Harrod-Domar model
The Harrod-Domar model explains how the income of today affects the income of tomorrow in a simple equation where the data entries are minimal. Although the Harrod-Domar model is easy to use, there are a few limitations. The economy only enters equilibrium when there is a full employment of both labor and capital. Using the fixed-coefficient production function, the capital-labor ratio must remain constant. On a graph, with capital on the y-axis and labor on the x-axis, we can illustrate all the different combinations of capital and labor that equal the same income through L-shaped isoquants. In order to be at full employment, capital and labor must grow at the same rate, which is unlikely. First, capital stock must grow at the same rate as output, which implies constant growth at full employment of capital. The capital stock to output ratio (v) is capital stock divided by output, where the variables grow at the same rate. Output grows at a rate of g; therefore, capital stock must be growing at the same rate. If we apply the above logic to labor, the population must be growing at same growth rate, g. Now what if the labor force is growing too fast, where n
