Jonathan Morduch
Jonathan Morduch is Professor of Public Policy and Economics at New York University’s Wagner Graduate School of Public Service. Jonathan focuses on innovations that expand the frontiers of finance and how financial markets shape economic growth and inequality. Jonathan has lived and worked in Asia, but his newest book, The Financial Diaries: How American Families Cope in a World of Uncertainty (written with Rachel Schneider and published by Princeton University Press, 2017), follows families in California, Mississippi, Ohio, Kentucky, and New York as they cope with economic ups and downs over a year. The new work jumps off from ideas in Portfolios of the Poor: How the World’s Poor Live on $2 a Day (Princeton University Press, 2009), which Jonathan coauthored and which describes how families in Bangladesh, India, and South Africa devise ways to make it through a year living on $2 a day or less. Jonathan’s research on financial markets is collected in The Economics of Micro-finance and Banking the World, both published by MIT Press. At NYU, Jonathan is executive director of the Financial Access Initiative, a center that supports research on extending access to finance in low-income communities. Jonathan’s ideas have also shaped policy through work with the United Nations, World Bank, and other international organizations. In 2009, the Free University of Brussels awarded Jonathan an honorary doctorate to recognize his work on micro-finance. He holds a BA from Brown and a PhD from Harvard, both in Economics.
