Step by step

  1. 1

    Break-even investment covers wear-and-tear AND equipping new workers.

  2. 2

    Faster population growth steepens that line.

  3. 3

    More saving now goes to standing still; k* falls. More people, same machines, thinner capital each.

Where this shows up

Examiners ask this as: population growth dilution, capital per worker falls.
