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 paper presents empirical evidence on the effects of the Sarbanes-Oxley Act of 2002 on the value of firms and on the cross-listing choice of firms destined to three major markets in North America, Asia and Europe. We use dynamic panel data methods and treatment effects methods to find that...

This paper tests the main hypothesis that firms that cross-list have higher valuations, and provides evidence on the valuation effect of cross-listing on a major non-US market, the UK compared to the US market. We find evidence that there is a cross-listing premium in both markets. However, the...

We consider a dynamic allocation problem under alternative insurance and capital market regimes and proper risk aversion separate from intertemporal substitution. We apply the model to study the effect of one-size-fits-all transfers. We find that one-size-fits-all transfers can have different...
