For example, comparing small countries like Denmark with large diverse countries like the U.S. is intellectually dishonest. This is an example of personal bias, and most still credible economists are very aware of it. The U.S. has very different responsibilities in the world than very small and less diverse nations -- we have a unique place in the world. Denmark would not exist if not for the U.S. model -- neither would Europe. We would live in a totalitarian world. What would be the life quotient then? The models are literally incomparable. Paul did not suffer this type of bias when doing work that earned his Nobel or his brilliant forecasts on currency wars.
