Economic mobility likely to increase significantly after relaxation – but also number of COVID-19 cases
The relaxation of Corona containment measures from the beginning of March 2021 lead to a significant increase in economic mobility and thus also in personal contacts in Germany. Estimates suggest that the recent relaxations increase economic mobility by more than ten percentage points and the number of new infections and deaths in Germany by 25%. Because both continued lockdowns and relaxations carry significant negative consequences, it is even more important to enable further relaxations through better testing and quarantine strategies and by increasing the pace of vaccination without putting people's health at risk.

Economic Mobility Likely to Increase Significantly after Relaxation – but also Number of COVID-19 Cases
Oliver Holtemöller, Malte Rieth
IWH Policy Notes,
No. 3,
2021
Abstract
In Germany, measures to contain the coronavirus were relaxed in some areas at the beginning of March; in many places, for example, the restrictions on private and public gatherings were eased, and retail stores are increasingly able to receive customers again. The aim of these decisions is to allow for more economic mobility and personal contact between people. However, the frequency of contact is a major factor influencing the rate at which the coronavirus spreads, especially since the relaxations have so far not been accompanied by a systematic testing strategy; and vaccination progress has so far also fallen short of expectations. Estimates based on a model of the relationship between containment measures (Oxford COVID-19 Government Response Tracker, Stringency Index), economic mobility (Google Mobility Data), new corona infections, and deaths with data from 44 countries suggest that the recent relaxations increase economic mobility by ten percentage points and the number of new infections and deaths in Germany by 25%. Because both continued lockdown and relaxations have significant negative consequences, it is even more important to enable further relaxations through better testing and quarantine strategies and by increasing the pace of vaccination without putting people's health at risk.

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.

What Does Peer-to-Peer Lending Evidence Say About the Risk-taking Channel of Monetary Policy?
Yiping Huang, Xiang Li, Chu Wang
Journal of Corporate Finance,
2021
Abstract
This paper uses loan application-level data from a peer-to-peer lending platform to study the risk-taking channel of monetary policy. By employing a direct ex-ante measure of risk-taking and estimating the simultaneous equations of loan approval and loan amount, we provide evidence of monetary policy's impact on a nonbank financial institution's risk-taking. We find that the search-for-yield is the main driving force of the risk-taking effect, while we do not observe consistent findings of risk-shifting from the liquidity change. Monetary policy easing is associated with a higher probability of granting loans to risky borrowers and greater riskiness of credit allocation. However, these changes do not necessarily relate to a larger loan amount on average.

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.

Optimizing Policymakers’ Loss Functions in Crisis Prediction: Before, Within or After?
Peter Sarlin, Gregor von Schweinitz
Macroeconomic Dynamics,
No. 1,
2021
Abstract
Early-warning models most commonly optimize signaling thresholds on crisis probabilities. The expost threshold optimization is based upon a loss function accounting for preferences between forecast errors, but comes with two crucial drawbacks: unstable thresholds in recursive estimations and an in-sample overfit at the expense of out-of-sample performance. We propose two alternatives for threshold setting: (i) including preferences in the estimation itself and (ii) setting thresholds ex-ante according to preferences only. Given probabilistic model output, it is intuitive that a decision rule is independent of the data or model specification, as thresholds on probabilities represent a willingness to issue a false alarm vis-à-vis missing a crisis. We provide simulated and real-world evidence that this simplification results in stable thresholds and improves out-of-sample performance. Our solution is not restricted to binary-choice models, but directly transferable to the signaling approach and all probabilistic early-warning models.

Involuntary Unemployment and the Business Cycle
Lawrence J. Christiano, Mathias Trabandt, Karl Walentin
Review of Economic Dynamics,
January
2021
Abstract
Can a model with limited labor market insurance explain standard macro and labor market data jointly? We construct a monetary model in which: i) the unemployed are worse off than the employed, i.e. unemployment is involuntary and ii) the labor force participation rate varies with the business cycle. To illustrate key features of our model, we start with the simplest possible framework. We then integrate the model into a medium-sized DSGE model and show that the resulting model does as well as existing models at accounting for the response of standard macroeconomic variables to monetary policy shocks and two technology shocks. In addition, the model does well at accounting for the response of the labor force and unemployment rate to these three shocks.

Much more bankruptcies expected than currently observed in Germany
In a recession, the number of bankruptcies usually increases with some delay. However, despite the corona crisis, the number of bankruptcies in Germany is lower than predicted based on the long-term trend. The state aid packages and the suspension of the insolvency rules have led to fewer bankruptcies than expected. The Halle Institute for Economic Research (IWH) has estimated how many bankruptcies would actually have been likely to occur by industry because of the corona recession if the typical economic pattern had been in place. The results indicate that after the end of the state aid and exception rules bankruptcies are likely to pick up.

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.

Switching to Good Policy? The Case of Central and Eastern European Inflation Targeters
Andrej Drygalla
Macroeconomic Dynamics,
No. 8,
2020
Abstract
The paper analyzes how actual monetary policy changed following the official adoption of inflation targeting in the Czech Republic, Hungary, and Poland and how it affected the volatilities of important macroeconomic variables in the years thereafter. To disentangle the effects of the policy shift from exogenous changes in the volatilities of these variables, a Markov-switching dynamic stochastic general equilibrium model is estimated that allows for regime switches in the policy parameters and the volatilities of shocks hitting the economies. Whereas estimation results reveal periods of high and low volatility for all three economies, the presence of different policy regimes is supported by the underlying data for the Czech Republic and Poland, only. In both economies, monetary policy switched from weak and unsystematic to strong and systematic responses to inflation dynamics. Simulation results suggest that the policy shifts of both central banks successfully reduced inflation volatility in the following years. The observed reduction in output volatility, on the other hand, is attributed more to a reduction in the size of external shocks.
