Pricing ratchet equity-indexed annuities with early surrender risk in a CIR++ mode / Xiao Wei, Marcellino Gaudenzi, Antonino Zanette
Sumario: In this article we propose a lattice algorithm for pricing simple Ratchet equity-indexed annuities (EIAs) with early surrender risk and global minimum contract value when the asset value depends on the CIR++ stochastic interest rates. In addition we present an asymptotic expansion technique that permits us to obtain a first-order approximation formula for the price of simple Ratchet EIAs without early surrender risk and without a global minimum contract value. Numerical comparisons show the reliability of the proposed methods
