This paper examines several US monthly financial time series data using fractional integration and cointegration techniques. The univariate analysis based on fractional integration aims to determine whether the series are I(1) (in which case markets might be efficient) or alternatively I(d) with...

In this paper we use fractional integration techniques to examine the degree of integration of four US stock market indices, namely the Standard and Poor, Dow Jones, Nasdaq and NYSE, at a daily frequency from January 2005 till December 2009. We analyse the weekly structure of the series and...

In wissenschaftlichen Veröffentlichungen müssen häufig numerische Sachverhalte dargestellt werden. Dies kann in Form von Tabellen oder in Form von Schaubildern geschehen. Während eine Tabelle zur Darstellung einzelner Zahlen oder Matrizen (Input-Output-Tabelle) geeignet ist, lassen sich...

The German current account balance has moved from surplus to deßcit in the course of unificalion. A theorelical model for the current account, encompassing the elaslicities, the monetary, and the absorptions approach, is set up and lested for Germany and the United States, using cointegration...

The paper presents some stylized facts of Euroland's business cycle using aggregated data. The main results are: The determination of turning points in Euroland's business cycle is not very sensitive to the detrending method used, although the level of the recent output gap depends on it....

This paper provides a novel approach to forecasting time series subject to discrete structural breaks. We propose a Bayesian estimation and prediction procedure that allows for the possibility of new breaks over the forecast horizon, taking account of the size and duration of past breaks (if...

We investigate the effect of forecast uncertainty in a cointegrating vector error correction model for Switzerland. Forecast uncertainty is evaluated in three different dimensions. First, we investigate the effect on forecasting performance of averaging over forecasts from different models....

New Keynesian Phillips Curves (NKPC) have been extensively used in the analysis of monetary policy, but yet there are a number of issues of concern about how they are estimated and then related to the underlying macroeconomic theory. The first is whether such equations are identified. To check...
