Is there a connection between monetary unification and real economic integration? Evidence from regime-switching stationarity tests

　View Summary

We investigate the extent of real convergence among G7 economies in terms of long-rum real interest parity. A novel approach is applied where unit-root tests of real interest differentials are embedded within a Markov regime-switching framework. Whereas standard univariate unit-root tests provide little support for parity, we find real convergence is present after allowing for regime switches in real interest misalignments. However, differentials across members of the euro zone are likely to exhibit greater persistence despite nominal convergence. It is non-sequitur to infer from monetary unification that nominal convergence is necessarily conducive to real interest realignments or preventive of misalignments. (C) 2008 Elsevier Ltd.

The KOSPI200 implied volatility index: Evidence of regime switches in volatility expectations

ASIA-PACIFIC JOURNAL OF FINANCIAL STUDIES ( KOREAN SECURITIES ASSOC )  36 ( 2 ) 163 - 187   2007  [Refereed]

　View Summary

This study develops a new KOSPI200 implied volatility index and examines its informational content and nonlinear dynamics. The construction of this new benchmark for volatility expectations follows the methodology for calculating the new VIX index from S&P500 options. The empirical evidence suggests that the expected level of volatility in the Korean stock market has been steadily falling since the inception of option trading and the onset of the Asian financial crisis. Implied volatility is found to reflect useful information on future volatility that is not contained in the history of returns, even after allowing for leverage effects. Markov regime-switching models suggest that nonlinearities in volatility expectations are not likely to be driven solely by the asymmetric impact of news but also by regime-dependencies in the realignment mechanism adjusting for forecast errors. The adjustment process is likely to be significant during regimes of lower volatility expectations but financial crises seem to elevate the level of anticipated volatility and impair its adaptive dynamics.

Are international real interest rate linkages characterized by asymmetric adjustments?

Mark J. Holmes, Nabil Maghrebi

Journal of International Financial Markets, Institutions and Money   16 ( 4 ) 384 - 396   2006.10  [Refereed]

　View Summary

This study tests for asymmetries in the adjustment mechanism towards real interest parity using monthly data over the period 1973-2004 for the U.S. and a sample of other OECD economies. There is stronger evidence of long-run cointegrating relationships when an explicit distinction is made between decreasing and increasing deviations from equilibrium. The speed of mean-reversion tends to be fastest when momentum gathers for increasing rather than decreasing deviations. This evidence is consistent with asymmetric monetary policy responses where close linkages with respect to the U.S. are likely to be less prevalent in a regime of rising nominal interest rates and falling inflation. © 2005 Elsevier B.V.
