War drives up energy prices ‒ High inflation weighs on economy
While the lifting of nationwide coronavirus regulations boosts many service sectors such as the hospitality industry, supply bottlenecks are likely to weigh on the manufacturing sector throughout the summer and high inflation will dampen private consumption. Gross domestic product (GDP) in Germany is expected to decline slightly in the second quarter of 2022. The situation in the manufacturing sector is expected to ease towards the end of the year. The Halle Institute for Economic Research (IWH) forecasts that GDP will increase by 1.5% in 2022, following an increase by 2.9% in 2021. In East Germany, GDP will increase by 1%.

Price shock jeopardises recovery of German economy
Russia’s war in Ukraine is hitting the German economy primarily via an energy price shock, but also by disrupting trade flows and causing general uncertainty. At the same time, however, the economy is receiving a strong boost from the lifting of many pandemic restrictions. The Halle Institute for Economic Research (IWH) forecasts that gross domestic product will increase by 3.1% in 2022. The consumer price index will be 4.8% higher than one year ago. The war affects the East German eco-nomy about as hard as the economy in Germany as a whole.

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.

Why Are Households Saving so much During the Corona Recession?

IWH Policy Notes,
No. 1,
2021
Abstract
Savings rates among European households have reached record levels during the Corona recession. We investigate three possible explanations for the increase in household savings: precautionary motivations induced by increased economic uncertainty, reduced consumption opportunities due to lockdown measures, and Ricardian Equivalence, i.e. increases in the expected future tax-burden of households driven by increases in government debt. To test these explanations, we compile a monthly panel of euro area countries from January 2019 to August 2020. Our findings indicate that the chief driver of the increase in household savings is supply: As governments restrict households’ opportunities to spend, households spend less. We estimate that going from no lockdown measures to that of Italy’s in March, would have resulted in the growth of Germany’s deposit to Gross Domestic Product (GDP) ratio being 0.6 percentage points higher each month. This would be equivalent to the volume of deposits increasing by roughly 14.3 billion euros or 348 euros per house monthly. Demand effects, driven by either fears of unemployment or fear of infection from COVID-19, appear to only have a weak impact on household savings, whereas changes in government debt are unrelated or even negatively related to savings rates. The analysis suggests that there is some pent-up demand for consumption that may unravel after lockdown measures are abolished and may result in a significant increase in consumption in the late spring/early summer 2021.

New wave of infections delays economic recovery in Germany
The lockdown is causing production in Germany to decline at the end of the year. When restrictions will be relaxed again, the recovery is likely to pick up pace only slowly, partly because the temporary reduction in value-added taxes is expiring. In spring, milder temperatures and an increasing portion of the population being vaccinated are likely to support the German economy to expand more strongly. The Halle Institute for Economic Research (IWH) forecasts that gross domestic product will increase by 4.4% in 2021, following a 5% decline in 2020. In East Germany, both the decline and the recovery will be significantly less pronounced.

Recovery Loses Momentum ‒ Economy and Politics Still Shaped by the Pandemic
The corona pandemic leaves substantial marks in the German economy and its impact is more persistent than assumed in spring. In their autumn report, the leading German economic research institutes have revised their economic outlook downwards by roughly one percentage point for both this and next year. They now expect gross domestic product to fall by 5.4% in 2020 (previously -4.2%) and to grow by 4.7% (5.8%) in 2021 and 2.7% in 2022.

The economy adapts to the pandemic
In the first half of 2020, the pandemic has exacted a heavy toll on the German economy, causing a slump in production that will not be fully recovered within the next year. According to IWH summer economic forecast, gross domestic product is expected to contract by 5.1% in 2020 and to increase by 3.2% in 2021. The decline in production in Eastern Germany is likely to be less pronounced compared to Germany as a whole and estimated at 3.2% in 2020.

Global economy under the spell of the coronavirus epidemic
The epidemic is obstructing the economic recovery in Germany. Foreign demand is falling, private households forgo domestic consumption if it comes with infection risk, and investments are postponed. Assuming that the spread of the disease can be contained in short time, GDP growth in 2020 is expected to be 0.6% according to IWH spring economic forecast. Growth in East Germany is expected to be 0.9% and thus higher than in West Germany. If the number of new infections cannot be decreased in short time, we expect a recession in Germany.

Global economy slowly gains momentum – but Germany still stuck in a downturn
In 2020, the global economy is likely to benefit from the recent thaw in trade disputes. Germany’s manufacturing sector, however, will recover only slowly. “In 2020, the German economy will probably grow at a rate of 1.1%, and adjusted for the unusually high number of working days the growth rate will only be 0.7%”, says Oliver Holtemöller, head of the Department Macroeconomics and vice president at Halle Institute for Economic Research (IWH). With an estimated growth rate of 1.3%, production in East Germany will outpace total German production growth.

Abstract
Many questions about Brexit remain open. It is still possible that the UK and the European Union will not be able to agree on a withdrawal agreement. In this case a so-called hard Brexit (No-Deal Brexit) would happen. We have examined the short-term effects of a hard Brexit for the German economy. In a first step, effects via the trading channel are estimated based on an input-output analysis of international and sectoral links. The result is a loss of 0.3% relative to gross domestic product. This magnitude also results from the international Halle Economic Projection Model, which takes into account macroeconomic repercussions. A hard Brexit would, in addition to the trade barriers, mean significant uncertainty for firms and households. On the demand side, this has a negative impact on investment activity and private consumption. Taken alone, these effects amount to 0.1% of gross domestic product. Overall, German gross domestic product could be dampened by several tenths of a percentage point in the one to two years following a hard Brexit. The automotive industry would probably suffer most. However, recommendations for discretionary economic policy measures aimed at dampening short-term macroeconomic effects or at individual economic sectors cannot be derived from this. The automatic stabilizers are sufficient given the expected magnitude of the effects.
