Upland areas provide UK society with many important functions, goods and services, but have experienced a number of disturbing trends and face an uncertain future. This paper outlines historic, current and future drivers of environmental, economic, socio-cultural and policy change in UK uplands, and assesses how these have affected or are likely to affect ways in which land is used and the provision of ecosystem services. Information is synthesised into scenarios summarising a range of possible futures anticipated for UK uplands to 2060 and beyond. Finally, innovations in science, technology, governance and policy are evaluated that could enable uplands to continue providing key ecosystem services under a range of scenarios. The paper concludes that many upland areas will need to be prepared for significant reductions in grazing and prescribed burning. Conversely, other areas could experience agricultural intensification, for example significant increases in grazing or an expansion of arable or bioenergy crops into upland valleys, due to anticipated increases in global demand for food and energy. These scenarios will take place in the context of climate change. Many may take place together and may interact with each other, with complex and unpredictable implications for the upland environment, economy and society. In this context, a number of advances are needed in science, technology and policy to maintain viable upland communities and the future provision of ecosystem services. These may include funding for ecological and hydrological restoration via carbon offsetting or other means. It may also involve advances in ecosystem service modelling, mapping and valuation, which through stakeholder participation could facilitate more integrated rural planning. New forms of environmental governance need to be explored that can empower those interested in developing upland economies to maintain thriving upland communities, while managing the ecosystem services they provide as efficiently as possible. 相似文献

In recent years India has been moving further in the direction of adopting an Anglo-American model of corporate governance. This decision, the result more of international economic and political pressures than public debate, in effect represents a new development strategy for the world's most populous democracy. In light of this situation, it is important to ask two basic questions: 1) why has the Anglo-American model of corporate governance been adopted? and; 2) can it be justified? This paper addresses the first of these questions by distinguish and examining three historical models of governance in India: 1) the managing agency model in the colonial period; 2) the business house model that emerged after independence, and; 3) the Anglo-American model which has recently been adopted (and is still emerging). The second question is approached through an examination of the "development impact" of the new model, as indicated by such measures as growth, employment and respect for shareholder rights. 相似文献

The boundaries of honesty are the focal point of this exploration of the individualistic origins of modernist ethics and the consequent need for a more pragmatic approach to business ethics. The tendency of modernist ethics to see honesty as an individual responsibility is described as a contextually naive approach, one that fails to account for the interactive effects between individual choices and corporate norms. By reviewing the empirical accounts of managerial struggles with ethical dilemmas, the article arrives at the contextual preconditions for encouraging the development of reflective moral agents in modern corporations. 相似文献

Intervention analysis is proposed as a method for estimating the effects of anti-dumping actions in the presence of a domestic cartel. Data requirements and modelling effort compare favourably with traditional structural model approaches. The method is applied to an anti-dumping action brought to the European Commission and in which the European producers of the product were fined after an anti-cartel action by the Commission covering an overlapping period. Interven tion analysis is applied to distinguish the effects of the anti-dumping action from those of changes in cartel behaviour 相似文献

Hydropower can provide inexpensive, flexible fill-in power to compensate for intermittent renewable generation. Policies for
hydropower dams maintain multiple services beyond electric generation, including environmental protection, flood control and
recreation. We model the decision of a hydroelectric generator to shift some of its power production capacity away from the
day-ahead energy market into a “wind-following” service to smooth the intermittent production of wind turbines. Offering such
a service imposes both private and social opportunity costs. Since fluctuations in wind energy output are not perfectly correlated
with day-ahead energy prices, a wind-following service will necessarily affect generator revenues. Seasonal wind patterns
produce conflicts with the goal of managing rivers for “ecosystem services”—the maintenance or enhancement of downstream ecosystems.
We illustrate our decision model using the Kerr Dam in PJM’s territory in North Carolina. We simulate the operation of Kerr
Dam over a three-year period that features hydrologic variability from normal water years to extreme drought conditions. We
use an optimization framework to estimate reservation prices for Kerr Dam offering wind-following services in the PJM market.
Wind-following may be profitable for Kerr Dam at low capacity levels during some time periods if ecosystems services are neglected
and if side payments, or reserves-type payments, are provided. Wind-following with ecosystem services yields revenue losses
that typically cannot be recovered with reserves market payments. Water release patterns are inconsistent with ecosystem-services
goals when Kerr Dam dedicates significant capacity to wind-following, particularly in drought years. 相似文献

We examine the relationship between housing equity and wage earnings using nine waves of the national American Housing Survey from 1985 to 2003. Employing a rich set of time and place controls, a synthetic mortgage instrumental variable strategy, and a first difference estimator we find that people underwater on their mortgage command a significantly lower wage than other homeowners. The finding survives a number of robustness checks for reverse causality and unobserved heterogeneity. We also explore other determinants of “house lock” including loss aversion, a low existing mortgage interest rate and property tax assessment caps, but do not find these factors mitigate the effect of negative equity on wages. 相似文献

This article reports tests of aggregation over consumer food products and estimates of aggregate food demand elasticities. Evidence that food demand variables follow unit root processes leads us to build on and simplify existing tests of the Generalized Composite Commodity Theorem. We compute food demand elasticities using a method of cointegration that is shown to apply to a convenient but nonlinear functional form. Estimates are based on consumer reported expenditure data rather than commercial disappearance data. 相似文献

The Fair Housing Act of 1968 made discrimination against minorities in the sale or rental of housing illegal. Twenty years
later the Act’s coverage was expanded and its enforcement mechanisms strengthened in response to pressure from fair housing
advocates and evidence of continued segregation and discrimination. Segregation indices and fair housing audits provide measures
of the extent and nature of residential segregation and housing discrimination. High levels of residential segregation suggest
that housing discrimination exists, and audits give a direct measure of the incidence of discrimination. To date, housing
audits consistently show that black auditors encounter discriminatory treatment in the housing search process. Whether the
strengthened enforcement mechanisms of the Act will have a substantial impact on housing market discrimination and, in turn,
residential segregation, remains to be seen. 相似文献

Comment on “Revealing Differences in Willingness to Pay Due to the Dimensionality of Stated Choice Designs: An Initial Assessment” 总被引:1,自引:1,他引:0

There are very few studies that quantify the interactions and tradeoffs between statistical and cognitive efficiency in designing
stated-choice studies. While a conceptual framework for evaluating cognitive strategies would be desirable, Hensher adopts
a strictly empirical approach in this experiment. The success of the study must be evaluated in light of his aggregating attributes
rather than controlling the number of attributes, asymmetry in the narrow-range and wide-range attributes, and lack of orthogonality
between the number of attributes and number of alternatives. Nevertheless, Hensher challenges uncritical acceptance of any
given set of design features and correctly insists that we confirm our experience with rigorous, quantitative experiments. 相似文献
