All growth models mentioned emphasize the importance of saving rate in economic growth. So, there is a need for the government policies to improve the saving rates. Saving rate can be increased by raising the real interest rate. Increase in real interest rate encourages savers for saving. However, it should be noticed that the empirical study results show that the response of saving to changes in the real interest rate seems to be small. Another way to increase national saving is to increase government saving.
