Abstract

Every finite extensive-form game with perfect information has a subgame-perfect equilibrium. In this note we settle to the negative an open problem regarding the existence of a subgame-perfect $$\varepsilon $$ ε -equilibrium in perfect information games with infinite horizon and Borel measurable payoffs, by providing a counter-example. We also consider a refinement called strong subgame-perfect $$\varepsilon $$ ε -equilibrium, and show by means of another counter-example, with a simpler structure than the previous one, that a game may have no strong subgame-perfect $$\varepsilon $$ ε -equilibrium for sufficiently small $$\varepsilon >0$$ ε > 0 , even though it admits a subgame-perfect $$\varepsilon $$ ε -equilibrium for every $$\varepsilon >0$$ ε > 0 .
