Measuring Productivity When Technologies are Heterogeneous: A Semi-Parametric Approach for Electricity Generation

“…a technology with considerable capacity installations to possess higher rates of technical change, although no translation into overall productivity gains is detected. Similar to Heshmati et al (2014), the results indicate no productivity gains for mature technologies, but unlike Heshmati et al (2014), no stable downward trend in productivity is detected. We conclude that the StoNED approach combined with the proposed framework produces good estimates of productivity changes.…”

“…As Rubin et al (2015) and Jamasb (2007) illustrate, evolving technologies, such as biomass and waste to electricity, show higher learning rates than mature technologies, such as coal and lignite combustion technologies. Other plant-level studies question whether such learning rates actually transform into productivity gains finding either low levels of technical progress (Atkinson and Primont, 2002;Genius et al, 2012) or even technical regress (Oh, 2015;Heshmati et al, 2014). In contrast, See and Coelli (2013) find considerable technical productivity growth for mature technologies as a result of capacity installations.…”

“…In the empirical literature on power plant productivity, results generally indicate relatively small magnitude productivity changes in developed economies. For example, Heshmati et al (2014) find productivity decline between 1995 and 2006 for Korean electricity generation, and Atkinson and Primont (2002) find only small productivity gains between 1961 and 1997 for United States electricity generation. Rungsuriyawiboon and Stefanou (2008) and Genius et al (2012) obtain similar results, i.e.…”

Technical efficiency and CO2 reduction potentials — An analysis of the German electricity and heat generating sector

“…Finally, the Korean energy generation sector is analyzed in several studies. Heshmati et al (2014) use a semiparametric model to assess the effect of a power plants' characteristics on its productivity based on a panel approach. In addition to technical regress in the sector, results indicate a considerable heterogeneity in the plants' output response to changes in the production factors.…”

What is the impact of problem loans on Japanese bank productivity growth?

“…There has been extensive theoretical and empirical research into the field of firm efficiency and productivity (Heshmati, Kumbhakar, & Sun, ; Subal C. Kumbhakar & Tsionas, ; Sun, Kumbhakar, & Tveterås, ). In terms of bank efficiency and productivity, the outbreak of the global financial crisis has driven a surge of banking studies (Matousek, Rughoo, Sarantis, & Assaf, ; Tsionas, Assaf, & Matousek, ), unfolding the paramount importance of financial intermediaries within the economic system.…”
