Productivité agricole et rattrapage technologique : le cas des exploitations de grandes cultures du Nord-Pas-de-Calais

Blancard, Stéphane; Boussemart, Jean-Philippe - In: Cahiers d'Economie et de Sociologie Rurales (CESR) 80 (2006)

Un des principaux objectifs des différentes réformes successives de la PAC est de soumettre davantage l’offre agricole européenne aux signaux des marchés. De fait, la recherche de compétitivité devient une préoccupation majeure des agriculteurs. Les moins performants doivent rattraper...

Differential duality

Mantovi, A. - Facoltà di Economia, Università degli Studi di Parma - 2013

A framework for duality theory is set forth, based on the model-independent role of homotheties. An expansion vector field is introduced as global generator of pure expansion effects, in terms of which to deepen the differential aspects of preference symmetries, fundamental identities and...

Hospital organization and performance: a directional distance function approach

Falavigna, Greta; Ippoliti, Roberto; Manello, Alessandro - In: Health Care Management Science 16 (2013) 2, pp. 139-151

The present study considers the Italian healthcare system, investigating the aspects that might affect the efficiency of Italian hospitals. The authors analyze what influences a specific definition of efficiency, which is calculated maximizing healthcare production but minimizing potential...

How efficiently do U.S. cities manage roadway congestion?

Glass, Anthony; Kenjegalieva, Karligash; Sickles, Robin - In: Journal of Productivity Analysis 40 (2013) 3, pp. 407-428

We estimate efficiency and TFP growth for two measures of congestion and two measures of the monetary value of congestion for the largest 88 contiguous cities in the U.S. over the period 1982–2007. Using stochastic frontier analysis we find that the efficiency scores for congestion and the...

Measuring scale efficiency from a parametric hyperbolic distance function

Nahm, Daehoon; Vu, Ha - In: Journal of Productivity Analysis 39 (2013) 1, pp. 83-88

This paper shows how scale efficiency can be measured from an arbitrary parametric hyperbolic distance function with …-input distance function and from a multi-output and multi-input distance function, respectively. The method developed in the present …. Theorems applicable to an arbitrary parametric hyperbolic distance function are introduced first, and then their uses in …

Estimation and decomposition of inefficiency when producers maximize return to the outlay: an application to Norwegian fishing trawlers

Kumbhakar, Subal; Asche, Frank; Tveteras, Ragnar - In: Journal of Productivity Analysis 40 (2013) 3, pp. 307-321

This paper deals with estimation of a production technology where endogeneous choice of input and output variables is explicitly recognized. In particular, we assume that producers maximize return to the outlay (RO). For simplicity and tractability we start with a Cobb–Douglas transformation...

Assessing Brazil’s Cerrado agricultural miracle

Rada, Nicholas - In: Food Policy 38 (2013) C, pp. 146-155

Brazil’s emergence as a primary global agricultural producer is often credited to production expansion into soils of the Brazilian savannah or Cerrado. These soils are, however, deficient in important nutrients and prone to degradation, requiring input-intensive processes that suggest a low...
