Is it me, or is Professor Mankiw simply asking economists if they have engaged in the practice of popular, mainstream economics?
- Building models one does not really believe to be useful or relevant.
- Making simplifications that obscure or omit important things.
- Using data one does not really believe in.
- Focusing on the statistical significance of one’s findings while quietly doubting economic significance.
- Engaging in data mining.
- Drawing “policy implications” that one knows are inappropriate or misleading.
- Keeping the discourse “between the 40 yard lines” so as to avoid being outspoken; knowingly eliding fundamental issues.
- Tilting the flavor of policy judgments to make a paper more acceptable to referees, editors, publishers, or funders.
- Disguising one’s methodological or ideological views, such as by omitting revealing activities or publications from one’s vitae.
- For government, institute, or corporate economists: Having to significantly play along with things one does not believe in.
Aren't these activities the cornerstone of modern, popular economics?
