THE APPLE JUICE CONCENTRATE ANTI-DUMPING CASE AGAINST CHINA: AN ESTIMATE OF CHANGE IN WASHINGTON'S REVENUES
Provedor de dados: 31
Autores: van Voorthuizen,   Hilde; Cho,   Sung-Yeol; Schotzko,   R. Thomas; Mittelhammer,   Ronald C.
Increasing volumes of apple juice concentrate imports from China into the U.S. began in the mid 90s as a result of low Chinese prices.  In 1999, the U.S. Apple Association launched a complaint with the US International Trade Commission (USITC) regarding the Chinese price strategy.  During the course of investigation, the U.S. Apple Association requested that the Department of Agricultural Economics at Washington State University analyze the impact on the total value of juice apples utilized in Washington during the span of the USITC investigation.  To determine the magnitude of the effect of the USITC investigation, not only on finished apple juice prices but also on the Washington raw product price, an inverse demand for finished product and an input...

MEASURING THE IMPACT OF ADVERTISING AND PROMOTION: SINGLE-OR MULTI-EQUATION SYSTEMS? A CASE STUDY OF THE WASHINGTON APPLE INDUSTRY
Provedor de dados: 31
Autores: van Voorthuizen,   Hilde; Schotzko,   R. Thomas; Mittelhammer,   Ronald C.
This paper reports the results of a case study analyzing the impacts of promotion and advertising conducted by the Washington Apple Commission (WAC) using both single- and multi-equation systems.  The analyses are compared in terms of the comparability and coherency of results and in terms of the types of information that can be generated by the multi-equation model but not by the single-equation model.  Due to the availability of detailed data from the WAC, the multi-equation system incorporates measures of actual lines of print media within an explicit model of print media as well as a measure of the multiplier effect associated with WAC promotion expenditures relative to the overall (retail-matched) level of print media.  This information cannot be...

AN IMPERFECTLY COMPETITIVE MARKET MODEL OF THE U.S. LETTUCE INDUSTRY
Provedor de dados: 31
Autores: Hammig,   Michael D.; Mittelhammer,   Ronald C.
An econometric model was specified to represent the U.S. lettuce industry. Cursory examination of the industry structure suggests that imperfect competition may prevail in the lettuce market. Therefore, relations were specified that allowed for the possibility of imperfectly competitive behavior to affect market equilibrium outcomes. Specifically, a supply price equation was specified to account for the influence of market power of large growers, particularly during seasons of geographically concentrated production. Results do not contradict the hypothesis that imperfect competition exists in the lettuce market.

Bayesian Analysis of a Japanese Meat Demand System: A Robust Likelihood Approach
Provedor de dados: 31
Autores: Heckelei,   Thomas; Mittelhammer,   Ronald C.; Wahl,   Thomas I.
This paper presents an application of Bayesian analysis to an AIDS model of Japanese meat demand extending previous approaches in three ways: (1) The methodology employed is robust with respect to the likelihood function but retains the generic, easily programmable character of algorithms offered by Monte Carlo Integration approaches based on the normal likelihood function. (2) In addition to inequality constraints, linear exact restrictions and stochastic prior information are subjected to a Bayesian posterior analysis of validity and incorporated into Bayesian point estimates of model parameters and elasticities. (3) In order to assess the influence of the prior density on posterior distributions of model parameters relative to the likelihood, a measure...

MARKET SEGMENTATION WITHIN CONTINGENT VALUATION
Provedor de dados: 31
Autores: Grimsrud,   Kristine M.; Mittelhammer,   Ronald C.
A finite probability mixture model is combined with a contingent valuation model to analyze the existence of differential market segments in a hypothetical market. The approach has at least two principle benefits.  First, the model is capable of identifying market segments within the hypothetical market.  Second, the model can be used to estimate WTP/WTA within each segment.  The model is illustrated using a data set collected on consumer response to genetically modified foods in Norway.

