The paper uses a real option approach to investigate the potential impact of performance-based risk-sharing agreements for the reimbursement of new drugs in comparison with standard cost-effectiveness thresholds. The results show that the exact definition of the risk-sharing agreement is key in...

In this working paper we study some properties of a particular mapping in Rn related to an optimization problem with one equality constraint. We motivate the definition of the relevant mapping starting from a portfolio selection problem, in which we minimize the risk of an investment (the...

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...

The paper proposes a methodology to measure the characteristics of intermediate products when quality is multidimensional. It uses a general representation of the multioutput technology via directional distance functions and constructs quality indicators based on differences. The quality...

In this paper we investigate the valuation and optimal timing of the launch of two complementary/substitute products (or projects), one of which is a pilot product. As a first step, we study the problem from a strategic point of view and analyze the ability of the pilot product per se to create...

The paper designs an optimal payment system for a group of producers implementing it empirically. It shows how to implement the first best through higher prices for better quality commodities, deriving the optimal pricing schedule. It also takes into account producers' heterogeneity by modelling...

This paper compares dierent centralized collective models for maximizing the utility of a household from the point of view of the single members that compose it. We describe the collective maximization program as a vector optimization problem and analyze the household welfare and Pareto...

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...
