this paper is concerned with the estimation of total factor productivity (tfp) growth for the iranian electric utilities during the period 1980-1993 on the basis of panel data. a translog cost function is used which accommodates firm - specific variability through a one - way error component model. the results show that the iranian electricity supply industry experienced increasing returns to s...

Recent financial liberalization in Taiwan has caused local banks to face major structural changes. This paper examines the cost structure of 36 local banks in Taiwan using the translog cost function and attempts to identify suitable operating strategies for cost reduction and performance improvements. Results indicate scale economies for small and large-sized banks and scope economies for all b...

The focus of the Japanese local telecommunications policy is moving toward how to solve the problem of the digital divide that accompanies the spread of high-speed and broadband services. This paper estimates the translog cost function of two outputs, the standard telephone service and the leased circuit service, and measures the regional gap of those stand-alone costs and incremental costs. Th...

Based on stochastic frontier analysis and translog input distance function, this paper examines the total factor energy efficiency of China’s industry using input-output data of 30 subindustries from 2002 to 2014, and decomposes the changes in estimated total factor energy efficiency into the effects of technical change, technical efficiency change, scale efficiency change and inputmix effect. ...

This paper explores the link between trade liberalization and firms’ performance in Egypt combining macro micro data. Using Economic Census of 2013, we examine association tariffs non‐tariffs measures (NTM) imposed on intermediate input sand total factor productivity (TFP). In a first step TFP is estimated as residual Cobb‐Douglas/Translog production function thesecond, regressed weighted NTM i...

This paper extends the existing research on real estate investment trust (REIT) operating efficiencies. We estimate stochastic-frontier, panel-data models specifying a translog cost function. The specified model updates the cost frontier with new information as it becomes available over time. The model can identify frontier cost improvements, returns to scale, and cost inefficiencies over time....

abstract since about 34% of areas under rice cultivation in whole country is attributed to gilan; in this study we pay attention to some economical dimensions, especially economic values of inputs in this region. data were collected from 80 rice producers in 2007-2008. consider to importance the parametric approach in production structure and factors demand, applying seemingly unrelated regress...
