Interest Benefits from the Debt Crisis to the German Budget: Updated Calculations
In an updated calculation, IWH researchers could provide further evidence that interest benefits to the German budget arise indeed also from the “flight-to-safety-effect” and are not just effects from the low interest environment more generally. With a refined methodology they obtain interest savings to the German budget of just under 90 billion Euro.

Monetary Policy and the Transaction Role of Money in the US
Alexander Kriwoluzky, Christian A. Stoltenberg
Economic Journal,
No. 587,
2015
Abstract
The declining importance of money in transactions can explain the well-known fact that US interest rate policy was passive in the pre-Volcker period and active after 1982. We generalise a standard cashless new Keynesian model (Woodford, 2003) by incorporating an explicit transaction role for money. In the pre-Volcker period, we estimate that money did play an important role and determinacy required a passive interest rate policy. However, after 1982, money no longer played an important role in facilitating transactions. Correspondingly, the conventional view prevails and an active policy ensured equilibrium determinacy.

Germany Benefited Substantially from the Greek Crisis
The balanced budget in Germany is largely the result of lower interest payments due to the European debt crisis. Research from the Halle Institute for Economic Research (IWH) – Member of the Leibniz Association shows that the debt crisis resulted in a reduction in German bund rates of about 300 basis points (BP), yielding interest savings of more than EUR 100 billion (or more than 3% of gross domestic product, GDP) during the period 2010 to 2015. A significant part of this reduction is directly attributable to the Greek crisis. When discussing the costs to the German tax payer of saving Greece, these benefits should not be overlooked, as they tend to be larger than the expenses, even in a scenario where Greece does not repay any of its debts.

Monetary Policy under the Microscope: Intra-bank Transmission of Asset Purchase Programs of the ECB
L. Cycon, Michael Koetter
IWH Discussion Papers,
No. 9,
2015
Abstract
With a unique loan portfolio maintained by a top-20 universal bank in Germany, this study tests whether unconventional monetary policy by the European Central Bank (ECB) reduced corporate borrowing costs. We decompose corporate lending rates into refinancing costs, as determined by money markets, and markups that the bank is able to charge its customers in regional markets. This decomposition reveals how banks transmit monetary policy within their organizations. To identify policy effects on loan rate components, we exploit the co-existence of eurozone-wide security purchase programs and regional fiscal policies at the district level. ECB purchase programs reduced refinancing costs significantly, even in an economy not specifically targeted for sovereign debt stress relief, but not loan rates themselves. However, asset purchases mitigated those loan price hikes due to additional credit demand stimulated by regional tax policy and enabled the bank to realize larger economic margins.

Gemeinschaftsdiagnose: Kräftiger Aufschwung dank günstigem Öl und schwachem Euro
Oliver Holtemöller, Ferdinand Fichtner, Roland Döhrn, Timo Wollmershäuser
Wirtschaftsdienst,
No. 5,
2015
Abstract
In ihrem Frühjahrsgutachten prognostizieren die an der Gemeinschaftsdiagnose teilnehmenden Wirtschaftsforschungsinstitute einen Anstieg des Bruttoinlandsprodukts (BIP) um 2,1% im Jahr 2015 und um 1,8% im Jahr 2016. Die Institute korrigieren damit ihre Prognose vom Herbst 2014 erheblich nach oben; vor einem halben Jahr war für 2015 noch eine Veränderungsrate von 1,2% erwartet worden. Ein großer Teil der Revision geht auf eine seit dem Herbst unerwartet deutliche Verbesserung der Rahmenbedingungen für die deutsche Konjunktur zurück. Vor allem der massive Rückgang des Ölpreises stimuliert die deutsche Wirtschaft, aber auch die deutliche Abwertung des Euro, die mit der Ausweitung der Anleiheankaufprogramme der Europäischen Zentralbank einherging.

Zur Wirtschaftspolitik: Investitionen fördern – aber nicht allein mit mehr öffentlichen Mitteln!

Konjunktur aktuell,
No. 1,
2015
Abstract
Seit Ausbruch der europäischen Schulden- und Vertrauenskrise stellten sich der Wirtschaftspolitik in Deutschland vermeintlich ganz andere Aufgaben als auf europäischer Ebene. Es herrschte der Eindruck vor, dass Deutschland im Vergleich zu den Krisenländern strukturell gut aufgestellt sei. Der Rückgang der konjunkturellen Dynamik in Deutschland lenkt nunmehr die Aufmerksamkeit auch wieder verstärkt auf wirtschaftspolitische Herausforderungen im Inland.

Understanding the Great Recession
Mathias Trabandt, Lawrence J. Christiano, Martin S. Eichenbaum
American Economic Journal: Macroeconomics,
No. 1,
2015
Abstract
We argue that the vast bulk of movements in aggregate real economic activity during the Great Recession were due to financial frictions. We reach this conclusion by looking through the lens of an estimated New Keynesian model in which firms face moderate degrees of price rigidities, no nominal rigidities in wages, and a binding zero lower bound constraint on the nominal interest rate. Our model does a good job of accounting for the joint behavior of labor and goods markets, as well as inflation, during the Great Recession. According to the model the observed fall in total factor productivity and the rise in the cost of working capital played critical roles in accounting for the small drop in inflation that occurred during the Great Recession.

The Quantity Theory Revisited: A New Structural Approach
Makram El-Shagi, Sebastian Giesen
Macroeconomic Dynamics,
No. 1,
2015
Abstract
We propose a unified identification scheme to identify monetary shocks and track their propagation through the economy. We combine three approaches dealing with the consequences of monetary shocks. First, we adjust a state space version of the P-star type model employing money overhang as the driving force of inflation. Second, we identify the contemporaneous impact of monetary policy shocks by applying a sign restriction identification scheme to the reduced form given by the state space signal equations. Third, to ensure that our results are not distorted by the measurement error exhibited by the official monetary data, we employ the Divisia M4 monetary aggregate provided by the Center for Financial Stability. Our approach overcomes one of the major difficulties of previous models by using a data-driven identification of equilibrium velocity. Thus, we are able to show that a P-star model can fit U.S. data and money did indeed matter in the United States.
