We consider an homogeneous class of assets, whose returns are driven by an unobservablefactor. We derive approximated prediction and pricing formulas for the future factorvalues and their proxies, when the size n of the class is large. Up to order 1=n, these approximationsinvolve solely...

The recursive prediction and filtering formulas of the Kalman filter are difficult to implementin nonlinear state space models. For Gaussian linear state space models, or for models with qualitativestate variables, the recursive formulas of the filter require the updating of a finite number...

We develop an econometric methodology to infer the path of risk premia from large unbalancedpanel of individual stock returns. We estimate the time-varying risk premia implied by conditional linearasset pricing models where the conditioning includes instruments common to all assets and asset...

The persistence of financial instability calls into question the adequacy of the current regulatory regime. Acritical review of the three pillars at the core of current financial regulation exposes some structural flaws.[...]

We want to assess the relationship between the equity and the debt cost of capital. Using a verysimple dividend discount model we compute the implied discount rate and we compare it with thecorresponding premium on the corporate credit default swap using a cointegration approach. Wedemonstrated...

We provide a new method to derive the state price density per unit probabilitybased on option prices and GARCH model. We derive the risk neutraldistribution using the result in Breeden and Litzenberger (1978) and thehistorical density adapting the GARCH model of Barone-Adesi, Engle, andMancini...

We study the influence of systematic probability misestimation on complexfinancial investment decisions on the context of structured financialproducts. Structured products have in recent years become more and morecomplex. We study the question whether this complexity might be a...

Evolutionary nance studies the dynamic interaction of investment strategies in nancialmarkets. This market interaction generates a stochastic wealth dynamics on aheterogenous population of traders through the uctuation of asset prices and theirrandom payos. Asset prices are endogenously...
