Economists use models as the primary tool for explaining or making predictions about economic issues and problems.

In Harrod s model, if incremental capital-output (v) actually realised happens to be equal to required capital-output ratio (v r), warranted by technological and other conditions, then the actual rate of growth, G y is equal to the warranted rate of growth (G w), the rate which the circumstances of the economy warrants, the economy will be growing at the equilibrium rate (G y = G w).

Lara Frisch looks at 5 alternative economic models that can be applied at a community level. capital-output ratio and labour-output ratios are constant.

Domar Model has explained the conditions which need to be satisfied to attain the given goal. He also explained the conditions that need to be fulfilled to maintain this steady growth rate. The Domar model has tried to explain that what should be the growth rate to maintain full employment equilibrium in the economy? The rst model that we will look at in this class, a model of economic growth originally developed by MIT’s Robert Solow in the 1950s, is a good example of this general approach. When G = Gn, there will be full employment of resources.

The assumptions of the Domar Model are as follows: Sufficient investment is required to attain dual objective: Harrod Model and Domar Model differ in details, but the ideas contained in both of the models are so similar that the two models have got integrated and more generally are presented as a single united model, known as the Harrod-Domar Model (HDM). The Exogenous growth model, also known as the Neo-classical growth model or Solow growth model is a term used to sum up the contributions of various authors to a model of long-run economic growth within the framework of neoclassical economics [3]. There is a strong probability that in the long run it will ride above Gn and if so happens there will be vicious spiral of depression after attainment of full employment level.
