We propose and implement a procedure to optimally hedge climate change risk. First, we construct climate risk indices through textual analysis of newspapers. Second, we present a new approach to compute factor mimicking portfolios to build climate risk hedge portfolios. The new mimicking...

The paper proposes a framework for large-scale portfolio optimization which accounts for all the major stylized facts of multivariate financial returns, including volatility clustering, dynamics in the dependency structure, asymmetry, heavy tails, and nonellipticity. It introduces a so-called...

Multivariate GARCH models do not perform well in large dimensions due to the so-called curse of dimensionality. The recent DCC-NL model of Engle et al. (2019) is able to overcome this curse via nonlinear shrinkage estimation of the unconditional correlation matrix. In this paper, we show how...

Modeling and forecasting dynamic (or time-varying) covariance matrices has many important applications in finance, such as Markowitz portfolio selection. A popular tool to this end are multivariate GARCH models. Historically, such models did not perform well in large dimensions due to the...

This report reviews recent as well as planned changes to accounting and solvency regulations affecting insurers and pension funds and how they may impact long-term investing by these institutions. The review of existing evidence focuses mainly on the impact of risk-based solvency requirements,...

We review the international finance literature to assess the extent to which international factors affect financial asset demands and prices. International asset-pricing models with mean-variance investors predict that an asset's risk premium depends on its covariance with the world market...

Motivated from investment-based asset pricing, we propose a new factor model that consists of the market factor, a size factor, an investment factor, and a return-on-equity factor. The new model [i] outperforms the Carhart (1997) four-factor model in pricing portfolios formed on earnings...

We develop a two-period general equilibrium model of portfolio delegation with competitive, differentially skilled managers and convex compensation contracts. We show that convex incentives lead to significant equilibrium mispricing, but reduce price volatility. In particular, price...
