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...

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...

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...

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...

Model Misspecification and Under-Diversification

Uppal, Raman; Wang, Tan - C.E.P.R. Discussion Papers - 2002

In this Paper we develop a model of intertemporal portfolio choice where an investor accounts explicitly for the possibility of model misspecification. This work is motivated by the difficulty in estimating precisely the probability law for asset returns. Our contribution is to develop a...

Aspirations, Well-being, Risk-Aversion and Loss-Aversion

Koedijk, Kees; Pownall, Rachel A J; Statman, Meir - C.E.P.R. Discussion Papers - 2012

Financial well-being is distinct from income. Some people with high incomes suffer low financial well-being, as their incomes fall short of their aspirations. Such people feel propelled to reach their aspirations by taking risk and willing to bear losses. Conversely, some people with low incomes...

The Supermodular Stochastic Ordering

Meyer, Margaret A; Strulovici, Bruno - C.E.P.R. Discussion Papers - 2013

In many economic applications involving comparisons of multivariate distributions, supermodularity of an objective function is a natural property for capturing a preference for greater interdependence. One multivariate distribution dominates another according to the `supermodular stochastic...

Risk Aversion in a Dynamic Asset Allocation Experiment

We then fit the experimental choices to this model to assess the risk attitude of our subjects. Despite the … subjects is generally well accounted for by the HARA expected utility model.
