Using high-frequency data on Deutschemark and Yen returns against the dollar, we construct model-free estimates of daily exchange rate volatility and correlation, covering an entire decade. In addition to being model-free, our estimates are also approximately free of measurement error under...

In this paper we use three euro exchange rates to test for the presence of volatility spillovers, common volatility components and time-varying correlations using the multivariate-GARCH model and the common volatility methodology approach proposed by Engle and Kozicki (1993). Our results suggest...

Fluctuations of yen exchange rate to US-dollar are analyzed by a method of classical mechanics. The fluctuations are explained by a linear inhomogeneous differential equation of the second order with a constant coefficient. The inhomogeneous term is an external force. Using a method of the least...
