Abstract: In this paper, a locally stabilized finite element formulation of the Stokes problem is analyzed. A macroelement condition which is sufficient for the stability of (locally stabilized) mixed methods based on a piecewise constant pressure approximation is introduced. By satisfying this condition, the stability of the $ {Q_1} - {P_0}$ quadrilateral, and the $ {P_1} - {P_0}$ triangular element, can be established.
