Nr. 4,

Abstract
Nach der Mittelfristprojektion des IWH wird das Bruttoinlandsprodukt in Deutschland in den Jahren bis 2025 preisbereinigt um durchschnittlich ½% wachsen, und damit einen Prozentpunkt langsamer als im Zeitraum von 2013 bis 2019. Dies ist nicht nur auf den starken Einbruch im Jahr 2020 zurückzuführen, sondern auch darauf, dass die Erwerbsbevölkerung spürbar zurückgehen wird. Die Staatseinnahmen expandieren deutlich langsamer als in den vergangenen Jahren. Auch nach Überwindung der Pandemiekrise dürfte der Staatshaushalt im Fall unveränderter gesetzlicher Rahmenbedingungen ein strukturelles Defizit von etwa 2% relativ zum Bruttoinlandsprodukt aufweisen, und die Schuldenbremse würde weiter verletzt. Konsolidierungsmaßnahmen zur Rückführung dieser Defizitquote auf ½% würden die Produktion in Deutschland unter die Normalauslastung drücken. Mit Hilfe des finanzpolitischen Simulationsmodells des IWH kann gezeigt werden, dass dabei eine ausgabenseitige Konsolidierung die Produktion weniger belastet als eine einnahmenseitige. Es spricht, auch aus theoretischer Sicht, viel dafür, die Schuldenbremse zwar nicht abzuschaffen, aber ein Stück weit zu lockern.

Drawing Conclusions from Structural Vector Autoregressions Identified on the Basis of Sign Restrictions
Christiane Baumeister, James D. Hamilton
Journal of International Money and Finance,
December
2020
Abstract
This paper discusses the problems associated with using information about the signs of certain magnitudes as a basis for drawing structural conclusions in vector autoregressions. We also review available tools to solve these problems. For illustration we use Dahlhaus and Vasishtha’s (2019) study of the effects of a U.S. monetary contraction on capital flows to emerging markets. We explain why sign restrictions alone are not enough to allow us to answer the question and suggest alternative approaches that could be used.

Financial Technologies and the Effectiveness of Monetary Policy Transmission
Iftekhar Hasan, Boreum Kwak, Xiang Li
Abstract
This study investigates whether and how financial technologies (FinTech) influence the effectiveness of monetary policy transmission. We use an interacted panel vector autoregression model to explore how the effects of monetary policy shocks change with regional-level FinTech adoption. Results indicate that FinTech adoption generally mitigates the transmission of monetary policy to real GDP, consumer prices, bank loans, and housing prices, with the most significant impact observed in the weakened transmission to bank loan growth. The relaxed financial constraints, regulatory arbitrage, and intensified competition are the possible mechanisms underlying the mitigated transmission.

Sovereign Default Risk, Macroeconomic Fluctuations and Monetary-Fiscal Stabilisation
Markus Kirchner, Malte Rieth
IWH Discussion Papers,
Nr. 22,
2020
Abstract
This paper examines the role of sovereign default beliefs for macroeconomic fluctuations and stabilisation policy in a small open economy where fiscal solvency is a critical problem. We set up and estimate a DSGE model on Turkish data and show that accounting for sovereign risk significantly improves the fit of the model through an endogenous amplication between default beliefs, exchange rate and inflation movements. We then use the estimated model to study the implications of sovereign risk for stability, fiscal and monetary policy, and their interaction. We find that a relatively strong fiscal feedback from deficits to taxes, some exchange rate targeting, or a monetary response to default premia are more effective and efficient stabilisation tools than hawkish inflation targeting.

Marginal Returns to Talent for Material Risk Takers in Banking
Moritz Stieglitz, Konstantin Wagner
IWH Discussion Papers,
Nr. 20,
2020
Abstract
Economies of scale can explain compensation differentials over time, across firms of different size, different hierarchy-levels, and different industries. Consequently, the most talented individuals tend to match with the largest firms in industries where marginal returns to their talent are greatest. We explore a new dimension of this size-pay nexus by showing that marginal returns also differ across activities within firms and industries. Using hand-collected data on managers in European banks well below the level of executive directors, we find that the size-pay nexus is strongest for investment banking business units and for banks with a market-based business model. Thus, managerial compensation is most sensitive to size increases for activities that can easily be scaled up.

