In the paper we study a class of nonsmooth optimization problems arising in the theory of cardinality constrained portfolio analysis. The involved functions in this model arestrongly nondifferentiable; we give second order optimality conditions by C{1,1} approximations.

This paper presents a simple model in which debt management stabilizes the debt-to-GDP ratio in face of shocks to real returns and output growth and thus supports fiscal restraint in ensuring sustainability. The optimal composition of public debt is derived by looking at the relative impact of...

The theory of CSR argues that maximize the social and environmental efficiency of the firm is a prerequisite to economic sustainability. So the theory of CSR limelight one of the fundamental assumptions of the management sciences. The purpose of this contribution is to assess the meaning of...

In this paper we review some recent results concerning the approximations of distributionfunctions and measures on [0, 1] based on iterated function systems. The twodifferent approaches available in the literature are considered and their relations areinvestigated in the statistical perspective....

Our main objective with this paper is to explore business transfer as as potential source of innovation in Small and Medium-sized Enterprises (SMEs). The literature on the subject has mainly focused to business succession as process through which ownership and control is transferred between...

We propose a procedure to assess a measure for a latent phenomenon, starting from the observation of a wide set of ordinal variables affected by structured missing data. The proposal is based on Nonlinear PCA technique to be jointly used with an ad hoc imputation method for the treatment of...

The British privatisations were concentrated on the infrastructure industries of transport, communications and energy. It is important to assess the efficiency impact in a long-term context. The Milan study goes some way towards this but even better is to compare different countries of the...

L'esame dell'archivio amministrativo di una delle maggiori società di fornitura di lavoro interinale consente di osservare le specificità dell'offerta di lavoro temporaneo, rimaste in ombra negli studi realizzati finora sul lavoro temporaneo in Italia. I dati esaminati sono relativi alla fase...

In this paper we review alternative measure of intergenerational mobility, emphasizing the distinction between absolute, relative and ordinal mobility. We then compare the performance of various mobility indices using real data. From Treiman and Ganzeboom (1990) dataset we compare the degree of...
