We assess whether the euro had an impact first on the degree of integration of European financial markets, and, second, on the euro area term structure. We propose two methodologies to measure integration: one relies on time-varying GARCH correlations, and the other one on a regression...

We investigate the existence and significance of a cross-sectional relation between idiosyncratic volatility and expected returns at the global level by introducing a global idiosyncratic volatility measure and globally diversified test assets. We find that the portfolios with the highest and...

With the rapid growth of countries' foreign asset and liability positions over the last two decades,financial returns on those positions ('NFA returns') have become material drivers of current accounts and net stock positions. This paper documents the relative importance of NFA return versus...

This study presents empirical evidence that volatility persistence and asymmetry are jointly affected by market conditions such as return and volatility. Using 28 equity market indices in developed and emerging countries, we show that daily volatility persistence increases with returns,...

This paper proposes a measure of exchange rate disconnect. Working in a two-currency international economy, our theory implies that the disconnect is the ratio of two martingales. Weanalyze empirically our measure of disconnect using 406 pairs of economies to reveal a geography of disconnect....

The study of international integration of equity markets has received a great deal of interest. This paper investigates whether returns of 41 closed-end country funds share a common volatility process with three comparable return-series: the underlying net asset value (NAV), the U.S., and the...

I investigate the time variation in the integration of EU government bond markets. The integration is measured by the explanatory power of European factor portfolios for the individual bond markets for each year. The integration of the government bond markets is stronger for EMU than non-EMU...

We examine whether there is a relationship between foreign equity trading and average total volatility, measured as the value-weighted average of stock-return variances in the Istanbul Stock Exchange. We employ foreign equity purchase and sale data to track changes in foreign equity trading,...

This study compares two channels for global impact on local volatility: the direct channel in which global variables affect the expected value of local volatility but not its persistence, and a new channel in which global variables affect local volatility by changing its persistence over time....
