Abstract
Nach der Mittelfristprojektion des IWH wird das Bruttoinlandsprodukt in Deutschland in den Jahren von 2017 bis 2022 um durchschnittlich 1½% wachsen; das nominale Bruttoinlandsprodukt wird um durchschnittlich 3½% zunehmen. Aufgrund der starken konjunkturellen Dynamik wird der Staat hohe Haushaltsüberschüsse erzielen. Die gute Finanzlage des Staates bietet einer neuen Bundesregierung große finanzpolitische Handlungsspielräume. Aufbauend auf der Mittelfristprojektion des IWH und mit Hilfe eines makroökonometrischen Modells werden die Wirkungen verschiedener finanzpolitischer Maßnahmen auf diverse makroökonomische Größen analysiert. Im Ergebnis zeigt sich, dass der Multiplikator bei ausgabeseitigen expansiven finanzpolitischen Maßnahmen im Simulationszeitraum größer wäre als bei einnahmeseitigen. In der derzeitigen konjunkturellen Lage und aufgrund der im internationalen Vergleich immer noch hohen Abgabenbelastung des Faktors Arbeit wären einnahmeseitige Maßnahmen insgesamt besser geeignet, die Haushaltsüberschüsse abzubauen.

The medium-term economic development in Germany from 2017 to 2022 and opportunities for fiscal policies of a new federal government
Due to the cyclical upswing in Germany, in case of unaltered legislation, the general government would achieve considerable budget surpluses in the years ahead. As a consequence, there is large fiscal scope for a new federal government. With the fiscal policy simulation model of the Halle Institute for Economic Research (IWH) – Member of the Leibniz Association, the macroeconomic effects of various fiscal policy measures are analysed. The results show that additional government expenditures, like the expansion of social benefits, do have a stronger effect on GDP than revenue cuts, like for instance tax reliefs. „Due to the already high capacity utilisation, revenue cuts seem to be advantageous from a business cycle perspective. Moreover, a reduction of the high taxes and charges on labour would, in contrast to an expansion of social benefits, have a positive effect on potential output“, says Oliver Holtemöller, head of the Department of Macroeconomics and IWH vice president.

Das Growth Accounting Model wird angewandt, um den Einfluss der Faktoren Arbeit und Kapital sowie des technischen Fortschritts auf das Wachstum des Bruttoinlandsprodukts der DDR in den verschiedenen Perioden abzuschätzen. Hauptergebnis ist die Erkenntnis, dass das Zentralplanungsmodell an der Modernisierung scheiterte und nur während der Wirtschaftsreformen in der zweiten Hälfte der Sechziger die totale Faktorproduktivität den entscheidenden Einfluss auf das Wirtschaftswachstum ausübte.

Macro-Financial Modelling of the Singapore Economy: a GVAR Approach
Alessandro Galesi, Filippo di Mauro
Monetary Authority of Singapore Macroeconomic Review,
October
2017
Abstract
Globalisation has greatly increased the degree of interdependence across countries. Macroeconomic policy must therefore take a global perspective, particularly in the case of small open economies such as Singapore. From a modeller’s point of view, this requires considering many countries, regions and markets, as well as multiple channels of transmission, including trade and financial linkages. Cross-country interdependencies are increasingly reflected in the effects of global shocks, to oil or food prices for example, as well as technology and policy uncertainty spillovers.

The German economy: Growing strongly
In the summer of 2017, the upswing in Germany continues. „For this year, we forecast gross domestic product to expand by 1.9%, as it did in 2016, and for 2018 by 2.0%” says Oliver Holtemöller, head of the Department Macroeconomics and IWH vice president.

U.S. Monetary-Fiscal Regime Changes in the Presence of Endogenous Feedback in Policy Rules
Yoosoon Chang, Boreum Kwak
Abstract
We investigate U.S. monetary and fiscal policy regime interactions in a model, where regimes are determined by latent autoregressive policy factors with endogenous feedback. Policy regimes interact strongly: Shocks that switch one policy from active to passive tend to induce the other policy to switch from passive to active, consistently with existence of a unique equilibrium, though both policies are active and government debt grows rapidly in some periods. We observe relatively strong interactions between monetary and fiscal policy regimes after the recent financial crisis. Finally, latent policy regime factors exhibit patterns of correlation with macroeconomic time series, suggesting that policy regime change is endogenous.

Should Forecasters Use Real-time Data to Evaluate Leading Indicator Models for GDP Prediction? German Evidence
Katja Heinisch, Rolf Scheufele
Abstract
In this paper we investigate whether differences exist among forecasts using real-time or latest-available data to predict gross domestic product (GDP). We employ mixed-frequency models and real-time data to reassess the role of survey data relative to industrial production and orders in Germany. Although we find evidence that forecast characteristics based on real-time and final data releases differ, we also observe minimal impacts on the relative forecasting performance of indicator models. However, when obtaining the optimal combination of soft and hard data, the use of final release data may understate the role of survey information.

The Macroeconomic Risks of Undesirably Low Inflation
Jonas Arias, Christopher J. Erceg, Mathias Trabandt
European Economic Review,
2016
Abstract
This paper investigates the macroeconomic risks associated with undesirably low inflation using a medium-sized New Keynesian model. We consider different causes of persistently low inflation, including a downward shift in long-run inflation expectations, a fall in nominal wage growth, and a favorable supply-side shock. We show that the macroeconomic effects of persistently low inflation depend crucially on its underlying cause, as well as on the extent to which monetary policy is constrained by the zero lower bound. Finally, we discuss policy options to mitigate these effects.

Unemployment and Business Cycles

Econometrica,
No. 4,

Abstract
We develop and estimate a general equilibrium search and matching model that accounts for key business cycle properties of macroeconomic aggregates, including labor market variables. In sharp contrast to leading New Keynesian models, we do not impose wage inertia. Instead we derive wage inertia from our specification of how firms and workers negotiate wages. Our model outperforms a variant of the standard New Keynesian Calvo sticky wage model. According to our estimated model, there is a critical interaction between the degree of price stickiness, monetary policy, and the duration of an increase in unemployment benefits.
