This paper examines the contribution of supervisors to an organization's output by constructing a production function in which supervisors' time and case workers' time enter as inputs. There is a quality variable associated with output: average delay. The functional form of the production...

A theoretical model which estimates the probability of injury to occupants of vehicles in two-car collisions is presented and evaluated. This model is based on considerations of principles from mechanics and observations from biomechanics. It is evaluated using two-car accident injury data. The...
