This paper proposes a self-contained reference for both policy makers and scholars who want to address the problem of efficiency and effectiveness of Local Public Transport (LPT) in a sound empirical way. Framing economic efficiency studies into a transport planning perspective, it offers a...

University rankings are the subject of a paradox: the more they are criticized by social scientists and experts on methodological grounds, the more they receive attention in policy making and the media. In this paper we attempt to give a contribution to the birth of a new generation of rankings,...

In efficiency analysis the assessment of the performance of Decision Making Units (DMUs) relays on the selection of the direction along which the distance from the efficient frontier is measured. Directional Distance Functions (DDFs) represent a flexible way to gauge the inefficiency of DMUs....

Envelopment Analysis (DEA) in this context allows the identification of inefficiencies sources and benchmark units. This paper … used DEA to measure the efficiency of farmers’ sample from Holambra, a São Paulo State municipality. Cultiva-ted area …, employment and machinery usage are the inputs and net inco-me is the output. DEA BCC is used in two models: global and by groups …

Efficiency evaluation of a Decision Making Unit (DMU) involves two issues: 1) selection of an appropriate reference plan against which to evaluate the DMU and 2) measurement of performance slack. In the literature, these issues are mixed in one and the same operation but we argue that it has...

This paper demonstrates that the bootstrap procedure suggested by Ferrier and Hirschberg (1997) gives inconsistent estimates. A very simple example is given to illustrate the statistical issues underlying nonparametric efficiency measurement and the problems with the Ferrier/Hirschberg approach,...

This article suggests a method for introducing a stochastic element into Farrell measures of technical efficiency as calculated via linear programming techniques. Specifically, a bootstrap of the original efficiency scores is performed to derive confidence intervals and a measure of bias for the...

Rewarding regulated firms based on their relative performance requires benchmarks that reflect how performance is affected by regulation. This paper demonstrates how parametric and nonparametric efficiency measures can be employed to produce benchmarks that account for the effects of regulation....
