Adults and teenagers were surveyed to determine their use and ownership of 32 consumer, business, and entertainment technology devices. Demographics, technology experience, and “technophobia” were examined as potential discriminators between Confident Users, Hesitant Users, and Nonusers of each technological device. Results indicated that older, technophobic adults with little computer training and lower income, black and Hispanic, technophobic teenagers did not use most technological devices. 相似文献

The effects of consumer education and information treatments on choice of alternative products are described. Knowledge of upholstery serviceability and flammability before and after these treatments is measured as well as simulated purchase behavior of 448 Canadian consumers. Subjects show an increase in knowledge between pre- and posttests. The choice of fire resistant upholstery differs among consumer information treatments but not among education treatments. The policy implications of these findings are discussed. 相似文献

A logistic regression analysis is used to assess the impact of the wife's income, wage rate, and hours worked on changing from rental tenure to home ownership among a subsample of husband-wife house-holds from the Panel Study of Income Dynamics. Age of the wife, education of the wife, family size, and residence in the Northeast are significant predictors of change in tenure status between 1979 and 1983; of the wife's employment variables tested, only the number of hours worked (a proxy for labor force commitment) is a significant predictor of the probability of changing from rental tenure to home ownership. 相似文献

The present study supplements Canadian consumer expenditure survey data with unique time use data to analyze family life cycle decisions regarding allocation of full income to market purchased consumption goods, home production, and leisure time. Results confirm that young children's presence causes families to increase their shares of full income allocated to home production and to decrease the shares of full income allocated to leisure. As a share of full income, expenditures for market goods steadily increase while expenditures for women's home production diminish as children age. 相似文献
