The Solow–Swan model or exogenous growth model is an economic model of long-run economic growth. It attempts to explain long-run economic growth by looking at capital accumulation, labor or population growth, and increases in productivity largely driven by technological progress.

WebPart (a) tells us that k1 = 112.5. We can use the Solow growth model equation to calculate k2: k2 = (1 - d)k1 + sY1/L. where s is the savings rate, Y1 is output per worker in period 1, L is labour force, and d is the depreciation rate. Part (c) tells us that Y1 = 9.769. Solow assumed a very basic model of annual aggregate output over a year (t). He said that the output quantity would be governed by the amount of capital (the infrastructure), the amount of labour (the number of people in the workforce), and the productivity of that labour. He thought that the productivity of labour was the factor driving long-run GDP increases. An example economic model of this form is given below:
