For nearly five decades, Colombia has been embroiled in internal armed conflict among guerrilla groups, paramilitary militias, and the country’s own military. Civilians in Colombia have to make their lives despite the threat of torture, kidnapping, and large-scale massacres—and more than four million have had to flee their homes. The oral histories in Throwing Stones at the Moondescribe the most widespread of Colombia’s human rights crises: forced displacement. Speakers recount life before displacement, the reasons for their flight, and their struggle to rebuild their lives. Among the narrators: JULIA, a hospital union leader whose fight against corruption led to a brutal attempt on her life. In 2009, assassins tracked her to her home and stabbed her seven times in the face and chest. Since the attack, Julia has undergone eight facial reconstructive surgeries, and continues to live in hiding. DANNY, who at eighteen joined a right-wing paramilitary’s enormous training camp in the Eastern Plains of Colombia. Initially lured by the promise of quick money, Danny soon realized his mistake and escaped to Ecuador. He describes his harrowing escape and his struggle to survive as a refugee with two young children to support.

The Author shows that modelling the uncertain cash flow dynamics of an investment project deserves careful attention in real options valuation. Focusing on the case of commodity price uncertainty, a broad empirical study reveals that, contrary to common assumptions, prices are often non-stationary and exhibit non-normally distributed returns. Subsequently, more realistic stochastic volatility, jump diffusion, and Levy processes are evaluated in the context of a stylised investment project. The valuation results suggest that stochastic process choice can have substantial implications for valuation results and optimal investment rules.
