Article on Pools

The attached pdf file contains a paper written by Professor Wilson of
Stanford University. He is an economist who advised the California Power
Exchange and the California Independent System Operator on market design
matters. The paper compares the pros and cons of centralized versus
decentralized pools, comparing the California market to many other power
pools in the world. While it is a bit academic (and California-centric), it
is the best high-level characterization of pools that I have ever read.
