Answer to Question #76131 in Economics for JMila

Question

Jean Baptiste Sey a Frenchman economist from early nineteen century is credited with stating “supply creates its own demand.”Today some economists appear to argue that “demand creates its own supply” Explain why neither statement is precisely correct, and how demand and supply together create the market for goods and services

Answer 1

Supply does not create its own demand, if the demand for the certain goods is satisfied and the market is already oversaturated. Not every unit of goods supplied is sold.
Demand also does not create its own supply, if there is no available resources/technologies/opportunities to produce at the reasonable price. Not every unit of goods required can be bought.
Market makes the balance between consumers and producers, when the equilibrium price and quantity are set up.
