This paper presents tests of the theoretical validity of the contingent valuation (CV) method. The validity of CV is especially a concern when involving environmental goods with a predominant non-use value. One test of theoretical validity is the adding-up property that implies that a specific good should be equally valued irrespectively of it is being valued directly or built-up sequentially. In this CV study four independent sub-samples stated willingness to pay for the same composite good, or package, using different sequences. One sub-sample valued the composite good directly, while two sub-samples faced built-up sequences valuing first subsets of this composite good. A fourth sub-sample valued the composite good from a dividing-out approach, facing first the valuation of a larger multi-package. Theoretically expected sequencing effects were observed; the subset goods obtained higher values earlier in a sequence, and the dividing-out approach decreased the stated value for the composite good. Most importantly, these CV data did pass the tests of the adding-up property.  相似文献

The Nordic healtheare model is recognized to be one of the most innovative in the world. Here billions of USD are annually invested in developing new treatments, drugs, robots etc. to diagnose and cure diseases. Nevertheless, this study establishes that there is a fundamental shortcoming in the system that supports healthcare innovation: It is strongly biased towards micro-level innovation projects focusing on new products, alternative processes, and new financial solutions. The problem with this approach to support new projects is that the results are created as inventions within the system thus lacking holistic perspectives. This has consequently contributed with increasing costs that are out of proportion with existing budgets. Therefore this study seeks to analyze the current understanding of the Nordic healthcare system from a business model perspective. Here other aspects of the healthcare system are explored to determine if they could be redesigned to promote new types of innovation projects. The purpose of undertaking this task is to challenge the established patterns of the current healthcare innovation support practices. Here the vertical innovation process (VIP) framework, which is a systematic radical innovation model that seeks macro-level outcomes based on standalone inventions (see more below), is applied to analyze the current state-of-the-art in Nordic healthcare innovation projects. The results determine that very little attention is given to rethink and redesign the healthcare system at a macro-level, and it is discussed that stand-alone inventions ought to be rethought into the entire healthcare system to create a larger impact. Finally, it is argued that existing performance measures are inappropriate to foster projects that innovate the existing system: New measuring points should be developed to promote macro-level projects and to avoid the current rapid increase of costs in the Nordic healthcare system.  相似文献

This paper discusses whether and to what extent resource-rich developing countries should introduce local content policies, i.e. requirements to include local inputs in petroleum extraction activities of multinational corporations. We argue that local content needs to be seen as a public expenditure question, since local content requirements increase multinational costs, and hence reduce the taxes which can be extracted from these companies. This implies that there are opportunity costs in imposing local content requirements, since the forgone taxes can be used in others ways which could potentially do more to improve development prospects. Moreover, past experiences of resource-rich developing countries suggest that local content policies can exacerbate key problems of patronage and rent-seeking which resource rents generate, increasing the chance that the resource wealth will prevent rather than help development. These arguments suggest that an optimal local content policy in the context of flawed institutions is a more limited one than those typically pursued by developing countries with recently discovered petroleum reserves. Using qualitative data from Tanzania, a country with recent discoveries of substantial natural gas deposits, we analyze why local content tends to become such a central issue in debates and policy processes, despite its potentially problematic aspects.  相似文献

The effect of within-group heterogeneity on the survival of social groups is theoretically ambiguous. A greater diversity of ideas, experience, and networks can have a positive effect on members’ benefits from group membership, but diversity also creates a potential for conflict. This paper analyzes the relation between heterogeneity and exit of microcredit groups, using data from Angola. The results suggest that the form of group heterogeneity matters. Fragmentation in terms of social identities, or more specifically religious-linguistic fractionalization, is associated with a greater probability of group exit. Within-group economic inequality, however, is associated with a decrease in the probability of exit, but at a diminishing rate.  相似文献

CDM is an offset mechanism designed to reduce the overall cost of implementing a given global target for greenhouse gas (GHG) emissions in Annex B countries of the Kyoto Protocol. A problem with CDM is that it provides incentives to increase, if possible, the baseline emissions for CDM projects, to optimize the value of CDM credits. Under a “relative baselines” crediting rule, the CDM may also unduly increase energy consumption even during the CDM implementation phase. Less than full offset of emissions is then likely, and the CDM will lead to increased global GHG emissions. We show that this is a potentially serious problem, due to asymmetric information between project hosts and the regulator, the CDM Executive Board, and to the basic rules for crediting CDM quotas. In certain cases, the use of “relative baselines” to credit CDM quotas could fully eliminate any emissions reductions achieved by CDM projects. Remedies to overcome the problems are discussed. They may involve setting the baseline independently of initial energy intensity and final output for the project; or involve information revelation mechanisms that minimize policy losses and net rent capture by project sponsors.  相似文献

A new round of trade negotiations through the World Trade Organization (WTO) was launched in 2001. One of the major aims of the Doha Development Round is to reduce agricultural protection and impose greater discipline on domestic agricultural subsidies, particularly those that are the most trade distorting. In this article, we examine whether the proposed WTO modalities for agriculture will actually achieve this aim in Norway, which ranks among the top providers of government assistance for agriculture. Norway has a complex system of farm subsidies buttressed by substantial import protection. The extent to which its agricultural support policies will have to change in response to new WTO disciplines provides an important indication of how successful these are likely to be. We find that Norway will probably be able to sustain its current agricultural activity and production levels while staying within the new WTO rules. Following recent practice in some other WTO members, Norway will be able to reduce its notified support without making real changes in some of its programmes. However, there will have to be a shift from market price support, which is paid for by consumers through higher food prices, to budgetary support paid by taxpayers. This could generate increased domestic pressure for policy reform.  相似文献

Certain managerial functions are necessary or of greater importance in certain organizations. The following relations between organization types and leadership roles are hypothesized: expert organizations and producers, bureaucratic organizations and administrators, group organizations and integrators, and task organizations and entrepreneurs. The analysis shows that striving for results and achieving goals (i.e. producer role) is a role requirement that appears in all types of organization, whereas integrating behavior was required as a secondary requirement, again in all four types of organization. It was also found that the union stewards overestimated their leaders’ efficacy as administrators and entrepreneurs, whereas the leaders themselves overestimated their own efficacy as producers and integrators. The leader’s length of service with the organization reduces the inclination towards the producer role, but is conducive to the role of administrator.  相似文献

There has recently been much discussion of the possible use of internationally coordinated indirect taxes, or equivalent charges, on international aviation, whether as a source of finance for development or as part of a response to heightened concerns with climate change. This paper considers the strengths and weaknesses of the leading candidate instruments of this kind. It argues that, on both policy and administration grounds, the case for increasing indirect taxes on international aviation is strong: the indirect tax burden on international aviation is very low, yet aviation contributes significantly to border-crossing environmental damage, is just as proper an object of taxation as any other commodity, and incipient tax competition is likely to result in these taxes being set at inefficiently low levels. But the form(s) in which such taxes are levied matters: a tax on aviation fuel would address the key border-crossing externalities most directly; a tax on final ticket values would have greater revenue potential, and perhaps some distributional advantage; departure/arrival taxes face the least legal obstacles, but are much blunter instruments. Optimal policy, it is shown, typically requires deploying both a fuel tax and a ticket tax, and the paper explores, both in principle and by simulation, the key considerations and trade-offs involved in designing a suitable indirect tax regime for international aviation.  相似文献
