This paper studies models where the optimal response functions under consideration are non-increasing in endogenous variables, and weakly increasing in exogenous parameters. Such models include games with strategic substitutes, and include cases where additionally, some variables may be...

Internet growth has allowed unprecedented widespread access to cultural creation including music and films, to knowledge, and to a wide range of consumer information. At the same time, it has become a huge source of business opportunities. Along with great benefits that this access to the...

Bergstrom, Blume and Varian (1986) provides an elegant game-theoretic model of an economy with one private good and one public good. Strategies of players consist of voluntary contributions of the private good to public good production. Without relying on first order conditions, the authors...

The aim of this paper is to introduce prospect theory in a game theoretic framework. We address the complexity of the weighting function by restricting the object of our analysis to a 2-player 2-strategy game, in order to derive some core results. We find that dominant and indifferent strategies...

The theory of games (or game theory) is a mathematical theory that deals with the general features of competitive situations. It involves strategic thinking, and studies the way people interact while making economic policies, contesting elections and other such decisions. There are various types...

This chapter presents a summary of recent results obtained in game and social choice theories, and highlights the application and the development of tools in algebraic topology. The purpose is expository: no attempt is made to provide complete proofs, for which references are given, nor to...

The article deals with problem of forming of Pareto non-optimal norms of mutual behavior of investors and government in the process of decision-making related to financing of reduction of risks of investment activity in economy. The game-theoretical analysis suggests that inefficiency of arising...

Democracy resolves conflicts in difficult games like Prisoners’ Dilemma and Chicken by stabilizing their cooperative outcomes. It does so by transforming these games into games in which voters are presented with a choice between a cooperative outcome and a Pareto-inferior noncooperative...

I show how improper conditioning of beliefs can lead to under-contribution in public goods environments with interdependent values. I consider a simple model of a binary, excludable public good. In equilibrium, provision of the public good is good news about its value. Naive players who...
