The concepts of sequential and quasi-perfect rationalizability are defined in an epistemic model by means of lexicographic probabilities. These are non-equilibrium analogs to sequential and quasi-perfect equilibrium, for which epistemic characterizations are provided. The defined...

This paper presents an economic model of prostitution, which differs from the existing literature in that it makes no restrictive assumptions regarding the gender, pay, and nature of forgone earning opportunities of prostitutes and clients, and applies the same behavioural hypotheses to both....

This paper reports on recurring laboratory elections in which buyers and sellers choose institutional rules to govern a subsequent trading round. The bid auction (buyers propose prices), offer auction (sellers suggest prices) and double auction (both trader types initiate price quotes) make up...

We study the role of technology subsidies in climate policies, using a simple dynamic equilibrium model with learning-by-doing. The optimal subsidy rate of a carbon-free technology is high when the technology is first adopted, but falls significantly over the next decades. However, the...

This paper addresses the impact of endogenous technology through research and development (R&D) and learning by doing (LbD) on the timing of environmental policy. We develop two models, the first with technological change through R&D and the second with LbD. We study the interaction between...

In this paper, we view health insurance as a combined hedge against the two consequences of falling ill: treatment expenditures and loss in income. We discuss how an individual’s ability when healthy affects her decision on whether to buy health insurance with treatment to full recovery if ill...

We consider an economy where most of the health care is publicly provided, and where there is waiting time for several types of treatments. Private health care without waiting time is an option for the patients in the public health queue. We show the effects of a tax (positive or negative) on...

We explore the efficacy of price and quantity controls as environmental policy instruments in a stochastic setting in which agents are risk averse. We demonstrate that the assumption of risk aversion may improve the performance of a tax relative to that of a system of tradable quotas, and that...
