In this course

Dale Stahl is an experimental economist known for work on bounded rationality and cognitive hierarchy models—frameworks that model how players with different levels of strategic reasoning interact in games. His research, often co-authored with Wilson, provides empirical data on how actual human decision-makers deviate from perfect rationality assumptions, enabling the course readings to ground discussions of computational cognition and disequilibrium in experimental evidence rather than idealized theory. This work bridges economics and cognitive science, relevant to how the course examines machine learning as a model (or departure from) human strategic and adaptive behavior.

A Cognitive Hierarchy Theory of Games

Another possibility is to assume that k-step players realize there are other k-step thinkers (g<sub>k</sub>(k) > 0). Self-awareness of this sort is a step away from the goal of creating a precise disequilibrium theory, because it imposes co…A COGNITIVE HIERARCHY MODEL 879 TABLE IV MODEL FIT (LOG-LIKELIHOOD LL AND MEAN SQUARED DEVIATION MSD) | Data set | Stahl and Wilson | Cooper and Van Huyck | Costa-Gomes et al. | Mixed | Entry | | :--- | :---: | :---: | :---: | :---: | :--…The graphs enable us to answer an important question visually: when the Nash predictions are good approximations, is Poisson-CH almost as accurate? The answer appears to be yes, because there are few points with low Nash deviations and high…
