Hubert is a stay-at-home parent who lives in New York City and teaches tennis lessons for extra cash. At a wage of $35 per hour, he is willing to teach 4 hours per week. At $45 per hour, he is willing to teach 8 hours per week. Using the midpoint method, the elasticity of Jake’s labor supply between the wages of $50 and $65 per hour is approximately ___ , which means that Jake’s supply of labor over this wage range is ___ .

Answer and Explanation:

The computation of the midpoint elasticity is as follows;

Midpoint elasticity

= (Change in labor supplied ÷ Average labor supplied) ÷ (Change in wage rate ÷ Average wage rate)

= [(8 - 4) ÷ (8 + 4) ÷ 2] ÷ [$($45 - $35) ÷ $($45 + $35) ÷ 2]

= [4 ÷  (12 ÷ 2)] / [$10 ÷ ($80 ÷ 2)]

= (4 ÷ 6)  ÷ ($10 / $40)

= 0.67 ÷ 0.25

= 2.68

As the elasticity is more than 1 so the supply of labor should be elastic

O a key ethical issue

Explanation:

In the process of gathering data for analysis, it is very important that certain ethical standards are adhered to. One of these very important ethical requirements is making sure that there is consent from the individuals whose data is to be used. Individuals have a right to their privacy. Using data or information about them for whatever purpose without them approving of it is a breach of privacy and might incur lawsuits if they get to know about that.

To prevent such issues from arising, the intent of the analyst should be clearly disclosed and the approval of the informant obtained.
