In this keynote lecture during the conference „The Spectre of Stagnation? Europe in the World Economy“, Till van Treek presents research on how changes in income distribution lead to macroeconomic instability and crisis, focusing on currents accounts. Treek presents the relative income hypothesis in contrast to other mainstream and Post-Keynesian explanations. The relative income hypothesis proposes that aggregate demand increases and savings decrease with rising personal income inequality due to upward looking status comparison – but effects depend on the quantile where income inequality increases. Treek points to the importance of accounting for both income and functional income distribution and underlines his arguments with data comparing different pattern in Germany and the U.S.

In this short video behavioural economist, Dan Aerily talks about how our cognitive illusions will trick us into believing something that is otherwise deemed irrational by the homo economicus. It raises and probes into some very interesting questions that defy the neoclassical rational behaviour.

Thomas Boraud, neurobiologiste, directeur de recherche au CNRS et à l’Institut des maladies neurodégénératives, CNRS-Université de Bordeaux nous expose l'antinomie entre l’Homme comme un animal doué de raisonnement rationnel et sa psychologie au quotidien. Il introduit sa présentation par des arguments provenant de la biologie et de la théorie de l'évolution pour expliquer en quel sens le concept d'homo œconomicus est dépassé et doit être revu au jour d'aujourd'hui. Il expose les fondements du processus de prise de décision (biais cognitif, capacité cognitive limitée...) pour décrire la part d’aléatoire qui est présente dans ces processus. On y apprend que notre appréhension du réel est largement modelée par nos comportements, eux-mêmes contraints par les circonstances de notre environnement.

This Perspective argues that ergodicity — a foundational concept in equilibrium statistical physics — is wrongly assumed in much of the quantitative economics literature. By evaluating the extent to which dynamical problems can be replaced by probabilistic ones, many economics puzzles become resolvable in a natural and empirically testable fashion.

Orthodox economics operates within a hypothesized world of perfect competition in which perfect consumers and firms act to bring about supposedly optimal outcomes. The discrepancies between this model and the reality it claims to address are then attributed to particular imperfections in reality itself.