INVESTING IN FARM WORKER HOUSING: A MULTI-SEASON PEAK-LOAD ANALYSIS OF WASHINGTON STATE DATA
Provedor de dados: 31
Autores: Qenani-Petrela,   Eivis; Wandschneider,   Philip R.; Mittelhammer,   Ronald C.; McCluskey,   Jill J.
This paper develops cost effective investment rules for farm worker housing and applies the model to farm worker housing in the state of Washington.  The state must meet varying seasonal farm worker housing needs at minimum expense.  In this study we examine investment rules to choose among different housing technologies in order to minimize the total costs of housing consistent with achieving welfare goals.  The research extends existing peak-load models to the multi-season planning cycle case and applies the approach empirically to a new subject area.

Permanent Housing for Seasonal Workers? A Generalized Peak Load Investment Model for Farm Worker Housing
Provedor de dados: 31
Autores: Qenani-Petrela,   Eivis; Mittelhammer,   Ronald C.; Wandschneider,   Philip R.
Many seasonal workers are housed in transitory accommodations, including tents and vehicles. In this study, we analyze the supply side of this problem by assuming that a public agent must house the workers through direct public investment. A peak load model is adapted to develop investment rules for the least-cost provision of seasonal worker housing, adding an interacting multi-season component to existing models. Based on this model and the data from three prototype projects, the majority of the least-cost investment would be in permanent, but seasonally occupied, housing.

REGIONAL AND NATIONAL IMPACTS OF EXPANDED PACIFIC NORTHWEST POTATO PRODUCTION
Provedor de dados: 31
Autores: Estes,   Edmund A.; Blakeslee,   Leroy L.; Mittelhammer,   Ronald C.
A 46-equation econometric model of the U.S. potato market was developed. The model examines the determination of planted acreage, yield, production, and farm prices in the Pacific Northwest and in five other producing regions which compete with Northwest production. National demand relationships for potatoes used in processing, fresh consumption and livestock feed are also specified. These estimated relationships are used to simulate future scenarios which assume alternative rates of expansion for Northwest potato production. Results suggest that opportunities for considerable expansion of Northwest potato production exist if the secular shift in potato demand continues and increases in acreage are not excessive or expansion does not occur too quickly.

AN EMPIRICAL BARGAINING MODEL OF PRICE DISCOVERY: AN APPLICATION TO THE WASHINGTON/OREGON ASPARAGUS INDUSTRY
Provedor de dados: 31
Autores: Folwell,   Raymond J.; Mittelhammer,   Ronald C.; Wang,   Q.
The bargaining process and its role in price discovery within the Pacific Northwest asparagus industry is analyzed using a general empirical bargaining model.  Growers' and processors' inverse supply and demand functions define boundaries for the negotiated prices.  OLS and Heckman's two-stage estimation procedures are used to estimate a stochastic bargaining model of price determination.  The results indicate that basic supply and demand forces exert substantial influences on the bargaining process.  In particular, expected levels of supply play a paramount role in the level of prices offered, while past prices also influence current offers.  The general framework of analysis used in relation to asparagus can be generalized to other commodities where...

ACCOUNTING FOR AGGREGATION BIAS IN ALMOST IDEAL DEMAND SYSTEMS
Provedor de dados: 31
Autores: Mittelhammer,   Ronald C.; Shi,   Hongqi; Wahl,   Thomas I.
This study revisits the consistent aggregation (over households) property of almost ideal demand system (AIDS) models and presents a method to explicitly account for expenditure aggregation bias when estimating the aggregate AIDS model with time-series data. Ignoring aggregation bias can lead to biased and inconsistent parameter estimates and can cause aggregate demand functions to be inconsistent with the demand functions at the individual household level. Recognizing the general limited information contained in aggregate time-series data for explicitly modeling aggregation bias, we present a new method of constructing an aggregation bias term that is derived from the proportions of household in different income groups. This information is generally...

A BAYESIAN ALTERNATIVE TO GENERALIZED CROSS ENTROPY SOLUTIONS FOR UNDERDETERMINED ECONOMETRIC MODELS
Provedor de dados: 31
Autores: Heckelei,   Thomas; Mittelhammer,   Ronald C.; Jansson,   Torbjorn.
This paper presents a Bayesian alternative to Generalized Maximum Entropy (GME) and Generalized Cross Entropy (GCE) methods for deriving solutions to econometric models represented by underdetermined systems of equations. For certain types of econometric model specifications, the Bayesian approach provides fully equivalent results to GME-GCE techniques. However, in its general form, the proposed Bayesian methodology allows a more direct and straightforwardly interpretable formulation of available prior information and can reduce significantly the computational effort involved in finding solutions. The technique can be adapted to provide solutions in situations characterized by either informative or uninformative prior information.

