The Efficiency of the Italian Banking System from 2006 to 2010: an Application of the Stochastic Frontier Approach
No full textA note: Constant Market Share Analysis
Full text linkAbstract Constant Market Share Analysis (CMSA) is a method which decomposes the variation of market shares of any trader country. The more recent version is proposed by Fagerberg and Sollie (1985) that avoids some limits deriving from previously specifications. After explicating how CMSA works, this note presents some applications to the Italian case and its most important contribution, which is the formal derivation of market share variation
A proof of the Ghoussoub-Preiss theorem by the ε−perturbation of Brezis-Nirenberg
Full text linkIn this note, a proof of the Ghoussoub-Preiss theorem is presented by using the epsilon-perturbation as introduced by Brezis-Nirenb erg. Thus, besides the deformation lemma, other advanced tools such as the Radon mea-sures space, sub-differential, or the theory of non-differentiable functions, are avoided. Our new argument is a lemma of local type which is used in com-bination with other main ingredients like the Ekeland variational principle and the pseudo-gradient lemma, for which a new proof is proposed as a consequence of the Michael selection theorem

Constant Market Share Analysis. A note
No full textConstant Market Share Analysis (CMSA) is a method which decomposes the variation of market shares of any trader country. The more recent version is proposed by Fagerberg and Sollie (1985) that avoids some limits deriving from previously specifications. After explicating how CMSA works, this note presents some applications to the Italian case Two are the most important contribution of this paper. First, it includes a complete framework on CMSA. Second, the formal derivation of market share variation is proposed
Three solutions to a Neumann problem for elliptic equations involving the p-Laplacian
No full textIn this paper, we establish the existence of three solutions to a Neumann problem involving the p-Laplacian. The technical approach is mainly based on a three critical points theorem
