Expectations, Infections, and Economic Activity

Abstract
The Covid epidemic had a large impact on economic activity. In contrast, the dramatic decline in mortality from infectious diseases over the past 120 years had a small economic impact. We argue that people's response to successive Covid waves helps reconcile these two findings. Our analysis uses a unique administrative data set with anonymized monthly expenditures at the individual level that covers the first three Covid waves. Consumer expenditures fell by about the same amount in the first and third waves, even though the risk of getting infected was larger in the third wave. We find that people had pessimistic prior beliefs about the case-fatality rates that converged over time to the true case-fatality rates. Using a model where Covid is endemic, we show that the impact of Covid is small when people know the true case-fatality rate but large when people have empirically-plausible pessimistic prior beliefs about the case-fatality rate. These results reconcile the large economic impact of Covid with the small effect of the secular decline in mortality from infectious diseases estimated in the literature.

Firm-specific Forecast Errors and Asymmetric Investment Propensity
Manuel Buchholz, Lena Tonzer, Julian Berner
Economic Inquiry,
No. 2,
2022
Abstract
This paper analyzes how firm-specific forecast errors derived from survey data of German manufacturing firms over 2007–2011 relate to firms' investment propensity. Our findings reveal that asymmetries arise depending on the size and direction of the forecast error. The investment propensity declines if the realized situation is worse than expected. However, firms do not adjust investment if the realized situation is better than expected suggesting that the uncertainty component of the forecast error counteracts good surprises of unexpectedly favorable business conditions. This asymmetric mechanism can be one explanation behind slow recovery following crises.

From Pandemic to Energy Crisis: Economy and Politics under Permanent Stress
The German economy is steering through difficult waters and faces the highest inflation rates in decades. In their spring report, the leading German economic research institutes revise their outlook for this year significantly downward. The recovery from the COVID-19 crisis is slowing down as a result of the war in Ukraine, but remains on track. The institutes expect GDP to increase by 2.7% and 3.1% in 2022 and 2023 respectively. In the event of an immediate interruption to Russian gas supplies, a total of 220 billion euros in German economic output would be at risk in both years.

Inflation Puzzles, the Phillips Curve and Output Expectations: New Perspectives from the Euro Zone

2022
Abstract
Confidence in the Phillips Curve (PC) as predictor of inflation developments along the business cycle has been shaken by recent “inflation puzzles” in advanced countries, such as the “missing disinflation” in the aftermath of the Great Recession and the “missing inflation” in the years of recovery, to which the Euro-Zone “excess deflation” during the post-crisis depression may be added. This paper proposes a newly specified Phillips Curve model, in which expected inflation, instead of being treated as an exogenous explanatory variable of actual inflation, is endogenized. The idea is simply that if the PC is used to foresee inflation, then its expectational component should in some way be the result of agents using the PC itself. As a consequence, the truly independent explanatory variables of inflation turn out to be the output gaps and the related forecast errors by agents, with notable empirical consequences. The model is tested with the Euro-Zone data 1999–2019 showing that it may provide a consistent explanation of the “inflation puzzles” by disentangling the structural component from the expectational effects of the PC.

Stress-ridden Finance and Growth Losses: Does Financial Development Break the Link?

Abstract
Does financial development shield countries from the pass-through of financial shocks to real outcomes? We evaluate this question by characterising the probability density of expected GDP growth conditional on financial stability indicators in a panel of 28 countries. Our robust results unveil a non-linear nexus between financial stability and expected GDP growth, depending on countries’ degree of financial development. While both domestic and global financial factors affect expected growth, the effect of global factors is moderated by financial development. This result highlights a previously unexplored channel trough which financial development can break the link between financial (in)stability and GDP growth.

Investment, output gap, and public finances in the medium term: Implications of the Second Supplementary Budget 2021
With the Second Supplementary Budget 2021, the German government plans to allocate a reserve of 60 billion euros to the Energy and Climate Fund. This additional spending is also meant to reduce the macroeconomic follow-up costs of the pandemic. According to the IWH’s medium-term projection, the expenditure is expected to increase output by about 0.5% at the peak of its impact in 2024. “While this macroeconomic effect is welcome, the additional investment will by no means compensate for the lack of investment activity since the beginning of the pandemic,” says Oliver Holtemöller, head of the Department Macroeconomics and vice president at Halle Institute for Economic Research (IWH). Moreover, the supplementary budget is likely to reduce confidence in the reliability of the debt brake.

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.

Cryptocurrency Volatility Markets
Fabian Wöbbeking
Digital Finance,
No. 3,
2021
Abstract
By computing a volatility index (CVX) from cryptocurrency option prices, we analyze this market’s expectation of future volatility. Our method addresses the challenging liquidity environment of this young asset class and allows us to extract stable market implied volatilities. Two alternative methods are considered to compute volatilities from granular intra-day cryptocurrency options data, which spans over the COVID-19 pandemic period. CVX data therefore capture ‘normal’ market dynamics as well as distress and recovery periods. The methods yield two cointegrated index series, where the corresponding error correction model can be used as an indicator for market implied tail-risk. Comparing our CVX to existing volatility benchmarks for traditional asset classes, such as VIX (equity) or GVX (gold), confirms that cryptocurrency volatility dynamics are often disconnected from traditional markets, yet, share common shocks.

Crisis is gradually being overcome – align actions to lower growth
The Corona pandemic still shapes the economic situation in Germany. A complete normalisation of contact-intensive activities is not to be expected in the short term. In addition, supply bottlenecks are hampering manufacturing for the time being. The German economy will reach normal capacity utilisation in the course of 2022. In their autumn report, the leading economic research institutes forecast that Gross Domestic Product (GDP) will rise by 2.4% in 2021 and by 4.8% in 2022.
