Our analysis takes the perspective of an equity fund manager who seeks a potential safe haven asset to protect her portfolio during market downturns. We employ a regime-switching framework, within which we separate common and idiosyncratic shocks, to assess the suitability of gold, 10-year and...

We study the impact of financial contagion on the dynamic asset allocation problem of a CRRA investor facing an incomplete market with two risky assets. We apply a Markov chain regime-switching framework with state-dependent jump intensities, diffusion volatilities and diffusion correlations....

Systemic crises can largely affect asset allocations due to the rapid deterioration of the risk-return trade-off. We investigate the effects of systemic crises, interpreted as global simultaneous shocks to financial markets, by introducing an investor adopting a crisis ignorant or crisis...

This paper is concerned with a finite-horizon optimal investment and consumption problem in continuous-time regime-switching models. The market consists of one bond and n ≥ 1 correlated stocks. An investor distributes his/her wealth among these assets and consumes at a non-negative rate. The...

In this paper we will check the homogeneity/heterogeneity of Levy processes using some non-parametric homogeneity tests. First we create two samples from two Levy processes starting from the definition of the Levy process, and next we test if the two samples have the same distribution. Using the...

We present a comprehensive framework for comparing the merits of alternative portfolio insurance strategies in realistic contexts. Our findings add generality to previous results comparing option based and constant proportionality portfolio insurance strategies (OBPI and CPPI). The optimal OBPI...

Constant proportion portfolio insurance (CPPI) strategies implemented in continuous time on asset prices following geometric Brownian processes are expected utility maximising for investors with HARA utilities. But, in reality, these strategies are implemented in discrete time and asset prices...

Although the British Railway Mania has been described as one of the greatest bubbles in history, it has been largely neglected by academics. This paper attempts to redress this neglect by creating a daily stock price index for the 1843-50 period and by assessing the contribution of the many...

Commercial paper is one of the largest money market instruments and has long been viewed as a safe haven for investors seeking low risk. However, during the financial crisis of 2007-2009, the commercial paper market experienced twice the modern-day equivalent of a bank run with investors...
