Zitat des Tages von Myron Scholes:
A bank needs models to measure risk. The problem, however, is that any one bank can measure its risk, but it also has to know what the risk taken by other banks in the system happens to be at any particular moment.
Every side of a coin has another side.
All models have faults - that doesn't mean you can't use them as tools for making decisions.
Innovation must lead infrastructure for a simple but compelling reason: Innovation produces new types of products and markets, and it is virtually impossible to know how to run those markets efficiently before they are created.
Sometimes the early bird gets the worm, but sometimes the early bird gets frozen to death.
Keynesian modelling relies on marginal propensity to consume and marginal propensity to invest. The idea that if we give more money to the poor, they have a propensity to consume that's much higher than the wealthy, though I wish they would talk to my wife about that; she seems to have a propensity to consume.
I think in our global economy, uncertainty is ever increasing. So to accommodate to that, we need to build a dynamic economy and dynamic rules that can adapt to changing circumstances.
A futures contract is a derivative, but the futures exchange doesn't call them 'derivatives,' they call them 'futures.'
My view is that one should diversify broadly across different fund investments. However, it's tough for investors to try to pick the appropriate risk level that they should manage their funds at. Having a personal adviser would be helpful.
I'm a theorist, not an institutionalist.
