In the literature on the empirical unconditional distribution of forein exchange rate returns there is indication that the type of distribution function is related to the form of the exchange rate regime. The analysis has been hampered by the nonnestedness of the alternative distribution models....

This paper compares foreign exchange market intervention in case there is no uncertainty about the extent of an imperfectly sustainable target zone and where there is uncertainty. A well-known example of the first case was the European Monetary System between 1979 and 1992. An example of the...

The discrete time analogue of the continuous time Krugman target zone model is developed in order to capture the typical volatility clusters and fat-tailed distributed innovations of exchange rates. It is shown that under these more general stochastic conditions the S-shaped relation between...

In this paper, we analyze bilateral real exchange rate behavior for fifteen countries over the period May 1925 to December 1937, using a modified principal components technique that is invariant to the choice of benchmark currency. For the gold exchange rate period May 1925 - August 1931, we...

Systemic crises can have grave consequences for investors in international equity markets, because they cause the risk-return trade-off to deteriorate severely for a longer period. We propose a novel approach to include the possibility of systemic crises in asset allocation decisions. By...

Using an international database containing 103 German, UK and US ethical mutual funds we review and extend previous research on ethical mutual fund performance. By applying a multi-factor Carhart (1997) model we overcome the benchmark problem most prior ethical studies suffered from. After...

Analysis of 3,300 stocks from nine industrialized countries over the 1980-99 period indicates that whether the capital asset pricing model or some form of international CAPM is used makes little difference in the cost-of-capital estimate for most companies in most countries. The international...

A number of studies have provided evidence of increased correlations in global financial market returns during bear markets. Other studies, however, have shown that some of this evidence may be biased. We derive an alternative to previous estimators for implied correlation that is based on...

Benefits to portfolio diversification depend crucially on correct correlation estimates, hence it is of great importance to both risk management and portfolio optimisation that the exact nature of the correlation structure between international financial assets is understood. Recent discussion...

Using data on Asian equity markets, we observe that during periods of financial turmoil, deviations from the mean-variance framework become more severe, resulting in periods with additional downside risk to investors. Current risk management techniques failing to take this additional downside...
