We introduce a method that relies exclusively on Monte Carlo simulation in order to compute optimal portfolios. Our method is completely general and only requires complete markets and knowledge of the dynamics of the security processes. It is precise and easy to implement. It can be applied...

This paper analyzes the response of the Term Structure of discount rates to the changes in the Federal Funds Target Rate. It also suggests a method of hedging fixed income portfolio's risk to the unexpected changes in monetary policy. We use two alternative widely used models of term structure...

This paper examines the impact of Olympic Sponsorship announcements on stock returns for sponsors of the ten Olympic Summer Games held between 1984 and 2020. The paper finds that sponsorship announcements are associated with an average 0.44% impact on returns on the announcement day. This...

This paper is concerned with nonlinear filtering of the coefficients in asset price models with stochastic volatility. More specifically, we assume that the asset price process S=(St)t≥0 is given by dSt=m(θt)St dt+v(θt)St dBt, where B=(Bt)t≥0 is a Brownian motion, v is a positive...

In the framework of continuous-time, Itô processes models for financial markets, we study the problem of maximizing the probability of an agent's wealth at time T being no less than the value C of a contingent claim with expiration time T. The solution to the problem has been known in the...

This paper presents an equilibrium model in a pure exchange economywhen investors have three possible sources of heterogeneity. Investorsmay differ in their beliefs, in their level of risk aversion andin their time preference rate. We study the impact of investors heterogeneityon equilibrium...

We provide a representation for the nonmyopic optimal portfolio of an agentconsuming only at the terminal horizon when the single state variable follows ageneral diusion process and the market consists of one risky asset and a risk-freeasset. The key term of our representation is a new object...

We study survival, price impact and portfolio impact in heterogeneouseconomies. We show that, under the equilibrium risk-neutral measure,long-run price impact is in fact equivalent to survival, whereas longrunportfolio impact is equivalent to survival under an agent-specic,wealth-forward...
