Demand-Based Option Pricing

Open access
Gârleanu, Nicolae, Pedersen, Lasse Heje, Poteshman, Allen M.·2009·Review of Financial Studies

Abstract

We model the demand-pressure effect on prices when options cannot be perfectly hedged.The model shows that demand pressure in one option contract increases its price by an amount proportional to the variance of the unhedgeable part of the option.Similarly, the demand pressure increases the price of any other option by an amount proportional to the covariance of their unhedgeable parts.Empirically, we identify aggregate positions of dealers and end users using a unique dataset, and show that demand-pressure effects help explain well-known option-pricing puzzles.First, end users are net long index options, especially out-of-money puts, which helps explain their apparent expensiveness and the smirk.Second, demand patterns help explain the prices of single-stock options.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
