more on shadow price following yesterday's discussion

[Anne Hendry <ahendry@pacbell.net>]

I came across a document with a good clear description (to my mind) of 
shadow price and it's relationship to balancing price and congestion 
pricing: www.ercot.com/content/mktinfo/prices/MCP.pdf

Also from the UK Dept. of Energy, interesting document detailing their 
rationale to move from using 'Social Cost of Carbon' to 'Shadow Price of 
Carbon' in determining policy and economic investment appraisals:

Best,
