How is price formed/determined concerning Macroeconomics and the terms of shortage and surplus?
In macroeconomics price is known as General price level and its
determination depends upon the aggregate demand and aggregate
supply. Aggregate supply is an upward sloping curve an aggregate
demand is a downward sloping one. And their interaction determine
the output level in the economy and the overall price level
In microeconomics the concept of shortage and surplus arise.
Generally market is said to be in equilibrium when there is no
shortage or surplus so that there is no excess demand and excess
supply.
However there can be cases when the price in the market is higher
than the equilibrium and in that case there will be a surplus in
the market. This is because the quantity supplied by the suppliers
will be greater than the quantity demanded by the buyers.
At other times there can be shortages in the market when the price
level is lower than the equilibrium price so that the quantity
demanded exceeds the quantity supplied. Both of these conditions
are a case of short run and the market will reach its equilibrium
level in the long run.
