This paper analyzes the dynamics of prices around such events using simulation techniques and standard measures of market quality like the bid-ask spread. When the market-maker is a monopolistic pricesetter, experiments show that myopic profit-maximization, apart from leading to poor market quality, is sub-optimal even for the market-maker in the sequential context. This observation leads to an interesting characterization of the monopolistic market-maker's exploration-exploitation dilemma as a tradeoff between price discovery and profit-taking. When traders can place limit orders, the presence of market-makers leads to more effective price-discovery and greater price stability under a...
