Although a direct relationship among partial withdrawals (Ws), GPA and grade inflation (GI) is suggested in prior research, this study demonstrates just the opposite. Evidence from a detailed panel-data comprising 39,337 sections offered in the UPR-Bayamón during 41 consecutive terms...

Adopting the geometric concepts of a tangent line and a secant ray allows for determining the curvature (convex, concave, or linear) and the behavior of the marginal and average tax rates of an income increasing tax function. Such information helps to determine whether the tax function is...

This study uses a rich longitudinal data-set of 13,202 full-time students belonging to 11 cohorts over 22 consecutive semesters (Fall 1995 to Spring 2006) to model the determinants of the grade inflation rates prevailing at the University of Puerto Rico at Bayamón. The following new interesting...

Over concerns about private school students' advantages in standardized tests, beginning in 1995-96 the University of Puerto Rico (UPR) implemented a new admissions formula that reduced the weight they previously had in the General Admissions Index (GAI), on which its admissions decisions are...

This paper explores new angles of the student evaluation of teaching (SET) debate. The SET ratings of 179 full-time professors of the University of Puerto Rico-Bayamón were tracked from 1998–1999 to 2003–2004. Information on the characteristics of professors, students, and courses was...

In making admission decisions, many colleges have de-emphasized standardized test scores. Using data for seven cohorts of applicants to the University of Puerto Rico, we assess the ability of test scores and other proxies of academic potential to predict student GPA. We study sample selection...

This paper explores new angles of the student evaluation of teaching (SET) debate. The SET ratings of 179 full-time professors of the University of Puerto Rico-Bayamón were tracked from 1998–1999 to 2003–2004. Information on the characteristics of professors, students, and courses was...

This paper synthetizes the discussion of the mathematical conditions required to calculate the Cobb-Douglas surface concavity and their implications with certain regularity conditions of the neoclassical model. The surface is strictly concave, concave, or strictly quasiconcave depending on the...
