World Economy v. Poker??? Zero-Sum????

[crazy canuck]

Correct me if 'm wrong, but I think an option has an expected return that equals to the risk free interest rate in the Black-Scholes world, becasue everything has to be discounted. But even if it's true I have no idea if this applies in the real world.

PS: I haven't been drinking when I made the original post, but I've been drinking now. The restaurants have some good wine selection here in Montreal. [img]/images/graemlins/smile.gif[/img]
