Sumario: | We present an asset pricing model based on a randomly indexed branching process as proposed by T.W. Epps in 1996, as an alternative for the stochastic modeling of the price of assets in high frequency. The basic results of the theory that allows understanding the model, the characterization of the prices under a geometric distribution of two offspring parameters, and simulations of the price under different levels of intensity of the processes that determine the number of generations are considered. Extensions of the model are proposed in different directions. |
