Monetäre Aggregate, Vermögenspreise und realwirtschaftliche Effekte

Diese Forschungsgruppe erforscht – auch vor dem Hintergrund der jüngsten Krisen – den Zusammenhang zwischen monetären Aggregaten, Vermögenspreisen und realwirtschaftlichen Schwankungen. Ein besonderer Schwerpunkt liegt auf der Entwicklung allgemeiner Gleichgewichtsmodelle, die diese Zusammenhänge explizit abbilden.

Evidence on the Effects of Inflation on Price Dispersion under Indexation

Juliane Scharff S. Schreiber

in: Empirical Economics, Nr. 1, 2012

Abstract

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

Herbert S. Buscher Hubert Gabrisch

in: Empirica, Nr. 3, 2012

Abstract

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

Alexander Kriwoluzky

in: European Economic Review, Nr. 3, 2012

Abstract

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

A. Heise Toralf Pusch

in: International Journal of Public Policy, Nr. 1, 2011

Abstract

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

Dieter Nautz Juliane Scharff

in: Applied Economics, Nr. 4, 2012

Abstract

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.).

Why is Unemployment so Countercyclical?

Lawrence J. Christiano Martin S. Eichenbaum Mathias Trabandt

in: NBER Working Paper No. 26723, 2020

Abstract

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

Abstract

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.

The Appropriateness of the Macroeconomic Imbalance Procedure for Central and Eastern European Countries

Martina Kämpfe Tobias Knedlik

in: IWH-Diskussionspapiere, Nr. 16, 2017

Abstract

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

Yoosoon Chang Boreum Kwak

in: IWH-Diskussionspapiere, Nr. 15, 2017

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.

Monetary Policy in an Oil-dependent Economy in the Presence of Multiple Shocks

Andrej Drygalla

in: IWH-Diskussionspapiere, Nr. 14, 2017

Abstract

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.
