Organizational performance evaluation is a crucial factor in making strategic decisions for the future. To plan economic growth, it important to measure efficiency and productivity of organizations. Efficiency key indicator evaluating optimal units. Petrochemical companies are vital components country's economy their operations contribute growth progress different sectors. In countries where re...

This study measures the quality-adjusted hospital efficiency and productivity index of a production unit. We propose a non-radial output-oriented directional distance function approach to analyze Taiwan’s hospital productivity, which embeds the quality of care and environment variables simultaneously. There are two major advantages of this model. First, it considers all the radial and nonradial...

malmquist productivity index (mpi) is a numeric index that is of great importance in measuring productivity and its changes. in recent years, tools like dea have been utilized for determining mpi. in the present paper, some models are recommended for calculating mpi when there are just ratio data available. then, using dea and dea-r, some models are proposed under the constant returns to scale ...

The conventional Malmquist productivity index (MPI) measures the performance improvement of a production system between two periods, where the system is treated as a black box, ignoring the internal operations of the component processes. Based on a relational model of the data envelopment analysis (DEA) for measuring the system and process efficiencies, this paper develops a methodology for cal...

We examine productivity growth of for-hire general freight trucking firms from 1999 to 2003. We find that trucking firms, which are often considered to be competitive, are not necessarily technically efficient. Moreover, firms’ productivity growth over the five-year period was stagnant despite embracement of new technologies by the industry. We conclude that positive technical change was largel...

Paul Rouse and Martin Putterill Department of Accounting and Finance The University of Auckland New Zealand [email protected] ______________________________________________________________________ Abstract In 1989 several hundred New Zealand local government authorities were amalgamated into less than one hundred larger entities.

______________________________________________________ Abstract The purpose of this study was to analyse the development of productivity and efficiency in the production of hospital care in Finland during the period 1988-1994. A special interest was directed to the impact of health care financing reform in 1993. The analysis is based on the Malmquist index approach using linear programming. Pos...

‎in this paper‎, ‎we give some necessary conditions for a complex‎ ‎difference equation of malmquist type‎ $$‎sum^n_{j=1}f(z+c_j)=frac{p(f(z))}{q(f(z))}‎,$$ ‎where $n(in{mathbb{n}})geq{2}$‎, ‎and $p(f(z))$ and $q(f(z))$ are‎ ‎relatively prime polynomials in $f(z)$ with small functions as‎ ‎coefficients‎, ‎admitting a meromorphic function of finite order‎. ‎moreover‎, ‎the properties of finite o...
