Published / Preprint: Collective Philanthropy: Describing and Modeling the Ecology of Giving. (arXiv:1307.2278v1 [physics.soc-ph])

Posted: 09 Jul 2013 05:38 PM PDT

Reflective of income and wealth distributions, philanthropic gifting appears to follow an approximate power-law size distribution as measured by the size of gifts received by individual institutions. We explore the ecology of gifting by analysing data sets of individual gifts for a diverse group of institutions dedicated to education, medicine, art, public support, and religion. We find that the...

Published / Preprint: Strict Local Martingales with Jumps. (arXiv:1307.2436v1 [math.PR])

A strict local martingale is a local martingale which is not a martingale. There are few explicit examples of "naturally occurring" strict local martingales with jumps available in the literature.

Published / Preprint: On model-independent pricing/hedging using shortfall risk and quantiles. (arXiv:1307.2493v1 [q-fin.PR])

Posted: 09 Jul 2013 05:38 PM PDT

We consider the pricing and hedging of exotic options in a model-independent set-up using \emph{shortfall risk and quantiles}. We assume that the marginal distributions at certain times are given. This is tantamount to calibrating the model to call options with discrete set of maturities but a continuum of strikes. In the case of pricing with shortfall risk, we prove that the minimum initial...
