This grant provides three years of continued operational support to the Household Finance Working Group (HFWG) at the National Bureau of Economic Research. The group brings together leading economists, econometricians, regulators, and policymakers working on issues broadly related to understanding how households make economic decisions. Specific topics addressed by the working group include household saving, portfolio behavior, borrowing decisions, investment choices, risk management, and bankruptcy.К Over the next three years, the HFWG will continue its work with a focus on how changes in technology are affecting both household decision-making and the opportunities to study it. Topics to be examined include the rise of fintech, big data, and machine learning in the provision of consumer financial services; the impact of electronic payment systems, such as cryptocurrencies, on traditional financial institutions; and both the challenges as well as the opportunities posed by the use of administrative data for research on consumers and their financial decisions.
