Demand, Supply And Market Equilibrium
Visão Geral
Nobody sets the price of a banana at a market stall by committee. Buyers and sellers, each acting purely in their own interest, push the price up and down until it lands at the one figure where every buyer willing to pay finds a seller willing to sell, and every seller willing to sell finds a buyer. That self-correcting process is the heart of market economics.
In this lesson you will build the demand curve and the supply curve from first principles, learn the crucial difference between a movement along a curve and a shift of the whole curve, and put both curves together to find equilibrium price and quantity. You will also learn to identify and remove excess demand and excess supply, the two states a market falls into whenever price sits away from equilibrium.
Objetivos
- Definition of demand
- The use of demand curve diagram to show changes in price causing movements along a demand curve, and shifts indicating increased and decreased demand
- Factors that may cause a shift in the demand curve, including advertising, income, fashion and tastes, price of substitute goods, price of complementary goods, demographic changes
- Definition of supply
- The use of supply curve diagram to show changes in price causing movements along a supply curve, and shifts indicating increased and decreased supply
- Factors that may cause a shift in the supply curve, including costs of production, changes in technology, indirect taxes, subsidies, natural factors (natural disasters and weather)
- Equilibrium price and quantity and how they are determined
- The use of diagrams to show how shifts in supply and demand affect equilibrium price and quantity in real-world situations, excess demand, excess supply
- Define, calculate and draw excess demand and excess supply
- The use of market forces to remove excess supply or excess demand
