The rate of information diffusion and, consequently, price discovery are conditional not only upon the design of the market microstructure but also the informational structure. This paper presents a market microstructure model showing that an increasing number of information hierarchies among...

This paper introduces a new nonparametric test to identify jump arrival times in high frequency financial time series data. The asymptotic distribution of the test is derived. We demonstrate that the test is robust for different specifications of price processes and the presence of the...

Volatility clustering, with autocorrelations of the hyperbolic decay rate, is unquestionably one of the most important stylized facts of financial time series. This paper presents a market microstructure model, that is able to generate volatility clustering with hyperbolic autocorrelations...
