Abstract:In experiments, people do not always appear to think very strategically or to infer the information of others from their choices. We report experimental results in games of private information with three information states, which vary in strategic complexity. "Mousetracking" is used to record which game payoffs subjects look at, for how long, to learn more about the thinking process. Subjects often deviate from Nash equilibrium choices, converge only modestly toward equilibrium across 40 trials, and often fail… Show more
“…The Level-k model has also been applied successfully to a variety of other games, including "hide-and-seek" games [27], incomplete-information betting games [11], betting games and matrix games [57], coordinated attack games [48], sender-receiver games augmented with eye-tracking data [65], and cheap-talk games [45]. In the field, Level-k has been shown to fit behavior in Swedish lowest-unique-positive-integer lottery games [55] and to explain the fact that movies that were not released to critics before their public opening earn higher revenues [12].…”

“…The capacity bounds the level, so k i (γ, τ i ) ≤ c i (γ) for all i, γ, and τ i . 11 Let Θ be the space of all possible types. Note that c i does not vary in τ i since the capacity represents a player's underlying ability to "solve" a particular game, regardless of the type of her opponent.…”

ABSTRACT. We examine whether the "Level-k" model of strategic behavior generates reliable cross-game predictions at the individual level. We find no correlation in subjects' estimated levels of reasoning across two families of games. Furthermore, estimating a higher level for Ann than Bob in one family of games does not predict their ranking in the other. Direct tests of strategic reasoning generally do not predict estimated levels. Within families of games, we find that levels are fairly consistent within one family, but not the other. Our results suggest that the use of Level-k reasoning varies by game, making prediction difficult.

“…CH models predict that level-0 and level-1 thinkers won't understand how this information can guide a player. This leads to interesting phenomena that are not possible in equilibrium analysis, such as dishonest sellers exploiting gullible buyers [31 ,32]; the 'winner's curse,' where bidders can only guess the value of an object (e.g., oil lease auctions), perhaps too optimistically [28,33]; and zero-sum speculation in which two people should never agree to bet each other, but often do [34,35].…”
