The paper criticizes current conceptual frameworks focused on the evaluation of the performance of electoral systems. It offers a new tool allowing researchers to measure the size of the deviation of electoral outcomes from theoretical expectations. The index d = log[NS/(MS)1/6] is built on the Seat Product Model (Taagepera 2007b) and captures the deviations of electoral outcomes from predictions solely on the basis of two institutional factors – average district magnitude (M) and size of assembly (S). The theoretical background of index d is explained, and its reliability is further supported by conventional econometric methods based on empirical data.
