Among today’s rich economies, per capita output levels diverged before converging to the levels of the frontier economy. Since frontier economies grew at stable rates, non-frontier economies display an S-shaped transition path. Along this transition, there are "catapult effects": longer episodes of stagnation are associated with faster subsequent rates of convergence to the frontier. Many of to...
A balanced panel of 83 airlines during 2011–2019, classified into (a) high perceived service quality and (b) low quality, was incorporated the Bayesian meta-frontier framework. Our findings were obtained from applying a novel method to data sourced ICAO Data+ Skytrax databases. We consistent efficiency meta-technology estimates, shedding light on airlines’ business models, products, services im...
The aim of this paper is twofold. First, to provide a statistical overview of the literature on public transit efficiency performance. Second, to statistically explain the variation in efficiency findings reported in the literature. To this end, first some key concepts of efficiency analysis will be introduced, while next the different frontier methodologies that are used in the literature will...
This paper studies regional productive performance differentials among 243 NUTS-2 European regions for the period 2003–11. Within last two decades technology gap between has increased considerably. Building on previous that have used data envelopment analysis (DEA) and which neglected national production structures pre-existing technological heterogeneity, we examine differences in by using a m...
Frontier techniques have been used to measure healthcare provider efficiency in hundreds of published studies. Although these methods have the potential to be useful to decision makers, their utility is limited by both methodological questions concerning their application. The aim of this paper is to search articles applying combined data envelopment analysis (DEA) and stochastic frontier analy...
In finance, the most efficient portfolio is tangency portfolio, which formed by intersection point of frontier and capital market line. This paper defines explores a time-varying under nonlinear constraints (TV-TPNC) problem as programming (NLP) problem. Because meta-heuristics are commonly used to solve NLP problems, semi-integer beetle antennae search (SIBAS) algorithm proposed for solving ca...
The conventional Cobb-Douglas production function model require strong assumptions such as the constant elasticity and the entire frontier efficiency. The varying elasticity production function is an useful extension but it does not take frontier efficiency into account, and the data envelope analysis model involves the use of linear programming methods to estimate the frontier efficiency where...
Abstract Background The energy generation efficiencies of thermal power and hydropower, which are the two main forces electric in China, important factors affecting conservation, emission reduction, green development country’s whole industry. Methods Considering regional differences multiple efficient decision-making units (DMUs), this research uses meta-Frontier super-efficiency slack-based me...
We study some structural and topological properties of the frontiers of objects in a certain class of discrete spaces, in the framework of simplicial complexes and partial orders. In a previous work, we introduced the notion of frontier order, which allows to define the frontier of any object in an n-dimensional space. The main goal of this paper is to exhibit the links which exist between fron...
