We consider a family of exchange economies where consumers have multiprior preferences representing their ambiguity aversion. Under a linear independence assumption, we prove that regular economies are generic. Regular economies exhibit enjoyable properties: odd finite number of equilibrium...

This essay seeks to develop an integrated account of the workings of statistical mechanics and thermodynamics as a theory of economic equilibrium. It begins with a probabilistic description of general systems (made out of numerous elements), based on the practice of statistical physics and the...

The paper studies the effects of green tax reforms within a walrasian computable general equilibrium model of the Italian economy calibrated on a microconsistent data set derived from the Input-Output table for the year 1990. Tax reforms increase taxation on the energy sector either through an...

This article concerns the existence of equilibrium in a two-period model with general personal and corporate tax structures. We show that an equilibrium exists if there is a price system under which no consumer or firm has an arbitrage opportunity. The model can be modified to handle non convex...

Fabio Petri's Microeconomics for the Critical Mind (2021) is an impressive tour de force in the field of microeconomic theory. It manifests the author's command of cutting edge analytical tools, concepts, and theoretical approaches both in the mainstream and in the heterodox literature. The book...

To design an optimal education policy, it is essential to account for the fertility differential between the poor and the rich because it affects the human capital investment through the child quantity-quality tradeoff of children. We develop a dynamic general equilibrium in which parents choose...

The Strategic Market Game (SMG) is the general equilibrium mecha-nism of strategic reallocation of resources. It was suggested by Shapley and Shubik in a series of papers in the 70s and it is one of the fundamentals of contemporary monetary macroeconomics with endogenous demand for money. This...

The Italian economist Enrico Barone (1859- 1924) is best known for his contributions to marginal productivity theory and the socialist planning debate. This paper analyzes Barone’s contributions to the theory of perfect competition which are largely ignored in the secondary literature. It...

This chapter examines government policy alternatives for protecting the environment. We compare environmentally motivated taxes and various non-tax environmental policy instruments in terms of their efficiency and distributional impacts. Much of the analysis is performed in a second-best setting...
