  In this study we show how errors due to finite box size affect formation and
destruction rate for haloes in cosmological N-body simulations. In an earlier
study we gave an analytic prescription of finding the corrections in the mass
function. Following the same approach, in this paper we give analytical
expressions for corrections in the formation rate, destruction rate and the
rate of change in comoving number density, and compute their expected values
for the power law ($n=-2$) and LCDM models.
