L'essor de l'économie comportementale, des RCT (randomized controlled trials) et de l'histoire économique quantitative est souvent considérée comme un retour des sciences économiques à des faits et causalités rigoureusement établis, dépassant les débats théoriques. Ce "retour au concret" en est-il vraiment un ?

This course introduces students to the relevance of gender relations in economics as a discipline and in economic processes and outcomes. The course covers three main components of gender in economics and the economy: (1) the gendered nature of the construction and reproduction of economic theory and thought; (2) the relevance and role of gender in economic decision-making; and (3) differences in economic outcomes based on gender. We wil touch on the relevance of gender and gender relations in at least each of the following topics: economic theory; the history of economic thought; human capital accumulation; labor market discrimination; macroeconomic policy, including gender budgeting; household economics; basic econometrics; and economic crises.

Jeden Freitag streiken weltweit Schüler/innen für unsere Zukunft. Sie fordern radikale Maßnahmen für die Einhaltung des Pariser Klimaabkommens ein. In diesem Seminar werden wir uns aus der Perspektive der ökologischen Ökonomie mit ihrer Kritik auseinandersetzen. Im Fokus stehen dabei Ansätze einer Postwachstumsökonomie.

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.
