Downside risk and asset pricing

Dynamic Asset Allocation and Downside-Risk Aversion

This paper considers dynamic asset allocation in a mean versus downside-risk framework. We derive closed-form solutions for the optimal portfolio weights when returns are lognormally distributed. Moreover, we study the impact of skewed and fat-tailed return distributions. We nd that the optimal fraction invested in stocks is V-shaped: at low and high levels of wealth the investor increases the ...

Technological Growth, Asset Pricing, and Consumption Risk

In this paper we develop a theoretical model in order to understand co-movements between asset returns and consumption over short and long horizons. We present an intertemporal general equilibrium model featuring two types of shocks: "small", frequent and disembodied shocks to productivity and "large" technological innovations, which are embodied into new vintages of the capital stock. The latt...

Default Risk, Asset Pricing and Equity Premium∗

In order to exp...
