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.

Effects of exchange rate changes on production and inflation
Evidence on the Effects of Inflation on Price Dispersion under Indexation
in: Empirical Economics, No. 1, 2012
Distortionary effects of inflation on relative prices are the main argument for inflation stabilization in macro models with sticky prices. Under indexation of non-optimized prices, those models imply a nonlinear and dynamic impact of inflation on the cross-sectional price dispersion (relative price or inflation variability, RPV). Using US sectoral price data, we estimate such a relationship between inflation and RPV, also taking into account the endogeneity of inflation by using two- and three-stage least-squares and GMM techniques, which turns out to be relevant. We find an effect of (expected) inflation on RPV, and our results indicate that average (“trend”) inflation is important for the RPV-inflation relationship. Lagged inflation matters for indexation in the CPI data, but is not important empirically in the PPI data.
The Synchronization of Wage Dynamics across EMU Members: A Test of the Endogeneity Hypothesis
in: Empirica, No. 3, 2012
We test the hypothesis of an endogenous currency area for the labor market of the Euro area: has the introduction of a common currency caused wage dynamics to become more synchronized and to be able to cushion for asymmetric shocks? Trade intensity, sector specialization and financial integration are tested for being the driving forces for the endogenous synchronization of wage dynamics. We use regression techniques with instrument variables, and find evidence of persistent asymmetries in nominal wage formation, despite a single currency and monetary policy. We explain the result with more specialization following financial integration, and with still existing differences in wage formation and labor market institutions. We conclude that the euro zone is not endogenous with respect to wage formation. Rather, there are incentives for beggar-thy-neighbor policies in the Euro area.
Pre-announcement and Timing: The Effects of a Government Expenditure Shock
in: European Economic Review, No. 3, 2012
An econometric strategy to identify a pre-announced fiscal policy shock is proposed. I show that the reduced form innovations can be recovered by estimating a Vector-moving-average model using the Kalman filter. The structural effects are identified exploiting the shock's pre-announced nature, which leads to potentially different signs of the responses of some endogenous variables during the announcement and after the realization of the shock. I illustrate my strategy by identifying a pre-announced shock to government consumption expenditures. I find that the response of private consumption is significantly negative on impact, rises and becomes significantly positive two quarters after the realization of the policy shock.
On the Institutional Safeguarding of Monetary Policy – a Post-Keynesian Perspective
in: International Journal of Public Policy, No. 1, 2011
The paper takes a fresh look at the governance of the most important macroeconomic objectives: price stability and full employment. On the basis of a post-Keynesian market constellations approach, the necessity and institutional requirements of the coordination of macroeconomic policy areas in general and an optimal central bank setting in particular are analysed, and an amelioration of monetary policy of the neo-Keynesian ‘new macroeconomic consensus’ is provided.
Inflation and Relative Price Variability in the Euro Area: Evidence from a Panel Threshold Model
in: Applied Economics, No. 4, 2012
The impact of inflation on Relative Price Variability (RPV) generates an important channel for real effects of inflation. This article provides first evidence on the empirical relation between inflation and RPV in the euro area. Stirred by the widespread use of inflation caps or target bands in monetary policy practice, we are particularly interested in threshold effects of inflation. In line with the predictions of monetary search models, our results indicate that expected inflation significantly increases RPV only if inflation is either very low (below 0.95% per annum (p.a.)) or very high (above 4.96% p.a.).
The Appropriateness of the Macroeconomic Imbalance Procedure for Central and Eastern European Countries
in: IWH Discussion Papers, No. 16, 2017
The experience of Central and Eastern European countries (CEEC) during the global financial crisis and in the resulting European debt crises has been largely different from that of other European countries. This paper looks at the specifics of the CEEC in recent history and focuses in particular on the appropriateness of the Macroeconomic Imbalances Procedure for this group of countries. In doing so, the macroeconomic situation in the CEEC is highlighted and macroeconomic problems faced by these countries are extracted. The findings are compared to the results of the Macroeconomic Imbalances Procedure of the European Commission. It is shown that while the Macroeconomic Imbalances Procedure correctly identifies some of the problems, it understates or overstates other problems. This is due to the specific construction of the broadened surveillance procedure, which largely disregarded the specifics of catching-up economies.
U.S. Monetary-Fiscal Regime Changes in the Presence of Endogenous Feedback in Policy Rules
in: IWH Discussion Papers, No. 15, 2017
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.
Monetary Policy in an Oil-dependent Economy in the Presence of Multiple Shocks
in: IWH Discussion Papers, No. 14, 2017
Russian monetary policy has been challenged by large and continuous private capital outflows and a sharp drop in oil prices during 2014, with both ongoings having put a significant depreciation pressure on the ruble and having led the central bank to eventually give up its exchange rate management strategy. Against this background, this paper estimates a small open economy model for Russia, featuring an oil price sector and extended by a specification of the foreign exchange market to correctly account for systematic central bank interventions. We find that shocks to the oil price and private capital flows substantially affect domestic variables such as inflation, output and the exchange rate. Simulations of the model for the estimated actual strategy and five alternative regimes suggest that the vulnerability of the Russian economy to external shocks can substantially be lowered by adopting some form of an inflation targeting strategy. Foreign exchange intervention-based policy strategies to target the nominal exchange rate or the ruble price of oil, on the other hand, prove inferior to the policy in place.
Same, but Different: Testing Monetary Policy Shock Measures
in: IWH Discussion Papers, No. 9, 2017
In this study, we test whether three popular measures for monetary policy, that is, Romer and Romer (2004), Barakchian and Crowe (2013), and Gertler and Karadi (2015), constitute suitable proxy variables for monetary policy shocks. To this end, we employ different test statistics used in the literature to detect weak proxy variables. We find that the measure derived by Gertler and Karadi (2015) is the most suitable in this regard.
Do We Need New Modelling Approaches in Macroeconomics?
in: IWH Discussion Papers, No. 8, 2014
The economic and financial crisis that emerged in 2008 also initiated an intense discussion on macroeconomic research and the role of economists in society. The debate focuses on three main issues. Firstly, it is argued that economists failed to predict the crisis and to design early warning systems. Secondly, it is claimed that economists use models of the macroeconomy which fail to integrate financial markets and which are inadequate to model large economic crises. Thirdly, the issue has been raised that economists invoke unrealistic assumptions concerning human behaviour by assuming that all agents are self-centred, rationally optimizing individuals. In this paper, we focus on the first two issues. Overall, our thrust is that the above statements are a caricature of modern economic theory and empirics. A rich field of research developed already before the crisis and picked up shortcomings of previous models.
