It is immediately obvious that population growth is inimical to sustainable development since it ‘dissipates’ the capital stock. Technological change, on the other hand, enables a given capital stock to generate more wellbeing per unit of the stock. An easy way to think of it, then, is to say that future generations will be no worse off if capital stocks are ‘constant’ and for the rate of technological change to just offset the rate of population growth. If technological progress is faster than population change, then future generations could still be as well off as we are today with a lower capital stock, and so on.
