We justify the application to extensive games of the concept of ‘fully permissible sets’, which corresponds to choice sets when there is common certain belief of the event that each player prefer one strategy to another if and only if the former weakly dominates the latter on the set of all...

A belief operator derived from preferences is presented. It generalizes ‘belief with probability1’ to incomplete preferences and satisfies minimal requirements for belief operators under weak conditions.

When uncertain evidence may lead to legal errors, a reduced standard of proof affects the incentive to violate the law. With noisy evidence, an agent may be convicted even if he obeys the law (type I error) or acquitted even if he violates the law (type II error). If the standard of proof is...

In many developing and transition economies Mafia-like activities are rampant. Extortion and other forms of predation lower profitability in private businesses and distort investment incentives. Incorporated in a model of industrialization, bimodal club convergence may result. Economies may get...

n an infinite horizon optimal control problem, the Hamiltonian vanishes at the infinite horizon, when the differential equation is autonomous. The integrand in the integral criterion may contain the time explicitly, but it has to satisfy certain integrability conditions. A generalization of...

In most models of transboundary pollution, lack of international cooperation does not cause any inefficiency within each country. The paper shows that this result is only valid in the hypothetical case of no international trade. With international trade, we get a domestic inefficiency in...

We consider the Hartwick rule for capital accumulation and resource depletion, provide semantic clarifications and investigate whether this rule indicates sustainability and requires substitutability between manmade and natural capital. In addition to shedding light on the meaning of the...

We discuss the prevalence of pooling equilibria in a two-period model of an insurance market with asymmetric information. We solve the model numerically. In addition to reporting cases where a pooling equilibrium exists, we pay attention to why, in the case of non-existence of a pooling...

We analyze infinite-horizon choice functions within the setting of a simple linear technology. Time consistency and efficiency are characterized by stationary consumption and inheritance functions, as well as a transversality condition. In addition, we consider the equity axioms Suppes-Sen,...

In the negotiations towards an agreement to reduce greenhouse gas emissions, one of the issues negotiated will be the allocation of emissions (or tradable emission permits) between countries. In most analyses and policy discussions, it is usually taken for granted that each country would like...
