A movie theater is showing two different movies: a Hollywood blockbuster (with 100 customers willing to pay $10 for a ticket, and 100 willing to pay $8) and an independent film that attracts 50 film buffs, willing to pay $20 each. Marginal costs are zero and neither movie can fill theater capacity. What is the theater's maximum profit if it cannot price discriminate (it must charge the same price for both movies) and if it can price discriminate (it may charge different prices for different movies)?
a. $2,000; $2,600
b. $1,500; $2,100
c. $1,500; $2,000

5. Download the Excel sheet from Brightspace. The data contains the GDP per capita and GNI
per capita of OECD member countries in 2014 (both figures are reported in US dollars). The
countries are ranked by GDP per capita.
a. Compute the ratio of GNI to GDP for each country (GNI per capita/GDP per capita). What
does this imply about net factor income from abroad for each country?
b. Rank the countries based on the GNI/GDP ratio, starting with the country with the highest
ratio and ending with the country with the lowest ratio. Which country has the highest ratio,
and which has the lowest?
c. Comment on why the countries you identified in the previous question have a large
difference between GDP and GNI? What does the difference imply?

Compute the "change" in external wealth at t+1 for Home. b. A country's external wealth was -$1.5 billion at the end of 2015, and its trade balance was $750 million in 2016.

Assume that a country produces an output Q of 50 every year. The world interest rate is 10%. Consumption C is 50 every year, and I = G = 0. There is an unexpected drop in output in year 0, so output falls to 28 and is then expected to return to 50 in every future year. If the country desires to smooth consumption, how much should it borrow in period 0? What will the new level of consumption be from then on?arrow_forward
- 2. Show how each of the following would affect the following US balance of payments: trade balance (TB), net factor income abroad (NFIA), net unilateral transfers (NUT), financial account (FA), and capital account (KA). Identify which specific account is affected in each case (e.g., +$10 in TB). Note that the sum of the balance of payment accounts is zero. Example: A California computer manufacturer purchases a $50 hard disk from a Malaysian company, paying the funds from a bank account in Malaysia. Answer: The US imports a hard disk from Malaysia: TB = $50 The US draws a foreign asset to pay for the import (less external asset): FA = +$50. (Note: The balance of payment identity holds: CA + FA (+KA) = −- $50 + $50 = 0. No KA in this example.) a. A US tourist in Japan sells his iPod to a local resident for yen worth $100. (hint: A US tourist obtains Japanese currency.) b. A US owner of Honda shares receives $10,000 in dividend payments, which are paid into a Tokyo bank. c.
