Based on a panel of German professional forecasts for 1970 to 2003 we find that growth and inflation forecasts are unbiased and weakly, but not strongly efficient. Besides the effect of diverging forecasting dates, no other substantial differences in forecasting quality are found among...

There is a broad agreement that transportation activity is closely linked to the business cycle. Nevertheless, data from the transportation sector have not been part of the tool kit of business cycle analysts due to long publications lags. With the disseminations of electronic road pricing...

We estimate a Markow-switching dynamic factor model with three states based on six leading business cycle indicators for Germany preselected from a broader set using the Elastic Net soft-thresholding rule. The three states represent expansions, normal recessions and severe recessions. We show...

We present a comprehensive disaggregate approach for short-term forecasting economic activity in Germany by explicitly taking into account the supply or production side and the demand side of GDP. The GDP figures calculated by the two sides usually yield different results and the official GDP...

We use Bayesian additive regression trees to reexamine the efficiency of growth and inflation forecasts for Germany. To this end, we use forecasts of four leading German economic research institutes for the sample period from 1970 to 2016. We reject the strong form of forecasts efficiency and...

Do firms learn to forecast future business conditions after major structural changes to the economy? How long does it take? We exploit German Reunification as a natural experiment, where firms in the East are treated with ignorance about the distribution of market states, to test a Bayesian...

From 2014 until present, housing prices in Germany have been rising faster than consumer prices in all quarters except one, raising concerns about an excessive over-heating of the housing market. To assess the vulnerability of the German housing market to a future realignment of prices or even a...

This paper presents a revised version of the DIW Economic Barometer, the business cycle index of the German Institute for Economic Research (DIW Berlin). As in earlier versions, we put forward a factor model on a monthly frequency to filter the latent state of the aggregate economy. In the new...

We evaluate the economic value of business cycle forecasts for potential investors on financial markets as opposed to statistical measures of forecasts accuracy. Taking Germany as an example, and based on annual data ranging from 1990 to 2016 covering 16 institutions and 18 different forecasts,...

In this paper the accuracy of a wide range of German business cycle forecasters is assessed for the past 10 years. For this purpose, a data set is used comprising forecasts published on a monthly basis by Consensus Economics. The application of several descriptive as well as statistical measures...
