A theory of persistent income inequality   总被引:7,自引:4,他引:7  
This paper explores the dynamics of income inequality by studying the evolution of human capital investment and neighborhood choice for a population of families. Parents affect the conditional probability distribution of their children's income through the choice of a neighborhood in which to live. Neighborhood location affects children both through local public finance of education as well as through sociological effects. These forces combine to create incentives for wealthier families to segregate themselves into economically homogeneous neighborhoods. Economic stratification combines with strong neighborhoodwide feedback effects to transmit economic status across generations, leading to persistent income inequality.  相似文献

The remarks that follow are made with regard to the behavior of leaders whose self-image is threatened by a variety of conditions comprising the world problematique. Of all those conditions, surely those associated with violence and warfare are the most threatening. I would speculate, therefore, that what I've written here is especially pertinent for deliberations on how to encourage peace and disarmament.While these remarks are focused on the behavior of leaders—especially those in government—they can hold, too, for those in the public who identify with those leaders…itself another psychodynamic process. Of course, the public's contexts differ so the degree of threat and response will differ, too. This is a matter for further attention.Moreover, self-images are usually rich in content and while some aspects are threatened, others may not be or, indeed, may be attracted by new rational ideas. The resultant struggle within the psyche complicates the overt expression of these unconscious conflicts.But these dynamics mirror those comprising the problematique, especially its expression around issues of war and peace. Therefore, psychodynamic matters deserve as much attention and utilization as we now give to conventional, indeed, often ritual means, masquerading as rationality, for dealing with violence and armaments.  相似文献

As the hunting, butchering, processing, and consumption of bushmeat is a potential source of human Ebola virus (EV) infections, the extent to which bushmeat is a substitute for food produced and sold in the formal sector suggests that the relative price of food could matter for the incidence of human EV infections. This paper considers if productivity in the food sector is a driver of human EV infections in sub‐Saharan Africa. We estimate count data specifications of country level human EV infections as a function of food sector productivity in sub‐Saharan Africa over the 1976–2013 time period. Our parameter estimates suggest that if productivity in the food sector was on average 1 per cent higher over the 1976–2013 time period, the incidence of human EV infection would have been 42.5 per cent lower. This is consistent with bushmeat being a substitute for food produced in the formal sector, as food productivity increases lower the price of formal food relative to bushmeat. Our findings suggest that as productivity in the formal food sector is a driver of human EV infections in sub‐Saharan Africa, policy interventions that increase food productivity would enable Millennium Development Goal outcomes related to hunger, disease mitigation, and sustainability of wildlife.  相似文献

The Carpathian Basin is one of the most vulnerable European regions in terms of potential climate change impacts on biodiversity. Its wide range of tourism activities make it uniquely suitable for assessing the effects of climate change on tourism. This research sought to create a Tourism Adaptation Portfolio (TAP) for the Szentendre micro-region in Hungary and to assemble an adaptation toolbox for current and future use by tourism organizations. The TAP contains practical, easy to implement solutions for key stakeholders in the sector by adaptation type (technology, management, behavior, education, policy). Surveys of local tourism suppliers showed that 70% said they were well informed, largely by the Internet, but 55% admitted to not knowing enough. The methodology outlined here is transferable and the process can be replicated elsewhere, supporting other regions in becoming climate-friendly tourism destinations, creating opportunities for uniquely positioning a region for consumers. The article provides a concise overview of tourism provider attitudes assessed through a questionnaire, shedding light on points of intervention, willingness to pay, main barriers and suitable adaptation instruments. The adaptive capacity of stakeholders is also discussed, which is indispensable for implementing successful practices in adaptation and maintaining the current level of environmental services.  相似文献

Risk,uncertainty and the theory of planned behavior: A tourism example   总被引:1,自引:0,他引:1  
The differential impacts risk and uncertainty have on travel decision-making were explored by examining the constructs' influence on the antecedents of intentions to visit Australia using the theory of planned behavior. Respondents were obtained from online consumer panels in South Korea, China and Japan. The South Korean and Chinese samples were general population samples, while the sample from Japan was an international travelers' sample. The extended model fitted the data well, explaining between 21 and 44 percent of the variance in intentions. Subjective norms and perceived behavioral control significantly impacted on intentions in all country samples, whereas attitudes toward visiting Australia were only significant in Japan. Subjective norms influenced attitudes and perceived behavioral control in all country samples. Finally, perceived risk influenced attitudes toward visiting Australia in South Korea and Japan, while perceived uncertainty influenced attitudes toward visiting Australia in South Korea and China and perceived behavioral control in China and Japan.  相似文献

Relationship marketing in consumer markets: Antecedents and consequences   总被引:19,自引:0,他引:19  
Understanding the motivations of consumers to engage in relationships with marketers is important for both practitioners and marketing scholars. To develop an effective theory of relationship marketing, it is necessary to understand what motivates consumers to reduce their available market choices and engage in a relational market behavior by patronizing the same marketer in subsequent choice situations. This article draws on established consumer behavior literature to suggest that consumers engage in relational market behavior due to personal influences, social influences, and institutional influences. Consumers reduce their available choice and engage in relational market behavior because they want to simplify their buying and consuming tasks, simplify information processing, reduce perceived risks, and maintain cognitive consistency and a state of psychological comfort. They also engage in relational market behavior because of family and social norms, peer group pressures, government mandates, religious tenets, employer influences, and marketer policies. The willingness and ability of both consumers and marketers to engage in relational marketing will lead to greater marketing productivity, unless either consumers or marketers abuse the mutual interdependence and cooperation. He has published more than 200 books and research papers in different areas of marketing. His bookThe Theory of Buyer Behavior (1969) with John A. Howard is a classic in the field. He has recently published two scholarly books:Marketing Theory: Evolution and Evaluation (1988) andConsumption Values and Market Choices (1991). He is on the editorial boards of at least a dozen scholarly journals in marketing, international business, and quantitative methods; he is also series editor ofResearch in Marketing (JAI Press). Prior to joining Emory, he was an associate professor of marketing at XLRI Jamshedpur in India. He received his M.B.A. and Ph.D. from Banaras Hindu University, India. He has authored a number of articles in the area of international marketing, business alliances, and environmental marketing. He is coeditor ofResearch in Marketing (Annual Series, JAI Press) and serves on the editorial review board ofInternational Marketing Review.  相似文献
