This paper argues that Ellsberg’s and Shackle’s frameworks for discussing the limits of the (subjective) probabilistic approach to decision theory are not as different as they may appear. To stress the common elements in their theories Keynes’s Treatise on Probability provides an essential...

G.L.S Shackle’s rejection of the probability tradition stemming from Knight's definition of uncertainty was a crucial episode in the development of modern decision theory. A set of methodological statements characterizing Shackle’s stance, abandoned for long, especially after Savage’s...

After the publication of Keynes' "General Theory," economics was frequently described as schizophrenia: (neo-) classical at the micro-level, but Keynesian at the macro-level. In actuality, Keynes' revolution was, to a substantial part, based on the behavioral micro-foundations of the world we...

Keynes' General Theory (GT) ist in zweierlei Hinsicht umfassender als das (neo-) klassische Modell: (1) sie schließt das Vollbeschäftigungsgleichgewicht als Sonderfall ein und (2) sie basiert auf realistischem mikroökonomischem Verhalten, dessen sozial isolierter, den Eigennutz maximierender...

Shackle was one of the representative critics of probability calculus. His alternative decision theory was mathematically reformalized by Katzner till 1990s. Following the Katzner's reformalized framework, this paper presents a new interpretation of Shacklean theory by focusing on the common...

In the history of economic thought, Shackle was one of the representative critics about probability based economic theory. Specifically, he constructed his own concept of subjective uncertainty called potential surprise to replace probability. In 1980s, the potential surprise is axiomatized by...

A by-product of the recent financial crisis has been the renewed interest in Keynes's works. Both in the press and in scientific journals, a crowd of commentators has emphasised the need to scrutinise the General Theory in order to gain a better understanding of the actual macro-dynamics of the...

The recent financial crisis has renewed the interest in Keynes's thought and his analysis of the role played by individual agents in financial markets. George Akerlof and Robert Shiller, in particular, have drawn on the growing interest in behavioural interpretations of financial markets to hold...
