ICAPM

From Wikipedia, the free encyclopedia

The Intertemporal Capital Asset Pricing Model, or ICAPM, is a linear factor model with wealth and state variable that forecast changes in the distribution of future returns or income.

The main difference between ICAPM and standard CAPM is additing state variables that acknowledge the fact that investors hedge against shortfalls in consumption or against changes in the future investment opportunity set.
