The aim of this paper is to investigate in some detail the origins of Knight’s antipositism and to assess the main influences that brought him to a change in methodological perspective after 1921. As importantly, what follows is also an attempt to increase our general understanding of the...

A choice function is a symmetric revealed core if there exists a symmetric irreflexive ‘dominance’ digraph such that choice sets consist precisely of the locally undominated outcomes of the latter. Symmetric revealed pseudocores are similarly defined by omitting the irreflexivity requirement...

Characterizations of the choice functions that select the cores or the externally stable cores induced by an underlying revealed dominance digraph are provided. Relying on such characterizations, the basic order-theoretic structure of the corresponding sets of revealed cores is also analyzed

The choice functions that are consistent with selections of VNM-stable sets of an underlying revealed dominance digraph are characterized both under VNM-perfection of the latter and in the general case.

Like land before the industrial revolution, much knowledge is being enclosed in private hands. These enclosures have become a major factor in specialization among firms and among countries: both are forced to specialize in the fields that are not restricted by the enclosures of the others. This...

This paper analyses the foundation of utilitarian ethics and theory of probability in the works of Francis Y. Edgeworth. We argue that he pursued an unitary philosophical project, the search for a common epistemological foundation for the social sciences. The common root of the disciplines is...

This paper argues that the acceptance of two recent methodological advances in economics, namely game theory and laboratory experimentation, was affected by the history dependence constraining the formalization of economics. After an early period in which the two methods were coolly received by...

Probability theory has a central role in Edgeworth’s thought; this paper examines the philosophical foundation of the theory. Starting from a frequentist position, Edgeworth introduced some innovations on the definition of primitive probabilities. He distinguished between primitive...

This paper proposes a general interpretation of Edgworth’s thought based on the recognition of a unitary philosophical project in his contributions to ethics, economics, probability and statistics. This project consists in the search for a common epistemological foundation for the social...

In biology, the laws that regulate the structuring and change of complex organisms, characterised by interlocking complementarities, are different from those that shape the evolution of simple organisms. Only the latter share mechanisms of competitive selection of the fittest analogous to those...
