WebNOTES. 1 For the concavity of the consumption function generated by prudence, see Carroll and Kimball [4].. 2 Uncertainty in rate-of-return or labor income can be easily introduced in the model set-up, but will not alter the main implication. Indeed, since the very message of this paper is the concavity of consumption function under deterministic … Websharing function ensues in a straightforward way. Then, parametric global concavity tests are applied against global parametric alternatives. 2 Framework When modeling household consumption behaviour, collective rationnality is a reasonnable assumption to make (Chiappori, 1988; Apps and Rees, 1988; Chiappori and Ekeland, 2006).

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 ... WebWe consider an optimal investment problem to maximize expected utility of the terminal wealth, in an illiquid market with search frictions and transaction costs. In the market model, an investor’s attempt of transaction is successful only at arrival times of a Poisson process, and the investor pays proportional transaction costs when the transaction is successful. … marine watermakers pricesWebdomains for which even some linear functions (which are both concave and convex) are not continuous. 3 Concavity, Convexity, and Di erentiability. A di erentiable function is concave i it lies on or below the tangent line (or plane, for N>1) at any point. Theorem 6.
