Value at Risk (VaR) has emerged in recent years as a standard tool to measure and control the risk of trading portfolios.Yet,existing theoretical analyses of the optimal behavior of a trader subject to VaR limits have produced a negative view of VaR as a risk-control tool. In particular,VaR...

We analyze the problem of real optimal asset allocation for a pension fund maximising the expected CRRA utility of its real disposable wealth. The financial horizon of the analysis coincides with the random death time of a representative subscriber. We consider a very general setting where there...

Standard tests designed to identify mutual funds with non-zero alphas are problematic, in that they do not adequately account for the presence of lucky funds. Lucky funds have significant estimated alphas, while their true alphas are equal to zero. To address this issue, this paper quantifies...

In a financial market with one riskless asset and n risky assets following geometric Brownian motions, we solve the problem of a pension fund maximizing the expected CRRA utility of its terminal wealth. By considering a stochastic death time for a subscriber, we solve a unique problem for both...

Empirical evidence shows that observed macroeconomic fundamentals have little explanatory power for nominal exchange rates (the exchange rate determination puzzle). On the other hand, the recent \microstructure approach to exchange rates" has shown that most exchange rate volatility at short to...

The informational content of changing risk for dynmaic asset allocation is analyzed in order to investigate its importance in determining expected index returns. We consider a class of optimal dynamic strategies taking into account both changing risk and expected returns that vary accordingly to...

Individual and collective security are among the gauges of civilization, and at the same time they constitute necessary conditions for its progress. Their systematic pursuit is relatively recent among nations: prompted by the dreadful lessons of the 20th century, they took their present shape...

This paper introduces state dependent utility into the standard Mehra and Prescott (1985) economy by allowing the representative agent’s coefficient of relative risk aversion to vary with the underlying economy’s growth rate. Existence of equilibrium is proved and its asymptotic properties...

We use the Adjusted Present Value (APV) method with Monte Carlo simulations for real estate valuation purposes. Monte Carlo simulations make it possible to incorporate the uncertainty of valuation parameters, in particular of future cash flows, of discount rates and of terminal values. We use...

The allocation to real estate by institutional investors has increased in recent years and as a result the gap between suggested and actual allocations has narrowed. The increased inflow of capital to the real estate market is suggested to be a function of two factors: An increased focus on...
