Application of Difference-in-Difference Techniques to the Evaluation of Drought-Tainted Water Conservation Programs.
Bamezai, Anil
Evaluation Review, v19 n5 p559-82 Oct 1995

These include differential response to the drought, self-selection bias, and measurement error. How to deal with these problems when high-quality disaggregate data are available is discussed. (SLD)
