Abstract: This paper offers a unified theory, which maps financial markets into a two dimension Banach space by quantizing the price fluctuation and trading volume of financial assets. In this space, we develop a new portfolio theory and capital asset pricing model. Then, we analyze normal and...

This paper introduces agent heterogeneity, liquidity, and endogenous default to a DSGE framework. Our model allows for a comprehensive assessment of regulatory and monetary policy, as well as welfare analysis in the different sectors of the economy. Due to liquidity and endogenous default, the...
