Answer to Question 1

b

Answer to Question 2

There are at least two reasons. One is that the elasticity of substitution between skilled workers and other factors of production is low; thus firms cannot substitute some other factor of production if wages rise. Secondly, skilled labor is likely to be a relatively small percentage of total costs, and thus raising wages does not cause a large increase in total costs (which would lead to a reduction in supply, an increase in price, and a decrease in output). Unskilled labor has more substitutes and is likely to be a larger share of costs for firms that employ it, and thus if unions raise wages, firms employ other factors of production, and many workers will be laid off.
