Mean-variance criteria remain prevalent in multi-period problems, and yet not much is known about their dynamically optimal policies. We provide a fully analytical characterization of the optimal dynamic mean-variance portfolios within a general incomplete-market economy, and recover a simple...

Using a calibrated OLG model with several sources of uncertainty we find that the impact of ageing and of reform of social security upon the demand for housing and the level of owner occupation is substantial. The overall structure of household asset holdings – in particular the split between...

Despite much work on hedging in incomplete markets, the literature still lacks tractable dynamic hedges in plausible environments. In this article, we provide a simple solution to this problem in a general incomplete-market economy in which a hedger, guided by the traditional minimum-variance...

Money managers behave strategically when competing for fund flows within relatively small groups. We study strategic interaction between two risk-averse managers in continuous time, characterizing analytically their unique equilibrium dynamic investments. Driven by chasing and contrarian...

We examine the activity and performance of a large panel of individual investors (approximately 70,000 investors and their daily returns over the 2000 to 2010 period) in Sweden's Premium Pension System. We document strong inertia in individuals' choices and changes of mutual funds. We find that...

The eurozone has a single short-term nominal interest rate, but monetary policy conditions measured by either real short-term interest rates or Taylor rule residuals varied substantially across countries in the period from 2003-2010. We use this cross-country variation in the (local) tightness...
