Q

What is Okun’s coefficient? How is it interpreted?

A

The slope of the regression line when the change in unemployment is regressed against the growth in real GDP. If the slope is shallow then there is little unemployment response to recessions, suggesting the fall in incomes from recession would be evenly shared across society

Net exports = exports - imports (net expenditure from abroad on domestic goods and services

18
Q

What is the output gap?

A

Percentage difference between actual output and the trend rate of output

19
Q

What is the exchange rate?

A

The price of a unit of domestic currency in terms of foreign currency

20
Q

What happens when the exchange rate appreciates?

A

It strengthens - you can get more of a foreign currency per one of the domestic currency

21
Q

What happens when the exchange rate depreciates?

A

The currency weakens - you can now purchase fewer of the foreign currency per one unit of the domestic currency

22
Q

What is the real exchange rate?

A

The ratio of the price of domestic goods to the price of foreign goods when expressed in the same currency

23
Q

What will happen to real exchange rate in the short-run when there is a change in the nominal exchange rate?

A

The change in the real exchange rate will perfectly reflect the change in the real exchange rate

24
Q

What is the effective nominal exchange rate? What is the effective real rate?

A

Product of the nominal rates for each trading partner weighted by their relative importance as a trading partner

For the effective real rate it is the same process for the price index of each partner

25
Q

What happens to net exports when the real exchange rate appreciates?

A

Price of domestic goods increases relative to foreign goods - > relative price of imports decreases which increases demand for imports -> domestic economy may stop producing substitutes for imports -> net exports decreases

26
Q

What happens to net exports when there is a depreciation in the real exchange rate?

A

Price of domestic goods falls relative to foreign goods -> relative price rises for imports pushing down demand for imports -> domestic economy may increase production of import substitutes -> increase in net exports

27
Q

What is the balance of payments? What is it equal to?

A

A sum of the current account, the financial account, the capital account and net erors/omissions. Equal to 0

28
Q

What is the primary current account?

A

Real exports - real imports

29
Q

For there to be a surplus on the current account what must the real exchange rate be?

A

Relatively low

30
Q

What is the inter-temporal budget constraint/solvency condition?

A

If a country runs a deficit in period 1, they must run a surplus in period 2 to pay off outstanding debt

31
Q

What is the relationship between the net international investment position (NIIP) and the real exchange rate?

A

Inverse relationship

32
Q

How is it possible for there to be large and persistent deficits?

A

They are financed by surplus nations - investing in deficit countries (buying foreign assets)

33
Q

What is absolute purchasing power parity?

A

In the long-run prices of domestic and foreign goods are equalized, when expressed in the same currency due to arbitrage

34
Q

What is relative purchasing power parity?

A

Changes in exchange rates reflect changes in domestic and foreign prices

35
Q

What is the Harrod-Balassa-Samuelson Effect?

A

The price of non-tradable goods are higher in rich countries due to productivity differentials between richer and poorer nations
