    Before Kahneman and Tversky showed how behavioural economics could bring psychology and economics into a unified framework, in the 1950s a social psychologist, Sidney Siegel, entered the realm of economics and laid the foundation of experimental economics. This paper gives an assessment of Siegel‟s overall contribution and claims that Siegel was not only a pioneer of experimental economics but also of behavioural economics. Had his view on the integration of psychology and economics been more promptly received, it might have triggered a different and more successfully path to the injection of greater realism in economics. When Siegel died, his approach to integrate psychology and economics lost its main advocate. Although his legacy was paramount in the work of the Nobel Prize Vernon Smith, Siegel endorsed a quite different approach to how make interdisciplinary research effective

    Paradoxes versus formalism. Evidence from the early years of game theory and experimental economics

    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 economists because their applications challenged some basic hypotheses of mainstream economics, their subsequent acceptance was the result of the corroboration of those same hypotheses. However, the recent emergence of some paradoxes has finally revealed that the effectiveness of game theory and experimental techniques in economics is improved when descriptively implausible and normatively unsatisfactory assumptions such as the centrality of individual maximization in decision theory and the definition of rationality as consistency in preferences are revised
