Data Envelopment Analysis with Reverse Inputs and Outputs

Data envelopment analysis (DEA) assumes that inputs and outputs are measured on scales in which larger numerical values correspond to greater consumption of inputs and greater production of outputs. We present a class of DEA problems in which one or more of the inputs or outputs are naturally measured on scales in which higher numerical values represent lower input consumption or lower output production. We refer to such quantities as reverse inputs and reverse outputs. We propose to incorporate reverse inputs and outputs into a DEA model by returning to the basic principles that lead to the DEA model formulation. We compare our method to reverse scoring, the most commonly used approach, and demonstrate the relative advantages of our proposed technique. We use this concept to analyze all 30 Major League Baseball (MLB) organizations during the 1999 regular season to determine their on-field and front office relative efficiencies. Our on-field DEA model employs one output and two symmetrically defined inputs, one to measure offense and one to measure defense. The defensive measure is such that larger values correspond to worse defensive performance, rather than better, and hence is a reverse input. The front office model uses one input. Its outputs, one of which is a reverse output, are the inputs to the on-field model. We discuss the organizational implications of our results.     

Assessing the Impact of FCC Lifeline and Link-Up Programs on Telephone Penetration

Lifeline programs sponsored by the Federal Communications Commission (FCC) in cooperation with the states and Local Exchange Companies (LECs) are authorized to increase telephone penetration. Estimates of a variant of Perl's (1983) economic model with 1990 Census Data broken to the state level indicate that expenditures on these programs have a positive statistical effect on telephone penetration in most models. However, program elasticities are extremely small, suggesting that very large expenditure increases per poor household would have little effect on telephone penetration. Importantly, there is no relationship between the size of the state program elasticity and the level of state income or the magnitude of state poverty. We also demonstrate that the 1990 Census Data is superior to the Current Population Survey as a data base.

10 years experience of the german council of economic experts

Ten years ago, in August 1963, the Federal Republic of Germany set up a Council of Experts on Economic Development. The author — a former member of the Council — makes a resumé of the ten years’ experience and the problems connected with the Council.
