Asset Pricing and the Propagation of Macroeconomic Shocks
This paper considers the implications of habit formation and financial frictions for the propagation of macroeconomic shocks. In a model that is capable of matching asset pricing moments, a short-lived shock that destroys a small fraction of the economy’s stock of pledgeable collateral generates a persistent recession, a stock market crash, and a flight-to-safety effect. This novel mechanism creates a tight link between the asset pricing implications of macroeconomic models and their ability to propagate and amplify the effects of macroeconomic shocks.
With Shanghai stock exchange market as a research object, this paper studies the complexity of the stock exchange market using the cellular automata theory and model. With the fractal theory as a tool, the R/S method is used to compare the real and the simulated data, which verifies the validity of the simulation. In the CA model, with different initial values and rules, we can improve the study on complexity in the stork exchange market.
