Investment, output gap, and public finances in the medium term: Implications of the Second Supplementary Budget 2021
With the Second Supplementary Budget 2021, the German government plans to allocate a reserve of 60 billion euros to the Energy and Climate Fund. This additional spending is also meant to reduce the macroeconomic follow-up costs of the pandemic. According to the IWH’s medium-term projection, the expenditure is expected to increase output by about 0.5% at the peak of its impact in 2024. “While this macroeconomic effect is welcome, the additional investment will by no means compensate for the lack of investment activity since the beginning of the pandemic,” says Oliver Holtemöller, head of the Department Macroeconomics and vice president at Halle Institute for Economic Research (IWH). Moreover, the supplementary budget is likely to reduce confidence in the reliability of the debt brake.

Spillover Effects in Empirical Corporate Finance
Tobias Berg, Markus Reisinger, Daniel Streitz
Journal of Financial Economics,
No. 3,
2021
Abstract
Despite their importance, the discussion of spillover effects in empirical research often misses the rigor dedicated to endogeneity concerns. We analyze a broad set of workhorse models of firm interactions and show that spillovers naturally arise in many corporate finance settings. This has important implications for the estimation of treatment effects: i) even with random treatment, spillovers lead to a complicated bias, ii) fixed effects can exacerbate the spillover-induced bias. We propose simple diagnostic tools for empirical researchers and illustrate our guidance in an application.

German economy not yet immune to COVID 19 ‒ outlook clouded again
The current pandemic wave and supply bottlenecks cause the German economy to stagnate in winter. When infection rates go down in spring, private consumption will increase significantly. In addition, supply restrictions will be gradually reduced. As a result, the economy will regain momentum. The Halle Institute for Economic Research (IWH) forecasts that German gross domestic product will increase by 3.5% (East Germany: 2.7%) in 2022, after 2.7% (East Germany: 2.1%) in the current year. Inflation is expected to decline only slowly.

Non-Standard Errors

Abstract
In statistics, samples are drawn from a population in a datagenerating process (DGP). Standard errors measure the uncertainty in sample estimates of population parameters. In science, evidence is generated to test hypotheses in an evidencegenerating process (EGP). We claim that EGP variation across researchers adds uncertainty: non-standard errors. To study them, we let 164 teams test six hypotheses on the same sample. We find that non-standard errors are sizeable, on par with standard errors. Their size (i) co-varies only weakly with team merits, reproducibility, or peer rating, (ii) declines significantly after peer-feedback, and (iii) is underestimated by participants.

IWH Bankruptcy Update: Still No Indication of Impending Bankruptcy Wave
The number of corporate bankruptcies in Germany edged slightly upward in October following several months of historic lows. The number of jobs impacted by bankruptcy also remained unusually depressed. These are the headline figures from this month’s IWH Bankruptcy Update, a report on German bankruptcy statistics published by the Halle Institute for Economic Research (IWH).

Crisis is gradually being overcome – align actions to lower growth
The Corona pandemic still shapes the economic situation in Germany. A complete normalisation of contact-intensive activities is not to be expected in the short term. In addition, supply bottlenecks are hampering manufacturing for the time being. The German economy will reach normal capacity utilisation in the course of 2022. In their autumn report, the leading economic research institutes forecast that Gross Domestic Product (GDP) will rise by 2.4% in 2021 and by 4.8% in 2022.

IWH Bankruptcy Update: Bankruptcy Figures Remain Low; More Manufacturing Jobs Impacted
The number of corporate bankruptcies in Germany remained near to a historic low in September. However, there was a considerable increase in the share of manufacturing jobs impacted by bankruptcy. These are the key findings of the IWH Bankruptcy Update, published by the Halle Institute for Economic Research (IWH), which provides monthly statistics on corporate bankruptcies in Germany.

Production bottlenecks delay recovery
The German recovery made good progress over the summer 2021. However, bottlenecks in sea transport and the production of intermediate goods are weighing on world trade. The rise in raw material prices has prompted inflation rates to spike, and an increase in new infections is clouding the outlook again. A weak final quarter is therefore to be expected. The Halle Institute for Economic Research (IWH) forecasts that German gross domestic product (GDP) will increase by 2.2% in 2021 and 3.6% in 2022 (East Germany: 1.8% and 2.8%).
