This paper explores the impact of memory in standard display imitation behavior, focusing on coordination games (as in Kandori et al (1993)) and N-player games where spiteful behavior allows to discard Nash equilibria. It is shown that the way interea is modeled in such examples actually entails...

Article VI of the GATT allows counter measures of goods are sold on a foreign market at a price below average production plus transportation costs. The present article analyzes Article VI based on a simple game theoretic model with two countries and economies of scale in the production of one...

The traditional model of sequential decision making, for instance, in extensive form games, is a tree. Most texts define a tree as a connected directed graph without loops and a distingueshed node, called the root. But an abstract graph is not a domain for decision theory. Decision theory...

We consider economies with incomplete markets, one good per state, two periods, t=0,1, private ownership of initial endowments, a single firm, and no assets other than shares in this firm. In Dierker, Dierker, Grodal (2002), we give an example of such an economy in which all market equilibria...
