Economy of skill
“Economy of skill” is a terminology that I invented when I see in a statistics that an more experienced tax preparer charges less on certain forms than a novice. I was surprised at first, but later realized that those who are proficient will not find a task difficult and hence tend to charge a lower fee for what appears to be an easy job to her, while those who lack skills or knowledge will struggle and find it justified to charge a higher fee.
