I am an economist working in the World Bank Office of the Chief Economist for the Africa region. I study how risk and uncertainty shape economic decision making. Some current work looks at how religious institutions in developing countries act as insurers. I have approached many questions through a variety of lab, field, and lab-type field experiments in what some coauthors insist on calling “exotic places”. Please click here for my CV.
