We consider the well-known theorem of Alchian and Allen that adding a per unit charge to the price of two substitute goods increases the relative consumption of the higher price good. The current literature misspecifies the conditions under which the theorem holds. When applying the theorem the fixed cost should be applied on a per unit basis, rather than in terms of an entry fee for consumption. We state the necessary conditions for the theorem to hold when the consumers are shipped to the goods.  相似文献

Parental alcohol consumption is often associated with an increased likelihood of child abuse. As consumption is related to price, the purpose of this paper is to investigate the propensity for increases in the full price of alcohol to influence entry rates and the length of time spent in foster care. Using alcoholic beverage prices and a measure of availability in combination with data on foster care cases, we find that higher alcohol prices are not effective in reducing foster care entry rates; however, once in foster care, the duration of stay may be shortened by higher prices and reduced availability.  相似文献

Interventions across all sectors in fragile states are called to contribute to tackling conflict and fragility despite the lack of evidence on how/if this is possible. This article reviews the existing literature to identify five entry points through which water supply and sanitation service delivery might interact, both positively and negatively, with state‐building and/or peace‐building processes. Evidence for the relevance of these entry points was assessed in the Republic of South Sudan and the Democratic Republic of Congo. Our research suggests that the way in which water and sanitation services are delivered is more important than the delivery of these services per se. Moreover, we find that the effects are largely modest and likely to be localised, and that greater attention is still needed to avoid potential negative consequences.  相似文献

Auction design with endogenous entry is complicated by entry coordination among bidders due to multiple entry equilibria issue. This article studies auction design when information acquisition costs are private information of bidders. We show that this problem can be resolved by sufficient dispersion in these costs. First, we find that a simple second‐price auction with no entry fee and a reserve price equal to the seller's valuation is ex ante efficient, while a revenue‐maximizing auction involves personalized entry fees, which are determined by the hazard rates of their information acquisition cost distribution. Second, we show that sufficient dispersion in the information acquisition costs (more dispersion than a particular uniform distribution by the Bickel‐Lehman dispersive order) can coordinate bidders and implement uniquely the desirable entry. The dispersion in information acquisition costs is also necessary for this “unique implementation” result. (JEL D44, D82)  相似文献

Policy‐making in relation to sustainable development is usually at the national (or, in relation to climate change, the global) level, yet the consumption it seeks to modify takes place at the household level. If households all ‘made ends meet’ in the same way then the much‐relied‐upon notion of per capita consumption would be valid and we could use ‘top‐down’ modelling to guide policy. Cultural Theory, however, predicts that there are five socially viable ways of making ends meet, and that all of them will be found (in varying proportions) within any nation. This prediction has been tested on a sample of 220 British households and shown to be well supported. Top‐down modelling, it is argued, has to give way to constructive interplay between the reflexive policy‐maker and a plurally responsive citizenry.  相似文献

Policies to encourage carpooling in high‐occupancy vehicle (HOV) lanes have been adopted in the United States to lower congestion and reduce air pollution. We analytically model highway congestion and other vehicle‐related externalities. Encouraging carpooling decreases total costs when congestion relief in mainline lanes outweighs increased HOV lane congestion. Importantly, entry of new drivers via induced demand can negate the benefits of increased carpooling. Using 10 years of traffic data from Los Angeles we estimate time and route‐specific marginal external costs. Because costs vary substantially across routes, hours, and days, current policies to promote carpooling will often increase social costs. (JEL R41, R48, Q53)  相似文献

The paper reviews the assembly of the Country Code and its wider project circulated to reify a particular construction of countryside citizenship. The Code can be read as an attempt to pursue a particular moral project and an effort to influence behaviour through the design of a particular regime of conduct. Numerous alterations, most recently in 2004, have not fundamentally changed the aims of the Code as first introduced in 1951; as such the new Code marks not a withdrawal from the attempted imposition of a uniform countryside citizenship but rather an extension and refinement of this project and a continuing influence on the production and consumption of rural space. It is argued that the revisions and wider changes in associated materials and mediation of the Code are indicative of the way that countryside politics is changing to reflect both a post-productivist and post-feudal countryside: a shift that is being performed on the part of government through a more managerialist and interventionist style of governance.  相似文献

As opportunities to gamble proliferated rapidly during the 1990s, accessibility to gambling facilities has been cited as a factor driving increased gambling consumption. However, research examining this relationship is limited. Most assessments have tended to be at a broad regional rather than a local level. Furthermore, explanations for why greater access encourages increased gambling activity have been inadequate. Using the framework of time-geography, this paper outlines new empirical evidence to assist in clarifying relationships between the accessibility to and consumption of gambling. Data on gambling behaviour were obtained from 1,018 persons in seven residential centres of the Richmond-Tweed region of NSW, Australia and compared to local provision of gambling facilities. In this study, availability of gambling opportunities—measured here by electronic gaming machines (EGMs) per capita—is often reflected in differences in gambling activity by the local population. It is concluded that accessibility to EGM facilities at a particularly local level is an important factor driving their use.  相似文献

