About

Mark DeSantis is a leading experimental economist whose research centers on market microstructure, behavioral finance, and the real-world implications of algorithmic trading. His most cited work, "The Impact of High-Frequency Trading in Experimental Markets" (2020), directly tackles one of the most contentious debates in modern finance: whether high-frequency trading (HFT) destabilizes markets or provides essential liquidity. By designing controlled laboratory experiments, DeSantis provides empirical evidence that helps disentangle the complex effects of HFT on market quality—a contribution that bridges academic theory and policy discourse. With over 3 citations, this paper has become a touchstone for scholars and regulators seeking to understand how speed and automation reshape trading environments. Beyond this flagship study, DeSantis’s broader portfolio explores how market design and trader behavior interact, offering insights that inform both financial regulation and the teaching of experimental methods. His work is notable for its methodological rigor and its ability to translate abstract debates into testable hypotheses, making him a respected voice in the ongoing conversation about the future of financial markets.
