Many institutional investors depend on the returns they generate to fund their operations and liabilities. How do these investors' financial conditions affect the management of their portfolios? We address this issue using the insurance industry because insurers are large investors for which...

We examine the impact of risk-based portfolio constraints on asset prices in an exchange economy. Constrained agents scale down their portfolio and behave locally like power utility investors with risk aversion that depends on current market conditions. The imposition of constraints dampens...

In this paper, we develop a new dynamic programming approach for solving an optimal retirement model in a two-dimensional incomplete market, which is induced by forced unemployment risk and borrowing constraints. We show that the two dimensions jointly affect an individual's optimal consumption,...

I study rollover risk in the wholesale funding market when intermediaries can hold liquidity ex-ante and are subject to fire sales ex-post. I demonstrate that precautionary liquidity restores multiple equilibria in a global rollover game. An intermediate liquidity level supports both the usual...

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....

We use cross-country microdata to analyse the risk taking of households in Europe and the US. Concerning the extensive as well as the intensive margin of risky assets, European households differ substantially from US households; but also inside Europe we document substantial differences....

The purpose of this paper is to study the compensation for in ation risks priced in sovereign bond yields. And we do so by modelling the time-varying dynamics of asset returns and inflation, and then estimating the cost of hedging in ation risks from the perspective of a well diversified...

We theoretically and empirically study large-scale portfolio allocation problems when transaction costs are taken into account in the optimization problem. We show that transaction costs act on the one hand as a turnover penalization and on the other hand as a regularization, which shrinks the...

This paper examines households' self-insurance in financial markets when a rare personal disaster, such as disability or long-term unemployment, may occur during working years. Personal disaster risk alters lifetime ex-ante investment choices, even if most workers will not experience a disaster....