SUMMARY. With the anticipated introduction of a triple vaccine that protects against measles, mumps and rubella, the proportion of children vaccinated each year will need to rise from 68 per cent to 95 per cent if the target of eliminating measles is to be achieved. This article reviews the morbidity associated with preventable infectious diseases of childhood, discusses possible reasons for inadequate vaccine uptake and suggests ways for improving this situation including the case for school entry legislation.  相似文献

The authors evaluated a protocol to screen and provide brief interventions for alcohol problems to college students treated at a university hospital emergency department (ED). Of 2,372 drinkers they approached, 87% gave informed consent. Of those, 54% screened positive for alcohol problems (Alcohol Use Disorders Identification Test score < or = 6). One half to two thirds of the students who screened positive drank 2 to 3 times a week, drank 7 or more drinks per typical drinking day, or had experienced alcohol dependence symptoms within the past year. Ninety-six percent of screen-positive students accepted counseling during their ED visit. Three quarters of those questioned at 3-month follow-up reported that counseling had been helpful and that they had decreased their alcohol consumption. The prevalence of alcohol problems, high rates of informed consent and acceptance of counseling, and improved outcomes suggest that the ED is an appropriate venue for engaging students at high risk for alcohol problems.  相似文献

Abstract In this article I explore a theoretical link between return visits and return migration using ethnographic data obtained through fieldwork among members of the broader Commonwealth Eastern Caribbean community in Toronto, Canada. Return visits are periodic but temporary sojourns made by members of migrant communities to their external homeland or another location where strong social ties exist. As a result, the conceptual framework in this article revolves around transnationalism as the return visit is shown to be a transnational exercise that may facilitate return. Using data from ethnographic fieldwork, three themes highlight the link between return visits and return migration: (1) the need to facilitate ties such that relationships are meaningful upon permanent return; (2) the functional nature of the return visit, such that changes are measured and benchmarked against what is remembered and internalized by the migration after the migration episode; and (3) the knowledge that return visits aid in reintegration.  相似文献

Foster care is a source of significant costs to both governments and foster children. Policies that provide income support to households potentially reduce entry into foster care via reducing child maltreatment and improving child behavior. As part of the American Recovery and Reinvestment Act in 2009 (ARRA2009), the federal government expanded the earned income tax credit (EITC), which is an important income support program for low-income working households. Using state-level data, we investigate the impact of this EITC expansion on state-level foster care entry rates. Typically, states with state-level EITC match federal EITC spending at a specific rate, meaning that increases in federal EITC spending increase state-level spending as well. We find that expansion of EITC decreased foster care entry rates by 7.43% per year in states with a state-level EITC, relative to those without. In models that separately examine foster care entry rates by age of the child, we find that the ARRA2009 had different effects on foster care entry based on the child’s age. We find that ARRA2009 decreased foster care entry rates for children age 11–15 by nearly 12% in states with a state EITC and it decreased foster care entry rates for children age 16–20 by roughly 17% in states with a state EITC, relative to states without a state EITC.  相似文献

For ergonomic purposes it is useful to quantify the energy expenditure and the level of physical activity imposed on workers. Oxygen consumption (VO?) is often used to calculate energy expenditure and can be used as an indication of physical activity. Twenty-five subjects participated in the study. Oxygen consumption (VO?) in L O?/min and heart-rate (HR) in beats per minute (bpm) were simultaneously measured during different work tasks at each individual's workplace. Ninety-one different work tasks with light or moderate physical activity were included (physical activity was classified by the VO? measurements). Estimated oxygen consumption (L O?/min) was then calculated by using the HR measurements in bpm combined with individual HR-VO? equations established in a laboratory. Although heart-rate based estimations of individual oxygen consumption showed relatively low precision, heart-rate measurements in combination with individual exponential HR-VO? equations can be used to discriminate between work involving light physical activity and work involving moderate physical activity.  相似文献

This article provides an introduction to, and makes a case for, cultural intermediaries as an entry point for the study of media and cultural production. We offer a strategic parsing of the conceptual foundations provided by Bourdieu with regard to cultural intermediaries and the media, loosely organized in terms of where they are located (working in media); the means of accomplishing their role (working with media); and their economic role in promoting consumption (the work of mediation). We then follow the translation of the concept from Bourdieu to a cultural economy approach that is concerned with the material practices involved in the formation of value. A review and comparison of substantive findings from a range of cultural economic case studies of cultural intermediary occupations serves as an introduction to a three-fold approach that might guide future studies of occupations in cultural industries, in terms of: historicizing occupations, material practices, and assessments of impact. Finally, we conclude with a claim for the utility of ‘cultural intermediaries’ as a way to think about cultural production, and highlight areas in which work remains to be done.  相似文献

