Konjunktur aktuell: Krieg treibt Energiepreise – Hohe Inflation belastet Konjunktur
Konjunktur aktuell,
No. 2,
2022
Abstract
Die Weltwirtschaft ist auch im Sommerhalbjahr verschiedenen schweren Belastungen ausgesetzt, die die Preise stark steigen lassen. Produktionsstilllegungen im Zuge der chinesischen Null-Covid-Strategie und der Angriff gegen die Ukraine heizen die Inflation weltweit an. Auch in Deutschland wird die konjunkturelle Entwicklung durch die mit dem Krieg verbundenen Preissteigerungen sowie unterbrochene Lieferketten schwer belastet. Die konjunkturellen Aussichten für den Sommer sind trüb. Das deutsche Bruttoinlandsprodukt wird im Jahr 2022 um 1,5% zunehmen. In Ostdeutschland liegt der Zuwachs bei 1%.

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

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.

IWH-Flash-Indikator I. Quartal und II. Quartal 2022

No. 1,
2022
Abstract
Nach der wirtschaftlichen Erholung im Sommerhalbjahr kam es im vierten Quartal 2021 wieder zu einem kräftigen Rückschlag. Das Bruttoinlandsprodukt sank um 0,7%, nachdem es im Vorquartal trotz der Probleme durch Lieferengpässe noch um 1,7% zugelegt hatte. Der Aufschwung wird wohl auch im ersten Quartal 2022 gedämpft sein, da die Infektionszahlen in Deutschland anders als in einigen anderen europäischen Ländern derzeit kräftig steigen und noch starke Pandemierestriktionen gelten. Auch die anhaltend kräftige Inflation dürfte Bremsspuren bei den wirtschaftlichen Aktivitäten hinterlassen. Insgesamt wird die Wirtschaft in Deutschland laut IWH-Flash-Indikator im ersten Quartal 2022 um 0,7% zurückgehen und im zweiten Quartal 2022 um 2,0% zulegen (vgl. Abbildung 1).

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.

Konjunktur aktuell: Deutsche Wirtschaft noch nicht immun gegen COVID 19 – Ausblick erneut eingetrübt
Konjunktur aktuell,
No. 4,
2021
Abstract
Ende 2021 belastet eine neue Infektionswelle die wirtschaftliche Aktivität in Europa. Die Stimmung im Dienstleistungsbereich ist im Herbst weltweit gestiegen, doch das Verarbeitende Gewerbe leidet weiter überall unter Knappheiten. Im Sommerhalbjahr 2022 gewinnt die Weltkonjunktur wieder etwas an Schwung, aber der ungewisse Fortgang der Pandemie bleibt ein Risiko. Pandemiewelle und Lieferengpässe lassen auch die deutsche Wirtschaft im Winter stagnieren. Der private Konsum wird ab Frühjahr deutlich zulegen, und die Konjunktur wird wieder kräftig in Schwung kommen. Das BIP wird 2022 um 3,5% zunehmen, nach 2,7% im Jahr 2021. Die Inflation dürfte nur langsam zurückgehen.

Production bottlenecks delay recovery
The German recovery made good progress over the summer 2021. However, bottlenecks in sea transport and the production of intermediate goods are weighing on world trade. The rise in raw material prices has prompted inflation rates to spike, and an increase in new infections is clouding the outlook again. A weak final quarter is therefore to be expected. The Halle Institute for Economic Research (IWH) forecasts that German gross domestic product (GDP) will increase by 2.2% in 2021 and 3.6% in 2022 (East Germany: 1.8% and 2.8%).

Conditional Macroeconomic Forecasts: Disagreement, Revisions and Forecast Errors
Alexander Glas, Katja Heinisch
IWH Discussion Papers,
No. 7,
2021
Abstract
Using data from the European Central Bank‘s Survey of Professional Forecasters, we analyse the role of ex-ante conditioning variables for macroeconomic forecasts. In particular, we test to which extent the heterogeneity, updating and ex-post performance of predictions for inflation, real GDP growth and the unemployment rate are related to assumptions about future oil prices, exchange rates, interest rates and wage growth. Our findings indicate that inflation forecasts are closely associated with oil price expectations, whereas expected interest rates are used primarily to predict output growth and unemployment. Expectations about exchange rates and wage growth also matter for macroeconomic forecasts, albeit less so than oil prices and interest rates. We show that survey participants can considerably improve forecast accuracy for macroeconomic outcomes by reducing prediction errors for external conditions. Our results contribute to a better understanding of the expectation formation process of experts.

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

Abstract
When referring to the inflation trends over the last decade, economists speak of "puzzles": a “missing disinflation” puzzle in the aftermath of the Great Recession, and a ”missing inflation” one in the years of recovery to nowadays. To this, a specific "excess deflation" puzzle may be added during the post-crisis depression in the Euro Zone. The standard Phillips Curve model, in this context, has failed as the basic tool to produce reliable forecasts of future price developments, leading many scholars to consider this instrument to be no more adequate. The purpose of this paper is to contribute to this literature through the development of a newly specified Phillips Curve model, in which the inflation-expectation component is rationally related to the business cycle. The model is tested with the Euro Zone data 1999-2019 showing that inflation turns out to be consistently determined by output gaps and and experts' survey-based forecast errors, and that the puzzles can be explained by the interplay between these two variables.
