Deriving an optimal asset allocation for institutional investors hinges crucially on the quality of inputs used in the optimization. If the mean vector and the covariance matrix are known with certainty, the classical mean-variance optimization of Markowitz (1952) produces optimal portfolios....

Does extreme downside risk require a risk premium in the pricing of individual assets? Extreme downside risk is a conditional measure for the co-movement of individual stocks with the market, given that the state of the world is extremely bad. This measure, derived from statistical extreme value...

There are concerns that climate-related physical and political risks are not yet properly reflected in asset prices. To address these concerns, we develop a dynamic asset pricing framework with two sources of rare disasters: macroeconomic events and climate change. We link carbon emissions and...

This paper examines the investment behavior of different financial institutions in debt securities with a particular focus on their response to price changes. For identification, we use security-level data from the German Microdatabase Securities Holdings Statistics. Our results suggest that...

Delegation bears an intrinsic form of uncertainty. Investors hire managers for their superior models of asset markets, but delegation outcome is uncertain precisely because managers' model is unknown to investors. We model investors' delegation decision as a trade-off between asset return...

We show that there exists significant heterogeneity across U.S. households in how uncertain they are in their expectations regarding personal and macroeconomic outcomes, and that uncertainty in expectations predicts households' choices. Individuals with lower income or education, more precarious...

This paper contrasts the investment behavior of different financial institutions in debt securities as a response to past returns. For identification, I use unique security-level data from the German Micro-database Securities Holdings Statistics. Banks and investment funds respond in a...

We examine the relationship between private bank deposits and macro/fiscal risk in the euro area. We test three hypotheses: First, private bank deposits relative to Germany are determined by macro/fiscal risk factors. Second, this relationship is time-varying. Third, time-variation is driven by...

We investigate the effect of introducing information about peer portfolios in an experimental Arrow-Debreu economy. Confirming the prediction of a general equilibrium model with inequality averse preferences, we find that peer information leads to reduced variation in payoffs within peer groups....

We propose and implement a procedure to dynamically hedge climate change risk. We extract innovations from climate news series that we construct through textual analysis of newspapers. We then use a mimicking portfolio approach to build climate change hedge portfolios. We discipline the exercise...
