Abstract games admitting stable solutions
Lahiri, Somdeb (2010-01-16)An abiding problem in choice theory has been one of characterizing those choice functions which are obtained as a result of some kind of optimization. Specifically, the endeavour has concentrated largely on finding a binary ... -
Affine cost share equilibria for economies with public goods
Lahiri, Somdeb (2010-03-26)In this paper we propose the concept of an affine cost share equilibrium and show that under natural assumptions any optimal allocation corresponds to an affine cost share equilibrium. With linear cost functions and under ... -
Algorithm for the min - max loss rule for claims problems
Lahiri, Somdeb (2010-04-08)In this paper we provide an algorithm which gives us the unique solution to the problem of minimizing the maximum loss (where loss is measured by unsatisfied demands) for a claims problem. The answer lies crucially on the ... -
Arbitration by a Bayesian statistician and bounded rationality
Lahiri, Somdeb (Indian Institute of Management Ahmedabad, 1990-01-01)In this paper we formalize the framework of an arbitration game, to accommodate a large class of situations where public decisions are implemented in a non-cooperative setting. We then present a method of computing the ... -
Arbitration games and approximate equilibria
Lahiri, Somdeb (2010-03-15)In this paper we define an arbitration game in the context of a Bayesian Collective Choice Problem and derive an approximate equilibrium for such games under conditions of 'bounded rationality'. -
Average welfare fair and egalitarian solutions for bargaining problems
Lahiri, Somdeb (2010-03-21)In this paper e present an alternative characterization of the Egalitarian Solution for bargaining problems and show that the Egalitarian solution has the property that for any agent the incremental utility from bargaining ... -
Axiomatic analysis of choosing the second best
Lahiri, Somdeb (2009-12-14)The dominant theme in decision theory has been the one where an agent chooses what is perceived to be the best outcome out of a (finite) set of outcomes. This has been the model that economic theory has traditionally ... -
Axiomatic analysis of vote aggregators
Lahiri, Somdeb (2010-01-16)In this paper a model for the aggregation of ballot profiles is considered. In this framework some new results are obtained: the characterization of oligarchic aggregators, the characterization of the plurality aggregator ... -
Axiomatic characterisation of weighted boolean vote aggregators
Lahiri, Somdeb (2010-01-18)A Federation Boolean Vote Aggregator allows a finite set of coalitions to unilaterally elect any candidate from a set containing exactly two candidates. There are several special types of Federation Boolean Vote Aggregators, ... -
Axiomatic characterisation of weighted voting operator
Lahiri, Somdeb (2010-01-18)A federation voting operator allows a finite set of coalitions to unilaterally elect any outcome. There are several special types of federation voting operators, all of which share a property: the candidates are assigned ... -
Axiomatic characterization of budget constrained Pareto efficient social choice for fair division problems
Lahiri, Somdeb (Indian Institute of Management Ahmedabad, 1998-11-01)In this paper, we axiomatically characterize the social choice correspondence, which picks for each economy, the set of equal income budget constrained Pareto efficient allocations. We are able to characterize this social ... -
Axiomatic characterization of indirect utility and lexicographic extensions
Lahiri, Somdeb (2010-01-16)The general problem we are interested in this paper is of the following variety: We are given a finite universal set and a linear ordering on it. What is the minimal axiomatic characterization of particular extension of ... -
Axiomatic characterization of some extensions
Lahiri, Somdeb (2009-12-12)The general problem we are interested in this paper is of the following variety. We are given a finite universal set and a linear ordering on it. What is the minimal axiomatic characterization of a particular extension of ... -
Axiomatic characterization of the cao choice function for multiattribute choice problems
Lahiri, Somdeb (2009-12-12)In this paper we provide an axiomatic characterization of a choice function due to Cao (1981) multiattribute choice problems. -
Axiomatic characterization of the constrained equal awards solution for rationing problems
Lahiri, Somdeb (2010-03-31)In this paper we propose two different, yet related axiomatic characterizations of the Constrained Equal Award Solution for rationing problems. The solution itself and its implications are studied in the context of an item ... -
Axiomatic characterization of the equal income market equilibrium choice correspondence in non convex economies
Lahiri, Somdeb (2010-04-01)A property of allocation rules (in problems involving fair division of infinitely divisible goods amongst a finite number of agents) that has received considerable attention in recent literature is consistency. The property ... -
An axiomatic characterization of the equal loss choice function for multiattribute choice problems
Lahiri, Somdeb (2010-03-27)In this paper we provide an axiomatic characterization of the equal loss choice function for multiattribute choice problem. -
Axiomatic characterization of the lexicographic utilitarian collective utility function
Lahiri, Somdeb (2010-03-29)In this paper we axiomatically characterize the family of lexicographic utilitarian collective utility functions. As a by-product we obtain the utilitarian collective utility function by imposing a shift anonymity condition. ... -
An Axiomatic characterization of the value function for bimatrix games
Lahiri, Somdeb (Indian Institute of Management Ahmedabad, 1990-10-01)In this paper we obtain an axiomatic characterization of the value function for the class of all bi matrix games satisfying the equivalency and efficiency properties. -
Axiomatic characterizations of solutions for rationing problems
Lahiri, Somdeb (2010-07-27)Situations abound in the real world, where aggregate demand for a commodity exceeds aggregate supply. When such situations of excess demand occur, what is required is some kind of rationing. The literature on rationing ...
