In this paper we advocate using the latent class model (LCM) approach to control for technological differences in traditional efficiency analysis of regulated electricity networks. Our proposal relies on the fact that latent class models are designed to cluster firms by uncovering differences in...

This paper provides a parametric decomposition of a generalized Malmquist productivity index which takes into account scale economies. Unlike Balk (2001), the contribution of scale economies to productivity change is evaluated without recourse to scale efficiency measures, which are neither...

In this paper, we study to what extent a movie’s box-office receipts are affected by the temporal distribution of rival films. We propose a reduced-form empirical model to measure and test competition effects among films released close to each other in a standard regression framework. Such an...

We focus on the importance of the assumptions regarding how inefficiency should be incorporated into the specification of the data generating process in an examination of a sector's production or efficiency. Drawing on the literature on non-nested hypothesis testing, we find that the model...

This paper analyses whether self-reported valuation of goods is an adequate proxy for underlying tastes. In this case, different self-reported appraisals, which we can associate with different utility functions, would imply different demand curves. To estimate these kinds of relationships we...

Let u ≥ 0 be technical inefficiency, let z be a set of variables that affect u, and let δ be the parameters of this relationship. The model satisfies the scaling property if u(z, δ) can be written as a scaling function h(z, δ) times a random variable u* that does not depend on z. This...
