Joint Economic Forecast 2/2022: Energy crisis: inflation, recession, welfare loss
The crisis on the gas markets is having a severe impact on the German economy. Soaring gas prices are drastically increasing energy costs, leading to a massive reduction of the purchasing power. Despite a decline in the second half of the year, gross domestic product is expected to expand by 1.4% this year. For the coming year, the institutes expect a contraction by 0.4%, followed by an increase of 1.9% in 2024.

Energy crisis in Germany
Dwindling gas supplies from Russia and soaring prices for gas and electricity are leading to massive real income losses and a recession in Europe and Germany. The Halle Institute for Economic Research (IWH) forecasts that German gross domestic product (GDP) will increase by 1.1% in 2022 and decrease by 1.4% in 2023. Consumer prices are expected to rise by 7.9% in 2022 and 9.5% in 2023.

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%.

Going Public and the Internal Organization of the Firm
Daniel Bias, Benjamin Lochner, Stefan Obernberger, Merih Sevilir
SSRN Working Paper,
May
2022
Abstract
We examine how firms adapt their organization when they go public. To conform with the requirements of public capital markets, we expect IPO firms to become more organized, making the firm more accountable and its human capital more easily replaceable. We find that IPO firms transform into a more hierarchical organization with smaller departments. Managerial oversight increases. Organizational functions dedicated to accounting, finance, information and communication, and human resources become much more prominent. Employee turnover is sizeable and directly related to changes in hierarchical layers. New hires are better educated, but younger and less experienced than incumbents, which reflects the staffing needs of a more hierarchical organization. Wage inequality increases as firms become more hierarchical. Overall, going public is associated with a comprehensive transformation of the firm's organization which becomes geared towards efficiently operating a public firm.

Regional effects of a recession in Germany triggered by an import stop for Russian gas
A halt in Russian gas deliveries would lead to a recession in the German economy. Not all regions would be equally affected: The Halle Institute for Economic Research (IWH) expects a significantly stronger slump in economic output in regions where the manufacturing sector has a large weight than elsewhere.

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.

Expectations, Infections, and Economic Activity
Martin S. Eichenbaum, Miguel Godinho de Matos, Francisco Lima, Sergio Rebelo, Mathias Trabandt
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.

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
Alessandro Sardone, Roberto Tamborini, Giuliana Passamani
Empirica,
February
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.
