This paper presents a new method of testing for IID. The test is suggested as an alternative to the nonparametric BDS test, which requires a proximity parameter (and an embedding dimension m to be chosen arbitrarily. A limited statistical theory exists to determine the right choice of these...

In recent years, analysis of financial time series has focused largely on data related to market trading activity. Apart from modelling the conditional variance of returns within the GARCH family of models, presently attention has also been devoted to other market variables, especially volumes,...

Consider forecasting the economic variable Y_{t h} with predictors X_{t}, where h is the forecast horizon. This paper introduces a semiparametric method that generates forecast intervals of Y_{t h}|X_{t} from point forecast models. First, the point forecast model is estimated, thereby taking...

This paper builds on Kocenda (2001) and extends it in two ways. First, two new intervals of the proximity parameter ε (over which the correlation integral is calculated) are specified. For these ε-ranges new critical values for various lengths of the data sets are introduced and through Monte...

This paper introduces an alternative testing procedure to test the distribution of the error term in the Autoregressive Conditional Duration (ACD) class of models. In these models, the error term is normally interpreted as the standardized duration by which its probability distribution may have...

The coordination channel has been proposed as a means by which foreign exchange market intervention may be effective, in addition to the traditional portfolio balance and signaling channels. If strong and persistent misalignments of the exchange rate are caused by non-fundamental influences,...

This paper applies nonlinear econometric models to empirically investigate the effectiveness of the Reserve Bank of Australia (RBA) exchange rate policy. First, results from a STARTZ model are provided revealing nonlinear mean reversion of the Australian dollar exchange rate in the sense that...

This paper attempts to assess the extent of volatility spillovers between the equity market and the foreign exchange market in South Africa. The multi-step family of GARCH models are used for this end, whereby volatility shocks obtained from the mean equation estimation in each market are...

We fit nonlinearly mean-reverting models to real dollar exchange rates over the post-Bretton Woods period, consistent with a theoretical literature on transaction costs in international arbitrage. The half lives of real exchange rate shocks, calculated through Monte Carlo integration, imply...

In this Paper we assess the progress made by the profession in understanding whether and how exchange rate intervention works. To this end, we review the theory and evidence on official intervention, concentrating primarily on work published within the last decade or so. Our reading of the...
