A Binary-Ordered Probit Model of Cigarette Demand AgEcon
Kasteridis, Panagiotis P.; Munkin, Murat K.; Yen, Steven T..
This study analyzes the demand for cigarettes fitting observed zero outcomes with a trivariate model consisting of an equation for the starting smoking decision, an equation for the quitting decision, and an equation that models the level of cigarettes consumed. Five competing specifications are considered to explain level, with the ordered probit, which accommodates pile-ups of counts in the dependent variable, providing the best fit. Marginal effects of explanatory variables are calculated providing strong evidence of race and gender differences in consumption patterns. The estimated marginal effects are robust to alternative categorizations of the level of cigarettes.

A SAMPLE SELECTION APPROACH TO CENSORED DEMAND SYSTEMS AgEcon
Yen, Steven T.; Lin, Biing-Hwan.
A censored demand system estimator is proposed by extending the sample selection model of Heckman. Censoring is governed by a selection mechanism which avoids the restricitve Tobit parameterization. Results of application to household consumption of beverages suggest the estimator produces slightly different elasticity estimates from the Tobit estimator. Demands for beverages are nearly unitary elastic, and net substitution is an obvious pattern.

An Analysis of Demand Elasticities for Fluid Milk Products in the U.S. AgEcon
Davis, Christopher G.; Blayney, Donald P.; Cooper, Joseph C.; Yen, Steven T..
This study examines retail fluid milk products purchase data from Nielsen 2005 home scan data. The demand for seven categories of fluid milk products were estimated: whole milk, whole flavored milk, reduced fat milk, flavored reduced fat milk, buttermilk, canned milk and all other fluid milk products. Analyses of the purchases of seven fluid milk categories based on the Nielsen 2005 home scan retail data are used to determine the roles marital status, age, race, education, female employment status and location play in the empirical estimations of aggregate demand elasticities. To derive the demand elasticities, a censored translog demand system is used. The results reveal that price and income are the main determinants of demand for fluid milk products...

AN ECONOMETRIC ANALYSIS OF DONATIONS FOR ENVIRONMENTAL CONSERVATION IN CANADA AgEcon
Yen, Steven T.; Boxall, Peter C.; Adamowicz, Wiktor L..
As provincial governments in Canada trim budgets, fewer funds are available for environmental conservation programs. Many jurisdictions are letting private interests and/or users of the resource base help fund conservation projects. Thus funding for conservation is becoming more dependent on donations to environmental causes either through direct giving of funds or through memberships in organizations. This study explores some determinants of private contributions to environmental conservation activities through an econometric analysis of donations and memberships relating to wildlife habitat protection and enhancement. We use data from a 1991 survey conducted in the three prairie provinces that provides information on donation behavior, income,...

Childhood Malnutrition In China: Change Of Inequality In A Decade AgEcon
Chen, Zhuo; Eastwood, David B.; Yen, Steven T..
A concentration index methodology to analyze the inequality in childhood malnutrition in China is outlined. Height-for-age z score is used as a measure of childhood malnutrition. Using household survey data from nine Chinese provinces, it is found that per-capita household income, household head's education, urban residence and access to a bus stop reduced malnutrition. Child's age had a nonlinear effect on the malnutrition status. Income growth and access to public transportation reduced the inequality, while rural-urban gap, provincial differentiation, and unequal distribution of household head's education increased inequality in childhood malnutrition. Gender is not a factor in either malnutrition status or inequality. Investments in infrastructure and...

Complements and Meat Demand in the U.S. AgEcon
Davis, Christopher G.; Stefanova, Stela; Hahn, William F.; Yen, Steven T..
In this study we estimated the price elasticities among meats, vegetables, grains, and potatoes and the impact that different levels of income have on the demand for these commodities. The 2005 Nielsen retail home scan data were used to construct a censored demand system of 14 equations. Results revealed that the uncompensated cross-price elasticities for both low and high-incomes suggest both substitution and complement relationships, while the compensated price elasticities are dominated primarily by substitution relationships. Our findings also revealed that expenditure elasticities among both low and high-income households differ for most commodities.

