Questions and Answers

What are the two primary sides used to measure Gross Domestic Product (GDP)?

The income side and the production side.

What is a key difference between GDP per capita level and GDP per capita growth?

GDP per capita level refers to the total income/production per person at a specific point in time, while GDP per capita growth refers to the change in that amount over time.

According to the provided text, what are three limitations of GDP as a measure of progress?

GDP does not measure activity outside of the market, health developments, or environmental destruction.

What is the core prediction of the Malthusian theory regarding population and resource growth?

That population tends to increase faster than the supply of subsistence goods, leading to poverty. Signup and view all the answers

In the Solow-Swan growth model, what two factors determine the level of output per worker ($Y/L$)?

How does the concept of 'purchasing power parity' (PPP) adjust GDP when making international comparisons?

PPP adjusts GDP by accounting for the differences in the cost of goods and services across different countries, often using 'international dollars' to allow a more realistic comparison of living standards and economic output. Signup and view all the answers

What is meant by diminishing returns to capital in the context of the Solow-Swan model, and why does this limit economic growth?

Diminishing returns to capital means that as the amount of capital per worker increases, the additional output per additional unit of capital will eventually decrease. This limits growth because while additional capital can boost productivity, there is an upper limit to this effect. Signup and view all the answers

How does Smithian growth differ from Malthusian growth in its view of economic progress?

Smithian growth emphasizes the division of labor and market expansion as drivers of progress, leading to sustained growth, whereas Malthusian growth predicts that any gains will be offset by population growth, resulting in no sustained long-term increase in living standards.

Besides environmental damage and health, what are two other key areas that the standard GDP measurement often neglects to account for?

Besides environmental damage and health, GDP often neglects activity outside the 'market', such as unpaid work, and elements of human well-being like happiness or political freedom. Signup and view all the answers

In the context of economic growth, what is the significance of 'Total Factor Productivity' (TFP) as it relates to the Solow residual?

TFP represents the portion of output growth not explained by increases in capital or labor. The Solow residual thus captures the improvements in technology, efficiency or other aspects that boost production without higher inputs. Signup and view all the answers

Explain why, under Malthusian theory, increased income would simply lead to an increase in poverty.

According to Malthusian theory, any rise in income will be consumed by a rising population, thus restoring equilibrium at the subsistence level. Therefore any temporary increase in wealth will be nullified by population growth and will not lead to long-lasting improvements. Signup and view all the answers

How does the concept of division of labor, as described in Smithian growth, lead to increased economic output?

Division of labor increases economic output by allowing workers to specialize in specific tasks, leading to greater efficiency, skill development, and productivity. This is in contrast to an individual producing all required goods and services themselves. Signup and view all the answers

What are two alternative measures of progress, mentioned in the text, that can be used to supplement or replace GDP?

Two alternative measures of progress mentioned are the Human Development Index (HDI) and the Better Life Index. These both include additional measures, beyond economic output, in their assessment of a nation's performance. Signup and view all the answers

Flashcards

Gross Domestic Product (GDP)

A measure of the total value of goods and services produced within a country over a specific period. It can be calculated from the income earned, the total production, or the total expenditure within the country.

GDP per capita

The GDP divided by the population, indicating the amount of income or production per person in a country.

Constant Price GDP growth

The growth of GDP measured in constant prices, adjusted to account for inflation, providing a true measure of economic growth.

Purchasing Power Parity (PPP)

An adjustment used to compare GDP across countries, considering differences in purchasing power of currencies.
