Soft drink consumption has been hypothesized as one of the major factors in the growing rates of obesity in the United States. Nearly two-thirds of all states currently tax soft drinks using excise taxes, sales taxes, or special exceptions to food exemptions from sales taxes to reduce consumption of this product, raise revenue, and improve public health. In this paper, we evaluate the impact of changes in state soft drink taxes on body mass index (BMI), obesity, and overweight. Our results suggest that soft drink taxes influence BMI, but that the impact is small in magnitude. ( JEL I18, H75) 相似文献

The necessity of institutional proposals on the stable development of rural territories is justified in the article. A multivariant
approach is proposed for studying the institutional environment of the countryside. The key trends of reformation of the countryside’s
social and economic systems are defined based on the results of the our own empiric research. 相似文献

Catharsis theory is regarded as refuted. This widespread belief can be questioned for two reasons. First, most test films used in experimental studies do not meet the requirements of catharsis theory; second the social consequences of catharsis were not measured. Two films were produced for our experiment, one which meets the requirements of catharsis theory and should reduce aggressiveness and one which, according to alternative theories, should increase aggressiveness. A control group saw a neutral film. As dependent variables (a) level of general aggression, (b) aggressive inclinations in social situations, and (c) willingness to use aggressive stereotypes were measured. The film that was assumed to reduce aggressiveness increased aggressiveness even more than the film that was assumed to increase it. This surprising finding and its consequences are discussed. 相似文献

Abstract Globalization is commonly defined as a strict economic path by most previous works, but it is really a fuzzy concept with unrestrained dimensions. While the ideological location of an incumbent political party is a powerful predictor of its policy position, the role of a political party in the globalization-growth nexus has never been fully empirically investigated. By applying Pedroni's panel cointegration technique instead of a time-series or traditional panel data approach, this paper aims to empirically re-examine the co-movement and the causal relationship among economic growth, the overall globalization index, and its three main dimensions—economic, social, as well as political integrations—by using panel data for 23 Organization for Economic Cooperation and Development (OECD) countries for 1970 to 2006. Certainly, the political party variable is taken into account as the advanced test is promoted, and we finally discover that all variables move together in the long run. Based on the results of the panel causality test, though the evidence of short-run causality is very weak, it does show long-run unidirectional causality running from the overall index of globalization, economic globalization, and social globalization to growth. Finally, the critical role of the political party is deeply discussed in relation with our results. 相似文献

This paper shows the results of an exploratory analysis of the structure of a complex product category: Wine. In complex categories, a usual strategy of consumers is the partitioning of alternatives into homogeneous subsets and the sequential eliminations of subsets until a product/brand is chosen from among few homogeneous alternatives in the last subset. To identify if there is such a kind of strategy and the product attributes involved is of great interest for the retailer. After a discussion of the different modelling alternatives of the choice process, the authors provide an application of the additive trees (ADDTREE) model to explore the hierarchical structure. The ADDTREE results provide a first overview of the competitive market structure of the wine category: competition becomes more intense as the wine category is partitioned by, first, the type of wine criteria and, second, the designation of origin (DO) criteria. 相似文献

This paper identifies factors associated with takeoff—a sustained period of high growth following a period of stagnation. Countries that experience takeoffs average 2.3% annual growth following their stagnation episodes, while those that do not average 0%. Using probit, we find that de jure trade openness is positively and significantly associated with takeoffs. A one‐standard‐deviation increase in de jure trade openness is associated with a 55% increase in the probability of a takeoff in our default specification. Capital account openness encourages takeoff responses, but measures of de facto trade openness are found to be poor predictors of takeoffs. We also examine the determinants of nations achieving “sustained” takeoffs; i.e. those lasting eight years or longer. Takeoffs in countries with more commodity‐intensive output bundles are less likely to be sustained, suggesting that adverse terms‐of‐trade shocks may play a role in ending long‐term high growth episodes. 相似文献

Consumer involvement is an established priority in UK health‐ and social‐care service development and research. To date, little has been published describing the process of consumer involvement and assessing ‘consumers’ contributions to research. This paper provides a practical account of the effective incorporation of consumers into a research team, and outlines the extent to which they can enhance the research cycle; from project development and conduct, through data analysis and interpretation, to dissemination. Salient points are illustrated using the example of their collaboration in a research project. Of particular note were consumers' contributions to the development of an ethically enhanced, more robust project design, and enriched data interpretation, which may not have resulted had consumers not been an integral part of the research team. 相似文献

This article explores the change in the level of competition in rural banking markets after the deregulation that occurred following passage of the Riegle‐Neal Act of 1994. Using an empirical model that utilizes both the number of banks and the value of deposits in a cross‐section of 278 rural markets, we decompose the impact of the entry of new banks into resulting changes in per capita demand and the costs/profits of local banks in 1994 and 2004. The results support the view that local banking markets have become more competitive since the mid‐1990s. 相似文献
