We generalize the classic Grossman and Laroque (1990) (GL) model of optimal portfolio choice with housing and transaction costs by introducing predictability in house prices. As in the GL model, agents only move to more expensive (cheaper) houses when their wealth-to-housing ratios reach an...

We consider the problem of portfolio selection within the classical Markowitz meanvariance optimizing framework, which has served as the basis for modern portfolio theory for more than 50 years. Efforts to translate this theoretical foundation into a viable portfolio construction algorithm have...

We measure the commonality in hedge fund returns, identify its main driving factor and analyse its implications for financial stability. We find that hedge funds’ commonality increased significantly from 2003 until 2006. We attribute this rise mainly to the increase in hedge funds’ exposure...

Using bilateral data on international equity and bond flows, we find that the prediction of the International Capital Asset Pricing Model is partially met and that global equity markets might be more integrated than global bond markets. Moreover, over the turbulent 1998-2001 period characterised...

We study whether a pre-existing link between bank and sovereign credit risk biased euro area banks' sovereign debt portfolio choices during 2011Q4 and 2012Q1 - a period of exceptional increases in their domestic sovereign bond holdings. We find that banks whose creditworthiness is linked to that...

This paper investigates whether global investors are over or under exposed towards the euro area and the role of home bias and institutions at home in shaping this exposure. According to a simple benchmark from standard portfolio theory, euro area investors - in particular those from euro area...

This paper uses a unique comprehensive database on French security assets and liabilities to study the dynamics of domestic and external sectoral portfolios, their network structure, and their role in the propagation of shocks. We first show how the sharp deterioration of the net external...