This paper makes a contribution to the application of nonlinear simultaneous equations estimation and nonparametric Bootstrapping techniques. The nonlinear demand model estimation work in this paper is in the context of the newly developed Quadratic Almost Ideal Demand System (QUAIDS) model, and provides substantive results in terms of both model estimation technique and empirical economic findings. For the first time, bootstrapping is used in this highly nonlinear modeling environment to estimate variability in demand model parameter estimates and associated demand elasticities. The application relates to Japanese consumer behavior relative to Wagyu Beef, Imported Beef, Pork, Chicken, and Fish demand, and the empirical results are highly relevant to U.S....

ADAPTIVE TRUNCATED ESTIMATON APPLIED TO MAXIMUM ENTROPY
Provedor de dados: 31
Autores: 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...

AN OPTION VALUE APPROACH TO VALUING PRESERVATION PROPERTIES
Provedor de dados: 31
Autores: Winfree,   Jason A.; McCluskey,   Jill J.; Mittelhammer,   Ronald C.
There has been a recent trend towards purchasing land for farmland preservation, wildlife refuges, other conservation, and cultural and historical preservation. There is a great deal of unexplained variation in the dollars paid per acre for these properties. The theoretical basis for this analysis is an option value model with stochastic returns to development. The data used in our analysis is sales transactions data for natural resource conservation and farmland preservation purposes from throughout the United States. We find that land, when it would be best used for development, but is not developed, has a significantly higher price.

This paper considers estimation and inference for the multinomial response model in the case where endogenous variables are arguments of the unknown link function.   Semiparametric estimators are proposed that avoid the parametric assumptions underlying the likelihood approach as well as the loss of precision when using nonparametric estimation.  A data based shrinkage estimator that seeks an optimal combination of estimators and results in superior risk performance under quadratic loss is  also developed.

A Semi-Parametric Basis for Combining Estimation Problems Under Quadratic Loss

Autores: Judge,   George G.; Mittelhammer,   Ronald C.
When  there  is  uncertainty  concerning  the  appropriate  statistical  model  to  use  in  representing the data sampling process and corresponding estimators, we consider a basis for optimally combining estimation  problems.    In the context of the multivariate linear  statistical model, we consider a semi-parametric  Stein-like (SPSL) estimator, ...that shrinks to a random data-dependent vector and, under quadratic loss, has superior performance relative to the conventional least squares estimator. The relationship of the SPSL estimator to the family of Stein estimators is noted and risk dominance extensions between correlated estimators are demonstrated.  As an application we consider the problem of a possibly ill-conditioned design matrix and devise...

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.

An analytical framework to assess the effects of changing income and socio-demographic distributions on aggregate food demand functions in transitional economies is presented. Ignoring such distributional effects can lead to biased estimates of aggregate demand elasticities. The proposed method is applied to Chinese urban household expenditure survey data. The results indicate that the drastic distributional changes that have occurred in China have had notable effects on estimated demand elasticities for both food and non-food commodity groups.

Autores: Mittelhammer,   Ronald C.; Judge,   George G.
The Cressie-Read (CR) family of power divergence measures is used to identify a new class of statistical models and estimators for competing explanations of the data in binary choice models. A large flexible class of cumulative distribution functions and associated probability density functions emerge that subsumes the conventional logit model, and forms the basis for a large set of estimation alternatives to traditional logit and probit methods. Asymptotic properties of estimators are identified, and sampling experiments are used to provide a basis for gauging the finite sample performance of the estimators in this new class of statistical models.

We assess consumer choice of eco-labeled, organic, and regular apples, and identify sociodemographic characteristics affecting the choice among those three alternatives.  Eco-labeled apples are less desirable than organic when food safety, the environment, and children's needs are considered.  Characteristics that may be expected to positively affect the decision to buy eco-labeled apples relative to regular apples actually have the opposite effect with the inclusion of the organic alternative.  When considering all three choices, the eco-labeled product is found to be an intermediate choice among consumers.

