I want to know the answer to the following question:
Who is the economist who said there was about $1.7 billion in lost opportunity costs because of the 2007 changes?
All the background I'm provided with is that "For example, a 2007 North American rule change cost an estimated $500 million to $1 billion, and Utah State University economist William F. Shughart II has estimated the lost opportunity cost at around $1.7 billion USD.". Is that enough to answer the question?
Answer: yes
