Answer: The quantity of labor increases, and the effect on the wage rate is indeterminate.
Explanation:
The supply of people who can make bicycles has increased at the same time the demand for bicycles has increased. The supply curve would therefore shift to the right and so would the demand curve for labor. They will intersect at a new point where the quantity of labor has now increased.
Unfortunately, the effect on the wag rate would be indeterminate because the wage rate might just stay the same on account of the supply increasing along with the demand instead of either of them increasing unilaterally. When tis happens, the change is said to be indeterminate.
