Both have to grow to increase output. You can’t just have one increase while other is constant Y is a function of a coefficient times K Coefficient is K/Y Binding constraint on function/production is capital If all we’re looking for is to get more machines, then you have to get MORE SAVINGS (according to our previous assumptions) Delta (Y) = delta(K)/v Growth rate (g) = change in output/current output = delta(K)/(Y x v) = (s/v) – d All you need to do is somehow get people to save more. Poor countries thought that they were poor though and there was no way for them to save. Richer countries saw this and said that this is a chance to begin financial aid.
