NONPARAMETRIC IDENTIFICATION AND ESTIMATION OF STOCHASTIC FRONTIER MODELS
… nonparametric identication and estimation of stochastic frontiermodels. It is composed of three chapters. The rst chapter investigates the identication and estimation of a cross sectional stochastic frontier model with Laplacian errors and unknown variance, which is built on a nonparametric …

Essays on Characterizing Inefficiency for Stochastic Frontier Models
<p>This dissertation consists of three essays on stochastic frontier models in characterizing inefficiency for a cross section of firms in essays one and three and a set of firms overtime in essay two. The first essay looks at stationary points for several models used in stochastic frontier …

A Normal Truncated Skewed-Laplace Model in Stochastic Frontier Analysis
<p>Stochastic frontier analysis is an exciting method of economic production modeling that is relevant to hospitals, stock markets, manufacturing factories, and services. In this paper, we create a new model using the normal distribution and truncated skew-Laplace distribution, namely the …

FDI and Technical Efficiency in Manufacturing Firms: A Stochastic Frontier Approach
<p>In this paper, firm-level data from manufacturing sector in five African countries is obtained to estimate the impact of foreign direct investment (FDI) on firm’s technical efficiency. Unbalanced panel data over period of 1991-2003 shows that the existence of FDI has a significant impact on …

An evaluation of hospital efficiency in Nigeria : a stochastic frontier approach
… studied. The main thrust of analysis is the stochastic frontier process, which also incorporates an efficiency effects model. The choice of this model, above all else, is because it provides numerical efficiency estimates and thus provides quantifiable proof of how well poorly Nigerian …

Measurement and evaluation of managerial efficiency in English league football : a stochastic frontier analysis
… we explore the growing literature on production frontier analysis. We are particularly interested in the available estimation procedures and how previous sports studies have utilised this framework in estimating efficiency. A discussion of the football industry is the focus of Chapter 3, while in …

Measuring Efficiency for Egyptian Textile and Apparel Industry Using Stochastic Frontier Analysis and Data Envelopment Analysis
… in the Egyptian textile and apparel industry via stochastic frontier analysis (SFA) and data envelopment analysis (DEA). Differences between the SFA and the DEA can lead to different estimates for some, or all of the units in an analysis. Measuring efficiency through production process, (inputs …

Assessing cost efficiency and economies of scale in the European banking system, a Bayesian stochastic frontier approach
… for which we identify fourteen nation-specific frontiers and also perform cross country comparisons under a common frontier assumption. Our interest in the subject is twofold. At the nation level, cost e_x000E_fficiency influences the relative competitiveness of banks, setting the profile of the …

Optimum experimental designs for models with a skewed error distribution: with an application to stochastic frontier models
… type is sometimes called 'composed' error. A stochastic frontier model is an example of a model that possesses such an error structure. The systematic error, U, in a stochastic frontier model represents the economic efficiency of an organisation. Three methods for approximating information …

Assessing technical inefficiency in private, not-for-profit, bachelor's and master's universities in the United States using stochastic frontier estimation
… of institutions that can be identified using a stochastic frontier estimation (SFE) method and to evaluate the applicability of SFE to higher education. Categories of expenditures were utilized to create a production frontier against which the inefficiency of individual institutions to produce …

Specification tests and a reformulation of frontier models: An alternative approach to efficiency estimation
… and the formulation of composite error stochastic frontier model by Aigner, Lovell and Schmidt (1977), a substantial amount of research work has been performed measuring firm's technical inefficiency using this model with various distributional assumptions of technical inefficiency. Most …

Impacts of great western development on agricultural production in the west of China
… the Chinese agricultural production, I use the stochastic frontier production function. This approach is used widely in the field of economics in areas of measuring technical efficiency and policy effects in an industry with random shocks. I accompany this approach with several economic theories …

Three empirical essays on mergers and regulation in the telecommunications industry
… for 25 ILECs over the period 1996-2005 using stochastic frontier analysis with a time-varying inefficiency model. In addition, we conduct a comparison of indices between the stochastic frontier analysis and the Malmquist index method. The empirical results indicate that the sample of …

Production, efficiency and managerial selection of workers into peer networks
… process.</p> <p>The first chapter, entitled "Stochastic Frontier Models with Network Selectivity," develops a model where workers produce output through peer-effect networks, while managerial selectivity of workers affects worker inefficiency. The intuition behind this model is that managers …

How efficient are Kenyan hospitals? : an application of frontier analysis techniques
… hospitals using data envelopment analysis and stochastic frontier analysis. Panel data were collected from 27 public and faith-based hospitals between 2008 and 2012. Data envelopment analysis (DEA), a non-parametric approach and stochastic frontier analysis (SF A) a parametric approach were …

How is Sectoral FDI Affecting Firms’ Performance in Mozambique?
… foreign spillovers were not automatic. Using a stochastic frontier model, to measure efficiency, I find that in general foreign firms tend to be more efficient than domestic firms. However, using this model, it seems that domestic firms’ efficiency is not affected by the presence of foreign …

Structure, Productivity Growth and Spillover Effects: An Empirical Investigation of Indonesian Manufacturing
… of individual firms is estimated using stochastic frontier approach to panel data. Panel data, which are time series on a set of cross-sectional data, offer several major advantages over conventional cross-sectional or time series data. The study fails to find a robust spillover effects …
