This paper discusses the following two hypotheses. The first one is based on the epistemological proposal which we have named the principle of discontinuity. It asserts that certain developments in the history of economic thought involve theoretical breaks which can only be fully explained by...

Keynes was adamant that the assumption of homogeneous output and capital in macroeconomic theory is inadmissable. His aggregate supply or Z function is a generalisation of Marshall's ordinary supply function to take account of heterogeneous output, and is an essential element of the principle of...

The thesis of this paper is that Keynes wrote A Treatise on Probability contrasting his view to the frequentist theory, systematised by John Venn, which denied to probability any sort of utility in decision theory. Keynes's problem was of finding an alternative theory to be utilised as a guide...

The interplay of epistemic and empiric conditions of human behaviour plays a crucial role in economic causality but it is not satisfactorily analysed by the existing approaches to economic causality, including the most influential of them: Granger causality. In order to find a more satisfactory...

In 1987, Greenwald and Stiglitz accused Keynes's summary of the "General Theory" in chapter 18 of relying upon “neoclassical and Marshallian tools.” A number of contributions have on the contrary emphasized the methodological importance of this chapter, which this paper revisits in the light...

Was the Keynesian message alive during the second half of the XXth Century, or was it betrayed by his followers? This article in the fields of the history of economic thought and methodology contrasts the Scientific Research Programmes (SRPs), a Lakatosian concept, of Keynes in The General...

Unlike standard accounts, recent research in the history of macroeconomics has given increasing attention to the Old Keynesians’ criticisms of the New Classical Economics. In this paper, I address the case of Edmond Malinvaud, who began opposing the latter from the early 1980s and did so...

This paper discusses Joan Robinson’s remarks on the importance of historical time in economic analysis. On the one hand, Joan Robinson expressed skepticism with equilibrium analysis as such, arguing that as soon as economists take into account the uncertainty of expectations, history needs to...

This paper re-assesses Ramsey’s influence on Keynes. It is argued that the Standard View has restricted attention to the implications for probability theory of Ramsey’s criticisms of Keynes’s concepts of logical probability-relations and non-numerical probabilities. Building on the work of...

Keynes’ ‘fallacy of composition’ and, later, the ‘Santa Fe perspective’ have shown that the economy may be defined as a “complex adaptive system”, since it is not something given but results from constantly developing interactions among heterogeneous individuals. Endorsing the...
