30 Years after Reunification, Gross Domestic Product has Served its Purpose as an Indicator

Abstract
The comparison of living conditions in East and West Germany is often based on the gross domestic product per inhabitant. However, this measure is not a good welfare indicator in itself. It can be assumed that, measured by the gross domestic product per inhabitant, there will be no further significant equalisation of economic power in East and West Germany in the foreseeable future. This is because the age structure of East Germany, i.e. the ratio of employed persons to inhabitants, is less favourable than in the West. On the other hand, if one looks at important welfare indicators such as consumption opportunities, life expectancy, leisure time and income inequality, living conditions in East and West Germany are more similar than the gross domestic product per inhabitant suggests. In the debates on the catching-up process of East Germany, more emphasis should therefore be placed on labour productivity as a measure of economic strength and on welfare indicators as a measure of the equalisation of living conditions.

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

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.

High public deficits not only due to the pandemic – Medium-term options for fiscal policy
According to the IWH’s medium-term projection, Germany's gross domestic product will grow more slowly between 2020 and 2025 than before, not only because of the pandemic crisis, but also because the work force will decline. The resulting structural public deficits are, if the legal framework remains unchanged, likely to be higher than the debt brake allows. Consolidation measures, especially if they relate to government revenues, entail economic losses in the short term. “There is much to be said, also from a theoretical point of view, for not abolishing the debt brake, but for relaxing it to some extent,” says Oliver Holtemöller, head of the Department of Macroeconomics and vice president at Halle Institute for Economic Research (IWH).

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.

Economic slump in East Germany not as severe as in Germany as a whole ‒ Implications of the Joint Economic Forecast and new data for East Germany
The German economy started recovering quickly after the drastic pandemic-related slump in spring 2020. The recovery, however, loses much of its momentum in the second half of the year. The Joint Economic Forecast predicts that production levels seen before the crisis will not be reached again until the second half of 2021. In principle, the East German economy is following this pattern, although the economic slump is likely to be somewhat milder.

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.
