Multivariate AIM Consumer Demand Model Applied to Dried Fruit, Raisins, and Dried Plums AgEcon
Brant, Molly; Marsh, Thomas L.; Featherstone, Allen M.; Crespi, John M..
Abstract: We estimate a semi-nonparametric demand system based on a multivariate version of the Muntz-Szatz series expansion which is called the Asymptotically Ideal Model (AIM). The model is applied to consumer demand for dried fruits, raisins, and dried plums. Results from the first and second order AIM expansions suggest that the second order expansion leads to a more economically consistent model, but the likelihood ratio test indicates the AIM(2) model was not a statistical improvement over the AIM(1) model.

Foreign-Market Entry Strategies in the European Union AgEcon
Stiegert, Kyle W.; Ardalan, Archie Amir; Marsh, Thomas L..
This study utilized intra-firm, socio-cultural, geographical-proximity, and political-stability variables to explain bimodal foreign direct investment (FDI) patterns by agri-food and beverage multinational companies into and within the European Union. A logit framework incorporated a unique-count database of firm-level investment patterns from 1987–1998. The results showed the 1992 structural changes under the Maastricht Treaty increased the probability of wholly owned FDI modes such as greenfields and buyouts. The model also found that past modal strategies of firms, language barriers, and exchange-rate volatility all correctly explained modal investment patterns. The results provide important contributions toward understanding modal investment strategies...

Economic substitution for US wheat food use by class AgEcon
Marsh, Thomas L..
Wheat for food use is conceptualised as an input into flour production and demand is derived from an industry profit function to quantify price responsiveness and economic substitutability across wheat classes. Price and substitution elasticities are estimated for hard red winter, hard red spring, soft red wheat, soft white winter and durum wheat. In general, hard red winter and spring wheat varieties are much more responsive to their own price than are soft wheat varieties and durum wheat. Substitution elasticities indicate that hard red winter and hard red spring wheat are economic substitutes for milling purposes.

Invasive Species Management: Foot-and-Mouth Disease in the U.S. Beef Industry AgEcon
Zhao, Zishun; Wahl, Thomas I.; Marsh, Thomas L..
A conceptual bio-economic framework that integrates dynamic epidemiologicaleconomic processes was designed to analyze the effects of invasive species introduction on decision-making in a livestock sector (e.g., production and feeding). The framework integrates an epidemiological model, a dynamic livestock production model, domestic consumption, and international trade. The integrated approach captures producer and consumer responses to, and welfare outcomes of, livestock disease outbreaks, as well as alternative invasive species management policies. Scenarios of foot-and-mouth disease are simulated to demonstrate the usefulness of the framework in facilitating invasive species policy design.

DERIVED DEMAND FOR WHEAT BY CLASS AgEcon
Terry, Justin J.; Marsh, Thomas L..
To quantify price responsiveness and economic substitutability among wheat classes, derived demand functions were specified from a normalized quadratic profit function. Own-price and cross-price elasticities were estimated for hard red winter, hard red spring, soft wheat (combined red and white), and durum wheat. In general, soft wheat varieties were less responsive to their own price than were hard wheat varieties. Cross-price elasticities indicate that hard red winter wheat, hard red spring wheat, and soft wheat varieties are economic substitutes. Cross-price elasticities are different from those previously reported, which can have important policy implications.

Comparing Heterogeneous Consumption in US and Japanese Meat and Fish Demand AgEcon
Tonsor, Glynn T.; Marsh, Thomas L..
This article uses national, quarterly data to conduct an empirical analysis of pre-committed meat and fish demand by US and Japanese households using the Generalized Almost Ideal Demand System (GAIDS). US consumers are found to hold pre-committed demand for beef and pork, while Japanese consumers appear to possess significant pre-committed demand for beef and fish. This provides evidence to partly explain observed differences in Japanese and US consumer reactions to non-price and non-income effects in beef, pork, poultry, and fish. In addition, the first known empirical comparison of how the GAIDS and more traditional AIDS models assess meat and fish demand is offered with both in- and out-of-sample evaluations.

Welfare Implications of Washington Wheat Breeding Programs AgEcon
Nogueira, Lia; Marsh, Thomas L..
We calculate the welfare effects of the WSU wheat breeding programs for producers and consumers in Washington State, Oregon, Idaho, the United States and the rest of the world. We develop a partial equilibrium multi-region, multi-product, multi-variety trade model for wheat that provides consumer, producer and total surplus for each wheat class and region. Our results provide evidence suggesting that WSU wheat breeding programs have increased welfare in Washington State, in the United States and the rest of the world.

INFORMATION THEORETIC ALTERNATIVES TO TRADITIONAL SIMULTANEOUS EQUATIONS ESTIMATORS IN THE PRESENCE OF HETEROSKEDASTICITY AgEcon
Marsh, Thomas L.; Mittelhammer, Ronald C..
Finite sampling properties of information theoretic estimators of the simultaneous equations model, including maximum empirical likelihood, maximum empirical exponential likelihood, and maximum log Euclidean likelihood, are examined in the presence of selected forms of heteroskedasticity. Extensive Monte Carlo experiments are used to compare finite sample performance of Wald, Likelihood ratio, and Lagrangian multiplier tests constructed from information theoretic estimators to those from traditional generalized method of moments.

