Asset Pricing with and without Garbage: The Overlooked Triple-Hypothesis Problem

Stefanos Delikouras and George Korniotis

No 16958, CEPR Discussion Papers from Centre for Economic Policy Research

Abstract: Testing consumption-based asset pricing models is a triple hypothesis, which requires selecting the consumption data and examining the assumptions for investor preferences and consumption dynamics. We formalize the triple-hypothesis problem within a GMM framework that relaxes the CRRA assumption, jointly estimates consumption dynamics with Euler equations, and includes the risk-free rate variance as a target moment. We find that consumption measures proposed as alternatives to the BEA consumption (e.g., garbage) do not address the shortcomings of the canonical CRRA model with i.i.d. consumption growth. Instead, a model with BEA consumption, Epstein-Zin preferences, and non-i.i.d. consumption dynamics performs equally well.
