We seek for verification and explanation of arbitrage between securities of dual-listed Brazilian-based companies which are simultaneously traded on the Brazilian and the US stock markets. Following the extant literature, our underlying hypothesis is that arbitrage events can be explained by...

Using a Markov switching model applied to the VIX and VDAX implied volatility indexes, we find that the volatility of the U.S. S&P100 index and German DAX index switched from a low-value state to a high-value state around the events of the Asian financial crisis. Moreover, the U.S. and German...

In the paper a realized regression version of the Britten-Jones (1999) portfolio selection approach is proposed, yielding a conditional mean-variance efficient portfolio selection strategy. Application to euro area stock markets diversification, differently from other standard approaches,...

A new approach to mean-variance efficient portfolio selection is introduced. The method is based on realized regression theory and the regression based portfolio selection approach of Britten-Jones (1999), yielding a conditional version of the Britten-Jones (1999) method. Application to euro...

This paper uses a novel variant of identification through hetroscedacity to estimate spillovers across U.S., Euro area, Japanese, and UK government bond and equity markets in a vector autoregression. The results suggest that U.S. financial shocks reverberate around the world much more strongly...

We show that internationally diversified portfolios carry sizeable political risk premia. We use a tail-risk portfolio selection model to obtain political efficient frontiers from skewed return distributions and manage political risk, and design an inference test to draw conclusions. We find...

In this paper, we contribute to the literature on international stock market comovement. The novelty of our approach lies in usage of wavelet tools to high-frequency financial market data, which allows us to understand the relationship between stock market returns in a different way. Major part...

The exchange markets and the exchange rates of Asia and Latin America are studied econometrically. Endogenous structural change and cointegration analyzes and impulse-response functions are used. The findings indicate that: 1) the long-term timing of the exchange markets is low; 2) there is no...

This paper examines long memory volatility in international stock markets. We show that long memory volatility is widespread in a panel dataset of eighty-two countries and that the degree of memory in the panel can be related to macroeconomic variables such as short- and long-run interest rates...

This paper investigates whether gold and silver can be considered safe havens by examining their long-run linkages with 22 stock price indices. More specifically, the stochastic properties of the differential between gold/silver prices and 22 stock indices are analysed applying fractional...
