This paper aims at studying, in the image space, an approximation of a vector optimization problem obtained by substituting the involved functions with their G-derivatives. It is shown that, under the hypothesis of G-differentiability, the existence of a semistationary point is equivalent to the...

In this paper we consider a vector optimization problem; we present some scalarization techniques for finding all the vector optimal points of this problem and we discuss the relationships between these methods. Moreover, in the linear case, the study of dual variables is carried on by means of...

We characterize the optimal investment decision and the stock value of an unlevered firm that holds the non-standard option of improving the growth rate of cashflows from its assets in place upon incurring an irreversible cost. The firm's investment policy and equity price are studied as a...

Ad oltre dieci anni dalla prima direttiva europea e mentre il mercato finale è arrivato alla sua apertura totale il bilancio delle liberalizzazioni sul piatto della concorrenza e della regolamentazione non è esaltante. Le Autorità incaricate di promuovere la concorrenza nei momenti cruciali...

The problem of taking into account the quality attributes of different goods has a long tradition in economics A strand of literature deals with the environmental impacts in the measurement of efficiency and productivity growth. Färe et al. (1989) indeed started what has become now a relatively...
