Traditional finance explains individual investors' behavior and financial decision-making based on economic incentives and rationality. Modern finance, however, takes a holistic view and searches for not only economic but also biological, psychological, and social factors that shape...

In standard financial model which is proposed by Markuitz, the basis of financial activity is on logical act of investors. With establishment of a branch named behavioral finance which is based on the works of Kahneman and Tuerski, the role of psychology of investors and the results of...

We determine a simple dynamic benchmark for asset allocation by solving an optimal stochastic control problem for outperforming the traditional constant proportion benchmark. An objective function based on a time averaged quadratic deviation from an elevated benchmark is proposed. We argue that...

This paper considers a general class of stochastic dynamic choice models with discrete and continuous decision variables. This class contains a variety of models that are useful for modeling intertemporal household decisions under risk. Our examples are drawn from the field of development...

This paper studies optimal saving and investment behaviour of a household that can either invest in a riskless or a risky saving technology when risk results from a Poisson process. The focus is on behaviour of households in a general equilibrium setup. Poisson processes are introduced since...

In this paper, we study the problem of option portfolio design under the Markowitz mean-variance framework. We extend the common practice of a pure-stock portfolio and include options in the design. The options returns are modeled statistically with first- and second-order moments, enriching the...

I investigate a dynamic life-cycle strategic asset allocation and consumption problem under model uncertainty, where both inflation rate and income growth rate are assumed to be estimated with errors. I present a feasible boundary for the uncertainty aversion parameter, which measures the...

In this paper, a link between a time-consistent and a pre-commitment investment strategy is established. We define an implied investment target, which is implicitly contained in a time-consistent strategy at a given time step and wealth level. By imposing the implied investment target at the...

We extend the framework of trading strategies of Gatheral [2010] from single stocks to a pair of stocks. Our trading strategy with the executions of two round-trip trades can be described by the trading rates of the paired stocks and the ratio of their trading periods. By minimizing the...
