In this paper, firm profit loss is decomposed as the sum of two terms related to the output price uncertainty (price expectation error and risk preference), plus one extra term expressing technical inefficiency. We then describe the implementation of our theoretical model in a robust data...

Since Akerlof’s theory of lemons, economists have viewed quality uncertainty as an informational advantage for sellers. Drawing on frontier techniques, we propose in this paper a simple method for measuring inefficiency of both sellers and buyers in markets for goods with different levels of...

Livestock supply must challenge the growth of final demand in the developing countries. This challenge has to take into account its ecological effects since the dairy and livestock sectors are clearly pointed out as human activities which contribute significantly to environmental deterioration....

This study estimates productivity gains and their distribution among inputs and outputs for American industries over the period 1987-2011 using the traditional surplus accounting method. Total Factor Productivity (TFP) change is traditionally defined as the growth rate of output minus the growth...

Thepurpose of this short article is to simplify goodness-of-fitmethods to obtain qualitative information about returns to scalefor individual observations. Traditional and new goodness-of-fitmethods developed for estimating returns to scale on nonparametricdeterministic reference technologies...

This paper aims at assessing the extent to which M&As in European banking sector over the period 1996–2003 result in two simultaneous catching up and convergence processes of consolidating groups. First, do the M&As significantly contribute to the consolidating banks to catch-up with the...

Hospital productivity has been a research topic for over two decades. Whereas much has been learned regarding cost, technical, scale, and allocative efficiency as well as the impact that weakly disposable inputs/outputs have on hospital behavior, we expand on this research by examining size and...

[fre] Comparaison des différentes mesures d'efficacité technique : une application aux centres hospitaliers français . par Hervé Leleu et Benoît Dervaux . L'engouement pour les techniques non paramétriques d'estimation de frontières de production dans le domaine hospitalier tient à leur...

This paper extends the recent work by Frei and Harker on projections onto efficient frontiers (1999) in three ways. First, we provide a formal definition of the production set as the intersection of a finite number of closed halfspaces. We emphasize the necessity of a complete enumeration of the...
