Neue Fragestellungen der monetäre Ökonomik betreffen seit der globalen Finanzmarktkrise sowohl die Erklärung der ungewöhnlichen Konsumentenpreisentwicklung als auch die Untersuchung der Interdependenzen zwischen den Finanzmärkten und der realen Wirtschaftstätigkeit sowie des geldpolitischen Transmissionsprozesses. In dieser Dissertation werden die Fragestellungen unter besonderer Berücksichtigung von Nichtlinearitäten analysiert. Die ersten beiden Beiträge untersuchen die Faktoren der Inflationsdynamik des Euroraums sowie der ASEAN-5-Länder anhand von nichtlinearen Phillips-Kurven und zeigen, dass die Veränderung der Inflationsprozesse bedeutend von den langfristigen Inflationserwartungen beeinflusst wird. Der dritte Beitrag untersucht die Entwicklung des Finanz-Akzelerator-Effektes (FAE) im Hinblick auf die Veränderung des Finanzsektors anhand eines zeitvarianten, strukturellen vektorautoregressiven Modells und zeigt, dass in den USA der FAE ab Anfang der 1990iger Jahre ansteigt.

Since the global financial crisis, economic literature has highlighted banks’ inclination to bolster up their liquid asset positions once the aggregate interbank funding market experiences a dry-up. To this regard, we show that liquidity hoarding and its detrimental effects on credit can also be triggered by idiosyncratic, i.e. bankspecific, interbank funding shocks with implications for monetary policy. Combining a unique data set of the Brazilian banking sector with a novel identification strategy enables us to overcome previous limitations for studying this phenomenon as a bankspecific event. This strategy further helps us to analyse how disruptions in the bank headquarters’ interbank market can lead to liquidity and lending adjustments at the regional bank branch level. From the perspective of the policy maker, understanding this market-to-market spillover effect is important as local bank branch markets are characterised by market concentration and relationship lending.

The adverse macroeconomic consequences of the Great Recession in 2009 spread well beyond the United States, highlighting the importance of financial stability and the housing market for real economic activity. Moreover, the vicious bank-sovereign cycle and the resulting sovereign-debt crisis of 2010-2012 posed a big threat to the survival of the Economic and Monetary Union (EMU) as a whole. While there is widespread consensus about the underlying causes of these crises, policy makers are still debating about what can be done to prevent future crises and, especially in the Euro area, deeply disagree on the direction of reforms. After all, most regulatory measures face not only the trade-off between financial resilience versus efficiency but also the fundamental choice between rule or discretion based interventions (Bénassy-Quéré et al., 2018).

We analyze the effect of monetary policy transparency on bilateral exchange rate volatility. We test the theoretical predictions of a stylized model using panel data for 62 currencies from 1998 to 2010. We find strong empirical evidence that an increase in the availability of information about monetary policy objectives decreases exchange rate volatility. Using interaction models, we find that this effect is more pronounced for countries with a lower flexibility of goods prices, a lower level of central bank conservatism, and a higher interest rate sensitivity of money demand.

Die Europäische Zentralbank (EZB) hat mit dem Securities Markets Programme (SMP) im Mai 2010 ein Instrument unkonventioneller Geldpolitik eingeführt. Im Rahmen des SMP erwarb sie im Wert von 218 Mrd. Euro Staatsanleihen ausgewählter Länder, welche erhöhten Risikoaufschlägen am Kapitalmarkt ausgesetzt waren. Eine mögliche Nebenwirkung solcher Ankaufprogramme ist es, auch jene Banken zu stützen, die nicht zum direkten Adressatenkreis gehören, aber Anleihen betroffener Länder in ihren Portfolios hielten. Möglicherweise resultierende Refinanzierungs-, Ertrags-, und Liquiditätsvorteile für bevorteilte Banken könnten zu Wettbewerbsverzerrungen führen. Dieser Beitrag betrachtet deshalb die Wertpapierportfolios regionaler deutscher Banken, um den kausalen Effekt des SMP auf das Wettbewerbsverhalten zu identifizieren. Die empirischen Befunde belegen in der Tat eine statistisch nachweisbare Zunahme der lokalen Marktanteile jener regionalen Banken, welche Anleihen in ihren Portfolios hielten, die Teil des SMP waren. Während dieses Ergebnis somit einen Beleg für die Existenz unbeabsichtigter Nebenwirkungen unkonventioneller Geldpolitik darstellt, so ist auch festzuhalten dass diese Wettbewerbseffekte ausgesprochen klein sind. Somit ist zumindest für den regionalen Bankenmarkt in Deutschland keine nennenswerte Verwerfung aufgrund dieses Ankaufprogramms festzustellen.

• Worldwide economic activity is vivid in summer 2017. Data on production for the first quarter of the year were only mixed: in the euro area quarterly growth was accelerating, but it went down in the US, Japan, and China. Other basic indicators, however, suggest that these economies continue expanding healthily. • Risks concerning the international economic policy framework remain, in particular since the economic agenda of the US government is still unclear, and no one knows whether the Brexit negotiations will lead the way to an orderly separation of Britain from the EU. • Production in the euro area has been expanding by more that 1 ½ % per year for almost three years now; since summer 2016, this expansion has even gained a bit of pace, mainly due to a expansion in France and, to a lesser extent, in Italy. • The ECB’s cautious hints at a coming normalization of monetary policy were enough to have a discernible effect on financial conditions at the end of June: yields for long term bonds rose, and the euro appreciated. That said, the common currency is still relatively cheap, and borrowing costs for non-financial firms and private households are still low. • Overall, we raise our GDP forecast for 2017 from 1.7% (spring report) to 2.1% and for 2018 to 1.8% (spring: 1.7%). We expect HICP inflation to remain well below the ECB target both in 2017 and 2018. • A major risk for the continuation of the current upswing in 2018 comes from the normalization of monetary policy: it is not clear by how much long term interests will rise and whether higher borrowing costs will jeopardize the confidence of financial markets in the solvency of some public debtors in the euro area.

Das Spring Meeting of Young Economists (SMYE) – eine große Konferenz von jungen Wirtschaftswissenschaftlern für junge Wirtschaftswissenschaftler – wird jedes Jahr im Auftrag der European Association of Young Economists (EAYE) in einer anderen europäischen Stadt durchgeführt. Vom 23. bis 25. März 2017 wurde das 22. SMYE vom Leibniz-Institut für Wirtschaftsforschung Halle (IWH) und der Martin-Luther-Universität Halle-Wittenberg (MLU) ausgerichtet und von sieben PostDocs und PhD-Studenten dieser Institutionen organisiert.

We find that career experience shapes the voting behavior of the Riksbank’s Monetary Policy Committee (MPC) members. Members with a career in the Riksbank and the government prefer higher rates. During a legislation with a center-right (center-left) party administration, MPC members with a career background in the government favor higher (lower) interest rates. Highlights: • The determinants of voting behavior in the Swedish Riksbank are considered. • Voting is analyzed with random effects ordered logit models for 1999–2013. • Interplay of career experience and political factors shapes voting behavior. • Government or Riksbank background leads to higher interest rate votes. • Partisan voting behavior is detected for members with government background.

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.

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.
