Measuring Modern Business Investment: A Case Study for Germany
An extended concept for intangible investment does not lead to additional investment momentum in the case of Germany. This corresponds to experiences with former extension of investments in national accounts. Also, growth in real GDP and the related labour productivity dynamics are not higher when a broader definition of investment in the form of intangibles is applied. Even if the investment processes are defined beyond the measurement concept for intangibles established by Corrado, Hulten and Sichel, there are no fundamentally different findings for German investment dynamics based on a special company survey. However, these findings should not be misunderstood as suggesting there is no need for action in terms of statistical measurement. Extended concepts and estimates signal for Germany considerable level effects of a more broadly defined investment concept.

The Digital Revolution – New Challenges for National Accounting?
The digital revolution has changed many industries, but measuring these changes from a national accounting perspective causes problems. Generally, in the transition periods during the introduction of new technologies, marked setbacks in the estimation of productivity growth are possible. Whereas new private goods are partly invisible in the national accounts because of measurement lags due to outdated accounting standards, more often only their negative substitution effects turn up in GDP measures. If this causes a market phenomenon it should be reflected initially in a weaker market production and productivity. In order to capture new private digital goods and their welfare effects a separate documentation of their introduction in a ‘satellite account’ is recommended.

Are National Accounts Revisions Harmful for Historical Comparisons?
Revisions of national accounts affect economic analysis, calling into question theoretical findings based on earlier data. Revisions to German national accounts have resulted in a markedly higher GDP in absolute terms and a lower volatility in macroeconomic production. According to the revised data, recessions have been less pronounced. Moreover, less volatility in production has changed income accounts and, above all, reduced the fluctuations in property and entrepreneurial income. The stylised fact of declining property and entrepreneurial incomes during recessions in West Germany from 1970 to 1991 has vanished into thin air as a result of the revisions of 2002 and 2006.
