Complexity Science: 11 Complexity Economics

Have you ever wondered why it is so difficult to follow through on new year’s resolutions, such as to exercise more or to start saving more money towards retirement? The agent that most traditional economic models are based on would not struggle to keep up these resolutions. These agents are referred to as homo economicus.

In this lecture, Konstantinos Katsikopoulos presents the concept of bounded rationality and contrasts two - as he calls it - cultures of research and analysis within Behavioral Economics: an "idealistic" and a "pragmatic" approach. Thereby, Katsikopoulos discusses amongst others their different assumptions on decision making (utility optimization vs. achievement of a satisfactory outcome), the psychological process as well as the epistemic aim and implications on policy recommendations (nudging vs. education).

How countries achieve long-term GDP growth is up there with the most important topics in economics. As Nobel Laureate Robert Lucas put it “the consequences for human welfare involved in questions like these are simply staggering: once one starts to think about them, it is hard to think about anything else.” Ricardo Hausmann et al take a refreshing approach to this question in their Atlas of Economic Complexity. They argue a country’s growth depends on the complexity of its economy: it must have a diverse economy which produces a wide variety of products, including ones that cannot be produced much elsewhere. The Atlas goes into detail on exactly what complexity means, how it fits the data, and what this implies for development. Below I will offer a summary of their arguments, including some cool data visualisations.
