Measuring Movement of Incomes
Economica, 66 (264): 455-455 (1999)
Zusammenfassung
We consider a small set of elementary properties for income movement
measures, and show that there is essentially only one measure that
satisfies all of these properties: the per capita aggregate change
in log-incomes. We demonstrate next that this movement-mobility
measure has a number of appealing descriptive and normative properties,
and provide a formal generalization of our basic characterization
theorem drawing from the related literature on poverty measurement.
Finally, we present here an empirical application in which we show
by using our new measure that there has been a broad-based increase
in income movement in the United States between the 1970s and 1980s.
