On Estimation of Monotone and Concave Frontier Functions
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 eeciency of a rm is then deened 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...

متن کاملDuality between quasi-concave functions and monotone linkage functions
A function F defined on all subsets of a finite ground set E is quasiconcave if F (X∪Y ) ≥ min{F (X), F (Y )} for all X, Y ⊂ E. Quasi-concave functions arise in many fields of mathematics and computer science such as social choice, theory of graph, data mining, clustering and other fields. The maximization of quasi-concave function takes, in general, exponential time. However, if a quasi-concav...
متن کاملMaximum Likelihood Estimation of Econometric Frontier Functions*
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...
