Explanation of Solution
The slope of the linear equation is the MPC; here, it is equal to 0.8. Thus, MPC is 0.8.

- Problem 2 Experiments/Randomized Control Trial Suppose you are interested in studying the effect of academic counselling on the years it takes for a student to obtain an undergraduate degree. You conduct a randomized control trial to answer the question. You randomly assign 2500 individuals in a university in New York to receive academic counselling and 2500 students to not receive any academic counselling. a. Which people are a part of the treatment group and which people are a part of the control group? (5 points) b. What regression will you run? Define the variables where required. (5 points) Λ c. Suppose you estimate ß₁ = -0.3. Interpret it. (5 points) 1 d. You test for balance using the variables mentioned in the table below. Based on the results do you think that the treatment and control group are balanced? If your answer is "yes" then explain why. If your answer is "no", then explain why and mention how will you address the issue of imbalance.

You collect data on 1000 people and run the following regression. Wage=Bo+B₁Labor Union; + &¿ where Labor Union is a dummy variable which is equal t to 1 for people who are a part of labor union and 0 for others. a. Suppose you estimate b. Do you think B₁ = 1.6. Interpret B₁ (5 points) 1 1 is biased or unbiased? Explain. (5 points) Now suppose you conduct a randomized control trial to answer the same question. You randomly assign some individuals to be a part of the labor union and others to not be a part of the labor union. The first step you take is to ensure that the randomization was done correctly. Then you estimate the following equation: = Wage, Bo+B₁Treatment; + &; Treatment =1 if the student is assigned to be a part of Labor Union Treatment=0 if the student is assigned to not be a part of Labor Union c.

Properly label this line. Part 2 Note: Carefully follow the instructions above and only draw the required object. Part 3 Which of the following will generate a decrease in aggregate demand? A. Increased government expenditures for infrastructure. B. A tax increase. C. An increase in the price level. D. An increase in the money supply.arrow_forwardA 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; $2,000arrow_forwardA 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.

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?

In t+1, Home purchases $160 million foreign assets, and Foreign purchases $120 million in Home assets. Assume a world interest rate of 10% per annum. 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.

- 1. The table below shows a country's hypothetical national income and product accounts data. Category Consumption (personal consumption expenditures) Investment (gross private domestic investment) Government consumption (government expenditures) Exports Imports Net Factor Income from Abroad Net unilateral transfers Billions of Dollars 8,000 1,300 2,100 900 1,750 +45 -20 a. Compute the following accounts using the information in the table: Gross national expenditure (GNE) . Trade balance (TB) • Gross domestic product (GDP) • Gross national income (GNI) . Gross national disposable income (GNDI) Current account (CA) b. Derive the current account identity using the national income identity. Are savings greater than or smaller than investment in this country? The national income identity is: GNDIGNE + CA, GNE = C + G + I.arrow_forward4. 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_forward2. 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.
