We study the macroeconomic effects of systemic bank runs in a neoclassical model with a microfounded banking system. In every period, the banks provide insurance against some idiosyncratic liquidity shocks, but the possibility of sunspot-driven bank runs distorts the equilibrium allocation. In a...

We develop in this paper simple geometrical methods to study local indeterminacy, bifurcations and stochastic (sunspot) equilibria near a steady state, in nonlinear two dimensional economic models. We present stochastic sunspot equilibria, which allows a constructive description of local...

It is well known from the literature that the introduction of financial constraints in economies with infinite-lived agents can be responsible for the occurrence of multiple equilibria and en- dogenous fluctuations. However, the question of the persistence of such phenomena when the constraints...

In the framework of consumer theory ala Lancaster, in which preferences are defined over bundles of characteristics embodied in goods rather than over goods themselves, a concept of "irrelevant" product differentiation is introduced and its relevance at equilibrium is analyzed. It is also argued...

In a game with positive externalities, such as e.g. the standard environmental externality game used in the analysis of international environmental agreements, the solutions having the property of coalitional internal stability, when they exist, are compared in this paper with the solutions with...

Effective supply chain management relies on information integration and implementation of best practice techniques across the chain. Supply chains are examples of complex multi-stage systems with temporal and causal interrelations, operating multi-input and multi-output production and services...

International negotiations have failed to achieve an ambitious outcome to limit climate risks. A Cournot outcome where countries determine their mitigation commitments in the full knowledge of those by others could be an important step. It would avoid a Stackelberg (leader-follower) outcome...

The plea bargaining procedure, namely the viability of a stage of bargaining between prosecutor and defendant in criminal suits, is analyzed in the framework of a two-sided incomlete information game.

The authors investigates refinements of two solutions, the saddle and the weak saddle, defined by Shapley (1964) for two-player zero-sum games. Applied to weak tournaments, the firsy refinement, the mixed saddle, is unique and gives us a new solution, generally lying between the GETCHA and...

A profit maximising auctioneer can provide a public good to a group of agents. Each group member has a private value for the good being provided to the group. We investigate an auction mechanism where the auctioneer provides the good to the group, only if the sum of their bids exceeds a reserve...
