This paper constructs a type space that contains all types with a finite depth of reasoning, as well as all types with an infinite depth of reasoning - in particular those types for whom finite-depth types are conceivable, or think that finite-depth types are conceivable in the mind of other...

Rationalizability is a central concept in game theory. Since there may be many rationalizable strategies, applications commonly use refinements to obtain sharp predictions. In an important paper, Weinstein and Yildiz (2007) show that no refinement is robust to perturbations of high-order...

"Social interaction is essential to human life. How do people choose what to do when they encounter one another? And how do organizations, firms or countries interact? Game Theory is a modeling tool designed to represent and analyze such strategic interaction. The first part of this book is...
