These lectures aim to help readers understand the logics and nature of the main indicators of inequality and poverty, with special attention to their social welfare underpinnings. The key approach consists in linking inequality and poverty measurement with welfare evaluation. As concern for...

We propose a new Human Development Index that involves a number of changes with respect to the present one, even though it keeps the basic structure of the index (namely, preserving “health,” “education” and “material well-being” as the three basic dimensions of human development)....

This book deals with the analysis of production economies in which firms may exhibit increasing returns to scale, or other forms of non-convexities. The study focuses on the existence and efficiency of equilibrium allocations, and the comparison with the standard competitive equilibrium model. A...

This paper provides an extension of the Nash solution to NTU bargaining and rationing problems, allowing for non-convex, non-smooth utility possibility sets. We do so by interpreting the Nash solution as the maximiser of a weighted utilitarian social welfare function, in which the weights are...

There are two distinct "Scandinavian consensus" approaches to public good supply, both based on agents' willingness to pay. A Wicksell-Foley public competitive equilibrium arises from a negative consensus in which no change of public environment, together with associated taxes and subsidies...

This paper provides a characterization of the classical Talmud rule for bankruptcy problems by means of a new property, called securement, that imposes a lower bound on the awards that agents obtain. This property stipulates that no agent holding a feasible claim will get less than one nth of...

An input-output model with non-constant returns to scale and externalities is presented, and it is shown that in this model the non-substitution theorem is still valid. More precisely, the quantity side of the theorem, i.e. the proposition on efficiency, remains valid, while there can be no...
