On the concavity of the consumption function

Web(1996) show the concavity of consumption functions in nite horizon problems, which implies asymptotic linearity. However, under certain regularity assump-tions,Toda(2024) shows that HARA is necessary for the concavity of con-sumption functions, implying that establishing asymptotic linearity based on concavity is possible only in very special ... Web1 de mai. de 2024 · If the consumption function in Lemma 1 is concave for arbitrary distribution of (β, R, Y), then u exhibits constant relative risk aversion (CRRA). Conversely, if u is CRRA, then the consumption function of the consumption-saving problem (1) is concave. Proof. Let c, s be the consumption and saving functions.