TRUNCATED REGRESSION IN EMPIRICAL ESTIMATION AgEcon
Marsh, Thomas L.; Mittelhammer, Ronald C..
In this paper we illustrate the use of alternative truncated regression estimators for the general linear model. These include variations of maximum likelihood, Bayesian, and maximum entropy estimators in which the error distributions are doubly truncated. To evaluate the performance of the estimators (e.g., efficiency) for a range of sample sizes, Monte Carlo sampling experiments are performed. We then apply each estimator to a factor demand equation for wheat-by-class.

THE IMPACTS OF DEMOGRAPHICS AND HEALTH INFORMATION ON MEAT DEMAND AgEcon
Wilson, Christine A.; Marsh, Thomas L..
Little research has quantified the impact of demographics and health information on meat demand, and no previous study has examined multiple demographic and health information variables simultaneously in a demand system, which this research does. Results of this study suggest that changes in demographic characteristics and increasing health awareness have influenced the changes in meat demand.

SPATIAL HEDONIC ANALYSIS OF VETERINARIAN INCOME AgEcon
Fanning, Jasper; Marsh, Thomas L..
We investigate a hedonic model for veterinarian income using survey data from the American Veterinarian Medical Association. Diagnostic testing indicates the presence of spatial autoregression in the hedonic income model, which is accounted for by incorporating a spatial component into the regression model. The results provide unique empirical findings about determinants of veterinarian income and spatial patterns, as well as insight useful for governments and academic institutions planning programs and the veterinarian industry.

A STRUCTURAL-EQUATION GME ESTIMATOR AgEcon
Marsh, Thomas L.; Mittelhammer, Ronald C.; Cardell, N. Scott.
A generalized maximum entropy estimator is developed for the linear simultaneous equations systems model. We provide results on large and small sample properties of the estimator. Empirical results illustrate efficiency advantages of the generalized maximum entropy estimator proposed in this study over traditional estimators (e.g., 2SLS and 3SLS).

ADAPTIVE TRUNCATED ESTIMATON APPLIED TO MAXIMUM ENTROPY AgEcon
Marsh, Thomas L.; Mittelhammer, Ronald C..
An adaptive estimator is proposed to optimally estimate unknown truncation points of the error support space for the general linear model. The adaptive estimator is specified analytically to minimize a risk function based on the squared error loss measure. It is then empirically applied to a generalized maximum entropy estimator of the linear model using bootstrapping, allowing the information set of the model itself to determine the truncation points. Monte Carlo simulations are used to demonstrate performance of the adaptive entropy estimator relative to maximum entropy estimation coupled with alternative truncation rules and to ordinary least squares estimation. A food demand application is included to demonstrate practical implementation of the...

Show Quality Quarter Horse Auctions: Price Determinants and Buy-Back Practices AgEcon
Taylor, Mykel R.; Dhuyvetter, Kevin C.; Kastens, Terry L.; Douthit, Megan; Marsh, Thomas L..
This study estimates the price determinants of show quality quarter horses sold at auction. Several characteristics including genetic and physical traits, quality of pedigree, and performance record of the horse, as well as the horse's offspring, were found to significantly impact selling price. Sale order positively affected price and appears to be driven by buyers rather than intentional ordering of the horses. A common practice at horse auctions is for the seller to reject the final bid offered and buy back the horse. Model-predicted prices for these buy-back horses indicate they are not undervalued by the final bids, based on their characteristics.

Input Quality in the Sugar Beet Industry AgEcon
Boland, Michael A.; Marsh, Thomas L..
Using 23 years of data (1978-2000), this study examines seven vertically integrated sugar beet plants representing three different companies in the United States. The objective of this research is to identify the marginal costs of producing sugar beets for vertically integrated sugar beet processors as a way of determining the cost savings from higher quality sugar beets. In doing so, we account for quality differences in the sugar beet input that are used to manufacture the refined sugar output. The results quantify links between high quality sugar beets and lower processing costs.

ENDOGENOUS PROTECTION IN THE MEXICAN CORN AND SORGHUM MARKET AgEcon
Marshall, Maria I.; Marsh, Thomas L..
Trade relations between the United States (U.S) and Mexico are increasingly interrelated and important ever since the ratification of NAFTA in 1994. With the advent of NAFTA, tariffs on many agricultural products were lowered or are in the process of being lowered. Mexico implements a tariff-rate quota for corn which is to be phased out by 2009. This quota is divided among the various Mexican corn importers with "cupos", which are import permits. Import permits are administrative trade barriers that can be defined as any obstacle that appears and disappears as market conditions change. It is widely recognized in the literature that administrative trade barriers create numerous obstacles to the international exchange of agricultural products. In this...
