A global Malmquist-Luenberger productivity index

This paper introduces an alternative environmentally sensitive productivity growth index, which is circular and free from the infeasibility problem. In doing so, we integrated the concept of the global production possibility set and the directional distance function. Like the conventional Malmquist-Luenberger productivity index, it can also be decomposed into sources of productivity growth. The suggested index is employed in analyzing 26 OECD countries for the period 1990–2003. We also employed the conventional Malmquist-Luenberger productivity index, the global Malmquist productivity index and the conventional Malmquist productivity index for comparative purposes in this empirical investigation.     

A metafrontier approach for measuring Malmquist productivity index

This paper presents an alternative framework for the decomposition of the Malmquist productivity index by using the concept of a metafrontier. The approach employed allows the calculation of technical efficiency changes, as well as technical changes, for economic agents operating under different technologies. It also enables the computation of the technological gap and its changes for economic agents operating under different technologies. This framework is applied to the analysis of panel data on 58 countries over a period of 31 years from 1970 to 2000. The empirical results show that Asian countries have attempted to move towards the frontier technology and that European countries have taken the lead in the world frontier technology.
