The simulation starts in equilibrium. To see the effect of exogenous changes in the starting population N, the wage function w(N), the birth function b(w), or the death function d(w), move the slider and hit the 'play' button the time slider.
For example, move the N slider to '8', hit 'play', and watch the economy and population return to the steady state wage level with population '5'
