Professor Michael Gallmeyer (Ph.D. University of Pennsylvania 1998): I am a specialist in continuous-time asset pricing where my main interest is the equilibrium effect of market imperfections on security prices and investor behavior. My work focuses on several types of market frictions including differential taxation across investors, heterogeneous beliefs about security returns, and incomplete markets. My current research centers around market manipulation induced by over the counter derivative positions as well as the valuation of stocks with uncertain growth opportunities when investors have diverse opinions about the stock's prospects.
