Noah Smith überlegt auf seinem Blog, warum Makroökonomen vielleicht nicht direkt aber indirekt von gesellschaftlichem Nutzen sind.
Nicht zuletzt, weil sie im Gegensatz zu anderen Wissenschaften so billig sind ...
"So, in short, from macroeconomists we get at least the following benefits:
1. Quantification of macroeconomic phenomena.2. Observation of correlations between macroeconomic variables (and between macroeconomic and microeconomic variables).
3. The creation of "spinoffs" like sVARs.4. The unknown potential for big breakthroughs in forecasting methods.5. An "anchor" that keeps policy away from the dangerous extremes urged on us by various politically-motivated fringe groups.
So without macroeconomists, it seems to me that we would lose quite a bit, actually. And since macroeconomists are very cheap, all in all, it seems we should keep them around."