Consumer Demand for Meat Cuts and Seafood AgEcon
Davis, Christopher G.; Lin, Biing-Hwan; Yen, Steven T..
Household at-home consumption of different types and cuts of meat and fish products is investigated by estimating a large censored demand system with a two-step procedure using ACNielsen's Homescan data. We find different price and expenditure elasticities between low-income and high-income households. High income households are less responsive to price changes, and the substitution patterns also differ between the low- and high-income households. Whereas the uncompensated elasticities suggest a mixture of gross substitutes and complements among the products for both low- and high-income households, the compensated elasticities suggest net substitution is the obvious pattern for the low-income households.

Consumer Knowledge and Meat Consumption in the US AgEcon
Lin, Biing-Hwan; Yen, Steven T.; Davis, Christopher G..
We investigate the roles of consumer knowledge and sociodemographic factors in the consumption of meat products at home and away from home, using data from the Continuing Survey of Food Intakes by Individuals and its companion Diet and Health Knowledge Survey conducted by the US Department of Agriculture. The sample used contains individuals not consuming some of the products. In addition, diet knowledge is potentially endogenous because it is likely to be affected by unobserved factors which also affect meat consumption. It is well known that traditional estimation procedures not accounting for censored dependent variables or simultaneity produce biased estimates. These econometric issues are addressed by developing a simultaneous -equations system,...

Consumer Knowledge, Food Label Use and Grain Consumption AgEcon
Lin, Biing-Hwan; Yen, Steven T..
Responding to mounting evidence of the association between whole-grain consumption and a reduced risk of heart problems and other diseases as well as body weight maintenance, the U.S. Government has strongly encouraged its citizens to increase consumption of whole grains. However, compared against the 2005 Federal dietary recommendations, in 1994-96 only 6 percent of Americans met the current recommended whole-grain consumption. To narrow this huge gap between actual and recommended consumption of whole grains, an effective nutrition education campaign is needed. A demand system with two censored consumption equations and two endogenous knowledge and attitude variables is estimated to investigate the factors that affect the consumption of whole and refined...

Consumer Preferences for Refrigerators Manufactured by “Climate Leaders” AgEcon
Li, Xiaogu; Clark, Christopher D.; Jensen, Kimberly L.; Yen, Steven T..
In 2002, EPA established a voluntary program called the Climate Leaders Program (CL Program) designed for organizations to complete a corporate greenhouse gas (GHG) inventory, set a goal for reducing GHG emissions, and achieve that goal. The program was never implemented as a product labeling program. In 2010, EPA announced the program’s phase out. This study examines whether the CL Program could have been effectively used as a consumer product labeling program to assist consumers in choosing products manufactured by firms that have voluntarily set and achieved targeted GHG emission reductions.

Consumption of Pork Products: Now and to the Year 2020 AgEcon
Davis, Christopher G.; Lin, Biing-Hwan; Yen, Steven T..
Data from the recent USDA'’s food consumption surveys are used to describe pork consumption patterns, to estimate a censored demand system for pork cuts, and to forecast pork consumption. Results indicate that between 2000 and 2020, pork consumption is predicted to grow for all cuts mainly due to population growth.

Consumption of Pork Products: Now and to the Year 2020 AgEcon
Lin, Biing-Hwan; Davis, Christopher G.; Yen, Steven T..
Data from the U.S. Department of Agriculture’s 1994-96 and 1998 Continuing Survey of Food Intakes by Individuals (CSFII) are used to describe pork consumption patterns as well as to estimate a censored demand system for pork cuts. The descriptive analysis fills the void about basic information on who consumes pork, how much, and where. A censored system of four pork cuts is estimated for adults, using a maximum-likelihood procedure. The estimated system is used to predict consumption of pork products by adults through the year 2020.

