If there are two groups of workers in a competitive labour market, and one group becomes discriminated against, the labour supply curve for jobs that remain available for that group will shift to the _____ (right/left) and the wages for these jobs will _____ (decrease/increase).

If there are two sets of workers in a competitive labor market, with one group discriminated against, the labor-supply curve for the available jobs will move to the left, and the wages for these jobs will increase. Change in supply due to the switch on competitors' numbers in the market will cause an imbalance in the market, but can get corrected by shifting the demand and prices. A decrease in supply shifts the supply curve to the left; necessarily, there is a decrease in the number of workers available; thus, it will be paired with increasing the market's job wages. The discrimination of one job group put that group out of the market, making the other job group be on demand. Because the need is constant, the supply experiences a negative shift to the left. Employers will have to raise the wages of this particular job group to attract workers to their entities.
