Improving the Use of Empirical Research as a Policy Tool: An Application to Education.
Summers, Anita A.; Wolfe, Barbara L.
In this paper, the replication process is explored in an attempt to answer the question of which school resources help the learning of junior high school age students. In order to test a theory derived from data on 553 eighth grade students from 42 Philadelphia schools, three forms of replication are used, examining: (1) a larger, much less disaggregated data set, (2) a randomly selected stored sample, and (3) a modification of the larger sample, using a missing variable technique to develop estimators for the unsatisfactorily aggregated data. It is found throughout the replications that schools are not impotent; specifically, (1) organizational and teacher characteristics affect learning growth and (2) the negative effects of race and income can be traced through their impact on the absorption of particular school outputs. It is concluded that education production coefficients can contribute more to the policy reviews associated with budget cutbacks and declining enrollment if efforts are made to improve their reliability by using pupil specific, longitudinal data and by replicating. Furthermore, it is held that encouragement should be given to developing large readily available data bases which are disaggregated, longitudinal, and have wide geographical coverage. (Author/GC)
