Backwards-induction Outcome in a Quantum Game
In economics duopoly is a market dominated by two firms large enough to influence the market price. Stackelberg presented a dynamic form of duopoly that is also called ‘leader-follower’ model. We give a quantum perspective on Stackelberg duopoly that gives a backwards-induction outcome same as the Nash equilibrium in static form of duopoly also known as Cournot’s duopoly. We find two qubit quan...
متن کاملBackwards induction in the centipede game
Imagine the following game, which is commonly called a ‘centipede game’. There is a pile of pound coins on the table. X and Y take it in turns to take either one or two coins from the pile, and they keep the coins they take. However, as soon as either of them takes two coins, the game stops, and the rest of the coins are cleared away. So long as they each take only one coin when their turn come...

متن کاملVirtual Implementation in Backwards Induction
We examine a sequential mechanism which is a simple modification of the normal form mechanism introduced by Abreu and Matsushima (1992). We show that almost any social choice function can be virtually implemented via a finite sequential game of perfect information. The solution concept assumed is backwards induction. In particular, any social choice function that is virtually implementable via ...
متن کاملBackwards Forward Induction
In this paper we isolate a particular refinement of the notion of Nash equilibrium that is characterized by (i) the fact that it provides a unified framework for both backwards and forward induction; and (ii) by the fact that it is mechanically computable. We provide an effective procedure, whose definition embodies certain given principles of rationality. Such a procedure allows us, given a re...
