Finally, something I was able to hint at in the profile. ![]() (For extra credit, reconcile this observation with the fact that chaotic systems are generally ergodic, though "subject to positive destabilising feedback".)ĥ. The rest of you, go back to the books and revise. "Sir, you can't work out the answer to that question in any statistically reliable manner, sir, because economic processes are nonergodic, sir, because the economy is subject to positive destabilising feedback sir!" When Scholes started talking about how finance needed to embrace non-stationary processes, it was all I could do to not quote D-Squared at him: But when you make a list of all the over-simplifications that go into deriving the formula, you have to ask whether it relying on it is ever a good idea.Ĥ. Presumably somebody has modified it to include a finite risk of default (though estimating that risk would be tricky at best see below). Obviously, the problem is that the Black/Scholes/Merton argument assumes the company you're buying stock in will persist indefinitely into the future. Could she have hedged away the risks of that stock by suplementing it with the right number of WebVan options? The question answers itself stuffing the money under her mattress would've had better risk/return properties. Back in the day, one of my in-laws bough stock in, and has made a return to date of -100% they're so belly-up I can't give you a link. Black-Scholes portfolios, combining stock and options in just the right proportions, are supposed to be riskless. I did not have the gumption to ask what it felt like to lose several billion dollars over a summer, or if it was true that when LTCM was raising capital, he'd respond to skeptics by saying they'd make money "because of fools like you".ģ. He was understandably completely bored by the idea of discussing the origins of the Black-Scholes formula yet again other topics interested him more.Ģ. He's pretty clearly the second most arrogant of the five, though also pretty clearly not the smartest, or even the second smartest. Scholes is the fifth Nobel laureate I've had a chance to talk to at some length. (If you don't know who Scholes is, well, read my piece!) Here then a few reflections which it wouldn't have been appropriate to work in to the profile.ġ. The latest of these came from an editor at Quantitative Finance, and led to my conducting a telephone interview with Myron Scholes and writing a profile of him for QF. ![]() Additionally, as pygmy sloths have become more widely recognized internationally, there is growing interest in collecting them for captivity.I am generally receptive to (legal) propositions which involve my receiving sums on the order of my paycheck in exchange for a few days of work. Ongoing disagreements between the local Ngäbe bugle Comarca, regional politicians, and the Panamanian government are further complicating long-term protection of the island and the pygmy sloths. The current status of the island’s custody is vague a governmental resolution, and thus the protected status of the island, cannot be revoked, but no government staff has been appointed specifically to enforce protection of the island. This includes plans for an eco-lodge, a casino, a marina, and a banking center. Despite having been designated as a protected landscape through a governmental resolution in 2009, a number of domestic and international efforts have been mounted to develop tourism infrastructure on the island. These results highlight the need of a continuous evaluation of the population status, trends, and additional studies considering a possible scenario of endogamic depression if the (already low) population size decreases any further. ![]() However, signs of a more recent population bottleneck were also detected. This is expected, considering the history of species diversification and isolation on the island. Preliminary studies suggest a reduced level of genetic diversity for pygmy sloths compared to its putative population of origin, the common sloth population from mainland Panama. Although the island is uninhabited, there are seasonal visitors (fishermen, campesinos, lobster divers, tourists, and local people) who harvest timber to maintain wooden houses on the island.
