Syllabus of "Financial Economics 2.0: bubbles, instability and speculation"
After a brief refresh of the theory of choices under uncertainty, securities markets, and the notion of arbitrage, the course introduces to the tools and methods of inter-temporal equilibrium models with heterogeneous agents. On the economic side, the focus is on the role of heterogeneous beliefs and preferences on asset pricing. Both standard general equilibrium models and evolutionary models are presented. On the mathematical side, classical results on local and global analysis of stochastic processes are reviewed. Inside this framework, the course proceeds to analyze three interrelated aspects: the occurrence of rational bubbles, the effect and persistence of speculation, and optimal portfolio choice in an evolutionary framework.
