Portfolio choice in high dimension
Webnumerically. First, the choice variable for the agents is the joint distribu-tion of states and controls, which is typically very high-dimensional. As shown in Jung, Kim, Matejka and Sims (2015) and Saint-Paul (2011), the optimal distribution is … Webwhere t= ( 1; ; pt)0is a p-dimensional drift process at time t, is a p p (spot) covolatility matrix at time t, and B tis a p-dimensional standard Brownian motion. A portfolio is constructed based on X t with weight w T which satis es w0 T 1 = 1 at time T and a holding period ˝, where 1 is a p-dimensional vector with all elements being 1.