This paper introduces a new class of estimators based on minimization of the Cressie-Read (CR) power divergence measure for binary choice models, where neither a parameterized distribution nor a parameterization of the mean is specified explicitly in the statistical model. By incorporating sample information in the form of conditional moment conditions and estimating choice probabilities by optimizing a member of the set of divergence measures in the CR family, a new class of nonparametric estimators evolves that requires less a priori model structure than conventional parametric estimators such as probit or logit. Asymptotic properties are derived under general regularity conditions and finite sampling properties are illustrated by Monte Carlo sampling...

This paper presents empirical evidence concerning the finite sample performance of conventional and generalized empirical likelihood-type estimators that utilize instruments in the context of linear structural models characterized by endogenous explanatory variables. There are suggestions in the literature that traditional and non-traditional asymptotically efficient estimators based on moment equations may, for the relatively small sample sizes usually encountered in econometric practice, have relatively large biases and/or variances and provide an inadequate basis for estimation and inference. Given this uncertainty we use a range of data sampling processes and Monte Carlo sampling procedures to accumulate finite sample empirical evidence concerning...

We investigate oligopolistic competition between U.S. and Chinese apple exporters in the ASEAN market using strategic trade theory and the NEIO literature.  We also analyze competition in the U.S. and Chinese domestic markets.  U.S. supplies higher quality apples to ASEAN than China, resulting in product differentiation.  The results show that U.S. exporters had a higher markup than Chinese exporters through the 1990s; however, as the share of Chinese apples expanded, the U.S. markup declined and the Chinese markup increased dramatically.  Competitive pricing prevails both in the U.S. and Chinese domestic markets.

This paper makes two principal contributions: first, we propose a method for representing well-being aggregates and estimating population subgroup decompositions when data is available on population distributions across subgroups; second, we analyze the Quality of Life (QOL) of 'poor' and 'non-poor' population segments of 86 countries for the years 1980s and 1990s. The three major findings of this paper are as follows: First, nearly every well-being indicator declines as poor's population share increases; second, evidence of a significant difference in the QOL-poor's population share relationship between Asian and nonAsian countries is present for only few QOL indicators. In other words, the tendency for QOL to decline with increasing poor's population...

SEASONAL OLIGOPOLY POWER IN THE D'ANJOU PEAR INDUSTRY
Provedor de dados: 31
Autores: Winfree,   Jason A.; McCluskey,   Jill J.; Mittelhammer,   Ronald C.; Gutman,   Paula.
We estimate seasonal oligopoly power at a disaggregated variety level in the D'Anjou pear market. Our data spans 1993 to 2000, during which time imported pears became more prevalent in the U.S. market. The range of monthly industry-conduct-parameter magnitudes is 0.034 to 0.195 and is most pronounced when the fresh D'Anjou pear crop first becomes available in the earliest months of the marketing year. Possible reasons for timing of oligopoly power relate to the growth of imported pears during the latter portion of marketing year. In addition, oligopoly power may diminish during the marketing year as pears in storage decline in quality.

DISTRIBUTION OF HUMAN DEVELOPMENT, CHILD LABOR AND POVERTY IN INDIA
Provedor de dados: 31
Autores: Rahman,   Tauhidur; Mittelhammer,   Ronald C.
This paper contributes to the growing debate on regional economic inequality and polarization in India. The specific objectives of this paper are to: (1) analyze regional development disparities amongst various states in India to determine if they are on a convergent course; (2) analyze the evolution of regional inequalities amongst states with respect to a number of socioeconomic indicators and factors that have been suggested to affect the incidence of child labor; (3) investigate and test empirically whether polarization is taking place in Indian states; and (4) investigate whether regional indices of human development and child labor incidence follow similar patterns. Using a consistent data series and applying a number of recently developed measures,...

A LATENT VARIABLE MIMIC APPROACH TO INFERRING THE QUALITY OF LIFE
Provedor de dados: 31
Autores: Rahman,   Tauhidur; Mittelhammer,   Ronald C.; Wandschneider,   Philip R.
This paper makes three principal contributions. First, we propose a new estimator for the unobservable variable models with endogenous causes. We show that under factor analysis type of assumptions, Robinson and Ferrara (1977)'’s procedure is not fully efficient, and a more efficient procedure can be obtained by merging Robinson and Ferrara'’ procedure with that in Joreskog and Goldberger (1975) procedure. The asymptotic properties of the new estimator are compared with these two estimators and results indicate that, with our mixture approach, significant efficiency gains can be achieved. Second, we model the Quality of life (QOL) as an unobservable or latent link variable between observable causes and observable effects, which mitigates problem of bias,...

