IWH-Tarif-Check: Aktuelle Tarifabschlüsse bedeuten Reallohnverluste 2024
Oliver Holtemöller, Birgit Schultz
IWH-Tarif-Check,
No. 2,
2023
Abstract
*** Vergleich der Tariflohnabschlüsse von Chemischer Industrie, Deutscher Post, Metall- und Elektroindustrie und öffentlichem Dienst von Bund und Kommunen *** Die hohe Verbraucherpreisinflation hat den Lohndruck bei den Tarifverhandlungen stark erhöht. Das Leibniz-Institut für Wirtschaftsforschung Halle (IWH) hat die Lohnabschlüsse für vier ausgewählte Branchen, die sich im vergangenen Halbjahr auf Neuabschlüsse geeinigt haben, verglichen. Dabei zeigen sich hohe nominale Lohnsteigerungen. Insbesondere die Inflationsausgleichsprämie, die in allen vier Branchen bis zur maximalen Höhe von 3000 Euro vereinbart wurde, lässt die Bruttolöhne kräftig steigen. In der Chemischen Industrie, in der es bereits in der vergangenen Lohnrunde eine hohe Einmalzahlung gab, füllt die vereinbarte Inflationsausgleichszahlung diese Lücke.

Trust, Politics and Post-IPO Performance: SOEs vs. the Private Sector
Bill Francis, Iftekhar Hasan, Xian Sun, Mingming Zhou
Economic and Political Studies,
No. 3,
2022
Abstract
This paper empirically investigates the role of social trust in the long-term performance of the initial public offerings (IPOs) in China, controlling for the formal institutional environment. We find that privately owned or smaller IPO firms experience significantly better post-IPO performance when they are incorporated in regions with more social trust. The state-owned and bigger IPO firms, on the other hand, experience better long-term post-IPO performance when they are incorporated in regions with stronger formal institutions (e.g. court enforcement and contract holding). Political pluralism turns out to benefit all IPOs in the long term. In addition, our evidence shows that stronger social trust substitutes for the quality of court enforcement but complements the role of contract holding. These results are robust after controlling for alternative definitions of ownership, outliers, non-linear effects of institutions, and the potential endogeneity of institutions in the model.

East German economy less affected by supply bottlenecks than German economy as a whole, but lower vaccination rates pose risks – Implications of the Joint Economic Forecast Autumn 2021 and of Länder data from recent publications of the Federal Statisti
Supply bottlenecks affect production in the manufacturing sector in East Germany somewhat less than in Germany as a whole. With 1.8%, the increase in Gross Domestic Product in eastern Germany in 2021 therefore is likely to be lower than in Germany as a whole (2.4%); this gap is likely to enlarge in 2022, when supply bottlenecks hamper less (East Germany: 3.6%, Germany 4.8%).

The Effects of Fiscal Policy in an Estimated DSGE Model – The Case of the German Stimulus Packages During the Great Recession
Andrej Drygalla, Oliver Holtemöller, Konstantin Kiesel
Macroeconomic Dynamics,
No. 6,
2020
Abstract
In this paper, we analyze the effects of the stimulus packages adopted by the German government during the Great Recession. We employ a standard medium-scale dynamic stochastic general equilibrium (DSGE) model extended by non-optimizing households and a detailed fiscal sector. In particular, the dynamics of spending and revenue variables are modeled as feedback rules with respect to the cyclical components of output, hours worked and private investment. Based on the estimated rules, fiscal shocks are identified. According to the results, fiscal policy, in particular public consumption, investment, and transfers prevented a sharper and prolonged decline of German output at the beginning of the Great Recession, suggesting a timely response of fiscal policy. The overall effects, however, are small when compared to other domestic and international shocks that contributed to the economic downturn. Our overall findings are not sensitive to considering fiscal foresight.

Identifying Cooperation for Innovation―a Comparison of Data Sources
Michael Fritsch, Mirko Titze, Matthias Piontek
Industry and Innovation,
No. 6,
2020
Abstract
The value of social network analysis is critically dependent on the comprehensive and reliable identification of actors and their relationships. We compare regional knowledge networks based on different types of data sources, namely, co-patents, co-publications, and publicly subsidized collaborative R&D projects. Moreover, by combining these three data sources, we construct a multilayer network that provides a comprehensive picture of intraregional interactions. By comparing the networks based on the data sources, we address the problems of coverage and selection bias. We observe that using only one data source leads to a severe underestimation of regional knowledge interactions, especially those of private sector firms and independent researchers.
