This is mostly microeconomics stuff, but for a national economy. Macro is when the scale of a market causes it to obey different rules, sort of how quantum mechanics is fundamentally different from classical but quantum particles still obey classical laws in some situations. Micro is a lot easier to work with because you can study it empirically, since experiments and data can be assumed to scale up; it's subject to the "rigorous analysis" you talk about.
