Granny versus Game Theorist: Ambiguity in Experimental Games

Granny versus game theorist: ambiguity in experimental games

We report on an experiment in which subjects choose actions in strategic games with either strategic complements or substitutes against a granny, a game theorist or other subjects. The games are selected in order to test predictions on the comparative statics of equilibrium with respect to changes in strategic ambiguity. We find that subjects face higher ambiguity while playing against the gran...

Ambiguity Aversion in Game Theory: Experimental Evidence

This paper studies games with ambiguity averse agents, focusing on the relationship between preferences, beliefs over opponent’s preferences, and behaviour in normal form games. Using a carefully chosen 3×2 normal form game we find that a subject’s risk and ambiguity preferences affect the subject’s behaviour in normal form games in the direction suggested by economic theories. In contrast, we ...

Game Theory Explorer - Software for the Applied Game Theorist

This paper presents the “Game Theory Explorer” software tool to create and analyze games as models of strategic interaction. A game in extensive or strategic form is created and nicely displayed with a graphical user interface in a web browser. State-of-the-art algorithms then compute all Nash equilibria of the game after a mouseclick. In tutorial fashion, we present how the program is used, an...

Game-XP: Action Games as Experimental Paradigms for Cognitive Science

Why games? How could anyone consider action games an experimental paradigm for Cognitive Science? In 1973, as one of three strategies he proposed for advancing Cognitive Science, Allen Newell exhorted us to "accept a single complex task and do all of it." More specifically, he told us that rather than taking an "experimental psychology as usual approach," we should "focus on a series of experim...
