"This report documents reasons, methods and results of the general revision
2014 of the IAB working-time measurement concept (AZR) for the period from
1991 to 2013. The AZR which is part of the German system of national accounts
(VGR) provides long comparable time series for industry-specific hours worked
and the volume of work for Germany. Since the concepts and definitions of the
VGR are also binding for the AZR, the 2014 general revision of the VGR leads
to changes regarding the concepts, methods and resulting time series. In this
context, we also take this as an occasion to revise and update statistical
methods and data sources of the AZR in its whole. A key part of the
methodological changes is due to the introduction of modern techniques of time
series analysis. By multivariate structural time series models embedded in a
state space framework, all available information can be exploited timely and
efficiently for estimating the different components of hours worked. In this
context a new approach is proposed which makes the use of a multiplicity of
relevant time series for structural time series models feasible by principal
components methods. This would otherwise be possible with a high computational
cost only. In the following, we present the base concept of the AZR, and outly
the changes of the revision of the VGR as well as its impact on the AZR. We
describe the foundation of the estimation methods and discuss methodological
developments as well as estimates for the respective components of hours
worked. A subsequent section depicts the most relevant results of the revision
for the period from 1991 to 2013 and compares results before and after the
revision." (Author's abstract, IAB-Doku) ((en)) |
