The theory of self-fulfilling currency attacks predicts that pegged foreign exchange rates are extremely sensitive to adverse and hostile speculation. This is true whenever fiscal policy and monetary policy are inconsistent with each other, or even when intensive and public official intervention...

The interaction between stock market and monetary variables in Pakistan using monthly data for the last 20 years is examined. The Johansen co-integration approach is utilised to examine the equilibrium relationship between the stock price index, money supply, interest rates and a foreign...

Previously we have put forward that the sluggish convergence of truncated Lévy flights to a Gaussian (Phys. Rev. Lett. 73 (1994) 2946) together with the scaling power laws in their probability of return to the origin (Nature 376 (1995) 46) can be explained by autocorrelation in data (Physica A...

This paper investigates the possible asymmetric response of 5-min intraday JPY/USD exchange rates to macroeconomic news announcements during 1999–2006 when the Japanese money market interest rate was effectively zero. This period provides a unique institutional setting when interest rates may...

We suggest that the ultraslow speed of convergence associated with truncated Lévy flights (Phys. Rev. Lett. 73 (1994) 2946) may well be explained by autocorrelations in data. We show how a particular type of autocorrelation generates power laws consistent with a truncated Lévy flight. Stock...
