Im Folgenden werden ausgewählte Ergebnisse einer neuen Datenquelle zur Messung von Wachstum und Produktivität im internationalen Vergleich präsentiert. Die Informationen decken den Zeitraum von 1970 bis 2004 ab. Sie zeigen, dass Deutschland seine langjährige Wachstumsführerschaft in Europa im Laufe der 90er Jahre verloren hat. Die aktuellen gesamtwirtschaftlichen Daten für 2006 sowie die Schätzungen ...
We analyse forecasts of professional forecasters for Germany regarding the time span from 1970 to 2004. This novel panel data set renders it possible to assess the accuracy and efficiency of growth and inflation forecasts more efficiently than in previous studies. We argue that the forecasts are, on average, unbiased and weakly - but not strongly - efficient. Using model confidence sets suggested by ...
The appropriately selected leading indicators can substantially improve the forecasting of the peaks and troughs of the business cycle. Using the novel methodology of the dynamic bi-factor model with Markov switching and the data for the three largest European economies (France, Germany, and UK) we construct a composite leading indicator (CLI) and a composite coincident indicator (CCI) as well as corresponding ...
Based on a panel of German professional forecasts for 1970-2004 we analyse the dispersion of growth and inflation forecasts. Forecast dispersion varies over time and is particularly high before and during recessions. There is no clear link between forecast dispersion and the subsequent forecast error. Forecast dispersion is positively correlated with the volatility of macroeconomic variables, but not ...
In this paper we perform a comparative study of the forecasting properties of the about 30 alternative leading indicators for Germany using the growth rates of German real GDP. In addition to them, we have constructed a diffusion index based on the principal component analysis and including 145 component series that reflect all the facets of German economy. We use the post-unification data which cover ...
