Yiming Ma

Yiming Ma is the Regina Pitaro Associate 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 a B.A. in Economics & Mathematical and Global Affairs from Yale University in 2013. 

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. Her findings have been published in leading academic journals, including the Review of Financial Studies and the Journal of Financial Economics, and cited by the Financial Times, the International Monetary Fund, the Securities and Exchange Commission, and the Federal Reserve.