Portal surveys, defined as assessments occurring proximal to the entry point to a high-risk locale and immediately on exit, can be used in different settings to measure characteristics and behavior of attendees at an event of interest. This methodology has been developed to assess alcohol and other drug (AOD) use at specific events and has included measuring intentions to use collected at entry and reported use on exit, as well as chemical tests for AOD consumption at both entrance and exit. Recent applications of the portal survey procedure to electronic music dance events that occur in established venues (e.g., bars or nightclubs) are discussed.  相似文献

Social capital, networks and leisure consumption   总被引:2,自引:0,他引:2  
This article reflects on the way in which personal ties affect the nature and content of consumption. While it is banal to observe that friends, kin, colleagues and neighbours influence anyone's pattern of consumption, comparatively little work exists on how this process operates. The article will be illustrated by some secondary analysis of the British Household Panel Survey which has a panel of approximately 10,000 people who have been interviewed annually since 1991. It analyses aspects of individual consumption in relation to people's associational involvement and friendship ties. The data is explored in the context of debates about social capital, attempting to apply the concept in order to analyse recreational practices. It is suggested that social capital is a flawed concept and that greater appreciation of the complexity and diversity of network ties is required to understand how personal connections influence consumption.  相似文献

Abstract We consider here the energy consumption characteristics of migrants and nonmigrants in two northern Wisconsin counties characterized by relatively rapid growth as areas of retirement and recreational activities. Migrants from metropolitan areas use more electricity when measured at the meter and report driving more. Both of these differentials are sustained even after controlling for personal and behavioral variables, appliance ownership, and type of energy use. Metropolitan migrants do not spend more for space heating, although there is again a positive effect on space heating energy consumption net of the other variables. We conclude that metropolitan migrants make an energy impact on the area, due in part, to their characteristics, housing, and type of energy consumption, but also because of differences in the way they use energy. In these ways they add an element of heterogeneity to the rural community, as well as increased demand for energy consumption.  相似文献

This article discusses the data on international migration to the UK, their limitations, and their origins. No 1 source gives a demographically satisfactory account of net migration, and different sources of data are not compatible with each other. Their present form can only be understood in the context of a reluctant acceptance, in the face of domestic political pressure, of the need to impose the same controls on the entry of Commonwealth citizens from 1962-1971 as had been imposed on the entry of aliens since 1920. Coleman asserts that UK migration statistics suffer 1 major omission and several systematic deficiencies. The omission is the absence of any information, either from the International Passenger Survey (IPS) or from the Home Office, on gross or net migration flows to the UK from the Republic of Ireland. Neither the IPS nor the Home Office data provide a very satisfactory form of measurement of other migration streams. Neither has much time depth, the former not existing before 1963, the latter being affected by changes in rules and procedures. As a voluntary sample with only relatively few interviews per year on intended migrants, the IPS can only provide a crude overall estimate of the general demographic import of migration flows, incapable for statistical reasons of any refined sub-division or analysis, and prove both to error and bias. The Home Office statistics do not treat immigration in a demographically useful way. They measure flows only in 1 direction, provide no demographic or socioeconomic characteristics on those accepted for settlement, and are not compatible with the IPS in most ways. For political reasons, no action to resolve the Irish anomaly is likely, especially when the trend is for less, not more, control and counting on the entry of European Community citizens.  相似文献

Commodities in action: measuring embeddedness and imposing values   总被引:1,自引:0,他引:1  
Recent approaches in political economy look at the effects of technology and social values on economic action. Combining these approaches with those of economic anthropologists, this article poses that the way the economy is instituted can be understood by looking at reasons actors have for participating in actor‐networks of production, distribution and consumption. Using the author's research on American recycling, this article first shows that much of the‘making’or instituting of the economy happens outside the market, through political machinations, contracts and standards. Second, it suggests that these relationships impose value upon goods differently than do market relations. The details of the recycling‘chain’show the ways actors shape the network and demonstrate that the social values that add‘economic value’to goods are not uniform, but are highly contextual. Starting from Mark Granovetter's notion of 'social embeddedness', the article explains that the measure of social embeddedness is not as important as the values imposed upon other actors through social structure in the economy. It calls for a close observation of economic action in the locales within which production takes place to understand better the‘actions‐at‐a‐distance’where the politics of technology, social movements and power create the empirical, instituted economy.  相似文献

This article utilizes the findings of a recently completed,eight-country research project to visit some key issues in thetheory and practice of gender mainstreaming. The research resultsindicate that gender mainstreaming is a diverse entity whenlooked at from a cross-national perspective but rather hollowwhen considered within the national setting. To the extent thatthere is a "common core" to gender mainstreaming in action acrosscountries, it lies in the tendency to apply the approach ina technocratic way and to be nonsystemic in compass. The argumentis advanced that this is at least in part attributable to particularitiesin the development of mainstreaming. The article suggests thatgender mainstreaming is underdeveloped as a concept and identifiesa need to elaborate further on some fundaments. In particular,the conceptualization of mainstreaming needs to be rethoughtwith special attention devoted to the understanding of the problematicof gender inequality that underlies it and the articulationof the relationship between gender mainstreaming and societalchange.  相似文献
