This paper studies models where the correspondences (or functions) under consideration are never increasing (or weakly decreasing) in endogenous variables, and weakly increasing in exogenous parameters. Such models include games of strategic substitutes, and include cases where additionally,...

If each member of a group assigns a certain probability to a hypothesis, what probability should the collective as a whole assign? More generally, how should individual probability functions be merged into a single collective one? I investigate this question in case that the individual...

This paper develops a utility model for evaluating lotteries. In estimating utility, risk averse people use an asymmetric loss function. Expected utility is seen as a special case that is a good approximation in some cases. The model resolves several paradoxes and makes easily falsifiable...

Current analysis addresses an apparently critical issue of wealth circulation in the society. We try to play a game with the welfare- related burden of taxation. Thus, the Negotiator No.1 stands up for citizens legal and moral rights to social services. The Negotiator No.2 proceeds from the...

If bigger objects go into a jar, then there will be space to fill it with smaller objects in sequence. If the order of the objects are reversed, then it ends in filling it at the starting point. Happiness in life is similar to this. Fill high priority needs in the life, and smaller needs can be...

Current analysis addresses an apparently critical issue of wealth circulation in the society. In the form of three persons game, we put the welfare-related burden on taxpayers. The Negotiator No.1 stands up for citizens’ legal and moral right to social services. The Negotiator No.2 proceeds...
