Central bank FOREX interventions assessed using realized moments

This paper assesses the impact of G3 official central bank interventions on daily realized moments of DEM/USD exchange rate returns obtained from intraday data, 1989–2001. Event studies of the realized moments for the intervention day, the days preceding and following the intervention illustrate the shape of this impact. Rolling regressions results for an AR(FI)MA model for realized moments are used to measure the impact and its significance. The analysis confirms previous empirical findings of a temporary increase of volatility after a coordinated central bank intervention. It highlights new findings on the timing and the temporary nature of the impact of coordinated interventions on exchange rate volatility and on cross-moments between foreign exchange markets.     

The European exchange rate mechanism and the European monetary union

Summary This article addresses two central questions related to the prospects of the Economic and Monetary Union (EMU) in Europe: first, is the current exchange rate mechanism viable in the transition stage to EMU or in the period to come if the EMU should be postponed? Second, is a monetary union necessary in an economically fully integrated European Union or would the current or an alternative exchange rate mechanism suffice an integrating Europe? The article reviews the arguments for and against monetary union, the history of European monetary integration, the theoretical and empirical insights into the functioning of targets zones, and the likely developments and prospects for the EMU.The author wishes to thank Martin M.G. Fase and Simon K. Kuipers for their most helpful comments on a previous version of this article.     

FINANCIAL LITERACY AND PENSION INVESTMENT DECISIONS

The call for enhanced financial literacy amongst consumers is a global phenomenon, driven by the growing complexity of financial markets and products, and government concerns about the affordability of supporting an ageing population. Worldwide, defined benefit pensions are giving way to the risk and uncertainty of defined contribution superannuation/pension funds where fund members now make choices and decisions that were once made on their behalf. An important prerequisite for informed financial decision‐making is adequate financial knowledge and skills to make competent investment decisions. This paper reports the findings of an online survey of the members of a large Australian public sector‐based superannuation fund and shows that although respondents generally understand basic financial matters, on average, their understanding of investments concepts, such as the relationship between risk and returns, is inadequate. These results highlight the need for education programs focusing specifically on developing fund members’ investment knowledge and skills to facilitate informed retirement savings decisions.     

Long-Term Disabilities and College Education

This study focuses on the labor market consequences of long-term disability status for persons who have had the opportunity to receive both a university education and rehabilitation services. The sample matches persons with functional limitations with a similar sample of university graduates without these limitations. Our results indicate a small salary gap that appears to be correlated with the negative opinions held by the general population about persons with these disabilities.     

A parametric test of the negativity of the substitution matrix

The negativity of the substitution matrix implies that its latent roots are non-positive. When inequality restrictions are tested, standard test statistics such as a likelihood ratio or a Wald test are not X²-distributed in large samples. We propose a Wald test for testing the negativity of the substitution matrix. The asymptotic distribution of the statistic is a mixture of X²-distributions. The Wald test provides an exact critical value for a given significance level. The problems involved in computing the exact critical value can be avoided by using the upper and lower bound critical values derived by Kodde and Palm (1986). Finally the methods are applied to the empirical results obtained by Barten and Geyskens (1975).     

Studying co-movements in large multivariate data prior to multivariate modelling

For non-stationary vector autoregressive models (VAR hereafter, or VAR with moving average, VARMA hereafter), we show that the presence of common cyclical features or cointegration leads to a reduction of the order of the implied univariate autoregressive-integrated-moving average (ARIMA hereafter) models. This finding can explain why we identify parsimonious univariate ARIMA models in applied research although VAR models of typical order and dimension used in macroeconometrics imply non-parsimonious univariate ARIMA representations.
