Knowledge that Transforms

We analyze gender wage gaps correcting for sample selection induced by nonemployment. We recover wages for the nonemployed using alternative imputation techniques, simply requiring assumptions on the position of imputed wages with respect to the median. We obtain higher median wage gaps on imputed rather than actual wage distributions for several OECD countries. However, this difference is small in the United States, the United Kingdom, and most central and northern EU countries and becomes sizable in southern EU countries, where gender employment gaps are high. Selection correction explains nearly half of the observed negative correlation between wage and employment gaps. (c) 2008 by The University of Chicago Press. All rights reserved.

We examine how well principals can distinguish between more and less effective teachers. To put principal evaluations in context, we compare them with the traditional determinants of teacher compensation—education and experience—as well as value‐added measures of teacher effectiveness based on student achievement gains. We present “out‐of‐sample” predictions that mitigate concerns that the teacher quality and student achievement measures are determined simultaneously. We find that principals can generally identify teachers who produce the largest and smallest standardized achievement gains but have far less ability to distinguish between teachers in the middle of this distribution.

Editor's Note Our policy is to annotate all English-language books on economics and related subjects that are sent to us. A very small number of foreign-language books are called to our attention and annotated by our consulting editors or others. Our staff does not monitor and order books published; therefore, if an annotation of a book does not appear six months after the publication date, please write to us or the publisher concerning the book. An Index of Authors of New Books appearing in the Annotated Listings will appear at the end of the General Index in the December issue.
