Core Concepts of Macroeconomics

Skibidi to the world of macroeconomics, where goons analyze the whole economy like sigma brains. It is all about those dank aggregates: production, employment, investment, and consumption. Lowkey, they try to figure out what factors influence these macro variables and how they interconnect. Aggregation is the move, blending micro data into macro insights. But be careful, because measuring them can be tricky. Nominal vs. real production is a whole edge case. GDP shines as the star player, showing the flow of new products and services, but counting it can be a total toilet mess. Paul Samuelson knew it; without GDP, we are lost.
