The first measure, X(eff), is derivedassuming a constant risk aversion while the second measure, R(eff),is based...

This paper studies the statistical properties of the price, volatility and tick dynamics of the intraday Eurofutures markets by utilizing the transactions and quote data. We build two different types of price series, by position and by contract. The findings indicate numerous sources of intraday...

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...

The method of reconstructing an n-dimensional system from observations is to form vectors of m consecutive observations, which for m 2n, is generically an embedding. This is Takens's result. The Jacobian methods for Lyapunov exponents utilize a function of m variables to model the data, and the...

This paper introduces an entropy approach to measuring market expectations with respect to overnight interest rates in an inter-bank money market. The findings for the Turkish 2000-2001 borrowing crisis suggest that a dynamic, non-extensive entropy framework provides a valuable insight into the...
