We examine how monetary policy of the Federal Reserve System, COVID-19 mortality cases, and vaccinations are associated with the US stock market volatility during the pandemic period. Using the wavelet coherence analysis, we first find that there is a positive relationship between the volatility...

This study empirically examines the spillover effect from US monetary policy to nineteen European economies using Markov-switching models. The results of the univariate Markov-switching models validate the presence of two distinct regimes for both US monetary policy and the stock markets. We...

Although the effects of economic news announcements on asset prices are well established, theserelationships are unlikely to be stable. This paper documents the time variation in the responses of yield curves and exchange rates using high-frequency data from January 2000 through August 2011....

This paper reveals and tests a new theoretical implication of the credit channel of monetary policy: as financial frictions (monitoring or auditing costs) increase, the reaction of stock prices to monetary policy shocks decreases. Correspondingly, towards the end of the Enron accounting scandal,...

In this paper, we investigate the dynamic response of stock market volatility to changes in monetary policy. Using a vector autoregressive model, our findings reveal a significant and asymmetric response of stock returns and volatility to monetary policy shocks. Although the increase in the...

This paper investigates whether central banks can attenuate excessive mispricing in stocks as suggested by the proponents of a \leaning against the wind" (LATW) monetary policy. For this, we decompose stock prices into a fundamental component, a risk premium, and a mispricing component. We argue...

This paper examines whether the ECB's Quantitative Easing (QE) policy is causing government bond prices to deviate from their fundamental value. We use a recent advance in the methodology to measure exuberant price behavior in financial time series introduced by Phillips et al. (2015). We extend...

We study the role of asset revaluation in the monetary transmission mechanism. We build an analytical heterogeneous-agents model with two main ingredients: i) rare disasters; ii) heterogeneous beliefs. The model captures time-varying risk premia and precautionary savings in a setting that nests...

This doctoral dissertation analyses the transmission of monetary policy. It applies a variety of empirical methods to study how conventional and unconventional monetary policy measures transmit to different macroeconomic and financial variables. The first article analyses the effect of monetary...

We analyze optimal monetary policy and its implications for asset prices, when aggregate demand has inertia and responds to asset prices with a lag. If there is a negative output gap, the central bank optimally overshoots aggregate asset prices (asset prices are initially pushed above their...
