Answer 4

The components of the BOP include equity capital, reinvested earnings, portfolio investment, financial derivatives, official reserve assets, and other assets and liabilities.

Question 5

What is the double-entry rule in the balance of payments?

Answer 5

The double entry rule in the BOP states that each transaction should enter into the balance of payments twice, with an increase in assets represented as a positive and an increase in liabilities as a negative.

Question 6

How do errors and omissions occur in the balance of payments?

Answer 6

Errors and omissions in the BOP can occur due to transactions not being registered simultaneously on both sides, some transactions being estimated, and others not being registered at all.

Question 7

Define Net Financial Account (NFA) in the context of the balance of payments.

Answer 7

The Net Financial Account (NFA) in the BOP
represents the difference between a country’s sales of assets to foreigners and its purchases of assets from foreigners.

Question 8

How does borrowing to finance a fiscal deficit contribute to the current account deficit according to the Twin Deficit Hypothesis?

Answer 18

Borrowing to finance a fiscal deficit, especially from foreign sources, can lead to increased capital inflows, contributing to a current account deficit.

Question 19

Describe the implication of higher interest rates on the current account deficit according to the Twin Deficit Hypothesis.

Answer 19

Higher interest rates resulting from heavy government borrowing to finance its fiscal deficit can attract foreign capital seeking better returns, contributing to capital inflows and, consequently, a current account deficit.

Question 20

Describe the absorption approach to Balance of Payments (BOP).

Answer 20

The absorption approach to BOP focuses on the total spending by domestic residents within an economy, encompassing consumption, investment, and government spending.

Question 21

Define the formula A = C + I + G in the context of the absorption approach to BOP.

Answer 21

The formula A = C + I + G represents the total absorption in an economy, where A is absorption, C is consumption, I is investment, and G is government spending.

Question 22

How is GDP related to absorption and net exports in the absorption approach to BOP?

Answer 22

GDP is equal to the total absorption (A) plus net exports (N), where net exports represent the difference between exports and imports.

Question 23

Do a relative decline in domestic spending compared to the overall economic output (GDP) favor an improvement in net exports in the absorption approach to BOP?

Answer 23

Yes, a relative decline in domestic spending compared to GDP can create conditions that favor an improvement in net exports and a more favorable trade balance.

Question 33

Describe the impact of a depreciated currency on imports and exports.

Answer 33

A depreciated currency means that imports become more expensive while domestically produced goods and exports become less expensive.

Question 34

How is a general trend in price competitiveness measured in terms of exchange rates?

Answer 34

A general trend in price competitiveness can be measured using the nominal effective exchange rate, which is a trade-weighted average of changes in exchange rates.

Question 35

Define the nominal effective exchange rate and its components.

Answer 35

The nominal effective exchange rate is a measure of the general movement (appreciation/depreciation) of a currency, calculated as a trade-weighted average of changes in exchange rates. It involves the number of competitor countries (N), the index of the exchange rate of the partner country (ei), and the overall trade weight assigned to the currency of the trading partner (wi).

Question 36

Describe the nominal exchange rate.

Answer 36

The nominal exchange rate is the rate at which one currency can be exchanged for another, representing the relative value of the two currencies in the foreign exchange market.

Question 37

Define the real exchange rate.

Answer 37

The real exchange rate is the nominal exchange rate corrected by price levels, taking into account the domestic and foreign price levels.

Question 38

How is the real exchange rate related to purchasing power parities?

Answer 38

The real exchange rate is a basic concept to both absolute and relative purchasing power parities, as it reflects the relative purchasing power of two currencies.

Question 39

Do the domestic and foreign price levels impact the real exchange rate?

Answer 39

Yes, the domestic and foreign price levels directly impact the real exchange rate, as it is calculated based on the nominal exchange rate and these price levels.

Question 40

Describe the effective exchange weights for the EU from 1995-2021.

Answer 40

The effective exchange weights for the EU from 1995-2021 refer to the weighted average of bilateral exchange rates of the euro against the currencies of its main trading partners, reflecting the importance of each partner in EU trade.

Question 41

Describe the real exchange rate and how differs from the nominal exchange rate.

Answer 41

The real exchange rate reflects the relative price levels of two countries' currencies, considering inflation differences, while the nominal exchange rate is the rate at which one country's currency can be exchanged for another's, without considering changes in the price levels.

Question 42

Define the real effective exchange rate (REER) and its significance in international trade.

Answer 42

The REER is a measure that assesses the value of a country's currency in relation to a basket of other currencies, taking into account differences in price levels between the home country and its trading partners. It is essential for understanding a country's international competitiveness in terms of trade.

Question 43

How is the real exchange rate calculated and what does a value greater than 100 indicate?

