This article computes the energy productivity changes of regions in Japan using total-factor frameworks based on data envelopment analysis (DEA). Since the traditional DEA-Malmquist index cannot analyze changes in single-factor productivity changes under the total-factor framework, we apply a new index proposed by Hu and Chang [2009. Total-factor energy productivity growth of regions in China. ...

The analysis of the composition of economic growth in the G7 countries has been motivated by the desire to identify regularities that contribute to explaining economic success. Such analysis must be carried out with a long term perspective, and the relevant production function should reflect existing world technology and not just domestic conditions. Moreover, in order to assess the relative pe...

Several different approaches to international comparison of Total Factor Productivity (TFP) have now emerged. Among these are the time-series approach, the panel approach, and the cross-section approach. This paper compares methodologies of these different approaches and results that have been obtained from their application. The comparison of results is conducted in the context of two samples,...

For period t, let qt = f(vt) + τt, where qt denotes measured output quantity, f(⋅) denotes a production function, vt = (v1t, ..., vnt) denotes a vector of n input quantities, τt denotes total factor productivity (TFP), and all variables are in natural-log form. Then, f(vt) = , for 0 < αit < 1 and = 1, is a Cobb-Douglas (CD) 1st-order log-form approximation of a production function. If f(⋅) is a...

Historically, commercial use of university research has been viewed in terms of spillovers. Recently, there has been a dramatic increase in technology transfer through licensing as universities attempt to appropriate the returns from faculty research. This change has prompted concerns regarding the source of this growth specifically, whether it suggests a change in the nature of university rese...

The per-case payment rates of Medicare's prospective payment system are annually updated. As one element of the update factor, Congress required consideration of changes in hospital productivity. In this article, calculations of annual changes in labor and total factor productivity during 1981-86 of hospitals eligible for prospective payment are presented using several output and input variants...

For several years researchers & practitioners have been concerned about the impact of investments in Information & Communication Technologies (ICT) on productivity. The research framework of neoclassical growth accounting is widely used in this area of research on IT & Productivity. While several studies have explored the relationship between investments in ICT and metrics such as GDP, the link...

The main objective of this paper is to decompose the productivity growth of Egyptian cotton production. We employ the stochastic frontier approach and decompose the changes in total factor productivity (CTFP) growth into four components: technical progress (TP), changes in scale component (CSC), changes in allocative efficiency (CAE), and changes in technical efficiency (CTE). Considering a sit...
