Specification and estimation of multiple output technologies: A primal approach

Kumbhakar, Subal C. - In: European Journal of Operational Research 231 (2013) 2, pp. 465-473

production function, input (output) distance function, input requirement function are considered. We show that all these …) distance function can not be treated as exogenous (uncorrelated with technical inefficiency) resulting inconsistent estimates … of the input (output) distance function parameters. (ii) Even if input (output) ratios are exogenous, estimation of the …

On the inconsistency of the Malmquist–Luenberger index

Aparicio, Juan; Pastor, Jesus T.; Zofio, Jose L. - In: European Journal of Operational Research 229 (2013) 3, pp. 738-742

Apart from the well-known weaknesses of the standard Malmquist productivity index related to infeasibility and not accounting for slacks, already addressed in the literature, we identify a new and significant drawback of the Malmquist–Luenberger index decomposition that questions its validity...

Total-factor carbon emission performance of fossil fuel power plants in China: A metafrontier non-radial Malmquist index analysis

Zhang, Ning; Choi, Yongrok - In: Energy Economics 40 (2013) C, pp. 549-559

This paper proposes the metafrontier non-radial Malmquist CO2 emission performance index (MNMCPI) for measuring dynamic changes in total-factor CO2 emission performance over time. The MNMCPI method allows for the incorporation of group heterogeneity and non-radial slack into the previously...
