Subgame perfect implementation: A new result

TL;DR

This paper explores how quantum mechanics can modify the traditional framework of subgame perfect implementation, proposing a quantum stage mechanism that extends to macro settings via an algorithmic approach.

Contribution

It introduces a quantum stage mechanism that amends the traditional subgame perfect implementation characterization, applicable also in macro environments through an algorithmic method.

Findings

Quantum stage mechanism modifies traditional implementation conditions.

Amendment applies in macro settings via an algorithmic stage mechanism.

Traditional characterization is extended with quantum considerations.

Abstract

This paper concerns what will happen if quantum mechanics is concerned in subgame perfect implementation. The main result is: When additional conditions are satisfied, the traditional characterization on subgame perfect implementation shall be amended by virtue of a quantum stage mechanism. Furthermore, by using an algorithmic stage mechanism, this amendment holds in the macro world too.
