I have a bachelors degree lower second classification 2:2 in Economics. Specialising on macro nomics is about allocating scarce resources which have alternative uses. Economics is about consumer choices and the budget constraint that consumers have. Macro economics is about full employment or full capacity where resources and the resources in the economy are operating at full capacity. We use interest rates or money policy to reduce prices and fiscal or taxation and government spending to free up consumer demand and this helps to free up resources so we are operating at full capacity or less because once full capacity is reached resources are no longer available so prices rise because there is excess demand so we use fiscal and monetary policy to return to drive prices down to reduce demand and return to full capacity or lation is the rise in the general price level.
