This study tests the hypothesis of the weak form of capital market efficiency in the Czech Republic. Select statistical-econometric methods were applied to time series of daily, weekly and two-week stock and indices returns over 1995 - 2001. Results from Serial Correlation, Box-Pierce, and...

Abstract: The scope of this paper is the presentation of a simple hypothesis test that enables to discern heteroscedastic data from homoscedastic i.i.d. gaussian white noise. The main feature will be a test statistic that’s easy applicable and serves well in committing such a test. The power...

This paper uses the classical (level) definition of business cycles to analyze the characteristics-duration, amplitude, steepness, and cumulative output movements-of the real GDP series of France, Germany, Italy, the rest of the euro area, and the United States. An index of concordance and its...

We propose using a Bayesian time-varying coefficient model estimated with Markov chain-Monte Carlo methods to measure contagion empirically. The proposed measure works in the joint presence of heteroskedasticity and omitted variables and does not require knowledge of the timing of the crisis. It...

“Program numbers” from a sample of IMF-supported programs are studied as if they were forecasts, through statistical analyses of the relationship between projections and outcomes for growth, inflation, and three balance of payments concepts. Statistical bias is found only for projections of...

This paper empirically investigates the relationship between privatization and measures of fiscal and macroeconomic performance. One of the main findings is that privatization proceeds transferred to the budget tend to be saved. Specifically, they are largely used to reduce domestic financing,...

Financial decisions of economic agents are based on volatility considerations. However, no aggregate indicators have been used by policymakers and regulators to assess the market risk environment. This paper applies a market volatility indicator to analyze the Israeli's transition toward...

A simple criterion based on the properties of the forecast error is presented to evaluate the accuracy of forecasts. The efficiency conditions of an optimization problem are used to show that under rational expectations the standard statistical conditions are necessary, but not sufficient to...

Some recent studies suggest the possibility of estimating a stable aggregate demand-for-money relationship for the group of countries participating in the European Monetary System. These results are of particular relevance in connection with the task of setting policy targets for a European...

This paper reviews the international business cycle among Group of Seven (G-7) countries since 1973 from two angles. An examination of business cycle synchronization among these countries using simple descriptive statistics shows that synchronized slowdowns have been the norm rather than the...
