Investment and consumption | GDP: Measuring national income | Macroeconomics | Khan Academy
Summary
TLDRThis video script delves into the concepts of investment and consumption, contrasting their everyday meanings with their economic definitions. It explains that while everyday investment is about activities for future gain, like building a house or education, economics narrows it to capital equipment, inventory, and new structures. Consumption in daily life refers to short-term use items like eating a candy bar, but economically, it's spending on final goods by households, excluding new homes. The script aims to clarify these terms for understanding GDP composition.
