abstract = {We provide analytic pricing formulas for Fixed and Floating Range Accrual Notes within the multifactor Wishart affine framework which extends significantly the standard affine model. Using estimates for three short rate models, two of which are based on the Wishart process whilst the third one belongs to the standard affine framework, we price these structured products using the FFT methodology. Thanks to the Wishart tractability the hedge ratios are also easily computed. As the models are estimated on the same dataset, our results illustrate how the fit discrepancies (meaning differences in the likelihood functions) between models translate in terms of derivatives pricing errors, and we show that the models can produce different price evolutions for the Range Accrual Notes. The differences can be substantial and underline the importance of model risk both from a static and dynamic perspective. These results are confirmed by an analysis performed at the hedge ratios level.},

The working hypothesis is that market crashes are preceded by a bubble. The authors define a bubble as an anomalous increase in asset prices with respect to the economy. An exponentially growing spread between asset prices and the economy is therefore an indicator of the probability that a bubble is in the making. However, as the authors point out, this indicator alone is not sufficient as anomalous price growth can be generated by different macroeconomic scenarios. The authors discuss different macroscenarios that can lead to bubbles and the related indicators.},

We provide elements showing that the use of empirical characteristic function-based estimates is advisable as this function is exponential affine in the WASC case. We use a GMM estimation strategy with a continuum of moment conditions based on the characteristic function. We present the estimation results obtained using a dataset of equity indexes. The WASC model captures most of the known stylized facts associated with financial markets, including leverage and asymmetric correlation effects.},

More precisely we provide an expression of the conditional probability density of such coefficients, given a discrete observation grid. The noise is assumed to be described by a symmetric alpha-stable random variable. If the noise is a dynamic noise, then we present the exact expression of the probability density of each wavelet coefficient of the noisy signal. If we face a measurement noise, then the noise has a non-linear influence and we propose two approximations. The first one relies on a Taylor expansion whereas the second one, relying on an Edgeworth expansion, improves the first general Taylor approximation if the cumulants of the noise are defined. We give some illustrations of these theoretical results for the logistic map, the tent map and a multidimensional chaos, the Hénon map, disrupted by a Gaussian or a Cauchy noise.},

We show numerically that the global no-good-deal price can be significantly higher that the instantaneous one.

The findings also show that the proportion of institutional investors has a positive effect on market liquidity. These investors are inclined to trade more frequently on their stocks and to shrink bid-ask spreads. These findings are in line with adverse selection and trading hypotheses and shed the light on the role of corporate governance devices to consider shareholder minority interest's protection, which leads to improved stock market liquidity levels.},

abstract = {The Black-Scholes model has gained wide recognition on financial markets. One of its shortcomings, however, is that it is inconsistent with most observed
option prices. Although the model can still be used very efficiently, it has been proposed to relax its assumptions, and, for instance, to consider that the volatility of
the underlying asset S is no longer a constant but rather a stochastic process. There
are two well-known approaches to achieve this goal. In the first class of models, the
volatility is assumed to depend on the variables t (time) and S, giving rise to the
so-called local volatility models. The second one, conceptually more ambitious,
considers that the volatility has a stochastic component of its own. In the latter,
the number of factors is increased by the amount of stochastic factors entering the
volatility modeling. Both models are of practical interest.},
