Macroeconomics From the Bottom Up

Ist der Markt für ökonomische Ideen ein perfekt funktionierender Selektionsmechanismus? Heinz Kurzs Antwort auf diese Frage ist nein und somit leitet er den Rekurs auf Klassiker des Ökonomischen Denkens ein. Zunächst stellt er Charakteristika des klassischen und neoklassischen Denkens vor und vergleicht deren Grundannahmen. In Abgrenzung zur Klassik problematisiert Kurz Grundannahmen der Neoklassik, u.a. an partiellen Gleichgewichten. Im zweiten Teil des Vortrages erläutert Kurz den surplustheoretischen Ansatz der Klassik.

L'article de Carmen Guy présente les textes pionniers de l'analyse économique des crises. L'autrice montre que l’étude des crises économiques a nécessité dès le début une approche interdisciplinaire, intégrant dans un premier temps l’histoire et la statistique et ensuite la sociologie.

The definition of a chi-square distribution is given. Chi-square is defined as the sum of random normally distributed variables (mean=0, variance=s.d.=1). The number of added squared variables is equal to the degrees of freedom. With more degrees of freedom the probability of larger chi-square values is increased.

The principle of effective demand, and the claim of its validity for a monetary production economy in the short and in the long run, is the core of heterodox macroeconomics, as currently found in all the different strands of post-Keynesian economics (Fundamentalists, Kaleckians, Sraffians, Kaldorians, Institutionalists) and also in some strands of neo-Marxian economics, particularly in the monopoly capitalism and underconsumptionist school In this contribution, we will therefore outline the foundations of the principle of effective demand and its relationship with the respective notion of a capitalist or a monetary production economy in the works of Marx, Kalecki and Keynes. Then we will deal with heterodox short-run macroeconomics and it will provide a simple short-run model which is built on the principle of effective demand, as well as on distribution conflict between different social groups (or classes): rentiers, managers and workers. Finally, we will move to the long run and we will review the integration of the principle of effective demand into heterodox/post-Keynesian approaches towards distribution and growth.
