We study the mass accretion histories (MAHs) and density profiles of dark matter halos using N-body simulations of self-similar gravitational clustering from scale-free power spectra, $P(k)\propto k^n$.

Our scaling reproduces the mass power spectra of the target cosmology to better than 0. 5% on large scales (k < 0. 1 h/Mpc) both in real and in redshift space.
