"The book uses distance functions, a generalization of the more familiar production function, as the theoretical and empirical tools to construct Lerner indexes of market power in both the input and output markets. The use of distance functions enables us to explicitly account for the effects of...

In this paper, we develop a computational procedure for the hyperbolic distance function (HDF) within the nonparametric framework of data envelopment analysis. We convert the nonlinear HDF model under variable returns to scale into an equivalent conic optimization problem with linear constraints...
