Water conflicts are intensifying as the population grows in the American West. Stakeholders seek a better understanding of households’ water knowledge, preferences, and willingness to pay (WTP) as they contemplate various water allocation initiatives. An Internet survey provides insight into western households’ perceptions and preferences regarding water use and management, their familiarity with water terminology, and their WTP a fee in support of eight potential water initiatives regarding water acquisition, conservation, and reallocation. Further analysis identifies factors that influence the decision. Just over half of all respondents express a WTP the fee, with an estimated median WTP among survey respondents of $15.65 per summer month. Respondents with higher self-reported water knowledge are more likely to support the fee. The probability of supporting the fee is also influenced by respondents’ demographic characteristics and attitudes toward water scarcity and management. Les conflits liés à l’eau s’intensifient à mesure que la population s’accroît dans l’Ouest américain. Les parties prenantes cherchent à découvrir les connaissances sur l’eau, les préférences et le consentement à payer des ménages étant donné qu’elles envisagent divers schémas d’allocation de l’eau. Un sondage en ligne a donné un aperçu des perceptions et des préférences des ménages de l’Ouest américain concernant l’utilisation et la gestion de l’eau, de leur degré de connaissance de la terminologie de l’eau et de leur consentement à payer une taxe pour appuyer huit projets éventuels d’acquisition, de conservation et de réallocation de l’eau. Une analyse plus détaillée a déterminé les facteurs qui influençaient les décisions. Un peu plus de la moitié des répondants ont indiquéêtre prêts à payer une taxe. Chez les répondants, le consentement à payer médian s’élevait à 15,65 $ par mois durant la saison estivale. Les répondants qui ont indiqué avoir de bonnes connaissances sur l’eau sont plus susceptibles d’appuyer l’imposition d’une taxe. Les caractéristiques démographiques et les attitudes des répondants envers la rareté et la gestion de l’eau influencent la probabilité d’appuyer l’imposition d’une taxe. 相似文献

For three years in Bolivia (2002–2005) the INNOVA Project finished researching several technologies for sustainable agriculture, started by earlier DFID-funded projects. Before INNOVA started critics suggested that these technologies should be discarded in favour of a demand survey. Instead, INNOVA kept the existing technologies, but judged the demand for them with several methods (CIAL, sondeo technology fair, and others). INNOVA found that there was demand for some of the technologies, but that a survey would have missed much of the demand, which is implicit. That is, people are not initially aware of all their problems or of all the possible solutions. Over the years, farmers made more specific, sophisticated demands on the technologies, which evolved as a result. Demand and supply of farm technology are like two sides of an unfolding conversation. 相似文献

Irrigation water productivity in Cambodian rice systems 总被引:1,自引:0,他引:1
Knowledge of the marginal productivity of water is crucial for decisions about its allocation between uses, which is particularly important in the context of increasing competition for water. Using primary, plot‐level panel data, this article estimates the marginal productivity of water from supplementary irrigation in lowland rice systems in Cambodia, taking into account farmer and plot heterogeneity as well as self‐selection of supplementary irrigation. Our estimates indicate a range of elasticities for rice output with respect to water inputs of between 0.057 and 0.069 for wet season production, substantially lower than previous estimates based on either aggregate or trial data. We discuss the policy implications of these results, in particular with respect to the utility of demand management policies and the challenges they pose to the decentralization of water management to Farmer Water Users Groups. 相似文献

The Personality Audit (PA) was developed to meet a need for a relatively simple multiple feedback instrument that could clarify the various motivational needs of executives. Using a psychodynamic approach to leadership, the PA allows the test-taker to assess him- or herself in seven personality dimensions important in human behaviour and to identify personal ‘blind spots’. The resulting insights can be used to formulate appropriate leadership development goals. The objective of this paper is to describe the design and psychometric properties of the PA. This instrument, in contrast with other tools that can be used to clarify the inner theatre of individuals, is designed not only to report information given by the test-taker but also to reflect the perceptions of observers representing both the test-taker's public and private spheres. This paper describes in detail the conceptual foundations of the questionnaire, the psychometric methods used to confirm its validity and reliability, and possible directions for future research. 相似文献

