Question 1

Suppose a Russian economist told you that since the fall of communism, the Russian income distribution has shifted to perfect inequality, you would know then (no need to calculate), that the Russian Gini coefficient is

Accepted Answer

The Gini coefficient measures income inequality within a population, ranging from 0 (perfect equality) to 1 (perfect inequality). Therefore, if the income distribution has shifted to perfect inequality, the Gini coefficient would be 1.

Question 2

Two South Pacific islands, Aba and Ema, have very different Gini coefficients. Aba's is 0.90 and Ema's is 0.40. That's enough information to tell you that

Accepted Answer

The Gini coefficient is a measure of income inequality within a population, ranging from 0 (perfect equality) to 1 (perfect inequality). A lower Gini coefficient indicates a more equal distribution of income. Therefore, Ema's lower Gini coefficient (0.40) compared to Aba's (0.90) means Ema has a more equal distribution of income.

Question 3

Over the last few decades, the U.S. Gini coefficient has

Accepted Answer

The U.S. Gini coefficient, a measure of income inequality, has increased moderately over the last few decades, indicating a widening gap between the wealthiest and poorest segments of the population.

Question 4

In the last 15 years, the U.S. Lorenz curve has

Accepted Answer

The Lorenz curve is a graphical representation of income or wealth distribution, with a perfectly equal distribution represented by a straight diagonal line. A movement further from the diagonal, as indicated by choice D, signifies an increase in inequality, which has been the trend in the U.S. over the last 15 years.

Question 5

The Gini coefficient is 0.27 for Japan and 0.45 for the U.S. This means that Japan

Accepted Answer

The Gini coefficient is a measure of income inequality within a population, ranging from 0 (perfect equality) to 1 (perfect inequality). A lower Gini coefficient indicates a more equal distribution of income. Therefore, Japan's lower Gini coefficient (0.27) compared to the U.S. (0.45) means that Japan has a more equal distribution of income than the U.S.

Question 6

Economists attribute the high Gini coefficients among less-developed countries primarily to their

Accepted Answer

Less-developed countries often have predominantly agricultural economies, which can lead to high income inequality and thus higher Gini coefficients due to the concentration of land and resources in the hands of a few.

Question 7

The value of the accumulated assets of an individual is called

Accepted Answer

Wealth refers to the total value of all accumulated assets owned by an individual, including money, real estate, and personal property, minus any debts.

Question 8

Examples of life-cycle wealth include all of the following except

Accepted Answer

Life-cycle wealth includes assets that individuals accumulate over their lifetime, such as homes (A), stocks and bonds (B), automobiles (D), and personal clothing (E). Wages and salaries (C) are considered income, not accumulated wealth.

Question 9

In colonial days, the wealth holdings among the colonists were

Accepted Answer

Wealth holdings in colonial days, as in most historical and modern contexts, were unequally distributed among the population. This inequality stemmed from various factors, including land ownership, inheritance laws, and economic opportunities, which varied significantly among colonists.

Question 10

The case for income inequality is supported by which of the following arguments?

Accepted Answer

Economic efficiency is often cited as an argument for income inequality, suggesting that it incentivizes productivity and innovation, leading to overall economic growth.

Question 11

Which philosopher believes that advocates of a position on income distribution must look at a society in the making, where no one yet knows what rules govern economic activity and income distribution?

Accepted Answer

John Rawls, in his theory of justice, argues that principles of justice are those that would be chosen by individuals in an original position of equality, behind a "veil of ignorance," where they do not know their place in society, their class position or social status, nor their fortune in the distribution of natural assets and abilities. This thought experiment is designed to ensure fairness and impartiality in the principles chosen for the basic structure of society, including the rules governing economic activity and income distribution.

Question 12

A case for income equality includes all the following except

Accepted Answer

Maximum economic growth is not necessarily a direct case for income equality; rather, it can sometimes be argued that inequality might incentivize growth.

Question 13

A.P. Lerner believes that society maximizes its total utility when income distribution is

Accepted Answer

Lerner believed that if individual utility functions are the same, then society maximizes its total utility when income distribution is perfectly equal. This is because, under the assumption of identical utility functions, each individual values an additional unit of income equally, making equal distribution the most efficient in terms of total utility maximization.

Question 14

Suppose the marginal utility of a dollar for Carl is 7 utils and for Judy, 12 utils. According to Lerner, society will maximize its total utility if

Accepted Answer

According to Lerner's theory of welfare economics, transferring resources from an individual with a lower marginal utility of money to one with a higher marginal utility of money increases total societal utility. Since Carl's marginal utility of a dollar is lower than Judy's, transferring money from Carl to Judy will increase total utility.

Question 15

According to Lerner, if we do not know people's utility functions, we

Accepted Answer

Lerner suggests that without knowledge of people's utility functions, assuming they are equal makes less of a mistake compared to other assumptions, as it avoids the biases and inaccuracies inherent in assuming specific differences in utility functions among different income groups.

Question 16

According to advocates of income inequality, if income were to be distributed equally,

Accepted Answer

The answer of According to advocates of income inequality, if...

Question 17

What economic policy would increase the Gini coefficient?

Accepted Answer

Lowering the minimum wage would likely increase income inequality by reducing earnings for low-wage workers, thus increasing the Gini coefficient, which measures income inequality.

Question 18

Advocates of income inequality argue that government policy designed to lower the Gini coefficient significantly would likely cause, in the long run,

Accepted Answer

Advocates of income inequality often argue that redistributive policies can reduce incentives for productivity and investment, potentially leading to a decline in overall economic growth and, consequently, the income of the poor.

Question 19

The two standard ways of defining poverty thresholds are

Accepted Answer

The two standard ways of defining poverty thresholds are "percentage of median income" and "basic needs." The first method considers individuals poor if their income is significantly below the median income of the population, often set at 50% or 60%. The "basic needs" approach calculates poverty based on whether individuals can afford essential goods and services, such as food, shelter, and healthcare.

Question 20

If the poverty threshold is set at 60 percent of median income, and if median income were $20,000, then people in poverty earn less than

Accepted Answer

The poverty threshold is calculated as 60% of the median income. If the median income is $20,000, then 60% of $20,000 is $12,000. Therefore, people earning less than $12,000 would be considered in poverty.

Quiz 18: Income Distribution and Poverty

Suppose a Russian economist told you that since the fall of communism, the Russian income distribution has shifted to perfect inequality, you would know then (no need to calculate) , that the Russian Gini coefficient is
