O’Donnell’s attack on the ergodic/nonergodic approach to Keynes’s uncertainty concept is erroneous. Keynes’s produced a general theory by imposing fewer restrictive axioms than classical theory. Keynes’s explicitly attacked the classical theory’s axiom that an actuarially certain knowledge regarding the future is available to decision makers; thus Keynes’s analysis rejects the ergodic hypothesi...

On a topic like the environment, communication among scholars from different disciplines in the natural and social sciences is both important and difficult, but such communication has been far from perfect. Economists themselves may have contributed to some rather fundamental misunderstandings about how economists think about the environment, perhaps through our enthusiasm for market solutions,...

The Knowledge Engineering Review is an outstanding journal in Computer Science. The guest editors and contributors to this Special Issue are economists. Why is this so? In recent years there has been a growing dialogue between economists and computer scientists, to our mutual benefit. The Special Issue is devoted to nine papers in which economists survey aspects of the field of agent-based comp...

The purpose of this article is to analyse the way economists interested in social and economic evolution cite, mention or refer to Darwin. We focus on the attitude of economists towards Darwin’s theory of social evolution – an issue he considered as central to his theory. We show that economists refer to and mention Darwin as a biologist and neglect or ignore his theory of social and cultural e...

Quantum game theory is an important development in quantum computation, and has implications both for classical economic game theory and for quantum mechanics. Unfortunately, the quantum mechanical and quantum computational knowledge assumed in the literature presents a serious communication barrier for most economists. In the other direction, quantum game theory does not always seem to be cogn...
