Measuring Social Mobility As Unpredictability
By associating mobility with the unpredictability of social states, new measures of social mobility may be constructed. We propose a family of three state-by-state and aggregate (scalar) predictability measures. The first set of measures is based on the transition matrix. The second uses a sampling approach and permits statistical testing of the hypothesis of perfect mobility, providing a new justification for the use of the chi-squared statistic. The third satisfies the demanding criterion of "period consistency." An empirical example demonstrates the usefulness of the new measures to complement existing ones in the literature.
