The first one is the basis of the neoclassical theory of economic growth, the Solow model which deals with the exogenous growth. The second model is from Keynes. The third one is the Harrod-Domar model which is the basis of the Postkeynesian theory of economic growth and the last model deals with the endogenous growth and forms the basis for the new-classical theory of economic growth. In the following four different models are indicated with the help of the method of the literature-based analysis. In every economic development model the origin, the acceptances and the criticism are performed and the frame of this work is not enough to give every derivation. In the end the result summarizes this housework.
