Since the adoption of inflation rate targeting policy, there has been a great concern on the effectiveness of monetary policy to curb inflation in South Africa. The effectiveness of the repo rate as a policy instrument to control the level of inflation has been widely criticised not only in the...

This paper constructs an alternative investment strategy to portfolio optimization model in the framework of the Mean–Variance portfolio selection model. To differentiate it from the ubiquitously applied Mean–Variance model, which is constructed on an assumption that returns are normally...

This paper presents a forward looking model for selection of hedge fund investment strategies. Given excess skewness observed in hedge funds’ return distributions, we assume that the historical return distribution is a skewed student t distribution. We implement a Bayesian framework to derive...

This paper makes use of the performance evaluation to test the validity of the efficient market hypothesis (EMH) in hedge fund universe. The paper develops a fuzzy set based performance analysis and portfolio optimisation and compares the results with those obtained with the traditional...

This paper analyzes the effect of the recent market crash on the international diversification of equity portfolios from the perspective of dependence structure. We use the generalized Pareto distribution to fit the left and the right tail of each return distribution in order to evaluate the...

Recently, financial engineering has brought a significant number of interest rate derivative products. Amongst the variables used in pricing these derivative products is the short-term interest rate. This research article examines various short-term interest rate models in continuous time in...

This paper empirically compares the static unconditional Value-at-Risk (VaR) and conditional Value-at-Risk (CVaR) estimates based on two extreme value theory (EVT) distributions: the generalized extreme value distribution (GEV) and the generalized Pareto distribution (GPD); and two other...

This paper sets up a Bayesian framework to estimate hedge fund managers’ selectivity, market timing and outperformance skills separately, and investigates their persistence from January 1995 to June 2010. We divide this sample period into four overlapping sub-sample periods that contain...

The main objective of this paper is to examine the effect of exchange rate volatility on international trade. We show that the impact of exchange rate volatility on international trade could be either positive or negative depending on various reasons that are discussed in this study. We focus...