The European Union Eighth Directive on the approval of auditors covers auditor independence only to a very limited extent. The provisions in the five articles on this subject are far less detailed than they were in the drafts of the directive, so that almost all specific regulation is left to the Member States. An examination of the development of the articles dealing with independence and integrity shows how the need to compromise, in order to reach an agreement, frustrated the intentions of the harmonizers. This paper traces the development of the independence rules in the Eighth Directive from the avant projet through the drafts to the final directive. It assesses the extent to which pre-Eighth Directive regulation in the UK and Germany may have affected the directive and then examines the implementation of the directive in the two countries. It concludes that national culture and accounting traditions prevented harmonization of independence rules through the Eighth Directive. 相似文献

Economics was slow to emerge as a distinct academic and professional discipline in the United Kingdom. In the years around 1900, some British universities began to offer degrees in commerce, including accounting. These degrees were influenced by the contemporary emergence of business economics (betriebswirtschaftslehre) in Germany. However, there was no substantive emergence of a body of economic theory relating specifically to the business organization. Later attempts in the 1930s to apply economic argumentation to the problems of business and accounting, in the context of both profit determination and costing, centred around the Department of Business Administration and the Accounting Research Association, based at the London School of Economics. Although the activities of these groups are often viewed in terms of the influence of economics on accounting, there were reverse currents in that accounting notions helped in the formalization of macroeconomic notions such as national income and in the development of social accounting by Richard Stone and others. However, the intervention of the Second World War curtailed this interchange of ideas. In the post-war period, the rapid expansion of accounting as both an academic discipline and a professional practice was accompanied by a greater awareness of economic ideas and concepts. In financial reporting, these had an important influence on the inflation accounting debate of the 1970s and 1980s. In management accounting, economic ideas often operated as criticisms of existing practices. However, both the comparatively underdeveloped application by economists of their theories to business problems and the continuing intellectual barriers between academic and professional accountants made the practical interaction of accounting and economics a sporadic phenomenon. 相似文献

Financial time series are often non‐negative‐valued (volumes, trades, durations, realized volatility, daily range) and exhibit clustering. When joint dynamics is of interest, the vector multiplicative error model (vMEM; the element‐by‐element product of a vector of conditionally autoregressive scale factors and a multivariate i.i.d. innovation process) is a suitable strategy. Its parameters can be estimated by generalized method of moments, bypassing the problem of specifying a multivariate distribution for the errors. Simulated results show the gains in efficiency relative to an equation‐by‐equation approach. A vMEM on several measures of volatility justifies a joint approach revealing full interdependence.

In this paper, we present an economic analysis of CO2-enhanced oil recovery (EOR). This technique entails injection of CO2 into mature oil fields in a manner that reduces the oil's viscosity, thereby enhancing the rate of extraction. As part of this process, significant quantities of CO2 remain sequestered in the reservoir. If CO2 emissions are regulated, oil producers using EOR should therefore be able to earn revenues from sequestration as well as from oil production. We develop a theoretical framework that analyzes the dynamic co-optimization of oil extraction and CO2 sequestration, through the producer's choice of the fraction of CO2 in the injection stream at each moment. We find that the optimal fraction of CO2 is likely to decline monotonically over time, and reach zero before the optimal termination time. Numerical simulations, based on an ongoing EOR project in Wyoming, confirm this result. We also find that cumulative sequestration is less responsive to the carbon tax than to the oil price. Only at very high taxes does a tradeoff between revenues from oil output and sequestration arise. 相似文献

Consequences of free-trade agreements (FTAs) among the ASEAN+3 and ASEAN+6 countries are explored using a dynamic computable general equilibrium (CGE) model. Quantitative assessments of intra- and extra-regional effects on welfare, trade and output are offered. When both trade facilitation and endogenously determined productivity are included in the FTA scenarios, Singapore, other ASEAN countries and China would be able to realize relatively large welfare gains, while the welfare effects on the EU and North America are negligible. The trade and output effects on the latter two regions are also relatively small, with the notable exception of crops, other than rice, in North America. 相似文献
