Question 1
- Labor-hours is the input NOT the output
Labor-hours | Fish | Wheat |
---|---|---|
Country A | 10 | 20 |
Country B | 20 | 60 |
- Convert to the quantity of outputs, assuming the labor-hours is 60
Quantity | Fish | Wheat |
---|---|---|
Country A | 6 | 3 |
Country B | 3 | 1 |
Country A has CA in wheat
Country B has CA in fish
Question 3
In a inflationary gap, the following occurs
An initial positive demand shock (real estate market booms)
AD shifts to the right, and so the aggregate price level and aggregate output increase, which leads to higher inflation in the short-run and reduces unemployment
Eventually, an increase in nominal wages in the long run decreases the SRAS and moves the economy back to potential output
Contractionary Fiscal Policy
Use contractionary fiscal policy to decrease aggregate demand in order to get the economy back to its potential output
Decrease government spending (direct impact)
Increase taxes
Decrease in government transfers

Question 4
Crowding-out effect
- When the government borrows funds in the financial markets, it competes with private firms and "crowds out" private spending by raising interests rates and reducing long-run economic growth
Question 5
MPC + MPS = 1
Question 6
Government Spending | Money Multiplier | |
---|---|---|
Taxes | Tax Multiplier |
- When raising government spending and the taxes by the same amount, the impact of government spending will be greater than that of taxes
Question 7
Expansionary Monetary Policy | Contractionary Money Policy |

Question 9
Expansionary monetary policy → r↓
Expansionary Fiscal Policy → Spend more money → Crowding-out effect → r↑
Expansionary policy will shift AD to the right, increase the GDP, therefore unemployment will decrease
Question 10
- Sell securities = Shrink money supply = decrease total loans by banks
Question 11
- If the reserve ratio is low, more money circulate, so Fed will have more effect on rGDP
Question 12
Labor productivity↑ → AS↑ → Price Level↓ & rGDP↑
Question 14
Phillips curve
x-axis: unemployment rate
y-axis: inflation rate
Short-run Phillips curve
Long-run Phillips curve
In short-run
High inflation rate, low unemployment rate
Low inflation rate, high unemployment rate
Question 16
Question 17
The equation of exchange
MV = PY
Expenditure = nominal GDP
M: money supply
V: velocity of circulation
P: price level
Y: real GDP
Velocity of circulation
- the average number of times each dollar is spent on final goods and services
Question 18
Expansionary fiscal policy | Contractionary monetary policy | |
---|---|---|
GDP | ↑ | ↓ |
Unemployment | ↓ | ↑ |
Interest rate | ↑ | ↑ |
Question 19
- Supply of money ↑ = Value of money ↓ = Exports ↑
Question 20
Inflation rate > 0: inflation
Inflation rate < 0: deflation
