INCOME, DEMAND DETERMINANT: One of the five demand determinants assumed constant when a demand curve is constructed, and that shift the demand curve when they change. Income affects demand differently for normal goods and inferior goods. A normal good, the name indicates, is affected by income much as you might expect. Additional income allows buyers to purchase more normal goods, thus demand increases with an increase in income. The demand for an inferior good is affected exactly opposite. An increase in income causes a decrease in the demand for an inferior good. Buyers decide to buy less of an inferior good when they have additional income.

ARC ELASTICITY

The average elasticity for discrete changes in two variables. The distinguishing characteristic of arc elasticity is that percentage changes are calculated based on the average of initial and ending values of each variable, rather than initial values. Arc elasticity is generally calculated using the midpoint elasticity formula. The contrast to arc elasticity is point elasticity. For infinitesimally small changes in two variables, arc elasticity is the same as point elasticity.
