October 1999Economic Conditions, Deterrence and Juvenile Crime: Evidence from Micro Data
with H. Naci Mocan: w7405
This is the first paper to test the economic model of crime for juveniles using micro data. It uses a nationally representative sample of 16,478 high school children surveyed in 1995. The sample includes not only detailed information on offenses, but also data on personal, family and neighborhood characteristics as well as deterrence measures. We analyze the determinants of selling drugs, committing assault, robbery, burglary and theft, separately for males and females. We find that an increase in violent crime arrests reduces the probability of selling drugs and assaulting someone for males, and reduces the probability of selling drugs and stealing for females. An increase in local unemployment increases the propensity to commit crimes, as does local poverty. Similarly, family povert...
September 1991School District Leave Policies, Teacher Absenteeism, and Student Achievement
with Ronald G. Ehrenberg, Randy A. Ehrenberg, Eric L. Ehrenberg: w2874
In an effort to reduce salary costs, many school districts have begun to offer teachers financial incentives to retire early. Often, however, these districts have limits on the number of cumulated unused sick leave days that teachers may receive cash payments, credits toward future health insurance, or retirement credits for, at retirement. Thus, one might expect that in addition to stimulating early retirement, early retirement incentive programs may interact with sick leave provisions and provide an unintended incentive for increased teacher absenteeism. To the extent that less learning occurs when regular teachers are absent and student motivation to attend school is also reduced, student academic performance may suffer. This surely would be an unintended side effect of these policies. ...
June 1991How Would Universities Respond to Increased Federal Support for Graduate Students?
with Ronald G. Ehrenberg, Dominic J. Brewer: w3741
Projections of forthcoming shortages of Ph.D.s and thus new faculty for the academic sector, abound. Among the policies proposed to prevent such shortages is increased federal support for graduate students. Lost in the policy debate, however, has been concern for the possibility that increased federal support might induce academic institutions to redirect their own internal resources in a way that at least partially frustrates the intent of the policy change. Our paper presents an analysis of this issue using institutionally-based data for science and engineering fields. We find that doctorate-producing universities do respond to changes in external support for graduate students by altering the number of students they support on institutional funds. While adjustments to changes in external...
January 1990Faculty Turnover at American Colleges and Universities: Analysis of AAUP Data
with Ronald G. Ehrenberg, Hirschel Kasper: w3239
This paper uses institutional level data collected by the American Association of University Professors as part of their annual survey of faculty members' compensation to analyze faculty turnover. Analyses of aggregate data over almost a twenty-year period highlight how remarkably stable faculty retention rates have been nationwide and how little they vary across broad categories of institutions. Analyses of variations in faculty retention rates across individual institutions stress the role that faculty compensation levels play. Higher levels of compensation appear to increase retention rates for assistant and associate professors (but not for full professors) and the magnitude of this effect grows larger as one moves from institutions with graduate programs, to four-year undergraduate in...
