3. Capital Stock and Investment: The amount and quality of physical capital (e.g., machinery, infrastructure, buildings) available for production, along with new investments in these areas, significantly boost a nation's productive capacity and income.
4. Technological Progress: Advancements in technology lead to more efficient production methods, new products, and increased productivity across industries, which are crucial drivers of economic growth and higher national income.
