The limitation of macro economics captured by the phrase 'what is good for an individual need not be good for the nation' is called:

1. The textbook lists four limitations of macro economics. 2. The first two are the danger of excessive generalisation of the economy as a whole, and the assumption of homogeneity among individual units. 3. The third is named the fallacy of composition: what is good for an individual need not be good for the nation and vice versa, and what is good for one country is not good for another or at another time. 4. The fourth is that many non-economic factors determine economic activity yet find no place in the usual macro economic books. 5. The other three options are real economic ideas but none of them is the term the book uses for this limitation. _Source: TN HSC Class 12 Economics (Samacheer Kalvi, Govt of Tamil Nadu), Ch 1 "Introduction to Macro Economics", §1.5_
