This survey discusses behavioral and experimental macroeconomics emphasizing a complex systems perspective. The economy consists of boundedly rational heterogeneous agents who do not fully understand their complex environment and use simple decision heuristics. Central to our survey is the...

We design an experiment to test the hypothesis that, in violation of Bayes Rule, some people respond more forcefully to the strength of information than to its weight. We provide incentives to motivate effort, use naturally occurring information, and control for risk attitude. We find that the...

We examine by means of an artefactual field experiment on a representative sample of Italian adults, the impact of information and belief elicitation on charitable-giving when donors know (or express their beliefs on) what the organizations received in terms of aggregate donations in the past....

One of the challenges in managing the Earth’s common pool resources, such as a livable climate or the supply of safe drinking water, is to motivate successive generations to make the costly effort not to deplete them out of reasons including inter-generational beneficence. In the context of...

We report on experimental evidence rationalizing the use of heterogeneous agent models. We provide compelling evidence that subjects in laboratory experiments often behave in ways that depart from the rational choice ideal. Further, these subjects' heuristic approaches often differ from one...

This study considers prospects for the revitalization of social norms after ethnic conflict in the case of post-war Bosnia-Herzegovina. Between September 2003 and January 2004, a total of 681 subjects took part in a survey and a series of behavioral decision-making experiments across Bosnia....

One constraint we face as economists is not being able to observe all the relevant variables required to test our theories or make policy prescriptions. Laboratory techniques allow us to convert many variables (such as beliefs) that are unobservable in the field into observables. This paper...
