摘要
In the paper, using L,vy processes subordinated by 'asymptotically self-similar activity time' processes with long-range dependence, we set up new asset pricing models. Using the different construction for gamma (I") based 'asymptotically self-similar activity time' processes with long-range dependence from Finlay and Seneta (2006) we extend the constructions for inverse-gamma and gamma based 'asymptotically selfsimilar activity time' processes with integer-valued parameters and long-range dependence in Heyde and Leonenko (2005) and Finlay and Seneta (2006) to noninteger-valued parameters.
