Tying contracts are well-known for their anti-competitive potential. This paper questions their negative image by showing that tying contracts can be necessary to implement price signals which overcome problems of asymmetric information in the introductory phase of a new durable product. The...

We use the approach of the reduced Game Property and its converse to characterize the sets of stable and semistable demand vectors. It is shown that although these two concepts are generally very different their axiomatizations are almost the same. Regarding the semistable demand vector we...

This paper deals with a privatized firm facing potential market entry. The firm has inherited excess capacity from its public past. The players have asymmetric costs. Only the entrant must install new capacity, which incurs positive capacity installation costs. The paper considers the subgame...

The core of a linear assignment problem contains in general a continuum of allocations. A model is presented where the core shrinks to a unique solution as the population grows.

The relationship between risk and asset price fluctuations is studied in a stochastic overlapping generations asset pricing model with i.i.d. production shocks. The non-separability of preferences is an important factor in explaining the time paths of asset prices and returns. We show that the...

In the present paper we discuss the notion of values for games with coalition structure, applying the approach suggested by Hart and Mas-Colell (1985) concerning the consistency property and the potential function. An axiomatic formulation of the values by this approach leads to two known values...
