Asset Pricing under Rational Learning about Rare Disasters
Koulovatianos, Christos; Wieland, Volker - C.E.P.R. Discussion Papers - 2011
This paper proposes a new approach for modeling investor fear after rare disasters. The key element is to take into account that investors' information about fundamentals driving rare downward jumps in the dividend process is not perfect. Bayesian learning implies that beliefs about the...

Dynamic Hedging in Incomplete Markets: A Simple Solution
Basak, Suleyman; Chabakauri, Georgy - C.E.P.R. Discussion Papers - 2011
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...

Strategic Asset Allocation in Money Management
Basak, Suleyman; Makarov, Dmitry - C.E.P.R. Discussion Papers - 2011
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...

Dynamic Mean-Variance Asset Allocation
Basak, Suleyman; Chabakauri, Georgy - C.E.P.R. Discussion Papers - 2009
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...

Portfolio Selection with Parameter and Model Uncertainty: A Multi-Prior Approach
Garlappi, Lorenzo; Uppal, Raman; Wang, Tan - C.E.P.R. Discussion Papers - 2005
In this paper, we show how an investor can incorporate uncertainty about expected returns when choosing a mean-variance optimal portfolio. In contrast to the Bayesian approach to estimation error, where there is only a single prior and the investor is neutral to uncertainty, we consider the case...

Keynes Meets Markowitz: The Trade-off Between Familiarity and Diversification

The calibration shows that when the overall ambiguity about the joint distribution of returns is high …

A Model of Credit Risk, Optimal Policies and Asset Prices
Basak, Suleyman; Shapiro, Alex - C.E.P.R. Discussion Papers - 2002
This Paper studies the optimal policies of borrowers (firms or individuals) who may default subject to default costs, and analyses the asset pricing implications. Borrowers defaulting under adverse economic conditions may, despite incurring default costs, emerge as wealthier than non-borrowers...

The Impact of Changing Demographics and Pensions on The Demand for Housing and Financial Assets
Cerny, Ales; Miles, David K; Schmidt, Lubomir - C.E.P.R. Discussion Papers - 2005
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...
