Data envelopment analysis was introduced as a nonparametric linear programming estimator to estimate the production frontier and technical efficiency of observed production units. Allowing multiple inputs and multiple outputs, the approach can be considered a nonparametric quantile regression...

Recent analyses of baseball managers' performances have employed the so-called 'Pythagorean Theorem' of baseball. This 'theorem' states that the ratio of wins to losses can be approximated by the square of the ratio of team runs scored to opposition runs scored. Recent publications assume this...

Nationwide, most public school teachers are paid according to a uniform salary schedule determined by their school or district. While this precludes variation in salaries over teachers of identical qualifications within a school, there is variation across schools in the parameters of the salary...

In this paper we develop a Malmquist productivity index for public sector production characterized by the influence of environmental variables. We extend Johnson and Ruggiero (2011) to the more general case of variable returns to scale to further decompose the Malmquist productivity index into...
