Aid, Volatility, and Growth Again: When Aid Volatility Matters and When it Does Not [PDF]

open access: yesReview of Development Economics, 2009
AbstractIn previous papers the authors have argued that aid is likely to mitigate the negative effects of external shocks on economic growth (i.e. that aid is more effective in countries which are more vulnerable to external shocks). Recently an important debate has emerged about the possible negative effects of aid volatility itself.

Dark Matter in (Volatility and) Equity Option Risk Premiums

open access: yesOperations Research, 2022
In their paper, “Dark Matter in (Volatility and) Equity Option Risk Premiums,” Bakshi, Crosby, and Gao ask a provocative question: is there dark matter embedded in volatility and equity options? They consider a theoretical approach that allows them to introduce the constructs of risk premiums on jumps crossing the strike and on local time.
