In this essay, we argue that there is no scientific basis for the assumption that own well-being or command over resources is the exclusive and immutable concern of human individuals. The natural sciences, evolutionary biology in particular, and other social and behavioral sciences, especially...

We introduce opportunities for pre-play communication and to enter binding or non-binding contracts in trust games, and find (a) communication increases trusting and trustworthiness, (b) contracts are unnecessary for trusting and trustworthy behaviors and are eschewed by many players, (c) more...

We let subjects interact with anonymous partners in trust (investment) games with and without one of two kinds of pre-play communication: numerical (tabular) only, and verbal and numerical. We find that either kind of pre-play communication increases trusting, trustworthiness, or both, in...

An active area of research within the social sciences concerns the underlying motivation for sharing scarce resources and engaging in other pro-social actions. We develop a theoretical framework that sheds light on the developmental origins of social preferences by providing mechanisms through...

We explore the role of an individual's historical lineage in determining economic status, holding constant his or her current location. This is complementary to the more common approach to studying how history shapes economic outcomes across locations. Motivated by a large literature in social...

Effective states provide public goods by taxing their citizens and imposing penalties for non-compliance. However, accountable government requires that enough citizens are civically engaged. We study the voluntary cooperative underpinnings of the accountable state by conducting a two-level...

What became the post-War era’s “less developed countries” (LDCs) varied enormously in their pre- modern or pre-industrial economic conditions. We hypothesize that if these countries are arrayed on a continuum of pre-industrial development such as that of the demographer Ester Boserup,...

We conduct a laboratory experiment to study how demand for redistribution of income depends on self-interest, insurance motives, and social concerns relating to inequality and efficiency. Our choice environments feature large groups of subjects and real world framing, and differ with respect to...

We study experimentally the protection of property in five widely distinct countries - Austria, Mexico, Mongolia, South Korea and the United States. Our main results are that the security of property varies with experimental institutions, and that our subject pools exhibit significantly...

Previous research has shown that opportunities for two-sided partner choice in finitely repeated social dilemma games can promote cooperation through a combination of sorting and opportunistic signaling, with late period defections by selfish players causing an end-game decline. How such...
