This paper provides simulation evidence concerning some statistical properties of two different approaches to technical efficiency estimation for multipleoutput production under noisy conditions: The Ray Frontier Approach (RFA) from Löthgren (1997) and DEA+ proposed in Gstach (1996). RFA, unlike earlier approaches in the realm of stochastic frontier analysis, is capable of efficiency estimation...

 The importance of community's health followed by the consideration of endogenous growth models has led to an increase in health expenditure of countries to speed up economic growth and development. This has made the efficiency of health production function to an essential issue especially in developing countries. Based upon this, the present study with employing the stochastic frontier analysi...

We consider the optimal portfolio selection problem in a multiple period setting where the investor maximizes the expected utility of the terminal wealth in a stochastic market. The utility function has an exponential structure and the market states change according to a Markov chain. The states of the market describe the prevailing economic, financial, social and other conditions that affect t...

the different model specifications have been proposed to estimate time-varying technical efficiency in the last two decades. these models have resulted different efficiency scores based on their built-in specifications. this study investigates the temporal pattern of technical efficiency based on cornwell, sickles, and schmidt (css, 1990) as well as lee and schmidt (ls, 1993) models. in order t...

• We compute estimates of inefficiency when its distribution is unknown in Stochastic Frontier Models (SFMs) and Data Envelopment Analysis (DEA). Our procedure based on the Fast Fourier Transform (FFT) utilizes empirical characteristic function. The new techniques perform well Monte Carlo experiments. They deliver reasonable results an application to large U.S. banks. Deconvolution DEA scores w...
