Konjunkturprognostiker und deren prognostische Fähigkeiten standen schon oft im Kreuzfeuer der öffentlichen Kritik. Seit einiger Zeit mehren sich die Fragen über die Tauglichkeit von Konjunkturprognosen. Da war vom "Blindflug der Forscher" zu lesen (vgl. Der Spiegel 2005), Feuilletonisten...

The paper discusses some widely used methods for estimating output gaps based on aggregated datafor the Euro-zone. Though these methods exhibit some common features, an empirical comparisondemonstrates that the various techniques differ substantially. In particular, the correlation of output...

In a standard dynamic stochastic general equilibrium framework, with sticky prices, the cross sectional distribution of output and inflation across a population of firms is studied. The only form of heterogeneity is confined to the probability that the ith changes its prices in response to a...

Aggregated output in industrialized countries has become less volatile over the past decades. Whether this Great Moderationʺ can be found in firm level data as well remains disputed. We study the evolution of firm level output volatility using a balanced panel dataset on German firms that...

Using data from the OECD Regional Well-Being Index - a set of quality-of-life indicators measured at the sub-national level, we construct a set of composite well-being indices. We analyse the extent to which the choice of five alternative aggregation methods affects the well-being ranking of...
