-transaction duration process and vice versa. In order to solve the estimation problems implied by this interdependent formulation, we first … propose a GMM estimation procedure for the Autoregressive Conditional Duration model. The method is then extended to the … simultaneous estimation of the interdependent duration-volatility model. In an empirical application we utilize the model for an …

This paper introduces the Markov-Switching Multifractal Duration (MSMD) model by adapting the MSM stochastic volatility … model of Calvet and Fisher (2004) to the duration setting. Although the MSMD process is exponential ß-mixing as we show in …-memory duration models in an out-of-sample forecasting exercise based on price durations of three major foreign exchange futures …
