What changes must be made in aggregate supply and demand to create economic growth?

To foster economic growth, aggregate demand can be stimulated through increased consumer spending, government investment, and export growth, which can be achieved by lowering interest rates or implementing fiscal policies. On the supply side, enhancing aggregate supply may involve investing in infrastructure, improving workforce skills, and adopting new technologies to increase productivity. Additionally, reducing regulatory barriers can encourage business investment and innovation. Together, these changes create a more favorable environment for economic expansion.
