FACTORS INFLUENCING CHANGES IN POTATO AND POTATO SUBSTITUTE DEMAND
Provedor de dados: 31
Autores: Richards,   Timothy J.; Kagan,   Albert; Gao,   Xiaoming.
Despite the rapid rise in complex carbohydrate consumption over the last twenty-five years, fresh potato consumption has fallen by over 50%.  Fresh potato growers and retailers alike need to know whether these changes reflect consumer responses to changing relative prices or incomes, or whether they are due to changes in consumer tastes.  This paper uses a linear approximation almost ideal demand system (LA/AIDS) to investigate the effect of relative prices, expenditures, and a set of socioeconomic variables on complex carbohydrate demand.  Estimation results show that the socioeconomic variables explain some of the changes in demand, but a significant amount remains as evidence of a change in consumer tastes.

Advertising and Retail Promotion of Washington Apples: A Structural Latent Variable Approach to Promotion Evaluation
Provedor de dados: 31
Autores: Richards,   Timothy J.; Gao,   Xiaoming; Patterson,   Paul M.
"Commodity promotion" consists of many activities, each designed to contribute to a consumer's product knowledge or influence tastes. However, both knowledge and tastes are unobservable, or latent, variables influencing demand. This paper specifies a dynamic structural model of fresh fruit demand that treats promotion and other socioeconomic variables as "causal" variables influencing these latent variables. Estimating this state-space model using a Kalman filter approach provides estimates of both the system parameters and a latent variable series. The results show that these latent effects contribute positively to apple and other fruit consumption, while reducing banana consumption.

Modeling consumer's perception of orange juice
Provedor de dados: 31
Autores: Gao,   Xiaoming; Lee,   Jonq-Ying.
A multiple indicator and multiple cause model with dichotomous indicators was used to study consumer's perception toward orange juice.  Results indicate that recalls of orange juice advertising messages by the respondent had a positive impact on his/her perception toward orange juice.  Results also suggest that selected socioeconomic variables were important determinants of consumer perception.

DOUBLE-HURDLE MODEL WITH BIVARIATE NORMAL ERRORS: AN APPLICATION TO U.S. RICE DEMAND
Provedor de dados: 31
Autores: Gao,   Xiaoming; Wailes,   Eric J.; Cramer,   Gail L.
Per capita rice consumption in the U.S. has doubled over the past decade. The effects of social and demographic variables on the household's rice consumption decisions are analyzed along with income and price variables. A double-hurdle model is used to solve simultaneously the consumer decisions whether to purchase rice and how much. The joint decision hypothesis is tested and accepted. The non-normal distribution of error terms may be responsible for possible bias in the empirical test of the joint decision hypothesis. The hyperbolic sine transformation is used to correct the problem in this study prior to testing the joint decision hypothesis.

The Development of the GDPs of the G-7 Countries, 1950-1988
Provedor de dados: 31
Autores: Gao,   Xiaoming; Moss,   Charles B.; Theil,   Henri; Weatherspoon,   Dave D.
Data from the International Comparison Project are used to analyze the development of the real gross domestic products (GDPs) of the G-7 countries from 1950-1988.  For the group as a whole, per capita GDP increased almost threefold in this period, whereas the inequality among the seven countries decreased dramatically.

A BIO-ECONOMIC DYNAMIC PROGRAMMING ANALYSIS OF THE SEASONAL SUPPLY RESPONSE BY FLORIDA DAIRY PRODUCERS
Provedor de dados: 31
Autores: Gao,   Xiaoming; Spreen,   Thomas H.; Delorenzo,   Michael A.
Seasonal price premiums have been proposed as a means of dampening the highly seasonal patterns of milk production in Florida. A Markov decision bio-economic model of the breeding and replacement decisions was solved via stochastic dynamic programming and used to analyze the potential supply response to seasonal price premiums. The results of the analysis suggest that the seasonal milk supply in Florida is highly price inelastic.

A general differential demand model for mixed quantity- and price-dependent equations
Provedor de dados: 31
Autores: Brown,   Mark G.; Lee,   Jonq-Ying; Gao,   Xiaoming.
A mixed demand system is developed using the fundamental matrix equation of demand theory.  The model parameterization combines the parameterizations of the quantity- and price- dependent Rotterdam models.  The relationship between the mixed-demand-model parameters and the underlying direct and indirect utility functions allows analysis of various separability assumptions.
