deflationary trap/liquidity trap - orthodox monetary policy w austerity = stagnation. & west is exporting deflation. // if it is good for consumers ... break up banks. // hedging is BS ... you double the system you double the risk. [...] banks are now bigger! ... ban most derivatives, and reintroduce glass stegall // Black-Schoeles - there is no such think as risk free rate and no such thing as the past reflect the future. risk is not equally distributed. [...] VAR is flawed. //

BBC News - Black-Scholes: The maths formula linked to the financial crash
It's not every day that someone writes down an equation that ends up changing the world. But it does happen sometimes, and the world doesn't always change for the better. It has been argued that one formula known as Black-Scholes, along with its descendants, helped to blow up the financial world.

...

My Educated Take:
Black-Scholes worked as long as not everyone starts to use it. As everyone starts to use it (excluding deviations) - it becomes worthless.
Black-Scholes is also ONLY one of the many puzzles that led to the GFC (2008)

Nassim Taleb on JPMorganChase +2bn quartely loss by London unit - YouTube
Nassim Taleb argues:
- losses arise bc the math didn't work (( the model, risk metrics, too complex as the world can be )), simplifies fact - naming theses people incompetent.

- argues that investment banking needs to be split up from retail, investment banks need skin in the game - traders need skin in game - like hedge funds.

The mathematical equation that caused the banks to crash | Science | The Observer
The Black-Scholes equation has its roots in mathematical physics, where quantities are infinitely divisible, time flows continuously and variables change smoothly. Such models may not be appropriate to the world of finance. Traditional mathematical economics doesn't always match reality, either, and when it fails, it fails badly. Physicists, mathematicians and economists are therefore looking for better models.

At the forefront of these efforts is complexity science, a new branch of mathematics that models the market as a collection of individuals interacting according to specified rules. These models reveal the damaging effects of the herd instinct: market traders copy other market traders. Virtually every financial crisis in the last century has been pushed over the edge by the herd instinct. It makes everything go belly-up at the same time. If engineers took that attitude, and one bridge in the world fell down, so would all the others.
