A new relation requires a fresh assumption. Perhaps the simplest we can make is that the economy retains a constant proportion , σ, of output for it s capital stock.

Notice from Fig. 6 that the short-term dynamics appears cyclic. 46). We might regard the short-term model as imbedded in the long-term one. 47) xn+l = B(yitb)), where y denotes pollution within a time unit and appropriate functions A, B, and g are to be defined. 47) is independent of n. 8 Salmo n Dynamic s 23 then t - t = 1 - f, - c . 47).
