We study simple majority rule from a perspective of coalitional decision makings. Four attrative properties each linking decisions by a group to decisions by its various coalitions are introduced, and are used for characterizing simple majority rule. Our characterization result provides an...

In decision-making involving multiple criteria or attributes, the attributes are often divided into core and non-core attributes. A dominance principle is formulated in terms of core attributes, and this principle is applied whenever it is applicable. If, however, the dominance principle defined...

When a society's overall deprivation or living standard is assessed in a multi-attribute framework, the following procedure is often used. First, for each attribute, a summary index is constructed to reflect a society's performance in relation to this attribute. Then, an indicator of the overall...

This paper examines the literature in welfare economics with a focus on individual rights and freedom, two important components in welfare economics. The paper discusses conceptions of rights and freedom intuitively and presents a critical examination of the existing literature

We study approval voting in a setting with a fixed profile of individuals choices and variable societies. Four properties each linking choices made by a group of individuals to choices by its various subgroups are introduced, and are used for characterizing approval voting

This chapter discusses freedom and its value. We focus on the conceptual structure of freedom and the value of freedom. We also discuss several issues relating to the measurement of freedom and the value of freedom, and the notion of opportunity sets, a key component of the conceptual structure...

This paper discusses issues of axiomatic bargaining problems over opportunity assignments. The fair arbitrator uses the principle of "equal opportunity" for all players to make the recommendation on resource allocations. A framework in such a context is developed and several classical solutions...

A society is composed of different socio-economic groups. At a given time, individuals in the society can be classified into different such groups. With the change of time, individuals can move across different groups. Social mobility is viewed as an aggregation of such individual movements...

In this paper, I make a connection between a Kantian equilibrium for a game as introduced in Roemer (2010) and a conjectural variation equilibrium as discussed in the literature on oligopolistic competition. I show that, for the class of games studied by Roemer (2010), any Kantian equilibrium is...

The standard theory of rational choice in economics considers an agent's choices to be rational if and only if the agent makes her choices in different choice situations on the basis of a fixed preference ordering defined over the set of all possible options. This implies that a rational agent's...
