The Basics of Commons
In this short Video Silke Helfrich discusses the basics of commons. It’s an introduction into the essence of commons from a perspective stemming from outside the economic discipline that focuses on social practice. Her perception challenges the economic mainstream’s perception of common goods and goes beyond a purely materialistic conceptualisation of commons.

What is Feminist Economics & what does it have to do with studying the climate crisis?
This video explains what the term 'Feminist Economics' describes and goes into detail on how feminist economists use methodology differently, why they advocate for diversity in research and how to look into preconditions for the functioning of our economies. It, additionally, highlights the link between feminist economics and the study of climate change.

Econometrics // Lecture 3: OLS and Goodness-Of-Fit (R-Squared)
First some properties about the Sum of squared residuals and the linear regression function are restated. In particular three properties that an ideal fitted regression line must fulfill are discussed. Then, the R squared is defined using the measures of the Sum of squared residuals, the total sum of squares and the sum of explained squares.
