We find all the mixed strategy equilibria, within a certain class, of the simplified three-firm location model of Hotelling (in which the price variable is ignored).

We study a model in which collusive duopolists divide up the monopoly profit according to their relative bargaining power. We are particularly interested in how the negotiated profit shares depend on the sizes of the firms. If each can produce at the same constant unit cost up to its capacity,...

Necessary and sufficient conditions are obtained for the existence of an equilibrium point (as well as for the existence of a dominating equilibrium point) in a two-person non-zero sum game of timing.
