We collect simple and pragmatic exact formulae for the convexity adjustment of irregular interest rate cash flows as … derive an additional new convexity adjustment for the volatility to be used in a standard Black & Scholes model. We study the …

-free communication structure, it is the solution proposed by Herings, van der Laan and Talman (2008). We introduce the notion of link-convexity …, under which the game is shown to have a non-empty core and the average tree solution lies in the core. In general, link-convexity … is weaker than convexity. For games with a cycle-free communication structure, link-convexity is even weaker than super-additivity. …

Leading by these considerations, in this paper we propose a … measures of efficiency provide also indicators of convexity. Illustrations through simulated and real data (mutual funds …
