In this paper, we establish two different characterizations of Walrasian expectations allocations by the veto power of the grand coalition in an asymmetric information economy having finitely many agents and states of nature and whose commodity space is a Banach lattice. The first one deals with...

The focus of this study is on black markets which provide an important segment of the parallel economy. These markets operate in disequilibrium,search and information costs become very important.Trafficking in drugs taken as case, to explore both theoretically and empirically. The problem,...

We analyze bargaining mechanisms for allocating resources in atomless econo- mies. We provide results proving that it is not necessary to consider the forma- tion of all coalitions in order to obtain the bargaining sets. This is shown under restrictions of different nature, triggering different...

We introduce a class of differentiable, strictly increasing, strictly concave utility functions exhibiting an explicit demand of a good which may have Giffen behavior. We provide a necessary and sufficient condition (bases on prices and consumers’ preferences and income) under which this good...

Integrated assessment models lack a microeconomic foundation in modelling environmental damages to the economy. To overcome this, damage coefficients are incorporated in standard microeconomic models. Firms and consumers take both damages and prices as given. Demand, supply, profit and...

This paper presents a nonparametric model of interdependent preferences, where an individual’s consumption may be an externality on the preferences of other consumers. We assume that individual price consumption data is observed for all consumers and prove that the general model imposes few...

We give a notion of bargaining set for finite economies and show its coincidence with the set of Walrasian allocations. Moreover, we also show that justified objections equate with Walrasian objections. Our bargaining-Walras equivalence provides a discrete approach to the characterization of...

We introduce a new notion of bargaining set for finite economies and show a convergence result.
