Finding a universal market impact formula remains one of the most fascinating puzzles in finance. This paper reviews two possible approaches for imposing restrictions on this formula. First, restrictions can be obtained from a system of economic equations using trading volume and volatility, as suggested by Kyle and Obizhaeva (2017b). Second, restrictions can be derived using dimensional analysis and leverage neutrality, as suggested by Kyle and Obizhaeva (2017a). Except for the knife-edged case of the square root market impact function, additional assumptions related to market microstructure invariance are needed to apply the same market impact formula to all assets simultaneously. This results in a tightly parameterized universal market impact formula suitable for empirical testing.

Albert S. (Pete) Kyle has been the Charles E. Smith Chair Professor of Finance at the University of Maryland’s Robert H. Smith School of Business since 2006. He earned is B.S. degree in mathematics from Davidson College (summa cum laude, 1974), studied philosophy and economics at Oxford University as a Rhodes Scholar from Texas (Merton College, 1974-1976, and Nuffiled College, 1976-1977), and completed his Ph.D. in economics at the University of Chicago in 1981. He has been a professor at Princeton University (1981-1987), the University of California Berkeley (1987-1992), and Duke University (1992-2006).
Kyle’s research focuses on market microstructure, including topics such as high frequency trading, informed speculative trading, market manipulation, price volatility, the informational content of market prices, market liquidity, and contagion.
His teaching interests include market microstructure, institutional asset management, venture capital and private equity, corporate finance, option pricing, and asset pricing.
He is a Fellow of the American Finance Association in (2013) and a Fellow of the Econometric Society (2002) . He has been a board member of the American Finance Association (2004-2006). He holds an honorary doctoral degree from the Stockholm School of Economics (2013). He was a staff member of the Presidential Task Force on Market Mechanisms (Brady Commission, 1987), a consultant to the SEC (Office of Inspector General), CFTC, and U.S. Department of Justice, a member of NASDAQ’s economic advisory board (2004-2007), a member of the FINRA economic advisory board (2010-2014), and a member of the CFTC’s Technology Advisory Committee (2010-2012).
About the Series
The IAQF's Thalesians Seminar Series is a joint effort on the part of the IAQF (www.iaqf.org) and the Thalesians (www.thalesians.com). The goal of the series is to provide a forum for the exchange of new ideas and results related to the field of quantitative finance. This goal is accomplished by hosting seminars where leading practitioners and academics present new work, and following the seminars with a reception to facilitate further interaction and discussion.
