We extend the double-well potential process to a three-parameter version in order to model intraday price dynamics, with a focus on the intraday momentum and reversal. The proposed process has a parsimonious form of three parameters controlling momentum, reversal, and volatility respectively. By...

We introduce a Nelson-Siegel type interest rate term structure model with the underlying yield factors following … struc- ture and are associated with the time-varying uncertainty of the yield curve's level, slope and curvature. Estimating … the model based on U.S. government bond yields applying Markov chain Monte Carlo techniques we find that the yield factors …
