  Statistical properties of energy levels, wave functions and
quantum-mechanical matrix elements in disordered conductors are usually
calculated assuming diffusive electron dynamics. Mirlin has pointed out [Phys.
Rep. 326, 259 (2000)] that ballistic effects may, under certain circumstances,
dominate diffusive contributions. We study the influence of such ballistic
effects on the statistical properties of wave functions in quasi-one
dimensional disordered conductors. Our results support the view that ballistic
effects can be significant in these systems.
