RSM research on stock exchange competition wins paper award

Dr Sarah Draus from Rotterdam School of Management, Erasmus University (RSM) won this year’s FESE De la Vega Prize for her paper on the effects of multi-market trading on stock exchange fees. The assistant professor of finance received the award in Vienna in June 2018, at the annual convention of the Federation of European Securities Exchanges (FESE).



In her paper Market power on exchanges: linking price impact to trading fees, Dr Sarah Draus describes how recent regulations such as the European Directive MiFID, aimed at making trading and exchange services more competitive, triggered the proliferation of competing trading venues and resulted in high order flow fragmentation. Her theoretical paper demonstrates that fragmentation allows liquidity providers and exchanges to retain market power. The results are derived in the framework of a duopoly competition model, in which a rational trader fragments his order to reduce price impact whenever exchanges are not completely liquid. This behaviour induces mark-ups on both transaction prices and exchange trading fees.

Practical implications

Dr Draus’ study suggests that regulation that leads to new entrants in a monopolistic exchange industry, such as the European Directive MiFID, influences trading fees through two channels: first through the direct competition effect since trading volume can be split, and second through its effect on market liquidity, which also determines trading fees. Estimating empirically the importance of each channel is highly relevant for financial regulators and other policy makers.

Outstanding research

FESE awards its FESE De la Vega Prize annually for an outstanding research paper by academics or practitioners. The papers must be about current developments in European securities markets which promote public markets.

The jury consisted of academics and leaders from top business schools and financial institutions, including Warwick Business School, Goldman Sachs, the Eurasian Economic Commission, and Copenhagen Business School.

The 2018 prize was awarded by FESE President Deirdre Somers, CEO of Euronext Dublin, and Rainer Riess, FESE’s Director General, at the Gala Dinner of the FESE Convention in Vienna on 20 June 2018.
