Equilibrium Fast Trading
AbstractHigh-speed market connections and information processing improve financial institutions'ability to seize trading opportunities, which raises gains from trade. They also enable fast traders to process information before slow traders, which generates adverse selection. We first analyze trading equilibria for a given level of investment in fast-trading technology and then endogenize this level. Investments can be strategic substitutes or complements. In the latter case, investment waves can arise, where institutions invest in fast-trading technologies just to keep up with the others. When some traders become fast, it increases adverse selection costs for all, i.e., it generates negative externalities. Therefore equilibrium investment can exceed its welfare-maximizing counterpart
