I was told that there are really two broad categories of economic models in macroeconomics. These Being:
1)Neoclassical Growth Models
2)Overlapping Generations Models
All other models that exist are variants of these two. By explanation:
Neoclassical Growth Models include:
1)The Solow Model
2)The Ramsey Cass Koopmans Model
3)The AK/"Learning By Doing" Model
4)The RD Model (endogenous growth)
Overlapping Generations Models Include:
1)Diamond Overlapping Generations Model
2)The Samuelson Overlapping Generations Model
3)The Overlapping Generations Model with Money.
Is this really the case?
