The estimation of production functions has been one of the more popular areas of applied econometrics. Recent work in duality theory which has linked production and cost functions has made this topic even more attractive. Typically, least squares (or some variant, such as two stage or generalized least squares) is used to estimate the model of interest in accordance with the assumption of a nor...

In economics, several parametric regression-based models have been proposed to measure the technical efficiency of decision making units (DMUs). However, the problem of misspecification restricts the use of these methods. In this paper, symbolic regression is employed to obtain the approximate optimal production function automatically using genetic programming (GP). Monte Carlo simulation is us...

When analyzing the productivity of rms one may want to compare how the rms transform a set of inputs x typically labor energy or capital into an output y typically a quantity of goods produced The economic e ciency of a rm is then de ned in terms of its ability of operating close to or on the production frontier which is the boundary of the production set The frontier function gives the maximal...

Production is the most fundamental activity in our economy. In this paper, a Cobb-Douglas production function is used as the mathematical model to describe the relationship among production, labor and capital. Two reliable production optimal control problems are studied. Algorithms to find dynamic optimal control intervals are provided with interval parameter presentations and interval computat...

Some propositions related to about growth theory are not valid for all production functions. This is the case estimation of total factor productivity based on accounting’s approach which easily verified with a Cobb-Douglas function, but difficult obtain CES function. In this paper, we will try do that using Moroccan data.

underutilized and overutilized hours of OR time [1,2]. According to macroeconomic theory, efficiency may be defined as the use of scarce resources to achieve all opportunities in production (output) [3]. Operating room efficiency also may be defined as the allocation of limited resources (labor, time, space, equipment) to maximize OR use. Efficiency also implies a tradeoff between the quantity ...

this paper uses the concept of meta-frontier to investigate the relationship between meta technology ratios (mtr) and different varieties in datepalms including; mazafati, rabi and zardan that are produced widely in sistan and baluchestan province of iran. we used a stratified sampling of 300 date farmers of this province in 2010, 2011 and 2012 and estimated a stochastic production frontier usi...
