Physics of socio-economic systems

Throughout this course we shall explore how socio-economic systems can be studied from a physicist’s perspective. Building upon stylised facts revealed by empirical data, we shall focus our approach on agent-based modelling (ABM) to account for collective effects resulting from interaction, heterogeneity, irrationality, feedback and learning to name a few. In particular, we shall pay attention to keeping a good balance between mathematical analysis and intuition of the phenomena at hand; we will often use numerical simulation to go beyond to scope of analytically tractable models.

Phenomenology & modelling of financial markets

This course presents the approach adopted by physicists to analyze and model financial markets. Our results shall always rely on real financial data. Rather than sticking to a rigorous formalism, we seek primarily to develop one's intuition on the "mechanics" of markets, toy models, orders of magnitude, and open problems.

1. Empirical time series
