alternative for you is to work during the summer in your hometown. For you
decision-making analysis you have come up with the following information: Summer job in your hometown pays $8,000 for the entire summer. If you work in summer you can eat with you parents for free. Unpaid internship in New York will increase your lifetime earnings by $9,000.
You expect to derive an enjoyment worth of $2,000 while living in New York.
It will cost you $400 in airfare to get to New York from your hometown. V‘VVVVV You will need to spend $900 on food while in New York the entire summer. a. In a table below please summarize all the relevant private expected marginal costs and
beneﬁts of the unpaid summer internship. Hint: Every term in the following table should
have a speciﬁc monetary value. For example, you may want to write “Airfare $400”
under Private expected marginal costs. Frigate expected marginal costs . Private expected marginal beneﬁts

Airfare $400 Unpaid lnternship $9,000
Food $900 Total: 5%0 1 Total: 517% b. Based on the table above, what would be a rational decision? Please brieﬂy explain
how you derived this conclusion. The rational decision would be to go to the unpaid internship in New York rather than staying
home and working at the summer job because the estimated surplus was $13,700. Econ 1014 Principles of Microeconomics Summer 2012 c. Now suppose it’s the end of the summer and you evaluate your decision. It turned out
that surmner job in your hometown was paying $10,000 for the summer and you didn’t
enjoy your time in New York that much; you derived only $1,000 worth of enjoyment.

your lifetime. Use the table below to summarize social marginal beneﬁt and costs of your
decision. Based on the table below, what is the best decision for society and why? Again, please
label all the monetary values in the table. Social actual marginal costs Social actual marginal beneﬁts
