Sequencing and the Adding-up Property in Contingent Valuation of Endangered Species: Are Contingent Non-Use Values Economic Values?

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.     

Global emissions effects of CDM projects with relative baselines

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.     

Organizational types and leadership roles

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.     

Indirect Taxes on International Aviation*

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.     

An Evaluation of the Vanderbilt-JCEE Experimental PSI Course in Elementary Economics

This is considerably longer than articles normally accepted by the JEE, but we considered it to be an important follow-up of our Special Issue No. 2, “The Vanderbilt-JCEE Experimental Course in Elementary Economics.” (Winter 1974.) The authors address a number of aspects of PSI, some of which have rarely been touched upon by other researchers interested in this method. This paper deals not only with student learning and student reactions to PSI, but with its effects on performance in higher level economics courses, its impact on the student proctors in terms of their learning of economics, and the costs of establishing and maintaining a PSI course. Siegfried and Strand have not answered all the questions pertaining to self-paced instruction but, along with Allison, Billings, Fels, Soper, Spector, Tietenberg and others, they have contributed significantly to our knowledge of the effectiveness of PSI.     

Fiscal implications of climate change

Climate change is an externality problem—so the challenges that arise in limiting it and dealing with the effects that remain are largely fiscal. The structure of the problem, however, and the uncertainty which surrounds it, make the design of proper policy responses particularly complex. This paper provides a primer on the fiscal implications of climate change, the aim being to provide a (reasonably) quick and comprehensive overview of the main analytical issues and lessons learned.     

Measuring voting power in an international institution: the United States and the inter-American development bank

This paper applies a measure of relative voting power to the weighted voting system of the Inter-American Development Bank (IADB). Almost all assessments of internal governance of the IADB and other international financial institutions make reference to members' votes as a proxy for relative influence. But as this paper demonstrates, voting weights are misleading. The number of votes a country has in a weighted voting system does not necessarily denote its ability to affect outcomes. The conventional wisdom holds that the United States is omnipotent in the IADB because it has a large number (over 30 percent) of all the votes. This paper reveals that the U.S. obtains much more control over outcomes than originally intended by the institutions' designers. Received: September 2000 / Accepted: October 2001
