Professor Metcalf has expert insight into the importance of federal tax policy for shaping energy investment policy in the United States. In March, he testified before the House Ways and means Committee during hearings on price volatility of climate change legislation. Here's a link to the hearing: http://waysandmeans.house.gov/hearings.asp?formmode=detail&hearing=668. It may be good background material.
His testimony covered several key points:
* Factors that cause price volatility
* The effect of cost containment provisions
* The advantages of implementing a carbon tax using the existing
tax structure of the Internal Revenue Service
In addition, he testified before the Senate Finance Committee in April on energy technology neutrality.
