Abstract:
Among climate scientists, there is no longer any serious debate about whether greenhouse gas emissions from human activity are altering the earth' s climate. There is also a broad consensus on two issues related to reducing emissions. First, developing countries must be full participants in global emissions control, because they will be most heavily impacted by global warming, and because they are rapidly approaching parity with developed countries in the scale of their emissions. Second, efficient emissions control will require carbon pricing via market-based instruments (charges or cap-and-trade). These points of consensus are sufficient to establish a clear way forward, despite continued disagreements over the choice of specific instrument and the appropriate carbon charge level. Since all market-based systems that regulate emissions sources require the same emissions information, the international community should immediately establish an institution mandated to collect, verify and publicly disclose information about emissions from all significant global carbon sources. Its mandate should extend to best-practice estimation and disclosure of emissions sources in countries that initially refuse to participate. This institution will serve four purposes. First, it will lay the necessary foundation for implementing any market-based system of emissions source regulation. Second, it will provide an excellent credibility test, since a country's acceptance of full disclosure will signal its true willingness to participate in globally-efficient emissions reduction. Third, global public disclosure will itself reduce carbon emissions, by focusing stakeholder pressure on major emitters and providing reputational reward s for clean producers. Fourth, disclosure will make it very hard to cheat once market-based instruments are implemented. This will be essential for preserving the credibility of an international agreement to reduce emissions.

52. A Policymakers' Guide to Dutch Disease

Abstract:
It is sometimes claimed that an increase in aid might cause Dutch Disease—that is, an appreciation of the real exchange rate which can slow the growth of a country's exports— and that aid increases might thereby harm a country's long-term growth prospects. This essay argues that it is unlikely that a long-term, sustained and predictable increase in aid would, through the impact on the real exchange rate, do more harm than good, for three reasons. First, there is not necessarily an adverse impact on exports from Dutch Disease, and any impact on economic growth may be small. Second, aid spent in part on improving the supply side—investments in infrastructure, education, government institutions and health—result in productivity benefits for the whole economy, which can offset any loss of competitiveness from the Dutch Disease effect. Third, the welfare of a nation's citizens depends on their consumption and investment, not just output. Even on pessimistic assumptions, the additional consumption and investment which the aid finances is larger than any likely adverse impact on output. However, the macroeconomic effects of aid can cause substantial harm if the aid is not sustained until its benefits are realized. The costs of a temporary loss of competitiveness might well exceed the benefits of the short-term increase in aid. To avoid doing harm, aid should be sustained and predictable, and used in part to promote economic growth. This maximizes the chances that the long-term productivity and growth benefits will offset the adverse effects—which may be small if they exist at all—that big aid surges may pose as a result of Dutch Disease.
