abstract = "An empirical study of the Brazilian option market is presented in
light of three option pricing models, namely the BlackScholes
model, the exponential model, and a model based on a power law
distribution, the so-called q-Gaussian distribution or Tsallis
distribution. It is found that the q-Gaussian model performs
better than the BlackScholes model in about one third of the
option chains analyzed. But among these cases, the exponential
model performs better than the q-Gaussian model in 75% of the
time. The superiority of the exponential model over the q-Gaussian
model is particularly impressive for options close to the
expiration date, where its success rate rises above ninety
percent.",
