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%.

Banking Deregulation and Consumption of Home Durables
H. Evren Damar, Ian Lange, Caitlin McKennie, Mirko Moro
IWH Discussion Papers,
No. 4,
2022
Abstract
We exploit the spatial and temporal variation of the staggered introduction of interstate banking deregulation across the U.S. to study the relationship between credit constraints and consumption of durables. Using the American Housing Survey from 1981 to 1989, we link the timing of these reforms with evidence of a credit expansion and household responses on many margins. We find evidence that low-income households are more likely to purchase new appliances after the deregulation. These durable goods allowed households to consume less natural gas and spend less time in domestic activities after the reforms.

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.

The Macroeconomics of Epidemics
Martin S. Eichenbaum, Sergio Rebelo, Mathias Trabandt
Review of Financial Studies,
No. 11,
2021
Abstract
We extend the canonical epidemiology model to study the interaction between economic decisions and epidemics. Our model implies that people cut back on consumption and work to reduce the chances of being infected. These decisions reduce the severity of the epidemic but exacerbate the size of the associated recession. The competitive equilibrium is not socially optimal because infected people do not fully internalize the effect of their economic decisions on the spread of the virus. In our benchmark model, the best simple containment policy increases the severity of the recession but saves roughly half a million lives in the United States.

Power Generation and Structural Change: Quantifying Economic Effects of the Coal Phase-out in Germany

Energy Economics,
2021
Abstract
In the fight against global warming, the reduction of greenhouse gas emissions is a major objective. In particular, a decrease in electricity generation by coal could contribute to reducing CO2 emissions. We study potential economic consequences of a coal phase-out in Germany, using a multi-region dynamic general equilibrium model. Four regional phase-out scenarios before the end of 2040 are simulated. We find that the worst case phase-out scenario would lead to an increase in the aggregate unemployment rate by about 0.13 [0.09 minimum; 0.18 maximum] percentage points from 2020 to 2040. The effect on regional unemployment rates varies between 0.18 [0.13; 0.22] and 1.07 [1.00; 1.13] percentage points in the lignite regions. A faster coal phase-out can lead to a faster recovery. The coal phase-out leads to migration from German lignite regions to German non-lignite regions and reduces the labour force in the lignite regions by 10,100 [6300; 12,300] people by 2040. A coal phase-out until 2035 is not worse in terms of welfare, consumption and employment compared to a coal-exit until 2040.

New wave of infections suspends economic recovery
The lockdown is being eased only slightly in Germany in March 2021, and gross domestic product (GDP) declines significantly in the first quarter of 2021. As vaccination campaigns progress and restrictions are gradually eased, a normalisation of household consumption patterns will likely boost the economy later during the year. The Halle Institute for Economic Research (IWH) forecasts that GDP will increase by 3.7% in 2021, following a decline of 4.9% in 2020. In East Germany, both the contraction and the rebound are much less pronounced.

During Corona, households are saving more – not for fear of unemployment but for lack of spending opportunities
During the Corona crisis, European households increased their savings dramatically. According to an analysis carried out by the Halle Institute for Economic Research (IWH), the increase in savings is largely due to the inability of households to consume in the face of government lockdown measures, rather than other factors such as economic uncertainty. IWH President Reint Gropp therefore sees potential for a significant catch-up effect in consumption as soon as the lockdown is lifted.

Why Are Households Saving so much During the Corona Recession?
Reint E. Gropp, William McShane
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.

Banking Deregulation and Household Consumption of Durables
H. Evren Damar, Ian Lange, Caitlin McKennie, Mirko Moro
Abstract
We exploit the spatial and temporal variation of the staggered introduction of interstate banking deregulation across the U.S. to study the relationship between credit constraints and consumption of durables. Using the American Housing Survey from 1981 to 1993, we link the timing of these reforms with evidence of a credit expansion and household responses on many margins. We find robust evidence that households are more likely to purchase new appliances and invest in home renovations and modifications after the deregulation. These durable goods allowed households to consume less electricity and spend less time in domestic activities after the reforms.

Epidemics in the Neoclassical and New Keynesian Models
Martin S. Eichenbaum, Sergio Rebelo, Mathias Trabandt
Abstract
We analyze the effects of an epidemic in three standard macroeconomic models. We find that the neoclassical model does not rationalize the positive comovement of consumption and investment observed in recessions associated with an epidemic. Introducing monopolistic competition into the neoclassical model remedies this shortcoming even when prices are completely flexible. Finally, sticky prices lead to a larger recession but do not fundamentally alter the predictions of the monopolistic competition model.
