Struggle for clarity
The coronavirus crisis has hit the German economy with unprecedented force. The simultaneity of multiple supply and demand shocks is likely unique in terms of previous economic crises. It is not yet possible to estimate how the virus will spread and what the human cost will be. Neither is it apparent how effective the health and economic countermeasures, some of which are very extensive, will be in many countries. This is now true in particular for strategies to lift the lockdowns (Hüther/Bardt, 2020).
In this context, there is also a high degree of uncertainty about the duration and extent of the diverse effects on supply and demand. The economic indicators normally referred to are available, but with the usual time delay. At the same time, there is up-to-date information available from business surveys. The impact of the coronavirus epidemic on German companies’ business processes are also identified via the regular business survey conducted by the German Economic Institute (see Grömling, 2018, for details on this economic survey). Given the extraordinarily high demand for information and the assumption that companies’ assessments could change significantly in the short term, since the beginning of March, the IW survey has been carried out weekly. It has investigated the impact in spring/summer 2020 as well as for 2020 and 2021. In each case, businesses were able to select strong, weak or no impact, which should help to assess the extent of the disruption. Furthermore, the survey asked about the duration and causes of the disruption. For more details on the method, scope and interpretation of the current survey results, see Bardt/Grömling (2020).
Coronavirus fever curve for Germany
The bold line in the figure below shows the overall course of what is being referred to as the coronavirus fever curve for Germany, from the beginning of March to the beginning of May 2020, i.e. ten calendar weeks. It shows the proportion of businesses surveyed by the German Economic Institute which expect the coronavirus pandemic to have a strong impact on their business processes in spring/summer 2020.
