We numerically solve systems of Black–Scholes formulas for implied volatility and implied risk-free rate of return. After using a seemingly unrelated regressions (SUR) model to obtain point estimates for implied volatility and implied risk-free rate, the options are re-priced using these...

This paper implements an algorithm that can be used to solve systems of Black-Scholes equations for implied volatility and implied risk-free rate of return. After using a seemingly unrelated regressions (SUR) model to obtain point estimates for implied volatility and implied risk-free rate, the...

This is an expositional note on the transversality condition in continuous time dynamic economic models. We illustrate the basic issues, using the neoclassical one-sector optimal growth asset pricing model. In this class of models the transversality condition is the natural link trying the...

We provide an extensive set of alternative models for the estimation of the real cost of equity in a sample of utilities firms in Brazil with monthly data from March 2006 to June 2011. The traditional CAPM is rejected, together with the Fama-French factors, due to a poor fit. Additional factors...

We study the effects of two measures of information dissemination on the determination of systemic risk. One measure is print-media consumer sentiment based while the other is volatility based. We find evidence that while the volatility measure (VIX) of future expectations has a more significant...
