The Effects of Fiscal Policy in an Estimated DSGE Model – The Case of the German Stimulus Packages During the Great Recession
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.

IWH warnt vor neuer Bankenkrise
Die Corona-Rezession könnte das Aus für dutzende Banken bundesweit bedeuten – selbst wenn Deutschland die Wirtschaftskrise glimpflich übersteht. Gefährdet sind vor allem viele Sparkassen und Genossenschaftsbanken, zeigt eine Analyse des Leibniz-Instituts für Wirtschaftsforschung Halle (IWH). In den Bilanzen der betroffenen Geldinstitute stehen Kredite im dreistelligen Milliardenbereich. IWH-Präsident Gropp warnt vor einer möglichen hohen Zusatzlast für die ohnehin geschwächte Realwirtschaft.
What Drives the Commodity-Sovereign-Risk-Dependence in Emerging Market Economies?
Using daily data for 34 emerging markets in the period 1994-2016, we find robust evidence that higher export commodity prices are associated with higher sovereign bond returns (indicating lower sovereign risk). The economic effect is especially pronounced for heavy commodity exporters. Examining the drivers, we find, first, that commodity-dependence is higher for countries that export large volumes of volatile commodities and that the effect increases in times of recessions, high inflation, and expansionary U.S. monetary policy. Second, the importance of raw material prices for sovereign financing can likely be mitigated if a country improves institutions and tax systems, attracts FDI inflows, invests in manufacturing, machinery and infrastructure, builds up reserve assets and opens capital and trade accounts. Third, the concentration of commodities within a country’s portfolio, its government indebtedness or amount of received development assistance appear to be only of secondary importance for commodity-dependence.
Resolving the Missing Deflation and Inflation Puzzles
VOX, CEPR Policy Portal,
The alleged breakdown of the Phillips curve has left monetary policy researchers and central bankers wondering if we need to develop completely new models for price and wage determination. This column argues that a relatively small alteration of the standard New Keynesian model, combined with using the nonlinear instead of the linearised solution, is sufficient to resolve the two puzzles – the ‘missing deflation’ during the recession and the ‘missing inflation’ during the recovery – underlying the supposed breakdown.
Structural Stability of the Research & Development Sector in European Economies Despite the Economic Crisis
Journal of Evolutionary Economics,
When an external shock such as the economic crisis in 2008/2009 occurs, the interconnectedness of sectors can be affected. This paper investigates whether the R&D sector experienced changes in its sectoral integration through the recession. Based on an input-output analysis, it can be shown that the linkages of the R&D sector with other sectors remain stable. In some countries, the inter-sectoral integration becomes even stronger. Policy makers can be encouraged to use public R&D spending as a means of fiscal policy against an economic crisis.
What Drives Discretion in Bank Lending? Some Evidence and a Link to Private Information
Journal of Banking & Finance,
We assess the extent to which discretion, unexplained variations in the terms of a loan contract, has varied across time and lending institutions and show that part of this discretion is due to private information that lenders have on their borrowers. We find that discretion is lower for secured loans and loans granted by a larger group of lenders, and is larger when the lenders are larger and more profitable. Over time, discretion is also lower around recessions although the private information content is higher. The results suggest that bank discretionary and private information acquisition behavior may be important features of the credit cycle.
