A brain drain hollows out the knowledge base

What moves on the Endogenous Growth (AK Model) diagram

  • Saving s·A·kshifts down (small)

Losing skilled people lowers A, rotating the saving line down and permanently narrowing the growth gap: the mirror image of an innovation boom.

Step by step

  1. 1

    Growth runs on the productivity of ideas and skills: the A in AK.

  2. 2

    Skilled workers and researchers emigrate en masse.

  3. 3

    The saving line rotates down toward break-even.

  4. 4

    The growth gap narrows permanently, and if A falls far enough the economy can stagnate outright. Human capital flight is a growth-rate problem, not a one-off loss.

Where this shows up

Examiners ask this as: brain drain, emigration of skilled workers, talent exodus, researchers leave, human capital flight.
