We analyze the effect of price caps on equilibrium production and welfare in oligopoly under demand uncertainty. We find that high price caps always increase production and welfare as compared to the situation without price cap. Price caps close to marginal cost may lead to zero production,...

We study the importance of uncertainty and public finance to the welfare ranking of three environmental policy instruments: pollution taxes, pollution permits and Kyoto-like numerical rules for emissions. The setup is the basic stochastic neoclassical growth model augmented with the assumptions...

We demonstrate the advantages of a climate treaty based solely on rules for international permit markets when there is uncertainty about abatement costs and environmental damages. Such a ‘Rules Treaty’ comprises a scaling factor and a refunding rule. Each signatory can freely choose the...

The paper revisits the impact of uncertainty on the decision problem of a bank. The bank extends risky loans to private investors and sells deposits to savers at fixed rates. The uncertainty under which deposit/loan-portfolios are chosen by banks is endogenized through an information system that...

We study the importance of uncertainty and public finance to the welfare ranking of three environmental policy instruments: pollution taxes, pollution permits and Kyoto-like numerical rules for emissions. The setup is the basic stochastic neoclassical growth model augmented with the assumptions...

We welfare rank different types of second-best environmental policy. The focus is on the roles of uncertainty and public finance. The setup is the basic stochastic neoclassical growth model augmented with the assumptions that pollution occurs as a by-product of output produced and environmental...

Unintended consequences manifest themselves in many aspects of socioeconomic life. We develop a model of unintended consequences (UC) of novel policies. In our setup, the policymaker is unaware of the UC of her policy. We discuss several approaches to evaluating policy in terms of welfare...

A robust finding in experimental economics is that decision-makers often exhibit a much smaller dollar willingness to pay (WTP) for an item than the minimum amount that they claim to be willing to accept (WTA) to part with it. The spread between these two numbers is particularly large for public...