Answer 43

The real exchange rate is calculated by multiplying the nominal exchange rate by the ratio of the domestic price level to the foreign price level, typically expressed as an index number. A value greater than 100 indicates that the domestic currency is overvalued compared to the foreign currency.

Question 44

Do changes in the real exchange rate measure the price competitiveness of one country compared to another?

Answer 44

Yes, changes in the real exchange rate measure the price competitiveness of one country compared to another, taking into account inflation in both countries and changes in the nominal exchange rate.

Answer 58

The Big Mac PPP example is effective in illustrating PPP as it simplifies the concept by using a universally available product (Big Mac) to demonstrate how exchange rates are determined to maintain purchasing power parity.

Question 59

Describe the impact of an increase in interest rates on the domestic currency according to UIP.

Answer 59

An increase in home interest rates leads to an appreciation of the domestic currency as it attracts foreign capital seeking higher returns, increasing demand for the domestic currency.

Question 60

Define UIP and explain its implications on exchange rates.

Answer 60

UIP (Uncovered Interest Parity) suggests that an increase in home interest rates should lead to an appreciation of the domestic currency, while an increase in foreign interest rates or an expectation of foreign currency appreciation should lead to a depreciation of the domestic currency.

Question 61

How does an increase in foreign interest rates or an expectation of foreign currency appreciation impact the domestic currency according to UIP?

Answer 61

It leads to a depreciation of the domestic currency as higher foreign interest rates attract capital away from the domestic currency, causing its value to decline.

Question 62

Describe the graphical representation of Uncovered Interest Parity (UIP).

Answer 62

It is a simple supply and demand diagram for the foreign exchange market, with the horizontal axis representing the quantity of the domestic currency and the vertical axis representing the exchange rate.

Question 63

Do an increase in home interest rates cause currency appreciation or depreciation in UIP?

Answer 63

An increase in home interest rates (or expectation of higher future rates) might shift the demand curve for the domestic currency to the right, causing the currency to appreciate.

Question 64

Define equilibrium exchange rate in the context of UIP.

Answer 64

It is the point where the demand for and supply of the domestic currency are equal, determining the prevailing exchange rate in the market.

Question 65

How do real-world factors influence the relationship between interest rates and exchange rates in UIP?

Answer 65

Factors such as risk, transaction costs, and capital mobility restrictions can influence the actual relationship between interest rates and exchange rates. Additionally, rational expectations and perfect information, assumed by UIP, may not always hold in practice.

Question 66

Describe the simplifying assumption of perfect competition in models of international trade.

Question 86

Describe the production possibility frontiers (PPF) in the context of classical trade theories.

Answer 86

The production possibility frontiers in classical trade theories can be linear (as in Smith and Ricardo's theories) or concave (as in HOS and neoclassical theories), representing different assumptions about the trade-offs between producing different goods.

Question 87

Does the neoclassical trade theory emphasise relative prices as a main factor for trade?

Answer 87

Yes, the neoclassical trade theory emphasises relative prices as the main factor influencing trade, distinguishing it from other classical trade theories.

Question 88

Describe the key concept of the Ricardian model in international trade theory.

Answer 88

The key concept of the Ricardian model is comparative advantage, where countries specialize in producing goods in which they have a lower opportunity cost compared to other countries.

Question 89

Define the Heckscher-Ohlin (H-O) theory and its main focus in international trade.

Answer 89

The Heckscher-Ohlin theory introduces the concept of factor endowments and focuses on how countries will export goods that intensively use their abundant factor of production and import goods that use the scarce factor.

Question 90

How does the Ricardian model demonstrate the potential for mutually beneficial trade between countries?

Answer 90

Even if one country is less efficient in producing both goods, the Ricardian model shows that there is still potential for mutually beneficial trade if the opportunity costs differ.

Question 91

Do the Heckscher-Ohlin (H-O) theory predict about factor prices over time as trade occurs?

Answer 91

The H-O model predicts that factor prices will equalize over time as trade occurs, leading to the convergence of wages and returns on capital between trading partners.

Question 92

Describe the factors that influence modern trade.

Answer 92

Various factors influence modern trade theories, including differences in technology, transportation costs, and non-economic considerations.

Question 93

Do classical trade theories incorporate additional elements to account for complexities? If so, what are they?

Answer 93

Yes, modern trade theories often incorporate additional elements to account for complexities beyond the original theories.

Question 94

Define gains from trade according to Smith, Ricardo, and HOS.

Answer 94

According to Smith and Ricardo, gains from trade are in terms of greater consumption possibilities and general efficacity of production. According to HOS, gains from trade are in terms of greater consumption possibilities and general efficiency of use of resources production.

Question 95

How do countries specialise in goods according to Ricardo and HOS?

Answer 95

According to Ricardo, countries specialize in goods where their comparative advantage is greater than the relations of prices. According to HOS, countries specialise in goods where the relations of factor intensities are greater than the relations of factor abundance.
