Poorer countries have a much smaller public sector and correspondingly a smaller tax burden than richer countries, yet, their economic performance has not been necessarily better. Using a simple model, this paper suggests that the growth and welfare effects of taxation are mediated through...

We study the. Incentive effects of endogenous group formation in a voluntary contributon experiment. Subjects are given information on the past contributions of others and allowed to express a preference for partners. On the basis of the stated preferences new groups are formed. We find that the...

When subjects can make non-binding announcements of possible contributions to a public good numerically, there is no effect on average level of contributions in a public goods experiment relative to play without announcements. But a detailed analysis of this experiment shows that pre-play...

In a public goods experiment with the opportunity to vote to expel members of a group, we found that contributions rose to nearly 100% of endowments with significantly higher efficiency compared with a noexpulsion baseline. Expulsions were strictly of the lowest contributors, and there was an...

We compare two devices previously found to increase contributions to public goods in laboratory experiments: communication, and punishment (allowing subjects to engage in costly reductions of one another’s earnings after learning of their contribution decisions). We find that communication...

Mounting evidence suggests that the outcomes of laboratory public goods games, and collective action in firms, communities, and polities, reflect the presence in most groups of individuals having differing preferences and beliefs. We designed a public goods experiment with targeted punishment...

We explore the effects of mandatory third-party review of mortgage contracts on the terms, availability, and performance of mortgage credit. Our study is based on a legislative experiment in which the State of Illinois required 'high-risk' mortgage applicants acquiring or refinancing properties...

Using new household-level data, we quantitatively assess the roles that job loss, negative equity, and wealth (including unsecured debt, liquid assets, and illiquid assets) play in default decisions. In sharp contrast to prior studies that proxy for individual unemployment status using regional...

This document summarizes the thrust of my monograph book Disasters and the Networked Economy (2003, NY: Routledge. 228 pp. ISBN: 978-0-415-66629-9). It is no substitution for the book, but it attempts to make salient the main concepts, explanations and conclusions of it. It does so by first...
