Measuring mobility

Measuring Forager Mobility

Mobility plays a large role in generating the patterns of stone raw-material usage seen in forager archaeological sites, but how best to translate these patterns into a complete quantitative characterization of the organization of forager mobility remains a difficult problem. The number of potential variables involved, including raw-material quality and abundance as well as individual movement ...

Measuring Upward Mobility

This paper develops a mobility measure that combines desirable features of the relative and absolute approaches to measuring mobility. From the relative approach we borrow the idea that income growth accruing to the relatively poor is more to be valued than income growth to the relatively rich. From the absolute approach we take the idea that upward changes are to be valued, in and of themselve...

Measuring Career Mobility: An Empirical Comparison of Six Mobility Indexes

The current paper presents six indexes that can be used to characterize the course of a career during a particular time interval, respectively, (1) the total number of transitions during that interval; (2) the number of positive transitions; (3) the number of negative transitions; (4) the subtraction of the number of negative transitions from the number of positive transitions; (5) the relative...

Measuring Income Mobility over Equivalent Adults

The amount of flexibility in the ”earnings market” has attracted the interest of many researchers during the last two decades. Given a heterogeneous population, it has been shown that results strongly depends on equivalence scales and related initial definitions. In this paper we argue that in order to rank income distributions over income mobility there are strong theoretical and empirical rea...
