11/8/10 2 a – Calculate the change in GDP n A family sells a home, without using a broker, for $150,000. They could have rented it on the open market for $700 per month. They buy a 10-year-old condominium for $200,000; the broker’s fee on the transaction is 6 percent of the selling price. The condo’s owner was formerly renting the unit at $500 per month. n a.

Similarly, the sales price of the home and the condo do not affect GDP, since these housing units were presumably produced (and counted in GDP) in some previous year. The sales commission on the condo—6% of $200,000 = $12,000—is the value of a currently produced service. Thus, GDP rises by $12,000 .

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
