Gegenstand der Studie ist die Quantifizierung des gleichsam automatischen Einflusses der wirtschaftlichen Entwicklung auf einzelne Budgetkomponenten und das Budget insgesamt, um den Effekt einer hypothetischen Änderung in der Entwicklung des Outputs auf das Budget und das Defizit abzuschätzen...

Das ifo Institut begleitet seit seiner Gründung im Jahr 1949 das aktuelle Wirtschaftsgeschehen durch seine regelmäßigen Konjunkturumfragen und Konjunkturprognosen. Daneben hat das ifo Institut aber immer auch Aufsätze zur methodischen Basis seiner Konjunkturforschung veröffentlicht. Die...

This paper deals with the effects to labour market institutions on labour market performance. We analyse the employment threshold (the minimum growth rate necessaryto keep employment constant) which is an indicator for the labour intensity of production. We show for 17 OECD countries for the...

The concept of the employment threshold plays an important role in the public discussion of unemployment. The employment threshol d is defined as that growth rate of output which is necessary to keep employment constant despite the continuous rise in labour productivity. It is related to the...

This paper deals with the estimation of the output gap. We use uni- and bivariate unobserved components models in order to decompose the observed German GDP-series into trend, cycle and seasonal components. The results show that using the ifo business assessment variable as an indicator for the...

In this paper, an Unobserved Components Model is employed to decompose German real GDP into the trend, cycle and seasonal components and the working day effect. The most important findings are: 1) The growth rate of potential output declined from 4.2 per cent in the sixties to 1.4 per cent at...

In this paper an Unobserved Components Model is employed to decompose U.S. real GDP into trend and cycle components. The main findings are that there exist three cycles with a period of about two, five and 13 years, respectively, and that the long-run development during the last 50 years can be...

The production index is an important indicator for assessing the cyclical state of the economy. Unfortunately, the monthly time series is contaminated by many noisy components like seasonal variations, calendar and vacation effects. Only part of those nuisance components are explicitly...

The HP filter is the most popular filter for extracting the trend and cycle components from an observed time series. Many researchers consider the smoothing parameter lambda = 1600 as something like an universal constant. It is well known that the HP filter is an optimal filter under some...
