This study estimates Malmquist index of total factor productivity change of 14 major general insurers in India over the period 2009–10 to 2016–17 over 7 annual windows. The study decomposes total factor productivity index into its constituent components, using several approaches including Färe et al. (1989, Productivity Developments in Swedish Hospitals: A Malmquist Output Index Approach. Carbondale: Department of Economics, Southern Illinois University; 1992, Journal of Productivity Analysis 3(1): 85–101), Färe et al. (1994, American Economic Review 84(1): 66–83), Ray and Desli (1997, American Economic Review 87(5): 1033–39) and Wheelock and Wilson (1999, Journal of Money, Credit and Banking 31(2): 212–23). Furthermore, the study uses bootstrap data envelopment analysis (DEA) method to obtain bias-corrected point and interval estimates of Malmquist index and its components. Finally, the study makes a comparison of productivity performance between public and private sector insurers. The results indicate a modest growth in total factor productivity during the period contributed mainly by efficiency changes. The private sector insurers performed better than the public sector in terms of productivity growth. The variations in productivity performance indicate that insurer scale of activity can affect their performance. JEL Classification: G-23, C-61, D-21

The purpose of this paper was to study the productivity where renewable energy resources and non-renewable resources for generating electricity in power plants connected to the national grid of Nicaragua were used.  This article analyzed the total factor productivity of Bioeconomy for the generation of electricity from plants using sugarcane bagasse (biomass) as a renewable resource and petroleum. The data envelopment analysis (DEA) and the Malmquist index were used to measure the total factor productivity of power generation utilities connected to the national grid of Nicaragua. The results obtained by comparing sugar mills connected to the SIN was that Monte Rosa mill has a higher rate of increase in productivity due to the change of total factor productivity and when comparing thermal plants that employ petroleum products in power generation, the more efficient were ALBANISA, GECSA and TIPITAPA POWER; but when comparing thermal plants and some using renewable energy San Antonio sugar mill and ALBANISA were more efficient.
