In this paper, we propose a new econometric approach to jointly model the time series dynamics of the trading process and the revisions of ask and bid prices. We use this model to test the validity of certain symmetry assumptions very common among microstructure models. Namely, we test whether ask and bid quotes respond symmetrically to trade-related shocks, and whether buyer-initiated trades and seller-initiated trades are equally informative. In essence, the procedure we propose generalizes Hasbrouck s (1991) vector autoregressive model for signed trades and changes in the quote midpoint by...

Das Buch behandelt Erweiterungen okonometrischer Modelle mit qualitativen erklarenden Variablen auf simultane Gleichungssysteme. Die vorgestellten Schatzverfahren, kurz als simultane Probit- und Tobitmodelle bezeichnet, bieten die Moglichkeit, strukturelle simultane Zusammenhange zwischen diskreten sowie gestutzten Variablen, wie sie haufig in Individualdatensatzen zu beobachten sind, zu schatzen. Im ersten Teil werden verschiedene neuere Verfahren zur Schatzung der Strukturparameter in simultanen Probit- und Tobitmodellen vorgestellt und auf ihre asymptotischen Eigenschaften untersucht....
