I think (macro) econ is a lousy tool for measuring happiness. Micro might be. Now, some parts of the various econs - like the theory of revealed preferences* - may well be useful in measuring or talking about happiness but taken as a while, it is IMO incumbent on economists to be humble about this. *which teaches us that what people say and what they do are two very different things.
