With Wendy Carlin and the CORE team I am producing open access materials to transform both the content and the pedagogy of the introductory economics course, including an e-text, as well as a conventional text.
Daniele Girardi, Mattia Fochesato and I use "institution shocks" to study how changes in institutions affect wealth inequality and other aspects of the economy.
Monique Borgerhoff Mulder and I head a large team of anthropologists and economists contributing to SFI's Dynamics of Wealth Inequality project.
Two current programs of the Dynamics of Wealth Inequality Project incorporating both theoretical and empirical studies concern polygyny and wealth inequality (The Polygyny Puzzle Project, with Monique and Cody Ross and Seung-Yun Oh) and network structure and wealth inequality (with Monique, Matt Jackson, Eleanor Power, Simon DeDeo, Jeremy Koster and Paul Hooper).
With Jung-Kyoo Choi, Suresh Naidu and Sung-Ha Hwang I use stochastic evolutionary game theory and other methods (including archaeological and historical evidence) to better understand institutional and technological innovation, and the persistence of institutions and social norms as well as transitions among institutional, cultural, linguistic and other conventions.
Sung-Ha Hwang and I are working on approaches to mechanism design and public policy that take account of altruism, reciprocity and other social preferences.
