The Economic History Blog refreshes our memories on the various types of growth:
- The Solovian growth, after Robert Solow, which is driven by an increase of the saving rate leading to more investment and thus a jump of the production per unit of labor.
- The Smithian growth, after you know who, which is driven by the positive feedback between the gain from trade and division of labor (specialization).
- The Boserupian growth, after Ester Bosrup, when demographic expansion leads to positive size effects once some thresholds have been reach.
- The Schumpeterian growth, after Joseph Schumpeter, where an increase in the stock of knowledge applied to economic production leads to to the increase of the said production.
And the Visualizing Economics blog provides the visuals.
Now, this is a pretty good illustration of the taking the natural log of an exponential, I’d say.
