This paper investigates how the passage of time affects trust, trustworthiness, and cooperation. We use a hybrid lab and online experiment to provide the first evidence for the persistent power of communication. Even when 3 weeks pass between messages and actual choices, communication raises...

Using a large-scale hybrid laboratory and online trust experiment with and without pre-play communication, we investigate how the passage of time affects trust, trustworthiness, and cooperation. Communication (predominantly through promises) raises cooperation, trust, and trustworthiness by...

We study whether employment history can provide information about a worker's noncognitive skills - in particular about "work attitude", or the ability to work well and cooperatively with others. Our hypothesis is that, holding all else equal, a worker's frequent job changes can indicate poorer...

We study how the willingness to enter long-term bilateral relationships affects cooperation even when parties have little information about each other, ex ante, and cooperation is otherwise unenforceable. We experimentally investigate a finitely-repeated Prisoner's Dilemma, allowing players to...

We study the stability of voluntary cooperation in response to varying rates at which a group grows. Using a laboratory public-good game with voluntary contributions and economies of scale, we construct a situation in which expanding a group’s size yields potential efficiency gains, but only...

We study whether employment history can provide information about a worker's non-cognitive skills - in particular, about "work attitude", or the ability to work well and cooperatively with others. We conjecture that, holding all else equal, a worker's frequent job changes can indicate poorer...

We propose that heterogeneous asset trading behavior is the result of two distinct, non-convertible mental dimensions: analytical ("quantitative") capability and mentalizing ("perspective-taking") capability. We develop a framework of mental capabilities that yields testable predictions about...