INFORMATION THEORETIC ALTERNATIVES TO TRADITIONAL SIMULTANEOUS EQUATIONS ESTIMATORS IN THE PRESENCE OF HETEROSKEDASTICITY
Provedor de dados: 31
Autores: 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.

Semiparametric Estimation and Inference in Multinomial Choice Models
Provedor de dados: 31
Autores: Fahs,   Rafic; Cardell,   N. Scott; Mittelhammer,   Ronald C.
The purpose of this paper is to incorporate semiparametric alternatives to maximum likelihood estimation and inference in the context of unordered multinomial response data when in practice there is often insufficient information to specify the parametric form of the function linking the observables to the unknown probabilities.  We specify the function linking the observables to the unknown probabilities using a very general flexible class of functions belonging to the Pearson system of cumulative distribution equations.  In this setting we consider the observations as arising from a multinomial distribution characterized by one of the CDFs in the Pearson system.  Given this situation, it is possible to utilize the concept of unbiased estimating functions...

A MATRIX OF DEMAND ELASTICITIES FOR FRESH FRUIT
Provedor de dados: 31
Autores: Price,   David W.; Mittelhammer,   Ronald C.
A matrix of direct, cross and income demand elasticities at farm level for 14 fresh fruits was estimated using the mixed estimation technique. Prior estimates were derived from past research and application of the symmetry relation, cross induction and subjective judgment. There were no statistically significant conflicts between the sample and prior information. Even though estimation efficiency increased with the mixed technique, only a limited number of cross elasticities could be estimated.

SEMIPARAMETRIC BAYESIAN ANALYSIS OF SIMULTANEOUS SYSTEMS WITH AN APPLICATION TO JAPANESE MEAT DEMAND
Provedor de dados: 31
Autores: Xi,   Jing; Heckelei,   Thomas; Mittelhammer,   Ronald C.
This paper motivates and applies a variant of the Bayesian Bootstrap Multivariate Regression by Heckelei and Mittelhammer (2003) to a Japanese meat demand specification with endogenous regressors.  The methodology is first given an alternative and more elegants motivation and then extended to incorporate microtheoretic restrictions and to apply in the context of a simultaneous equation models. The results of the application are compared to results based on an earlier approach used by Heckelei, Mittelhammer, and Wahl (1996).

Risk Aversion, Prudence, and the Three-Moment Decision Model for Hedging
Provedor de dados: 31
Autores: Chen,   Xiaomei; Wang,   H. Holly; Mittelhammer,   Ronald C.
The linear two-moment mean-variance (MV) model has been widely used in finance and economic decision analysis as an approximation of Von Neumann-Morgenstern expected utility (EU) model.  The introduction of third or higher moments not only can improve the accuracy of the approximation, but is also suitable to represent investors¡¯ skewness preference (prudence) with the latter supported by empirical evidence.  The goal of this paper is to develop a general MVS model and compare it and the traditional MV model against the EU model in the setting of an individual producer hedging in the futures market.  Results show: 1) the derived linear MVS model maintains the analytical convenience of MV model, 2) it can generate different results as MV, 3) it approximate...

Measuring the Impact of Globalization on the Well-being of the Poor: Methodology and an Application to Africa
Provedor de dados: 31
Autores: Rahman,   Tauhidur; Mittelhammer,   Ronald C.
Whereas a large number of empirical studies have been devoted to analyzing the relationship between measures of income and globalization (defined by openness to international trade), much less attention has been paid to the analysis of well-being for the various subgroups of population and their causal associations with globalization. To address this gap in the literature, this paper first analyzes the quality of life (QOL) of 'poor' and 'non-poor' population segments of 40 African countries over a period of 1980-2000, and then examines their causal association with openness to trade. In order to understand the impact of openness to trade on the well-being of poor, we assume the causal chain Openness„_ Income„_ Poverty„_ Well-being of poor and empirically...
