Yiming Ma is an assistant professor in the finance division at Columbia Business School. She received her Ph.D. in Finance from the Stanford Graduate School of Business in 2018 and holds a BA from Yale University.
Her research focuses on financial intermediation, financial stability, and monetary policy. She is particularly interested in the evolving landscape of financial intermediation, where non-banks like mutual funds and ETFs are increasingly engaged in liquidity transformation while the traditional banking sector is transforming less liquidity than before. Her recent work examines the implications of this trend on asset prices, financial stability, and monetary policy transmission.
