A quantum-statistics theory is derived for the processes which occur in small Josephson junctions at low temperatures. When the current, the temperature, and the quasiparticle admittance are all below certain limits, the dynamics of the system is similar to that of a quantum-mechanical particle in a one-dimensional periodic potential. The possible occurrence of ''Bloch oscillations'' in the junction is analyzed on the basis of an adiabatic Hamiltonian. The current-voltage characteristic of the system is derived. The factors most important in suppressing or masking the Bloch oscillations are discussed. The possibility of observing these effects experimentally is analyzed.
