Extensive cooperation among unrelated individuals is unique to humans, who often sacrifice
personal benefits for the common good and work together to achieve what they are unable …

Increasingly, algorithms are supplanting human decision-makers in pricing goods and
services. To analyze the possible consequences, we study experimentally the behavior of …

We study the complexity of rules by paying experimental subjects to implement a series of
algorithms and then eliciting their willingness-to-pay to avoid implementing them again in …

Women's reluctance to negotiate is often used to explain the gender wage gap, popularizing
the push for women to “lean in” and negotiate more. Examining an environment in which …

This paper compares behavior under four different implementations of infinitely repeated
