Economic anthropology is a contested area of interdisciplinary research. Although some practitioners define the task as the application of mainstream economic theorizing to the full range of human groups in time and space, many others argue in the light of the ethnographic evidence that it is...

This paper analyzes data from a novel field experiment designed to test the impact of twodifferent insurance products and a secret saving device on solidarity in risk-sharing groupsamong rural villagers in the Philippines. Risk is simulated by a lottery. Risk-sharing ispossible in solidarity...

We design a field experiment to study gender differences in misconduct, a significant yet poorly understood issue. We construct a census of the market for mobile banking in rural Ghanaian villages, and using actual transactional audits estimate that 1 out of every 5 mobile money transactions is...

We analyze whether the availability of formal insurance products affects informal solidarity transfers in two independent behavioral experiments in the Philippines. The first experiment allows for communication, non-anonymity and unrestricted transfers. The second experiment mimics a laboratory...

In this paper we use experimental data collected in rural Cameroon to quantify the effect of social distance on trust and altruism. Our measure of social distance is one that is relevant to everyday economic interactions: subjects in a Trust Game play with fellow villagers or with someone from a...

This document describes a whole-farm model based on data from farm scale crop, sheep and native pasture experiments managed by scientists. The data are integrated using linear programming (LP), and tests of the economic viability of intensified production systems are presented. A six year...

Most research in economics models agents somehow motivated by outcomes. Here, we model agents motivated by procedures instead, where procedures are defined independently of an outcome. To that end, we design procedures which yield the same expected outcomes or carry the same information on...

This paper investigates how group membership and competition among trustors interact with trust and trustworthiness in a laboratory one-shot trust game. To analyze these effects, we apply a 2x2 design. We induce group membership by letting subjects play coordination games with clear focal...

Psychological game theory can provide a rational choice explanation of framing effects; frames influence beliefs, and beliefs influence motivations. We explain this point theoretically, and explore its empirical relevance experimentally. In a 2×2-factorial framing design of one-shot public good...

This experimental study investigates how behavior changes after punishment for an unkind action. It also studies how fairness perceptions affect the reaction to punishment and whether this effect is consistent across repeated play and role experiences. A repeated version of the power-to-take...
