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. The interest in this research is on determining preand post-...

______________________________________________________ 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...

background: due to the increasing health care costs, the issue of productivity in hospitals must be taken into great consideration in order to provide, preserve and promote public health services. thus, increasing the level of productivity must become the main aim of any hospital. objective of this study is to determine the total factor productivity and its components over the period under the ...

the performance of a supply chain can be evaluated in either a cross-sectional or a time series manner, and data envelopment analysis is a useful method for both types of evaluation. in this paper we develop an index and indicator of productivity change that can be used with radial and non-radial models for supply chain malmquist index. the supply chain malmquist productivity index (scmpi) can ...
