1.	Does School Quality Matter and for Whom? Evidence from Quantile Regression Analysis Presented: Cleveland, OH, Midwest Economics Association Annual Meeting, March 2001 Cohort(s): NLSY79 Publisher: Midwest Economics Association Keyword(s): Current Population Survey (CPS) / CPS-Fertility Supplement; Geocoded Data; Male Sample; Methods/Methodology; School Characteristics/Rating/Safety; School Quality; Schooling; Teachers/Faculty; Wage Determination; Wage Levels Permission to reprint the abstract has not been received from the publisher. This paper employs the quantile regression approach to estimate the wage effects of school quality. Using data from the Geocoded version of the NLSY79, the author has found consistent results with various samples and specifications that teacher degree and salary exert significantly larger effects at higher quantiles of the wage distribution, while the teacher-student ratio seems to favor individuals at lower quantiles. The author addresses the necessity to examine the effects of school quality on the whole wage distribution, rather than on the means, alone. Furthermore, the author argues that a correct question to ask is for whom school quality matters.

Evidence from a Quantile Regression Analysis. This essay uses quantile regressions to evaluate the diverse returns to school quality accruing to people who are at different positions in the wage distribution. Using data from the geocoded version of the NLSY79, We find that teachers with advanced degrees and better paid teachers have significantly larger benefits for individuals at higher quantiles of the wage distribution, while a high teacher/student ratio favors individuals at lower quantiles. These results are consistent across a variety of samples and specifications. While adopting different measures of student outcomes, this work reaches a conclusion that is similar to research in education - the estimated effect of school quality are misleadingly small when the average effect is considered. We argue that a correct question to ask is for whom school quality matters. Answering this question will help promote sound policies for targeting limited resources to be used most efficiently among heterogeneous students. Parental Expectations and Child Learning Performance. This essay estimates how parents affect their children's achievement by transmitting their preferences to their children. The model developed in the paper demonstrates that children whose parents have higher expectations for their achievement, spend more time studying conditional on their ability and previous achievement, and thus learn more. Using data from the NLSY79 Child & Young Adult, we construct a variable measuring parental expectations for children's educational attainment. These data are then linked to the summary tape files of 1990 Census and the Common Core of Data to obtain a unique data set on the characteristics of the neighborhoods and school districts where the NLSY children live. After controlling for a comprehensive set of characteristics of the children's mother, family, neighborhood, and school, we find a positive and significant effect of parental expectations on child learning performance.
