When an underlying yields a stochastic dividend yield, derivatives with linear payoff at their maturities that are written on this underlying have the following properties: (i) they have a unique price only if markets are complete; (ii) the dynamic strategies that replicate these contingent...

This paper assesses the impact of environmental corporate social responsibility (ECSR) on Corporate Financial Performance (CFP) measured by ROA and Tobin's Q. We show that the relationship between firms' return on assets (ROA) and ECSR, strengths and concerns, is negative and statistically...
