Chapter 9 further develops economic evolution powered by informational selection. We observe that in economic evolution, institutions play an important role, and many new issues not encountered in Natural Selection appear. Economic evolution often does not take place by pure selection (choosing or eliminating), but by building an elaborate institution. For giant institutions such as global platforms, the numbers from which to choose are probably very few, but selection is nevertheless always present, as it operates on the smaller units. An important barrier against informational selection is communication costs, which steadily trend downwards and include collecting, transmitting, ranking, sorting, filtering, and analyzing.