Epidemics in the Neoclassical and New Keynesian Models
Martin S. Eichenbaum, Sergio Rebelo, Mathias Trabandt
Abstract
We analyze the effects of an epidemic in three standard macroeconomic models. We find that the neoclassical model does not rationalize the positive comovement of consumption and investment observed in recessions associated with an epidemic. Introducing monopolistic competition into the neoclassical model remedies this shortcoming even when prices are completely flexible. Finally, sticky prices lead to a larger recession but do not fundamentally alter the predictions of the monopolistic competition model.

Dynamic Equity Slope

Nr. 21,

Abstract
The term structure of equity and its cyclicality are key to understand the risks drivingequilibrium asset prices. We propose a general equilibrium model that jointly explainsfour important features of the term structure of equity: (i) a negative unconditionalterm premium, (ii) countercyclical term premia, (iii) procyclical equity yields, and (iv)premia to value and growth claims respectively increasing and decreasing with thehorizon. The economic mechanism hinges on the interaction between heteroskedasticlong-run growth — which helps price long-term cash flows and leads to countercyclicalrisk premia — and homoskedastic short-term shocks in the presence of limited marketparticipation — which produce sizeable risk premia to short-term cash flows. The slopedynamics hold irrespective of the sign of its unconditional average. We provide empirical support to our model assumptions and predictions.

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,
Nr. 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.

Employment Effects of Introducing a Minimum Wage: The Case of Germany
Oliver Holtemöller, Felix Pohle
Economic Modelling,
July
2020
Abstract
Income inequality has been a major concern of economic policy makers for several years. Can minimum wages help to mitigate inequality? In 2015, the German government introduced a nationwide statutory minimum wage to reduce income inequality by improving the labour income of low-wage employees. However, the employment effects of wage increases depend on time and region specific conditions and, hence, they cannot be known in advance. Because negative employment effects may offset the income gains for low-wage employees, it is important to evaluate minimum-wage policies empirically. We estimate the employment effects of the German minimum-wage introduction using panel regressions on the state-industry-level. We find a robust negative effect of the minimum wage on marginal and a robust positive effect on regular employment. In terms of the number of jobs, our results imply a negative overall effect. Hence, low-wage employees who are still employed are better off at the expense of those who have lost their jobs due to the minimum wage.

Citizen Science jenseits von MINT – Bürgerforschung in den Geistes‐ und Sozialwissenschaften
Claudia Göbel, Justus Henke, Sylvi Mauermeister, Verena Plümpe
HoF Arbeitsberichte Heft 114,
2020
Abstract
Citizen Science im Bereich der Geistes‐ und Sozialwissenschaften – Social Citizen Science (SCS) – ist ein bislang wenig untersuchter Teilbereich bürgerwissenschaftlicher Aktivitäten. Eine ihrer Besonderheiten ist, dass sie gerade aufgrund ihrer Nähe zur Alltagswelt schwer objektivierbare Beobachtungen verarbeitet. Fragen der Sicherstellung wissenschaftlicher Qualität und der Partizipationsfähigkeit stellen sich mithin auf andere Weise als in naturwissenschaftlich geprägter Citizen Science. Die vorliegende Studie legt hierzu erstmals Daten vor. Es zeigt sich eine große Diversität empirischer Zugänge und Traditionen in SCS. Hervorzuheben ist, dass sich unter den SCS‐Aktivitäten gleichermaßen inner‐ als auch außerakademisch initiierte und geleitete befinden. Damit ist die eingeladene Partizipation durch Wissenschaftseinrichtungen nicht als das allgemeine Referenzmodell für SCS anzusehen, sondern gleichwertig mit uneingeladener Partizipation aus der Zivilgesellschaft heraus. Für SCS‐Vorhaben geht es daher weniger um die Herstellung von „Partizipationsfähigkeit“ von Laien an Forschungsprozessen, sondern vielmehr von „Zusammenarbeitsfähigkeit“ diverser inner‐ und außerakademischer Akteure.
