Determinants of demand elasticity

Determinants of demand elasticity?

J/k I didn't know so I looked it up.

Determinants of Demand

The major nonprice determinants of demand are: (1) income, (2) tastes and preferences, (3) the price of related goods, (4) changes in expectations of future relative prices, and (5) population (I.e., market size). The major nonprice determinants of supply are: (1) input costs, (2) technology, (3) taxes and subsidies, (4) expectations of future relative prices, and (5) the number of firms in the industry.

Substitutes: a change in the price of one causes a shift in demand for the other in the same direction (e.g. butter and margarine)

Complements: a change in the price of one good causes a shift in demand for the other in the opposite direction (e.g., stereo amplifiers and speakers, nuts and bolts)

Distinguish between Changes in Demand and Changes in Quantity Demanded

Change in Demand—results from change in a non-price determinant of demand (curve moves)

Change in Quantity Demanded—results from change in price (move along curve)
