Abstract

This Paper proposes a structural time series model for the intra-day price dynamics of 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. We illustrate the model by an empirical example using Nasdaq dealer quotes.
