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...

The main aim of this paper is to determine the factors which enhance or temper firms’ private incentives to use communications technologies that are characterised by network externalities and allow firms to influence their rate of technological change or total factor productivity (TFP). As regards the impact of the network effect on TFP, we find that when the externality parameter is low, a sli...

Our paper analyzes the causal links between human capital accumulation and growth in total factor productivity (TFP). In particular, it tests the NelsonPhelps hypothesis that human capital is crucial in enabling the imitation of technologies developed at the frontier. To this end we calculate TFP for a sample of 86 heterogeneous countries over the period 1960-1990 and investigate whether there ...

The present study used different categories of organized sector manufacturing industries pooled data for the periods of 1981-82 and 2007-08 in Haryana state (India). The present undertaking seeks to analyze the inter-temporal and inter-industry comparison of total factor productivity (TFP) measured by Malmquist productivity index - an application of DEA which calculates the indices of TFP and i...
