In panel surveys, some observation units drop out before the end of the observation period. This panel attrition cannot be ignored if it is related to the variables of interest. Hirano, Imbens, Ridder and Rubin (Econometrica, 2001) propose the …

This thesis deals with attrition in panel data. The problem associated with attrition is that it can lead to estimation results that suffer from selection bias. This can be avoided by using attrition models that are sufficiently unrestrictive to …
We report an empirical analysis of the responses of the supply and demand for secondary care to waiting list size and waiting times. Whereas previous empirical analyses have used data aggregated to area level, our analysis is novel in that it focuses …
