Why write a blog?

I have been working with financial firms for over 15 years. Financial firms are extremely sensitive to the accuracy of their pricing because each pricing error is replicated many times and feeds back directly into profit. As a consequence there has been an arms race of sophistication in their pricing algorithms.

Can these algorithms be used to price more accurately for those who want to maximize profit?

Could the world of e-commerce benefit from algorithms developed for Finance incorporating ideas from AI, Operations Research and Micro Economics?
