This paper analyzes the expected life-time utility and the hedging demands in an exchange only, representative agent general equilibrium under incomplete information. We derive an expression for the investor's expected life-time utility, and analyze his hedging demands for intertemporal changes...

This paper analyzes the expected life-time utility and the hedging demands in an exchange only, representative agent general equilibrium under incomplete information. We derive an expression for the investor’s expected life-time utility, and analyze his hedging demands for intertemporal changes...

Three types of agents acting on different information sets are considered: fully informed agents, insiders, and outsiders. Differences in information quality are shown to affect the properties of their optimal portfolios. For an outsider, the share of wealth invested in the stock is decreasing...

This paper considers the optimal hedge ratio problem under estimation risk. Due to incomplete information, the decision-maker evaluates the opportunity cost of hedging using exchange-traded funds or notes (ETF/Ns). Using a back-testing procedure over the last five years and 13 different hedging...

Robust Portfolio Modeling (RPM) Theory is a decision-support methodology to analyze multiple criteria project portfolio problems. Liesioa et al [17] generalized RPM based on the appendix information, and studied the characteristics of non-inferior solution sets, but they did not compare the...

I study the effects of risk and ambiguity (Knightian uncertainty) on optimal portfolios and equilibrium asset prices when investors receive information that is difficult to link to fundamentals. I show that the desire of investors to hedge ambiguity leads to portfolio inertia and excess...

The essential incentives for investment portfolio managers are pursing relative outstanding portfolio performance among their peers in order to be rewarded by the fractions of the fund inflows. This competition for fund inflows becomes dynamic games among money managers. This paper accordingly...

We consider an investor faced with the utility maximization problem in which the risky asset price process has pure-jump dynamics affected by an unobservable continuous-time finite-state Markov chain, the intensity of which can also be controlled by actions of the investor. Using the classical...

The optimal retirement decision is essentially an optimal stopping problem when retirement is irreversible. We investigate the optimal consumption, investment and retirement problem when the growth rate is unobservable and is estimated by filtering from historical stock prices. To ensure both...
