Relative Efficiency, Scale Effect, and Scope Effect of Public Hospitals: Evidence from Australia Using the 1997-1998 New South Wales public-hospitals comparison data, we investigate the hospital-level inefficiency by applying a stochastic-frontier multiproduct cost function. We use a flexible translog cost function to reduce the measurement errors of the outputs of the hospital. The main findin...

This paper estimates a translog stochastic frontier production function in the analysis of all 48 contiguous U.S. states in the period 1970-1983, to attempt to measure and explain changes in technical efficiency. The model allows technical inefficiency to vary over time, and inefficiency effects to be a function of a set of explanatory variables in which the level and composition of public capi...

This paper develops a tractable theoretical framework for analyzing the substitutability between different advertising media, the extent of marketing spillovers in the market, the allocative efficiency of advertising spending, and the sources of total advertising productivity and sales growth. Maintaining the separability assumption between sales and production technology, the proposed methodol...

Keywords: Jet aircraft Fuel price Operating cost Leontief technology Translog a b s t r a c t Investigation of the airline response to a fuel price increase is in effect an investigation of the role of variable interactions in aircraft cost models. We examine the impact of fuel price on aircraft costs and airline operational strategies by developing two classes of operating cost models for jet ...

Purpose This study investigates the interrelationships between efficiency, competition and risk in Chinese banking industry. Design/methodology/approach Parametric stochastic frontier analysis is used to estimate bank efficiency; Lerner index as indicator; accounting ratios a translog function are measure different types of finally, three-stage least square estimator investigate interrelationsh...

Several common flexible functional forms are evaluated for Texas agricultural production utilizing three procedures. Nested hypothesis tests indicate that the normalized quadratic is the marginally-preferred functional form followed by the generalized Leontief. Predictive accuracy results are ambiguous between the generalized Leontief and the normalized quadratic. Statistical performance favors...

This paper aimed to study how industrial air pollution impacts crop yield by investigating the relationship between output and changes in factors. A translog production function was estimated context of stochastic frontier analysis using data collected from a field survey case corn. The interaction factors as well impact on analyzed numerical simulation, followed estimation economic losses corn...

Rodrik (2018) hypothesises that technology used in global value chains (GVCs) is biased against the use of unskilled workers. To test this hypothesis, we introduce a GVC production function which final output produced by means factor inputs from all countries participate GVC. In contrast, previous studies only consider one stage using single country. We derive substitution elasticities and labo...
