This paper investigates the differences between directly and indirectly seasonally adjusted aggregates. This difference is derived analytically for linear seasonal adjustment methods. GDP data for five European countries and three classes of seasonal adjustment methods are used to show...

In this paper we present a methodology which can help to improve the assessment of the current economic situation. We propose an approach which combines multivariate single equations to forecast the monthly growth rate of industrial production with a density forecast. This allows to estimate the...

Germany's CPI inflation stood at 6.1% in May 2023 and was thus more than one percentage point lower than in April 2023 (7.2%). Food prices contributed slightly less to inflation, but at 2.1 percentage points still almost seven times as much as usual. The contribution of household energy was nine...

Empirical studies analysing German import demand functions traditionally report implausibly high income and relative low price elasticities. Furthermore, estimation results strongly depend on the observation period. Minor variations in the estimation period typically lead to insignificant price...
