Exploratory behaviors can serve an adaptive role within novel or changing environments.
Namely, they facilitate information gain, allowing an organism to maintain accurate beliefs …

All adaptive organisms face the fundamental tradeoff between pursuing a known reward
(exploitation) and sampling lesser-known options in search of something better …

Previous research in economics shows that compensation based on the pay-for-
performance principle is effective in inducing higher levels of effort and productivity. On the …

We test the core ideas of the “automata” approach to bounded rationality, using simple
experimental bandit tasks. Optimality requires subjects to use a moderately complex …

Cultural evolution is driven, in part, by the strategies that individuals employ to acquire
behavior from others. These strategies themselves are partly products of natural selection …

The bandit problem is a dynamic decision-making task that is simply described, well-suited
to controlled laboratory study, and representative of a broad class of real-world problems. In …

I study discrimination arising from individual experiences of employers with worker groups. I
present a model in which employers are uncertain about the productivity of one of two …

Humans and animals learn from experience by reducing the probability of sampling
alternatives with poor past outcomes. Using simulations, JG March (1996) illustrated how …

We develop a model of customer choice in response to random variation in quality. The
choice model yields closed-form expressions which reflect the effect of competing suppliers' …

How humans achieve long-term goals in an uncertain environment, via repeated trials and
noisy observations, is an important problem in cognitive science. We investigate this …