CROSS-SECTIONAL ESTIMATION OF U.S. DEMAND FOR BEEF PRODUCTS: A CENSORED SYSTEM APPROACH AgEcon
Yen, Steven T.; Huang, Chung L..
Demands for beef products are investigated using the U.S. Department of Agriculture’'s 1987-88 Nationwide Food Consumption Survey data. The censored translog demand system is estimated with full-information and simulated maximum-likelihood procedures. These procedures represent different approaches to evaluation of multiple probability integrals in the likelihood function, but produce very similar parameter and elasticity estimates. Findings suggest sociodemographic variables play important roles in the demand for beef, and that demand for different cuts of beef should be treated differently.

DEMAND FOR DIFFERENTIATED VEGETABLES AgEcon
Yen, Steven T.; Lin, Biing-Hwan; Harris, James Michael; Ballenger, Nicole.
To obtain a healthier diet, Americans need to consume not only more vegetables, but also a healthier mix of vegetables. Household demands for eight categories of vegetables are investigated, using ACNielsen's Homescan data. A maximum simulated likelihood estimation procedure results in elasticity estimates which are somewhat larger than those obtained from both time-series and cross-section data in the literature. Even these larger elasticities are not large enough to bridge the dietary consumption gap without, and possibly even with, substantial price or food expenditure subsidies. Furthermore, Homescan data do indicate some significant differences in preferences for types of vegetables by household characteristics, such as race and ethnicity. This...

Demand for Organic and Conventional Fruits AgEcon
Lin, Biing-Hwan; Yen, Steven T.; Huang, Chung L..
We examine consumer demand for organic and conventional fruits by estimating a censored demand system, using Nielsen's Homescan data. Sociodemographic characteristics and income are found to be significant factors of organic fruit consumption. Consumers are responsive to own-price changes in selected organic fruits, while the own-price elasticities for conventional fruits are much smaller. Asymmetric cross-price effects are found between organic and conventional fruits, suggesting that a change in relative prices will more likely cause consumers of conventional fruits to "cross-over" to organic fruits, while the reverse is less likely to happen such that organic consumers will "revert" to conventional fruits.

DETERMINANTS OF CONSUMER AWARENESS OF FOODBORNE PATHOGENS AgEcon
Lin, Chung-Tung Jordan; Jensen, Kimberly L.; Yen, Steven T..
Each year, microbial pathogens cause millions of cases of foodborne disease and result in many hospitalizations and deaths. Effective consumer education programs to promote safer food handling practices and other averting behaviors may benefit from consumer awareness of microbial pathogens. This paper investigates U.S. consumers’' awareness of four major microbial pathogens (Salmonella, Campylobacter, Listeria and E. coli) as food safety problems, using a multinomial probit model. The awareness varies among pathogens and the variations appear to be related to differences in the number and severity of illnesses associated with these pathogens. Our findings suggest that awareness of microbial pathogens is associated with food safety perceptions, awareness of...

Determinants of Household Expenditures on Alcohol AgEcon
Yen, Steven T.; Jensen, Helen H..
This paper examines the determinants of household alcohol expenditures by using a nonnormal and heteroscedastic double-hurdle model to accommodate zero observations in the sample. The model is a generalization of the double-hurdle model estimated in previous studies of alcohol consumption. We also examine the effects of explanatory variables by calculating and decomposing the elasticities. Findings support the use of a more generalized error distribution. Income, region, education, and household demographics are among the significant determinants of alcohol expenditures.

DETERMINANTS OF PARTICIPATION AND CONSUMPTION: THE CASE OF CRAWFISH IN SOUTH LOUISIANA AgEcon
Yen, Steven T.; Dellenbarger, Lynn E.; Schupp, Alvin R..
This study investigates the determinants of crawfish consumption in South Louisiana using a generalized limited dependent variable model that accounts for both participation and consumption decisions. Income, Catholic, white, and household size increase the likelihood of crawfish consumption but not the conditional level of consumption. Education and employment status are among the other household characteristics that determine the conditional level of consumption.
