Bayesian and frequentist criteria fundamentally differ, but often posterior sampling distributions agree asymptotically. For the corresponding single-draw experiment, we characterize size of a certain hypothesis test (possibly nonlinear) inequalities. If null is that parameter lies in specified half-space, then test’s equals α; if subset above otherwise, may be equal to, above, or below α. Reje...

this study examines technical efficiency in iran's banking system using unbalanced panel data for 17 state and private banks during the 1997-2009 period. therefore, technical efficiency of banks was measured through estimating a translog cost function in the form of a panel sfa error compound model. then, the effect of underlying factors including both individual and structural (ownership/...

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...

Quality of service is of major economic significance in natural monopoly infrastructure industries. In this paper we present an efficiency analysis of electricity distribution networks from seven European countries. We apply the stochastic frontier analysis (SFA) method on multi-output translog input distance function models to estimate cost efficiency and scale economies. We show that introduc...

This paper considers an econometric approach to measuring substitutability of three types of energy, i.e. crude oil, electricity and diesel with capital and labour in the manufacturing sector of Greek industry during the period 1970]1990. A general dynamic framework is developed under the assumption that the structure of the production process is weakly separable in capital, labour and energy a...

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...

This study is primarily focused on the productivity impacts of the provision of infrastructure on the registered manufacturing sector in India. This is analyzed by estimating the cost elasticity of infrastructure inputs. For this purpose we postulate a variable cost function model for the manufacturing sector with cost as a function of the prices of the variable inputs, levels of output and inf...

In this research, the cosmetics industry’s economies of scale between 2018 and 2022 were explored by examining cost efficiencies 20 companies through a translog function model. The companies’ size was evaluated based on their total revenue assets. study also analyzed origin considering various components such as goods sold, operating costs, selling general expenses, well administrative expenses...
