Die Arbeiten am sozioökonomischen Modell DEMOS der GWS mbH gehen auf die Arbeiten der Kooperationsgruppe Sozioökonomische Modellierung am Zentrum für interdisziplinäre Forschung der Universität Bielefeld (ZiF) im Jahre 2004 zurück. Beteiligt waren Peter Bartelheimer (SOFI), Joachim Frohn...

The empirical performance of macroeconomic exchange rate models is more than disappointing. This dismal result is also reflected in the forecasting capabilities of professional analysts: all in all, analysts are not in a position to beat native random walk forecasts. The root for this deficient...

Certainly the current crisis is affecting seriously the convergence process in EU. Starting from the spatial distribution in EU of some fundamental development indicators before the current crisis, we try to estimate the impact of the prolonged crisis. During last years, the less developed...

The preliminary evidence in the literature suggests that changes in uncertainty have a role in shaping the U.S. economic cycle. But what is effectively measured by the different available indicators of uncertainty still remains an "uncertain" issue. This paper has two aims: (i) to introduce a...

We study the loss function of 15 European governments as implied by their budget balance forecasts. Results suggest that the shape of the loss function varies across countries. The loss function becomes more asymmetric as the forecast horizon increases and in advance of parliamentary election....

The use of large datasets for macroeconomic forecasting has received a great deal of interest recently. Boosting is one possible method of using high-dimensional data for this purpose. It is a stage-wise additive modelling procedure, which, in a linear specification, becomes a variable selection...

There are evidences that the actual global crisis affected the convergence process in EU. Generally, just new adhered countries were more affected by the actual crisis. Today all forecasts are suffering by uncertainty. Last time, economists, with their methods and models, are invoked for actual...

This study introduces a monthly coincident indicator for consumption in Germany based on Google Trends data on web search activity. In real-time nowcasting experiments the indicator outperforms common survey-based indicators in predicting consumption. Unlike those indicators, it provides...

In this paper, an econometric model of consumption in Bulgaria for the period 1997-2005 is constructed. The Error-Correction Model (ECM) approach is employed and long-run relationship between household consumption and income was found. The primary purpose of this empirical paper is to get a...

Recent work by Clements and Hendry have shown why forecasting systems that are in terms of differences, dVARs, can be more accurate than econometric models that include levels variables, ECMs. For example, dVAR forecasts are insulated from parameter non-constancies in the long run mean of the...
