Supply and Demand:
Supply and demand are two very important economic concepts. Regardless of the kind of market it is argued that factors affecting the two lead to the determination of the price. Supply is the quantity of a product or service available within the market in question while the demand refers to the quantity of the good or service that is demanded within an existing market.
Macro economics is a sub-field of economics. This sub-field concerns itself with aggregates within the economy. There are many macroeconomic indicators. Among the most notable are: gross domestic product (GDP), the rate or level of unemployment, inflation, national income, retail volumes, consumer credit and the consumer price index.
Unlike microeconomics that concentrates itself with operations of single entities within different industries macro-economics concerns itself with the total performance of the entire economy.
