Monetary Aggregates, Asset Prices and Real Outcomes

Paying close attention to money, credit, and asset prices shall improve the IWH's macroeconomic policy work, especially in terms of forecasting macroeconomic developments and risks, but also in terms of assessing the stance of monetary policy. To this end, it is necessary to understand the relationship between monetary and financial developments, on the one hand, and macroeconomic dynamics and stability, on the other hand. Money and credit are important determinants of the macroeconomic performance of a market economy. Research in this group contributes to the literature on quantitative macroeconomic models to be applied for forecasting and policy analysis that incorporate monetary and financial aspects.

Reconciling Narrative Monetary Policy Disturbances with Structural VAR Model Shocks?

Martin Kliem Alexander Kriwoluzky

in: Economics Letters, No. 2, 2013


Structural VAR studies disagree with narrative accounts about the history of monetary policy disturbances. We investigate whether employing the narrative monetary shocks as a proxy variable in a VAR model aligns both shock series. We find that it does not.

Explosive Preisentwicklung und spekulative Blasen auf Rohstoffmärkten

Oliver Holtemöller

in: ORDO, No. 64, 2013


This paper analyzes whether price developments on commodity markets support the hypothesis that commodity prices are subject to speculative behavior in certain time periods. This is an important research question within the ongoing debate on the regulation of commodity trading. It can be shown that commodity prices occasionally exhibit explosive behavior. In particular, this is found for raw industrials, but also for foodstuff. An important implication is that the reasons and the effects on consumers and investors of bubbles on commodity markets have to be investigated in greater detail. Additionally, the distributional effects of these findings should be analyzed in future research.

The New EU Countries and Euro Adoption

Hubert Gabrisch Martina Kämpfe

in: Intereconomics, No. 3, 2013


In the new member states of the EU which have not yet adopted the euro, previous adoption strategies have come under scrutiny. The spillovers and contagion from the global financial crisis revealed a new threat to the countries’ real convergence goal, namely considerable vulnerability to the transmission of financial instability to the real economy. This paper demonstrates the existence of extreme risks for real convergence and argues in favour of a new adoption strategy which does not announce a target date for the currency changeover and which allows for more flexible and countercyclical monetary, fiscal and wage policies.

Money and Inflation: Consequences of the Recent Monetary Policy

Makram El-Shagi Sebastian Giesen

in: Journal of Policy Modeling, No. 4, 2013


We use a multivariate state space framework to analyze the short run impact of money on prices in the United States. The key contribution of this approach is that it allows to identify the impact of money growth on inflation without having to model money demand explicitly. Using our results, that provide evidence for a substantial impact of money on prices in the US, we analyze the consequences of the Fed's response to the financial crisis. Our results indicate a raise of US inflation above 5% for more than a decade. Alternative exit strategies that we simulate cannot fully compensate for the monetary pressure without risking serious repercussions on the real economy. Further simulations of a double dip in the United States indicate that a repetition of the unusually expansive monetary policy – in addition to increased inflation – might cause growth losses exceeding the contemporary easing of the crisis.

Has the Euro Increased International Price Elasticities?

Oliver Holtemöller Götz Zeddies

in: Empirica, No. 1, 2013


The introduction of the Euro has been accompanied by the hope that international competition between EMU member states would increase due to higher price transparency. This paper contributes to the literature by analyzing price elasticities in international trade flows between Germany and France and between Germany and the United Kingdom before and after the introduction of the Euro. Using disaggregated Eurostat trade statistics, we adopt a heterogeneous dynamic panel framework for the estimation of price elasticities. We suggest a Kalman-filter approach to control for unobservable quality changes which otherwise would bias estimates of price elasticities. We divide the complete sample, which ranges from 1995 to 2008, into two sub-samples and show that price elasticities in trade between EMU members did not change substantially after the introduction of the Euro. Hence, we do not find evidence for an increase in international price competition resulting from EMU.

Sovereign Default Risk, Macroeconomic Fluctuations and Monetary-Fiscal Stabilisation

Markus Kirchner Malte Rieth

in: IWH Discussion Papers, No. 22, 2020


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.

Exchange Rates and the Information Channel of Monetary Policy

Oliver Holtemöller Alexander Kriwoluzky Boreum Kwak

in: IWH Discussion Papers, No. 17, 2020


We disentangle the effects of monetary policy announcements on real economic variables into an interest rate shock component and a central bank information shock component. We identify both components using changes in interest rate futures and in exchange rates around monetary policy announcements. While the volatility of interest rate surprises declines around the Great Recession, the volatility of exchange rate changes increases. Making use of this heteroskedasticity, we estimate that a contractionary interest rate shock appreciates the dollar, increases the excess bond premium, and leads to a decline in prices and output, while a positive information shock appreciates the dollar, decreases prices and the excess bond premium, and increases output.

The Evolution of Monetary Policy in Latin American Economies: Responsiveness to Inflation under Different Degrees of Credibility

Stefan Gießler

in: IWH Discussion Papers, No. 9, 2020


This paper investigates the forward-lookingness of monetary policy related to stabilising inflation over time under different degrees of central bank credibility in the four largest Latin American economies, which experienced a different transition path to the full-fledged inflation targeting regime. The analysis is based on an interest rate-based hybrid monetary policy rule with time-varying coefficients, which captures possible shifts from a backward-looking to a forward-looking monetary policy rule related to inflation stabilisation. The main results show that monetary policy is fully forward-looking and exclusively reacts to expected inflation under nearly perfect central bank credibility. Under a partially credible central bank, monetary policy is both backward-looking and forward-looking in terms of stabilising inflation. Moreover, monetary authorities put increasingly more priority on stabilising expected inflation relative to actual inflation if central bank credibility tends to improve over time.

Why is Unemployment so Countercyclical?

Lawrence J. Christiano Martin S. Eichenbaum Mathias Trabandt

in: NBER Working Paper No. 26723, 2020


We argue that wage inertia plays a pivotal role in allowing empirically plausible variants of the standard search and matching model to account for the large countercyclical response of unemployment to shocks.

Resolving the Missing Deflation Puzzle

Jesper Lindé Mathias Trabandt

in: CEPR Discussion Papers 13690, 2019


We propose a resolution of the missing deflation puzzle. Our resolution stresses the importance of nonlinearities in price- and wage-setting when the economy is exposed to large shocks. We show that a nonlinear macroeconomic model with real rigidities resolves the missing deflation puzzle, while a linearized version of the same underlying nonlinear model fails to do so. In addition, our nonlinear model reproduces the skewness of inflation and other macroeconomic variables observed in post-war U.S. data. All told, our results caution against the common practice of using linearized models to study inflation and output dynamics.
