Alternative Measures of the Explanatory Power of General Multivariate Regression Models

In this paper R 2-type measures of the explanatory power of multivariate linear and categorical probit models proposed in the literature are reviewed and their deficiencies discussed. It is argued that a measure of the explanatory power should take into account the components which are explicitly modelled when a regression model is estimated while it should be indifferent to components not explicitly ...

Incentives for Basic Research in a Large Institution: Some General Considerations and a Case Study

Discusses incentives for basic research, which were recently introduced in the German Institute for Economic Research, including both team and individual incentives. Possible problems arise from focussing on the measurable, crowding out intrinsic motivation and undesirable externalities. Furthermore, provides survey evidence on the perception of the incentives by the institute's researchers.

Implementing the Kyoto Protocol without Russia

This paper examines implementation of the Kyoto Protocol without Russia. It concludes that implementation without Russia is possible, although it requires political will on the part of the countries that wish to proceed with the Protocol. It would lead to higher compliance costs for Annex B buyer regions, but other regions, except Russia, would benefit financially. Russia would forego revenue of at ...

In the Aftermath of Dresden: New Directions in German Flood Insurance

The German flood disaster of summer 2002 highlighted a dilemma concerning insurance against damages caused by natural forces. On the one hand, mindful of the rising incidence of natural disasters, private insurance companies are increasingly withdrawing coverage against natural catastrophes such as wind storms and floods. On the other, the availability of emergency relief and private donations is systematically ...

Terrorism and International Trade: An Empirical Investigation

This paper examines the effect of terrorism and warfare on international trade. We investigate bilateral trade flows between more than 200 countries over the period from 1960 to 1993. Applying an augmented gravity model that includes several measures of terrorism and large-scale violence, we find compelling evidence that terrorist actions reduce the volume of trade; a doubling in the number of terrorist ...

Vertical Foreclosure versus Downstream Competition with Capital Precommitment

The recent literature on vertical foreclosure suggests that vertical integration can have the anticompetitive effect of enabling an upstream firm to commit to restricting output to downstream firms at the monopoly level. We allow the upstream firm to make an ex-ante capital precommitment. We show that, if integration is outlawed, the upstream firm will distort capital downward as an alternative device ...

Games of Climate Change with International Trade

We analyse games of greenhouse gas emission reduction in which the emissions and the emission reduction costs of one country depend on other countries' emission abatement. In an analytically tractable model, we show that international trade effects on costs and emissions can either increase or decrease incentives to reduce emissions and to cooperate on emission abatement; in some specifications, optimal ...
