Prof. Nisan Langberg serves as the Vice Dean at the Coller School of Management, Tel Aviv University, and concurrently leads The Harel Institute for Actuarial Innovation. A prominent scholar in finance and accounting, his research investigates corporate investment decisions, voluntary disclosure practices, and the economic implications of information asymmetry. His work has been published in leading journals including the Journal of Financial Intermediation, Journal of Accounting Research, Journal of Accounting and Economics, and Management Science.
Langberg's academic training includes a Ph.D. in Finance from Northwestern University's Kellogg School of Management (2004), where his dissertation on "Entrepreneurial Financing" was supervised by Michael Fishman. He also holds an M.A. in Economics from the joint program of Haifa University and the Technion Institute of Technology (1999), an M.A. in Statistics from Haifa University (1998), and a B.A. in Economics and Statistics from Haifa University (1997).
His research portfolio is anchored in Corporate Finance, with significant contributions to understanding optimal financing structures for growth-oriented firms, the dynamics of corporate fraud, and investment distortions in capital markets. In Financial Accounting, he has explored voluntary disclosure mechanisms, earnings management practices, and the relationship between audit quality and investment efficiency. His work in Information Economics examines how information production by analysts and informed traders shapes market efficiency and corporate decision-making.
Analysis of Langberg's publication history reveals a trajectory from foundational work on entrepreneurial financing and venture capital toward contemporary issues such as crowdfunding, real earnings management across firms, and strategic disclosure in IPO markets. A consistent theme throughout his career is the examination of how information asymmetry influences corporate investment policies and disclosure strategies, with implications for market regulation and corporate governance.
As the head of The Harel Institute for Actuarial Innovation, Langberg directs research initiatives that merge traditional actuarial science with cutting-edge technological innovations to address complex risk management challenges in financial markets and insurance industries.
