A seller with two objects faces a group of bidders who are subject to budget constraints. The objects have common values to all bidders, but need not be identical and may be either complements or substitutes. In a simple complete information setting we show: (1) if the objects are sold by means...

We present a synthesis of various folk theorems for repeated games.

Perfect equilibria of finitely repeated games may be vulnerable to the possibility of renegotiation among players. The authors study the limiting properties of the set of payoffs from equilibria that are immune to renegotiation. Their main result is th at the limit of the set of payoffs from...

The authors study a dynamic model of duopoly in which firms choose both prices and quantities. If quantity (capacity) choices are relatively inflexible , firms generally carry excess (idle) capacity in equilibrium. Because of this enforcement cost, firms are unable to achieve monopoly levels....

We present a synthesis of the various folk theorems for repeated games using a model that accommodates both finitely and infinitely repeated games with discounting. We derive a central result for this model and show that the various folk theorems follow as a consequence. Our result encompasses...
