When unions set wage rates ---above--- market clearing prices, they face the problem of---rationing-- a restricted number of jobs to workers who desire to earn the higher wages. Unions may pursue any one of three goals: (1) to employ ---all--- union members, (2) to maximize total ---income--- of the union's members, or (3) to ---maximize--- wages for certain, usually high-seniority, workers. Unions can increase the wage rate of members by engaging in practices that shift the union labor supply curve ---inward--- or shift the demand curve for union labor ---outward-- (or both).

Demand curves are drawn with determinants other than the price of the good held constant. These other determinants, called ceteris paribus conditions, are (1) --income--, (2)-- tastes and preferences--, (3) --prices of related goods--, (4) --expectations about future prices and incomes--, and (5) --the number of potential buyers-- in the market at any given price. If any one of these determinants changes, the demand curve will shift to the right or to the left. A change in demand comes about only because of a change in the --ceteris paribus-- conditions of demand. This change in demand is a shift in the demand curve to the left or to the right. A change in the quantity demanded comes about when there is a change in the price of the good (other things held constant). Such a change in quantity demanded involves a --movement along-- a given demand curve.
