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...

Measuring the performance of business processes in the financial services sector can be tackled from different perspectives. The viewpoint of efficiency is one of them. This paper focuses on the analysis of process efficiency and proposes a new methodology for measuring process efficiency and for further identifying drivers of process inefficiency. It is suitable for a specific perspective on p...

In this paper, we provide a characterization of interim inefficiency in stochastic economies of overlapping generations under possibly sequentially incomplete markets. With respect to the established body of results in the literature, we remove the hypothesis of two-period horizons, by considering longer, though uniformly bounded, horizons for generations. The characterization exploits a suitab...

It is known that the incompleteness of asset markets causes inefficiency in almost every equilibrium. Yet unexplored is the ”size” of this inefficiency. The size of a Pareto improvement is the total willingness to pay for it, out of current consumption. Inefficiency is the maximum size of any Pareto improving reallocation. Inefficiency of US consumption in middle age is computed to be 10-11% of...

PURPOSES To assess the relationship between hospitals' X-inefficiency levels and overall care quality based on the National Quality Forum's 27 safe practices score and to improve the analytic strategy for assessing X-inefficiency. METHODOLOGY The 2005 versions of the American Hospital Association and Leapfrog Group's annual surveys were the basis of the study. Additional case mix indices and ...

This article analyzes the consequences of tourism specialization on efficiency in hotel sector. The evidence found other sectors and economies supports goodness specialization. Nevertheless, tourism-led have particular issues that need to be addressed such as seasonality lack significant tradable competitive activities could trigger spillover effects services. Spain provides a suitable context ...
