This paper tracks economists' rising, yet elusive and unstable interest in collective decision mechanism after World War II. We replace their examination of voting procedures and social welfare functions in the 1940s and 1950s in the context of their growing involvement with policy-making....

The death of welfare economics has been declared several times. One of the reasons cited for these plural obituaries is that Kenneth Arrow's impossibility theorem, as set out in his path-breaking Social Choice and Individual Values in 1951, has shown that the social welfare function - one of the...

Environments with semi-ordered preferences, which may exhibit indifference intransitivity, are known to allow just-noticeable differences in preference intensity to serve as interpersonally comparable units of utility. I prove two impossibility theorems for social choice in such environments....

Amartya Sen’s impossibility of a Paretian liberal underscores the trade-off between two widely applied social principles—liberalism and Pareto-optimality: “If someone does have certain liberal values, then he [or she] may have to eschew his [or her] adherence to Pareto optimality” (Sen...

Democratic societies have been increasingly confronted with extreme, knife-edge election outcomes that affect everybody's lives and contribute to social instability. Even if political compromises based on social conventions as equity or economic arguments as efficiency are available, polarized...

Written for the Chapman Law Review Symposium on “What Can Law & Economics Teach Us About the Corporate Social Responsibility Debate?,” this Article applies the lessons of public choice theory to examine corporate social responsibility. The Article adopts a broad definition of corporate...

Historians of economic thought are paying greater attention to issues of social ontology (that is, to the assumptions that economists make about the nature of social reality). In this paper, we contribute to this burgeoning literature by exploring the hitherto neglected way in which James...

The various subdisciplines within the emerging ‘new institutionalism’ in economics all draw special attention to the legal-political constraints within which economic and political agents choose. By changing the name of his research programme to Constitutional Political Economy Buchanan...

The existence of a Paretian and finitely anonymous ordering in the set of infinite utility streams implies the existence of a non-Ramsey set (a nonconstructive object whose existence requires the axiom of choice). Therefore, each Paretian and finitely anonymous quasi-ordering either is...
