Supply and Demand
Supply and demand curves only shift right or left
Quantity demanded rises as price falls
Substitution effect: price changes relative to another similar good
Income effect: change in price effectively changes disposable income
Demand can shift for many reasons, substitutes, income, demographics, consumer tastes, etc.
Qd=a-b(P)
Quantity supplied increases with price
Qs=c+d(P)
Supply can shift when productivity increase, costs decrease, etc.
Equilibrium - NO PRESSURE TO CHANGE PRICE
Surplus vs. Shortage
Break Even - Marginal Cost=ATC - where marginal cost equals change in total cost/change in quantity & ATC = TC/Q
Elasticity
Sensitivity of demand due to price changes
Ep=(%changeQ)/(%changeP) Elastic if E>1elastic, less than 1, means inelastic. Basically, if something is elastic, it means customers are price sensitive. You will make more money with a decrease in price. In this case, there are a lot of substitutes. An inelastic product has customers that are not price sensitive. If you cut the price, you’re leaving money on the table.
Other elasticities; income, arc, cross/price, etc. Price elasticity of supply basically a percentage change in quantity that comes from a 1% change in price.
