Using the tick-by-tick yen/dollar exchange rate, this paper examines the effect of Japanese banking crisis in late 1997 on the foreign exchange market. By high-frequency methodology, GARCH estimation and variance-ratio tests, the existence of a structural break in the foreign exchange market at...

Macroeconomic or financial data are often modelled with cointegration and GARCH. Noticeable examples include those studies of price discovery, in which stock prices of the same underlying asset are cointegrated and they exhibit multivariate GARCH. Modifying the asymptotic theories developed in...

We examine the equity market price interdependence between Australia, on one hand, and Japan, US, UK, Hong Kong, Singapore, Taiwan and Korea, on the other hand, based on Hacker and Hatemi-J (2003) bootstrap causality tests with leveraged adjustments. We cover the period January 1, 1993 to...

This paper examines whether permanent earnings growth, crucial to stock valuation, increased during the last decade as suggested by proponents of the 'New Economy.' Using S\&P 500 earnings for 1951-2000, we do not find strong evidence of either a one-time structural break or gradual change....

This paper uses dynamic factor analysis to investigate the sources of foreign shocks and the propagation mechanism of these disturbances into two small open economies, Australia and Canada. Panels including a variety of foreign and domestic series for each country are used to estimate the...

The present paper applies the Markov switching model with the aim of checking two industrial production features of six major Brazilian states. Firstly, we try to determine the date of business cycles and, soon afterwards, we verify the existence or not of an unobservable component that is...

This paper shows that the Mexican experience from 1945 to 2002 is, like the German hyperinflation period, a unique monetary ``natural experiment,'' where fundamental relationships, like money demand, PPP and the monetary model of exchange rate determination can be analyzed with unparalleled...

In this paper it is shown that "classical" tests can become asymptotically inadmissible (i.e. we show that there exist uniformly better tests) if the information matrix becomes stochastic: A typical example is the augmented Dickey-Fuller test for unit roots (in case of no deterministic trend. We...

The notion of cointegration was developed by Engle and Granger (1987), and since then has been considered important in the recent development of time series econometrics. Many statistical methods have been developed for the analysis of the cointegrated systems, and several methods of estimating...
