Summary: | This paper validates a recently proposed
method to estimate intra-generational mobility through
repeated cross-sectional surveys. The technique allows the
creation of a "synthetic panel" -- done by
predicting future or past household income using a set of
simple modeling and error structure assumptions -- and thus
permits the estimation of lower and upper bounds on
directional mobility measures. The authors validate the
approach in three different settings where good panel data
also exist (Chile, Nicaragua, and Peru). In doing so, they
also carry out a number of refinements to the validation
procedure. The results are broadly encouraging: the
methodology performs well in all three settings, especially
in cases where richer model specifications can be estimated.
The technique does equally well in predicting short and
long-term mobility patterns and is robust to a broad set of
additional "stress" and sensitivity tests.
Overall, the paper lends support to the application of this
approach to settings where panel data are absent. |
