Abstract

The research project aims to conduct a deeper investigation of the interconnections between the financial system and the real economy, by developing, for the first time in the literature, a model that captures the insights of the theory of reflexivity about the influence of stock prices on fundamentals.

The motivation of the research project resides in the belief that the standard approach, based on the representative agent paradigm, is misguided, and that a fundamentally different approach, based on statistical physics, is necessary to analyze the interconnections between the financial system and the real economy.

The real economy and the financial markets are modeled as complex systems of interacting heterogeneous agents using tools drawn from statistical physics, mathematics, biology, economics and other social sciences. More specifically, we employ the stochastic dynamic aggregation techniques. Also the notion of equilibrium needs to be reconsidered.

The final objective of the research project consists in modeling the interconnections between the stock price and the fundamentals using the following the transmission mechanism: the stock prices affect the mood (i.e. confidence) of the economic agents, the mood of economic agents affect the aggregate level of consumption and investment, and, therefore, the aggregate level of output and the level of profit per share, which is the fundamental variable that influences the stock price. The model that will be developed in this research project will have a major impact on theoretical level and will have direct policy implications, providing decision-makers with refined instruments for analyzing the interconnections between fundamentals, the confidence of economic agents and the stock market.
