Figure 4.
Lifetime production effects of pedagogy. Lifetime production (PT*, y-axes) is shown for activities differing in strength and skill requirements, across a range of ages of teacher onset (b, x-axes) and with teacher handicaps (φ) ranging from 1 to 10% with a strong pupil boost (θ = 100%) and early pupil onset (a = 10). Solid lines show results for low-skill activities and dashed lines show results for high-skill activities. Bold dashed black line is the break-even threshold (PT*/PT = 1). (Online version in colour.)
