## Biography

Breza received her BA in Economics and Mathematics from Yale University in 2005, followed by her PhD in economics from the Massachusetts Institute of Technology in 2012. At MIT, she was a student of Abhijit Banerjee and Esther Duflo, co-winners of the 2019 Nobel Memorial Prize in Economic Sciences. After completing her graduate degree, Breza joined the faculty of Columbia Business School, before moving to Harvard University in 2017.
In addition to her academic appointment, Breza is co-chair of the Finance Initiative of the Abdul Latif Jameel Poverty Action Lab, and a Foreign Editor for The Review of Economic Studies. She is also an affiliated researcher at the National Bureau of Economic Research, International Growth Centre, Bureau for Research and Economic Analysis of Development, and Centre for Economic Policy Research. In 2020, she was the recipient of a Sloan Research Fellowship, awarded annually by the Alfred P. Sloan Foundation to support early-career scientists and scholars.
In 2019, Breza was a signatory to an open letter expressing concern over political interference in official statistics in India.

## Research

Breza's primary research interests concern labor and financial markets in developing countries, and the impact of social networks on information delivery.

### Financial markets and technologies

In an article with Martin Kanz and Leora Klapper, Breza leverages a randomized experiment in Bangladesh to show that factory workers who receive wages in digital bank or mobile money accounts learn to use the new technology, improving trust in banking, savings, and responsiveness to adverse economic shocks.
In work with Cynthia Kinnan, Breza studies the Indian microfinance crisis of 2010, in which the state of Andhra Pradesh suddenly halted all microfinance activities, reducing the gross loan portfolio of lenders by 20% in just one year. She shows that the sudden shutdown decreased rural wages, in contrast to other evidence suggesting a limited role for microfinance in improving incomes.
In a paper with Arun Chandrasekhar in Econometrica, Breza leverages a randomized controlled trial in 30 Indian villages to show that assigning community monitors to track savings behavior of households increases their effective savings rates by 36%.

### COVID-19 pandemic

During the COVID-19 pandemic, Breza co-authored several papers examining the impacts of information delivery on social distancing and other preventative health behaviors. In a paper in Nature Medicine, Breza and co-authors show that Facebook advertising campaigns encouraging staying at home during the 2020 Thanksgiving and Christmas holidays reduced average distance traveled and subsequent COVID-19 infections.
In related work, she shows that the impact of physician messaging on demand for information on COVID-19 and willingness to pay for masks does not vary systematically between white and black Americans. Breza's research on COVID-19 was supported by a National Science Foundation Grant for Rapid Response Research, on which Abhijit Banerjee, Esther Duflo, Benjamin Olken, and Marcella Alsan were co-principal investigators.
