In this study we analyze the evolution of operating cost inefficiency for the English and Welsh water industry over the period 1995-2001 by estimating an heteroskedastic stochastic variable cost frontier. The main aim of this paper is to provide an overall picture of the industry cost inefficiency, as we consider both the water and sewerage companies and the smaller water only companies. The ma...
Bounding the inefficiency of selfish routing has become an emerging research subject. A central result obtained in the literature is that the inefficiency of deterministic User Equilibrium (UE) is bounded and the bound is independent of network topology. This paper makes a contribution to the literature by bounding the inefficiency of the logit-based Stochastic User Equilibrium (SUE). In a stoc...
− A theoretical framework is developed for decomposing partial factor productivity and measuring technical inefficiency when the underlying technology is characterized by factor non-substitution. With Farrell’s (1957) radial index of technical inefficiency being inappropriate in this case, Russell’s (1985; 1987) non-radial indices are adapted to measure technical inefficiency in a Leontief mode...
to be found in these pages the latest facts and figures as to what is actually happening but they also reveal how the problem is presenting itself to those most closely at grips with it, and what is the angle from which it is being approached. From the report before us we learn that so far as the working of Section J of the Mental Deficiency Act is concerned, the position is distinctly improvin...
We present evidence for the presence of a transition in the accretion properties of radio-loud sources. For a sample of radio galaxies and radio–loud quasars, selected based on their extended radio properties, the accretion rate is estimated from the black hole mass and nuclear luminosity. The inferred distribution is bimodal, with paucity of sources at accretion rates, in Eddington units, of o...
This study uses a generalized stochastic frontier framework to model a multiple-output rice production system and analyses farm-level technical inefficiency of rice farming in Assam, India. Primary data for this study was collected in 2009-2010 from 310 farm-households in four non-contiguous districts of Dhubri, Morigaon, Dibrugarh, and Cachar that are located in different agro-climatic regions...
