Abstract . Hypothesized direct and interaction relationships among the dependent variable willingness to pay more taxes for support of live artistic communications media and the independent variables of past attendance, education, income, leisure time, and liberalism-conservatism are tested. Past enjoyment probably makes people more favorable to tax support. Social policy implications of the results are discussed.  相似文献

随着中国的崛起,中国和世界上唯一的超级大国美国之间的国力差距在缩小。不少观察家担心,武装冲突将随之发生。在近代历史上,出现过七次大国崛起,挑战现存强国,其中六次都导致了冲突。但是,本文指出,有理由相信,中国的崛起将是和平的。  相似文献

As tariffs have fallen, it is apparent that trade costs are a significant obstacle to international trade and that they vary from country to country. The gap between the cif and fob value of a trade flow is a useful measure of aggregate trade costs, but only if the measure is based on a consistent volume of trade; mirror statistics are unsuitable. Using high quality Australian import data disaggregated at the HS 6-digit level, we find large country-by-country variations in trade costs. Distance, weight and size account for part of the variation in trade costs. Indicators of institutional quality pick up some of the variation in trade costs, but the relationship is not uniform across mode of transport and commodities; exporting countries’ institutional quality is more strongly related to trade costs for air freight than sea freight, and the relationship is commodity-specific and strongest for manufactured goods. Country-specific characteristics influencing trade costs provide a link between institutions and economic development.  相似文献

Experimental work in economics prompted the development of theories of other‐regarding behavior. In this article we reanalyze two classic public goods experiments and focus on the nature of individuals' responses to others' behavior in order to help distinguish alternative motives for giving, including altruism, warm glow, reciprocity, and inequality aversion. Analysis that allows for asymmetric feedback responses generates support for inequality aversion motives but little for reciprocity (matching), altruism, and warm glow. We conclude that individual‐level analysis of existing public goods data can provide more insightful, informative estimates of treatment effects.  相似文献

Overreaction to Fearsome Risks   总被引:1,自引:0,他引:1  
When risks threaten, cognitive mechanisms bias people toward action or inaction. Fearsome risks are highly available. The availability bias tells us that this leads people to overestimate their frequency. Therefore, they also overreact to curtail the likelihood or consequences of such risks. More generally, fear can paralyze efforts to think clearly about risks. We draw on a range of environmental risks to show the following: (1) Fear leads us to neglect probability of occurrence; (2) As fearsome environmental risks are usually imposed by others (as externalities), indignation stirs excess reaction; (3) We often misperceive or miscalculate such risks. Two experiments demonstrate probability neglect when fearsome risks arise: (a) willingness-to-pay to eliminate the cancer risk from arsenic in water (described in vivid terms) did not vary despite a 10-fold variation in risk; (b) the willingness-to-accept price for a painful but non dangerous electric shock did not vary between a 1 and 100% chance. Possible explanations relate to the role of the amygdala in impairing cognitive brain function. Government and the law, both made by mortals and both responding to public pressures, similarly neglect probabilities for fearsome risks. Examples relating to shark attacks, Love Canal, alar and terrorism are discussed.  相似文献

In this paper, we develop a paleoeconomic model of the co-evolution of economic specialization and encephalization—the common physiological measure of intelligence as reflected by brain mass relative to total body mass. Our economic analysis links ecological and social intelligence theories of increased encephalization in early hominins through a model in which both economic and ecological feedbacks jointly determined the evolutionary incentives. We focus on degrees of specialization affected by coordination costs with and without market exchange. Our results suggest encephalization would be a process characterized by diminishing returns to behavioral advances. In terms of the long-running debate in economics over whether specialization increases or decreases intelligence, our results suggest from an evolutionary perspective the answer depends on economic/social institutions and how these influence ecological interactions.  相似文献
