European Firm Concentration and Aggregate Productivity

Abstract
This article derives a European Herfindahl-Hirschman concentration index from 15 micro-aggregated country datasets. In the last decade, European concentration rose due to a reallocation of economic activity towards large and concentrated industries. Over the same period, productivity gains from reallocation accounted for 50% of European productivity growth and markups stayed constant. Using country-industry variation, we show that changes in concentration are positively associated with changes in productivity and allocative efficiency. This holds across most sectors and countries and supports the notion that rising concentration in Europe reflects a more efficient market environment rather than weak competition and rising market power.

Economy in East Germany shrank less than in the West, but will have weaker momentum when pandemic disappears – Implications of the Joint Economic Forecast Spring 2021 and new data for East Germany
At 3%, the increase in gross domestic product in eastern Germany in 2021 is likely to be lower than in Germany as a whole (3.7%), as the slump due to the pandemic was smaller in 2020. In the course of the economic recovery in the second half of the year, the unemployment rate is expected to fall slightly.

Pandemic delays upswing – Demography slows growth
In their spring report, the leading economic research institutes forecast an increase in gross domestic product of 3.7% in the current year and 3.9% in 2022. The renewed shutdown is delaying the economic recovery, but as soon as the risks of infection, particularly from vaccination, have been averted, a strong recovery will begin. The economy is likely to return to normal output levels around the start of the coming year.

IWH Bankruptcy Update: German Bankruptcy Rates Remain Low in February
Bankruptcies statistics trended sideways at a low level in February 2021. Furthermore, the Halle Institute for Economic Research (IWH) does not anticipate higher bankruptcy rates in the coming months, despite Germany’s prolonged lockdown. These are the key findings of the IWH Bankruptcy Update, which provides monthly statistics on corporate bankruptcies in Germany.

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.

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.

High public deficit not only because of Corona - Medium-term options for action for the state

Konjunktur aktuell,
No. 4,
2020
Abstract
According to the IWH's medium-term projection, Germany's gross domestic product will grow by an average of ½% in price-adjusted terms in the years to 2025, which is 1 percentage point slower than in the period from 2013 to 2019. This is due not only to the sharp slump in 2020, but also to the fact that the labour force will decline noticeably. Government revenues will be expanding much more slowly than in previous years. Even after the pandemic crisis is overcome, the state budget is likely to have a structural deficit of about 2% relative to GDP if the legal framework remains unchanged, and the debt brake will continue to be violated. Consolidation measures to reduce this deficit ratio to ½ % would push production in Germany below the normal rate of capacity utilization. Simulations with the IWH fiscal policy model show that consolidation on the expenditure side would reduce production by less than consolidation on the revenue side. 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.

Changing Business Dynamism and Productivity: Shocks versus Responsiveness

American Economic Review,
No. 12,
2020
Abstract
The pace of job reallocation has declined in the United States in recent decades. We draw insight from canonical models of business dynamics in which reallocation can decline due to (i) lower dispersion of idiosyncratic shocks faced by businesses, or (ii) weaker marginal responsiveness of businesses to shocks. We show that shock dispersion has actually risen, while the responsiveness of business-level employment to productivity has weakened. Moreover, declining responsiveness can account for a significant fraction of the decline in the pace of job reallocation, and we find suggestive evidence this has been a drag on aggregate productivity.

Public Bank Guarantees and Allocative Efficiency
Reint E. Gropp, Andre Guettler, Vahid Saadi
Journal of Monetary Economics,
December
2020
Abstract
A natural experiment and matched bank/firm data are used to identify the effects of bank guarantees on allocative efficiency. We find that with guarantees in place unproductive firms receive larger loans, invest more, and maintain higher rates of sales and wage growth. Moreover, firms produce less productively. Firms also survive longer in banks’ portfolios and those that enter guaranteed banks’ portfolios are less profitable and productive. Finally, we observe fewer economy-wide firm exits and bankruptcy filings in the presence of guarantees. Overall, the results are consistent with the idea that guaranteed banks keep unproductive firms in business for too long.
