This paper proposes a structural time-series model for the intraday price dynamics on fragmented financial markets. We generalize the structural model of Hasbrouck (1993) to a multivariate setting. We discuss identification issues and propose a new measure for the contribution of each market to price discovery related to the Hasbrouck (1995) information shares. We apply the model to two sets of Nasdaq dealer quotes.
