We analyze the impact of the French 2012 financial transaction tax (FTT) on trading volumes, stock prices, liquidity, and volatility. We extend the empirical research by identifying FTT announcement and short-run treatment effects, which can distort difference-in-differences estimates. In...

The Euro area faces zero inflation paired with low economic growth, at a time when the effective lower bound on nominal interest rates and large budget deficits are constraining conventional monetary and fiscal policy. In this article, we discuss the theoretical and empirical evidence on...

We analyze empirical links between the perceived tail-risk of inflation, the policy rate, longer-term interest rates, and equity prices in the U.S. Their simultaneous changes enable us to distinguish between a systematic and "exogenous" response to monetary-policy news. And, those tail...

The current macro-economic and financial conditions remain extremely challenging for the European insurance sector. Under the ongoing low yield environment insurers are changing their business models and looking for new investment and business opportunities to improve their profitability and the...

In this paper, we introduce a new Bayesian approach to explain some market anomalies during financial crises and subsequent recovery. We assume that the earnings shock of an asset follows a random walk model with and without drift to incorporate the impact of financial crises. We further assume...

In dieser Dissertation werden drei Corporate-Finance-Fragestellungen empirisch analysiert. Kapitel 1 untersucht, ob ein Zusammenhang besteht zwischen dem Ergebnis von Aktionärsabstimmungen zu Unternehmensübernahmen und kurzfristigen Kursreaktionen, sowie kurz- und langfristiger...

Unconventional fiscal policy uses announcements of future increases in consumption taxes to generate inflation expectations and accelerate consumption expenditure. It is budget neutral and time consistent. We exploit a unique natural experiment for an empirical test of the effectiveness of...

Unconventional monetary policies (UMPs) by the Federal Reserve, the European Central Bank, the Bank of England and the Bank of Japan exert important spillover effects on asset prices in Switzerland if market anticipation of UMP announcements is properly accounted for. Using a broad event set and...

We analyze the impact of Eurozone/Germany and U.S. macroeconomic news announcements and the communication of the monetary policy settings of the ECB and the Fed on the forex markets of new EU members. We employ an Event Study Methodology to analyze intra-day data from 2011-2015. Our...
