Traditional static asset pricing models, such as the CAPM, often fall short in capturing the dynamic nature of real-world investment decisions. These models typically rely on one-period frameworks, neglecting the iterative process of portfolio adjustment in response to evolving market conditions and new information. To address this limitation, a more dynamic approach is necessary to accurately model investor behavior and portfolio optimization strategies. To address this issue, it is essential to develop a multiperiod model that yields a new asset pricing formula. One such model is the Consumption-based CAPM (CCAPM), an intertemporal general equilibrium asset pricing model where investors make optimal decisions recursively.

摘要

Traditional static asset pricing models, such as the CAPM, often fall short in capturing the dynamic nature of real-world investment decisions. These models typically rely on one-period frameworks, neglecting the iterative process of portfolio adjustment in response to evolving market conditions and new information. To address this limitation, a more dynamic approach is necessary to accurately model investor behavior and portfolio optimization strategies. To address this issue, it is essential to develop a multiperiod model that yields a new asset pricing formula. One such model is the Consumption-based CAPM (CCAPM), an intertemporal general equilibrium asset pricing model where investors make optimal decisions recursively.
