The preemptive role of capital is analysed in a class of two-player symmetric capital accumulation differential games with reversible investment. It is proved that, in the medium run, the firm with better initial condition exploits its advantage when the game features feedback substituability....

This paper provides sufficient conditions for the existence of pure strategy Nash equilibrium in a class of games of group formation. The use of potential allows for a characterisation of such an equilibrium.

This paper studies a population of agents, each of whom can be either an Altruist or an Egoist. Altruists confer benefits on others at a cost to themselves. Altruism is thus a strictly dominated strategy and cannot survive if agents are rational best-responders. We assume that agents choose...

We show that a strategy profile of a normal form game is proper if and only if it is quasi-perfect in every extensive form (with that normal form). Thus, properness requires optimality along a sequence of supporting trembles, while sequentiality only requires optimality in the limit.

If an inspector is work averse and his effort spent on investigating reports is not observable this creates a moral hazard problem whenever there is an imperfect monitoring technology. This problem arises because the organization can not distinguish between an inspection that doesn't find...

Tax compliance is modelled as a Bayesian Nash equilibrium in a costly state verification game with imperfect auditing. Neither the tax payer nor the auditor can measure the tax payer's true liability precisely: they observe independent noisy signals.

The paper considers an extension of the original Shapley and Shubik (1972) two-sided matching problem to the case of multisided matching with transfereable utility. We investigate existence and properties of stable matchings using the approach of cooperative game theory.

The paper provides a general analysis of the types of models with E-Perturbations which have been used recently to discuss the evolution of social conventions. Two new measures of the size and structure of the basins of attraction of dynamic systems, the radius and coradius, are introduced in...
