A nice suit is one that compares favorably with those worn by others in the same local environment. More generally, a positional good is one whose utility depends strongly on how it compares with others in the same category.1A positional externality occurs when new purchases alter the relevant context within which an existing positional good is evaluated.2 For example, if some job candidates begin wearing expensive custom-tailored suits, a side effect of their action is that other candidates become less likely to make favorable impressions on interviewers. From any individual job seeker's point of view, the best response might be to match the higher expenditures of others, lest her chances of landing the job fall. But this outcome may be inefficient, since when all spend more, each candidate's probability of success remains unchanged. All may agree that some form of collective restraint on expenditure would be useful.In such cases, however, it is often impractical to negotiate private solutions. Do positional externalities then become legitimate objects of public policy concern? In attempting to answer this question, I employ the classical libertarian criterion put forth by John Stuart Mill3, who wrote the state may not legitimately constrain any citizen's freedom of action except to prevent harm to others. I argue that many positional externalities appear to meet Mill's test, causing not just negative feelings but also large and tangible economic costs to others who are ill-equipped to avoid them. I also discuss an unintrusive policy remedy for positional externalities, one modeled after the use of effluent charges to curb environmental pollution.The paper is organized as follows. Section 1 notes the deep similarity between the conditions that give rise to positional arms races and those that give rise to conventional military arms races. Section 2 follows with a review of evidence concerning the strength of concerns about relative position. Section 3 describes some of the tangible economic costs that people experience as a result of positional externalities arising from such concerns. Section 4 takes up the question of whether collective action directed against positional externalities is consistent with respect for individual rights. Section 5 describes how a progressive consumption tax could neutralize many of the most costly effects of positional externalities. 相似文献

We re-examine some of the standard axioms used in the literature on poverty measurement. Using a sample of 486 students from Australia, Israel and the USA we investigate the extent to which individuals' perceptions of poverty correspond to the axioms. We find that axioms such as anonymity, growth of the poor and monotonicity are resonably well supported. However there is very little support for the focus axiom and the principle of transfers was the least well supported of the eight specific criteria for poverty measurement that we examined. 相似文献

We point out that fiscal multipliers derived from SVAR-models include the predicted future path of policy instruments. After the initial shock, net taxes and government expenditures react to each other and are autocorrelated. In a counterfactual simulation, we report fiscal multipliers that abstract from these dynamic responses. 相似文献

This study presents how Hydro-Quebec manages its short-term financial risks. The quantitative hedging model is articulated over forward and volatility premia and constrained by a yearly risk limit provided by the firm's Finance Committee. The hedging solutions provide the optimal linear hedging parameters and option strike levels. The second part of the paper is devoted to a theoretical analysis of the sensitivity of the optimal solutions to changes in the premia, by means of the general implicit function theorem. 相似文献

On the basis of historical data aggregated over the period 1973 to 2000, we have experimented with four different approaches to estimate the synthetic euro's equilibrium exchange rate. Using a number of competing models with the same data set, variable definitions and sample period offers the possibility to assess the uncertainty surrounding such equilibrium levels, both from an empirical (different estimates) and a theoretical viewpoint (different specifications). In this exercise, the 'Rest of the World' is proxied by the US, the UK, Japan and Switzerland, aggregated on the basis of trade weights.
We employed reduced form co–integration models, a structural VAR, a NATREX model (estimated in structural form) and the ECB's small–sized euro area wide macro–econometric model. In this order the approaches feature an increasing degree of 'structure', in the sense of the constraints based on economic theory embedded in the econometric models that were estimated. The results confirm the high likelihood for the euro having been undervalued in Q4 2000, while stressing the significant empirical and theoretical uncertainty with respect to the equilibrium exchange rate level. 相似文献

This research note involves an investigation of some conceptual issues which arise in the coexistence of direct and indirect forms of participation in three case studies of South African organizations. It is concluded that a managerial paradigm shift from a strong individualistic orientation towards collaborative or collective values could facilitate the process of achieving both economic growth and equity in the workplace.

This paper discusses the entrepreneurial landscape in Africa and locates a new generation of African entrepreneurs and their business networks within it. Unlike others in that landscape (i.e. micro- or small-scale informal sector vendors, and traditional or multinational large-scale formal sector firms), the ‘new generation’ entrepreneurs are business globalists who organized a system of business enterprise networks consisting of national, regional, and pan-African organizations. The study analyses interview data from 57 men and women network members from 10 countries (Botswana, Ethiopia, Ghana, Kenya, Mali, Senegal, South Africa, Uganda, Zambia, and Zimbabwe). Some defining characteristics of these entrepreneurs are interactive social and business relationships, use of modern management methods and information technology, trust among fellow members, transparent business practices, advocacy on behalf of the private sector, and commitment to increasing intra-African commerce. Their mission is to improve the climate for private sector business in Africa and to promote regional economic integration. They pursue cross-national commercial ventures, maintain official observer status at established regional economic organizations, sign memoranda of understanding with multilateral agencies, establish venture capital funds, and help to change government policies. The paper identifies characteristics of the ‘new generation’ entrepreneurs, evaluates goals and achievements of their networks, and concludes that despite limitations, these entrepreneurs and their organizations have created intra- and cross-national networks that strengthen private-sector-led economic growth in Africa. 相似文献

Within the recent literature on the geography of new firm formation, much attention is given to the role of regional knowledge sources based on the Knowledge Spillover Theory of Entrepreneurship. At the same time, several other studies show the importance of agglomeration economies for new firm formation. The goal of this study is to assess the relative importance of these determinants for differences in the share of employment creation from new firms at the level of municipalities for the period of 1999–2006 in the Netherlands. It is found that the traditional drivers of new firm formation, such as economic growth and agglomeration effects, have a much stronger effect on new firm formation compared to measures of the regional knowledge base. Moreover, it is shown that when not correcting for the presence of agglomeration effects, the role of local knowledge resources is easily over-estimated, pointing to the dangers of misspecifications of models. The results imply that the knowledge spillover theory of entrepreneurship should, at least for the Netherlands, not be exaggerated. 相似文献
