumption has increased dramatically over the past three decades in U.S., accounting for nearly 35.5% of total away-from-home expenditures in 1999 (USDA/ERS). Given dramatic changes in food consumption, and heightened public concern about health and obesity, there is a considerable need to understand better the factors affecting food consumption(More)
Figure 1. The Ogallala is the largest freshwater aquifer in the world. The maps above show the saturated thickness (vertical distance between the water table and the aquifer floor) of the Ogallala in 1996-97 and the water level changes between 1980 and 1997. The aquifer is depleted in parts of northern Texas and west central Kansas. A large share of(More)
This study evaluates the economic consequences of hypothetical foot-and-mouth disease releases from the future National Bio and Agro Defense Facility in Manhattan, Kansas. Using an economic framework that estimates the impacts to agricultural firms and consumers, quantifies costs to non-agricultural activities in the epidemiologically impacted region, and(More)
