The portfolio allocation paradox: An investigation into the nature of a very strong but puzzling relationship
Myths and meanings of voting power : comments on a symposium
These are comments on the Symposium 'Power Indices and the European Union' in the July 1999 issue of this Journal. We point out several common inter-connected confusions and errors concerning the meaning of voting power. We stress the vital distinction between two different intuitive notions of voting power. We emphasize the need for a unified approach to the study of a priori and actual voting power. We show that the family of 'strategic' measures proposed by some of the participants in the Symposium are a natural generalization of the Banzhaf measure

Models and reality: the curious case of the absent abstention
We discuss two inter-related puzzling features of the literature on a priori voting power. First, the mathematical model used in virtually all this literature does not recognize abstention as an option distinct from both a 'yes' and a 'no' vote. Second, real-life decision rules of voting bodies---in particular the US legislature and the UN Security Council---are misrepresented as though they did not allow abstention as a tertium quid. We suggest that these misrepresentations may be examples of what philosophers of science call 'theory-laden observation'
