THE ECONOMIC CAUSES OF OBESITY: A SURVEY

Abstract.  Obesity rates have increased dramatically over the last 30 years. Rising obesity has developed into a considerable worldwide public health problem with significant economic and social consequences. Accordingly, obesity has become a subject of economic research. This paper provides a broad survey of the recent and growing economic literature on the causes of obesity. The literature, both theoretical and empirical, overall aims to explain the rising obesity trend and to identify the factors that contribute to obesity. Also surveyed are non-economic causes and consequences of obesity and the interconnection with economic influences. An understanding of the causes of obesity allows policies to be considered that might stem the global increase in obesity.     

The impact of children on women managers' career behavior and organizational commitment

Having children has been assumed to reduce womens' organizational commitment and involvement in their work and increase their likelihood of turnover. This assumption was examined by comparing 169 women MBAs who had children with 191 who did not on the basis of their responses to a survey. After controlling for differences in age, experience and work status, results showed no differences in met expectations, turnover intentions, commitment, satisfaction, job characteristics, or perceptions of progress. However, women with children scored lower on job involvement and reported fewer work hours. While parenting demands may affect these variables, they may not necessarily affect work-related attitudes, professional attainment, attachment to the job, or commitment to the organization. © 1995 by John Wiley & Sons, Inc.     

Junk-food,home cooking,physical activity and obesity: The effect of the fat tax and the thin subsidy

In an effort to reduce the growing prevalence of obesity, a tax on junk-foods, known as ‘fat tax’, has been proposed, the revenue from which could be used to finance a ‘thin subsidy’ for healthy foods or exercising equipment. The present paper addresses the fat tax and thin subsidy within a food-intake rational-choice model. Assuming that healthy meals are cooked at home with purchased ingredients and time input, the paper examines the effects on obesity of a tax on junk-food meals and a subsidy to cooking ingredients, distinguishing between a weight-conscious and a non-weight conscious individual, and between a weight-conscious individual who is physically active and physically inactive. The results show that for a non-weight conscious individual a fat tax will unambiguously reduce obesity, whereas a thin subsidy may increase obesity. However, for a weight-conscious individual, particularly one who is physically active, even a fat tax may increase obesity, as it may reduce not just the consumption of junk-food, but also the time devoted to physical activity. The paper explores conditions under which obesity will rise, fall, or remain intact following the introduction of a fat tax or a thin subsidy.
