We study an intertemporal consumption and portfolio choice problem under Knightian uncertainty in which agent's preferences exhibit local intertemporal substitution. We also allow for market frictions in the sense that the pricing functional is nonlinear. We prove existence and uniqueness of the...

Frank H. Knight's classic, Risk, Uncertainty and Profit, became a standard textbook and reference for students at the University of Chicago, the London School of Economics and Political Science, and elsewhere from the 1930s until at least the 1950s. Knight never published new or revised editions...

We derive a class of utility functions that are equivalent with respect to a well-defined functional form. We apply a general view of constant relative risk aversion to investigate on different equivalence relations. Then we compare our results with standard applications in economics and finance.

This paper characterizes optimal consumption and investment policies for investors with asset return predictability, stochastic labor income and endogenously-determined retirement. We find that the ratio of total wealth-to-labor income (normalized wealth) is the primary determinant of the...

This paper explores optimal consumption and portfolio decisions in the presence of risky house prices. We assume that changes in real interest rates and future rents directly impact house prices. A novel aspect of our model is that rent inflation rates and consumption inflation rates are...
