This stuely aflempts to measure the prodllctivi~y of Ihe life insurance inelustry by employing the non-parametric Malmquist Index approach. The ]inding shows that despite the productivity growth in the insurance industry, it is relatively loll' compared to the real economic growth experienced by Malaysia. Like the mallufacllfring sectol; thefurure growth of this indusll~y 1V0uld depend on its a...

We propose a function decompositionmodel, called intrinsic mono-component decomposition (IMD). It is a continuation of the recent study on adaptive decomposition of functions into mono-components (MCs). It is a further improvement of two recent results of which one is adaptive decomposition of functions into modified inner functions, and the other is decomposition by using adaptive Takenaka-Mal...

This paper develops an index for comparing the productivity of Groups of operating units in cost terms when input prices are available. In that sense it represents an extension of a similar index available in the literature for comparing groups of units in terms of technical productivity in the absence of input prices. The index is decomposed to reveal the origins of differences in performance ...

Environmental problem is a worldwide focus, so as the effect of environmental regulation on economic. In this paper, we constructed a model including energy consumption and integrated pollutant emissions of "Three wastes" as "bad" output. This paper used Malmquist–Luenberger based on directional distance function to measure TFP and environmental regulation cost of Chinese 36 industries from 200...

This study examines the productivity changes of decision making units in situation whereinput price vectors are varying between them and inputs are heterogeneous; that is a noncompetitivemarket. We present a directional measure of cost Malmquist productivity indexwhere incorporates the decision maker's preference over productivity change over time. Asimple numerical example is designed to illus...

Data envelopment analysis (DEA) based productivity indexes models are widely applied to evaluate the of decision-making units over a period. This study proposes index for evaluating environmentally sensitive growth while excluding possibility spurious technical regress. innovative has been created by combining directional distance functions, sequential DEA, undesirable data, and concept interva...

The aim of this paper is to present a novel heart beat detection algorithm using rational modelling of ECG signals. The algorithm considers several candidate beat locations. For a given candidate a rational model is fitted to the ECG signal by means of numerical optimization and Fourier partial sums with respect to the Malmquist-Takenaka system. The resultant model parameters are used as a basi...

A primal index of productivity change is introduced which decomposes exactly in three components: technical change, technical efficiency change and average scale economies (radial scale change). The proposed index is invariant to movement along indifference surfaces and it collapses to the Malmquist index if the technology is locally constant returns to scale. It is the best linear approximatio...
