Facts and Measurement of Economic Growth Practice Quiz (11 questions)

Question 1

1. Which 2022 measure of world economic output was higher?

World nominal GDP, at $101.33 trillion

World GDP per capita at purchasing power parity, at $17,523

World GDP per capita at market prices, at $12,743.9

World GDP measured at purchasing power parity, at $139.32 trillion

Explanation

Purchasing-power-parity GDP was $139.32 trillion in 2022, compared with nominal GDP of $101.33 trillion. GDP per capita figures are averages per person rather than totals for the world economy.

Answer

World GDP measured at purchasing power parity, at $139.32 trillion

Question 2

2. Which statement correctly distinguishes the international poverty line from world GDP per capita in 2022?

Both measures represented daily income thresholds applied to individual households.

Both measures represented average annual output divided across the world population.

The poverty line was an annual output average, while GDP per capita was a daily income threshold.

The poverty line was a daily income threshold, while GDP per capita was an annual average output measure.

Explanation

The international poverty line was set at $2.15 per day, whereas GDP per capita described average annual output per person. Treating both figures as the same type of measure confuses a poverty threshold with an economic average.

Answer

The poverty line was a daily income threshold, while GDP per capita was an annual average output measure.

Question 3

3. Which sequence best describes the long-term growth of the world population?

From nearly 250 million at the beginning of agriculture to 5.3 billion in 2023

From 728 million at the beginning of agriculture to 6.8 billion in 1990

From 5.3 billion at the beginning of agriculture to 8.1 billion around 2,000 years ago

From less than 5 million at the beginning of agriculture to 8.1 billion in 2023

Explanation

World population rose from fewer than 5 million when agriculture began about 12,000 years ago to 8.1 billion in 2023. The other sequences assign the historical population figures to incorrect periods.

Answer

From less than 5 million at the beginning of agriculture to 8.1 billion in 2023

Question 4

4. A country becomes more urban as its cities gain residents faster than the country’s total population; what process does this illustrate?

Urbanization, which increases the urban share of the population

Population decline, which reduces the number of city residents

Ruralization, which increases the rural share of the population

Environmental dependence, which shifts workers toward natural resources

Explanation

Urbanization occurs when the urban population grows faster than the total population, increasing the urban share and contributing to a predominantly urban world. Ruralization describes a shift toward rural settlement, while the other choices concern different demographic or economic processes.

Answer

Urbanization, which increases the urban share of the population

Question 5

5. What does the term 'global mobility' primarily refer to in the context of income differences?

The international flow of goods and services driven by trade agreements.

The transfer of financial assets across borders to optimize returns.

The movement of people between countries seeking better economic opportunities.

The migration of skilled workers from developed to developing nations.

Explanation

Global mobility in income differences mainly involves people moving across countries in search of higher income opportunities. The other options relate to financial or goods movement, not directly to income mobility.

Answer

The movement of people between countries seeking better economic opportunities.

Question 6

6. Who is the economist associated with identifying the six long-run regularities of economic growth, known as Kaldor facts?

Milton Friedman

Nicholas Kaldor

Adam Smith

John Maynard Keynes

Explanation

Nicholas Kaldor is the economist who identified the six long-run regularities of economic growth, known as Kaldor facts. The other economists are notable but did not formulate these specific regularities.

Answer

Nicholas Kaldor

Question 7

7. What is the primary purpose of calculating nominal GDP in an economy?

To assess the inflation-adjusted value of output over time

To compare the purchasing power of different currencies

To measure the total market value of all final goods and services at current prices

To determine the average income per person in the economy

Explanation

Nominal GDP is used to measure the total market value of all final goods and services produced in an economy during a specific period at current prices. It does not account for inflation, which is the purpose of real GDP.

Answer

To measure the total market value of all final goods and services at current prices

Question 8

8. When was the concept of Purchasing Power Parity (PPP) formally established as a key economic theory?

In the 1960s, with the development of modern macroeconomics

During the Bretton Woods Conference in 1944

The early 20th century, around 1910

After the collapse of the Bretton Woods system in 1971

Explanation

Purchasing Power Parity was developed as a theory in the 1960s to compare the purchasing power of different countries' currencies. The concept gained prominence with the work of economists like Gustav Cassel.

Answer

In the 1960s, with the development of modern macroeconomics

Question 9

9. How does the concept of Purchasing Power Parity (PPP) differ from nominal exchange rates in comparing international living standards?

PPP is only applicable to tradable goods, whereas nominal exchange rates apply to all goods and services.

PPP is based on market exchange rates, whereas nominal rates are adjusted for inflation to compare purchasing power.

PPP uses international prices to compare goods and services across countries, while nominal exchange rates reflect market currency values.

PPP measures the actual cost of living in each country, while nominal exchange rates only compare currency values without considering prices.

Explanation

PPP compares the relative prices of a basket of goods across countries using a common set of prices, unlike nominal exchange rates which are determined by currency markets. This makes PPP more suitable for comparing living standards.

Answer

PPP uses international prices to compare goods and services across countries, while nominal exchange rates reflect market currency values.

Question 10

10. Who is credited with proposing the six long-run regularities, known as Kaldor facts, that describe persistent patterns in economic growth?

John Maynard Keynes

Nicholas Kaldor

Adam Smith

Milton Friedman

Explanation

Nicholas Kaldor is credited with identifying the six long-run regularities, or Kaldor facts, that describe consistent patterns observed in long-term economic growth. The other economists are known for different contributions to economic theory.

Answer

Nicholas Kaldor

Question 11

11. What is a primary cause of the consistent long-term growth in output per worker as identified by Kaldor's regularities?

Fluctuations in short-term business cycles

Technological progress increasing productivity over time

Decreases in capital per worker due to depreciation

Increases in the labor force without changes in capital

Explanation

Technological progress is a key driver of sustained growth in output per worker, as identified by Kaldor's regularities. Fluctuations in business cycles are short-term effects and do not cause long-term growth.

Answer

Technological progress increasing productivity over time
