We investigate the effect of collisional broadening by using a quasiparticle spectral function recently proposed by Spicka and Lypavsky. Calculations are performed within a Monte Carlo procedure and applied to a simple semiconductor model to obtain average values and correlation functions. Problems concerning the stationarity of the system and the long energy tail of the spectral function are discussed.
