Abstracts
Is Idiosyncratic Volatility Risk Priced? Evidence from the Physical and RiskNeutral Distributions (Job Market Paper )
We use simultaneous data from equity, index and option markets in order to estimate a
single factor market model in which idiosyncratic volatility is allowed to be priced. We
model the index dynamics’ P-distribution as a mean-reverting stochastic volatility model as
in Heston (1993), and the equity returns as single factor models with stochastic idiosyncratic
volatility terms. We derive theoretically the underlying assets’ Q-distributions and estimate
the parameters of both P- and Q-distributions using a joint likelihood function. We document
the existence of a common factor structure in option implied idiosyncratic variances. We
show that the average idiosyncratic variance, which proxies for the common factor, is priced
in the cross section of equity returns, and that it reduces the pricing error when added to
the Fama-French model. We find that the idiosyncratic volatilities differ under P- and Qmeasures, and we estimate the price of this idiosyncratic volatility risk, which turns out to
be always significantly different from zero for all the stocks in our sample. Further, we show
that the idiosyncratic volatility risk premiums are not explained by the usually equity risk
factors. Finally, we explore the implications of our results for the estimates of the conditional
equity betas.
Valuing Catastrophe Derivatives under Limited Diversification: a Stochastic
Dominance Approach
We present a new approach to the pricing of catastrophe event derivatives that does not
assume a fully diversifiable event risk. Instead, we assume that the event occurrence and
intensity affect the return of the market portfolio of an agent that trades in the event derivatives. Based on this approach, we derive values for a CAT option and a reinsurance contract
on an insurers assets using recent results from the option pricing literature. We show that
the assumption of unsystematic event risk seriously underprices the CAT option. Last,
we present numerical results for our derivatives using real data from hurricane landings in
Florida.
Catastrophe Derivatives and Reinsurance Contracts: An Incomplete Markets
Approach
We apply a recently developed new approach to the pricing of catastrophe derivatives to
the valuation of a reinsurance contract. Since the payoff of that contract has the form of
a vertical spread, our methodology is also applicable to the valuation of such spreads in
other markets. We do not assume a fully diversifiable CAT event risk. Instead, we assume
that there exists a class of investors whose diversified portfolios return is negatively affected
by the occurrence of the CAT event. We derive bounds for a reinsurance contract with
a non-convex payoff using recent results from the option pricing literature; we also show
that these bounds are tighter than the ones arising from a combination of the bounds of
the options forming the spread. We also present the derivation of the same bounds based
on stochastic dominance criteria, and the trading strategies exploiting the mispricings. We
adopt a recursive discrete time approach as more realistic for the class of problems that we
examine, and we value numerically the reinsurance contract with real data from hurricane
landings in Florida. Last, we show that the limiting pricing kernels defining the bounds for
derivative assets of this type are crucially dependent on the shape of the derivatives payoff
function and do not have a closed form expression.
