The flow of information between futures and spot prices may vary over time, in particular during periods of stress. This article analyses the information content of the Bund Future and German government bonds during 1998 and test whether it is constant over time. The use of high-frequency data...

This paper explores the evolving relationship in the volatility of sovereign yields in the European Economic and Monetary Union (EMU). To that end, we examine the behaviour for daily yields for 11 EMU countries (EMU-11), during the 2001-2010 period. In a first step, we decompose volatility in...

In this paper we investigate the relationship between volatility, measured by realized volatility, and trading volume. We show that volume and volatility are long memory but they are not driven by the same latent factor as suggested by the fractional cointegration analysis. We analyze the degree...

On the basis of a unique database of policy makers' comments, we find that central bank communication does influence behavior of financial markets. This effect is asymmetric and depends on the contents and direction of the statements. Moreover, we investigate whether individual characteristics...

There exist dual-listed stocks which are issued by the same company in some stock markets. Although these stocks bare the same firm-specific risk and enjoy identical dividends and voting policies, they are priced differently. Some previous studies show this seeming deviation from the law of one...

Asset valuations can be made in absolute or relative terms. Relative valuation means that two close substitute assets, whose cash flows and risks are determined by the same business factors, must worth the same. But it is not established or specified at what price level. The Law of One Price...

In the context of an international portfolio diversification problem, we find that small capitalization equity portfolios become riskier in bear markets, i.e. display negative co-skewness with other stock indices and high co-kurtosis. Because of this feature, a power utility investor ought to...

The paper investigates the effect of interest rate variance on the shape of the yield curve using a bivariate 2-state Markov switching model for the short rate changes and the yield curve slope. The two states are characterized by the variance of the short rate changes: Low and high variance. In...

In a context where European stock prices have been trending upwards, one of the main concerns is that stocks perceived as more sustainable from an environmental, social and governance (ESG) perspective could be particularly exposed to exuberance. To shed some light on the magnitude of the...
