Second, we find that assimilation similarly extends to coverage of employment-based anti-smoking policies such as worksite smoking bans and smoking cessation programs while enclave residence does not substantially influence these outcomes. Third, we document complex relationships between assi...
August 2009Do Expenditures Other Than Instructional Expenditures Affect Graduation and Persistence Rates in American Higher Education
with Douglas A. Webber, Ronald G. Ehrenberg: w15216
During the last two decades, median instructional spending per full-time equivalent (FTE) student at American 4-year colleges and universities has grown at a slower rate than median spending per FTE student in a number of other expenditure categories including academic support, student services and research. Our paper uses institutional level panel data and a variety of econometric approaches, including unconditional quantile regression methods, to analyze whether these non instructional expenditure categories influence graduation and first-year persistence rates of undergraduate students. Our most important finding is that student service expenditures influence graduation and persistence rates and their marginal effects are higher for students at institutions with lower entrance test s...
