This paper introduces a set of axioms that define convex risk measures. Duality theory provides the representation theorem for these measures and the link with pricing rules. 2002 Published by Elsevier Science B.V. JEL classification: G11; G12; G13

Abstract Many financial instruments are designed with embedded leverage, such as options and leveraged exchange-traded funds (ETFs). Embedded leverage alleviates investors’ constraints, and, therefore, we hypothesize that lowers required returns. Consistent this hypothesis, find empirically ETFs provide significant amounts of leverage; increases return volatility in proportion to the higher is ...

We provide a necessary and a sufficient condition on an individual’s expected utility function under which any zero-mean idiosyncratic risk increases cautiousness (the derivative of the reciprocal of the absolute risk aversion), which is the key determinant for this individual’s demand for options and portfolio insurance.

Approximate Incremental Value-at-Risk formulae provide an easy-to-use preliminary guideline for risk allocation. Both the cases of risk adding and risk pooling are examined and beta-based formulae achieved. Results highlight how much the conditions for adding new risky positions are stronger than those required for risk pooling. JEL classification: C13; D81; G11; G12.

Abstract We exploit detailed transaction and position data for a sample of long-short equity hedge funds to study the trading activity fundamental investors. find that exhibit skill in opening positions, but they close their positions too early, thereby forgoing about one-third trades’ potential profitability. explain this behavior with limits arbitrage: early order reallocate capital more prof...
