This paper studies the impact of major ECB monetary policy announcements on the portfolio allocation of euro area fund investors, using daily data between 2012 and mid-2016, a period that includes a variety of unconventional measures. We distinguish between active portfolio reallocation, driven...

Reserve portfolios prior to the Global Financial Crisis provided positive (low) returns for central banks or had extremely low probabilities of earning negative returns.

Using data on sector-level value added for a wide cross section of countries and for various levels of disaggregation, we construct...

We study the effect of financial markets on "optimal" diversification defined in the spirit of mean-variance efficiency as a pattern of output reallocation across industrial sectors which simultaneously accounts for the sectors' growth, volatility, and correlations. Our findings imply that...

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...
