There is a general agreement that (a) climate change is one of the most serious environmental problems, that (b) the analysis of climate change is confronted with a large degree of uncertainty and (c) that these uncertainties need to be taken into account to arrive at meaningful policy...

This paper develops a real options approach to the optimal sequencing of antiretroviral drug cocktails for HIV/AIDS patients in resource-poor settings. The analysis focuses on the implications of endogenous resistance mutations in the virus that reduce or eliminate the effectiveness of...

Degradation of ecosystem services may be a major component of climate change damage, and incorporation of this factor could significantly alter the significance of uncertainty in climate-economy modeling. However, this aspect has been little investigated by economic analyses of climate change...

This note presents an experimental study of the random lottery incentive mechanism. In the baseline treatment we observe risk behavior in a given choice problem. We show that by integrating a second, asymmetrically dominated choice problem in a random incentive mechanism risk behavior can be...

We apply standardized numerical techniques of stochastic optimization (Judd [1998]) to the climate change issue. The model captures the feature that the effects of uncertainty are different with different levels of agent's risk aversion. A major finding is that the effects of stochasticity...

Several models of choice under uncertainty imply systematic violations of transitivity of preference. Our experiments explored whether people show patterns of intransitivity predicted by these models. To distinguish “true” violations from those produced by “error,” a model was fit in...

Experiments on choice under risk typically involve multiple decisions by individual subjects. The choice of mechanism for selecting decision(s) for payoff is an essential design feature that is often driven by appeal to the isolation hypothesis or the independence axiom. We report two...

The impact of exchange rate uncertainty on international trade has been discussed controversially in economic policy and theory for a long time. The paper surveys the theoretical investigations on this topic. The early modeis which analyse the influence of exchange rate uncertainty on trade,...

There is a large literature showing that willingness-to-accept (WTA) is usually much higher than willingness-to-pay (WTP) in empirical studies although they should be roughly equal according to traditional economic theory. A second stream of literature shows that people are typically ambiguity...

Several experimental studies observed substantial violations of transitivity in decisions between risky lotteries over monetary outcomes. The goal of our experiment is to test whether these violations also affect the evaluation of health states. A particular feature of our experimental design is...
