There are 100 households in the economy of Equalor. Initially, 99 of them have an income of \(\$ 10,000\) each, and one household has an income of $\$ 1,010,000$. a. What is the median income in this economy? What is the mean income? Through its poverty programs, the government of Equalor now redistributes income: it takes \(\$ 990,000\) away from the richest household and distributes it equally among the remaining 99 households. b. What is the median income in this economy now? What is the mean income? Has the median income changed? Has the mean income changed? Which indicator (mean or median household income) is a better indicator of the typical Equalorian household's income? Explain.

#tag_title# Initial Median and Mean Income Calculation #tag_content# Median Income \(= \frac{\$10,000 + \$10,000}{2} = \$10,000\) Mean Income \(= \frac{99(\$ 10,000) + (\$ 1,010,000)}{100} = \frac{\$ 990,000 + (\$ 1,010,000)}{100} = \frac{\$ 2,000,000}{100} = \$20,000\) The initial median household income is \(\$10,000\), and the initial mean household income is \(\$20,000\). #Part b# #tag_title# New Median Income #tag_content# After the government has redistributed income, each household will have an income of \(\$20,000\). Since all incomes are now the same, we can easily find the new median income: New Median Income = \$20,000 #tag_title# New Mean Income #tag_content# Since each household now has an income of \(\$20,000\), the new mean income does not change: New Mean Income = \$20,000 #Part c# #tag_title# Best Indicator for a Typical Equalorian Household's Income #tag_content# After the redistribution, both the median and mean income are the same at \(\$20,000\). This means that the typical Equalorian household's income is best represented by both the median and mean income, which is \(\$20,000\).

Step by step solution

01

Initial Median Income

To find the median income, we must first arrange the incomes in ascending order. Since there are 99 households with an income of \(10,000 each, and one household has an income of \)1,010,000: \$10,000, \$10,000, ..., \$10,000 (99 times), \$1,010,000 As the number of households (100) is an even number, the median income will be the average of the incomes of the 50th and 51st households.
02

Initial Mean Income

The mean income is calculated by adding up all the incomes and dividing by the number of households. Thus, Mean Income \(= \frac{99(\$ 10,000) + (\$ 1,010,000)}{100}\)

In the city of Notchingham, each worker is paid a wage rate of \(\$ 10\) per hour. Notchingham administers its own unemployment benefit, which is structured as follows: If you are unemployed (that is, if you do not work at all), you get unemployment benefits (a transfer from the government) of \(\$ 50\) per day. As soon as you work for only one hour, the unemployment benefit is completely withdrawn. That is, there is a notch in the benefit system. a. How much income does an unemployed person have per day? How much daily income does an individual who works four hours per day have? How many hours do you need to work to earn just the same as if you were unemployed? b. Will anyone ever accept a part-time job that requires working four hours per day, rather than being unemployed? c. Suppose that Notchingham now changes the way in which the unemployment benefit is withdrawn. For each additional dollar an individual earns, $\$ 0.50$ of the unemployment benefit is withdrawn. How much daily income does an individual who works four hours per day now have? Is there an incentive now to work four hours per day rather than being unemployed?

The accompanying table contains data on the U.S. economy for the years 1983 and \(2013 .\) The second column shows the poverty threshold. The third column shows the consumer price index (CPI), a measure of the overall level of prices. And the fourth column shows U.S. gross domestic product (GDP) per capita, a measure of the standard of living. $$ \begin{array}{c|c|c|c} \text { Year } & \begin{array}{c} \text { Poverty } \\\ \text { threshold } \end{array} & \text { CPI (1982-1984 = 100) } & \begin{array}{c} \text { GDP per } \\\ \text { capita } \end{array} \\\ 1983 & \$ 5,180 & 99.6 & \$ 15,525 \\\ 2013 & 11,490 & 233.0 & 53,086 \end{array} $$ a. By what factor has the poverty threshold increased from 1983 to 2013 ? That is, has it doubled, tripled, and so on? b. By what factor has the CPI (a measure of the overall price level) increased from 1983 to \(2013 ?\) That is, has it doubled, tripled, and so on? c. By what factor has GDP per capita (a measure of the standard of living) increased from 1983 to 2013 ? That is, has it doubled, tripled, and so on? d. What do your results tell you about how people officially classified as "poor" have done economically relative to other U.S. citizens?

The American National Election Studies conducts periodic research on the opinions of U.S. voters. The accompanying table shows the percentage of people, in selected years from 1952 to \(2008,\) who agreed with the statement "There are important differences in what the Republicans and Democrats stand for." $$ \begin{array}{|c|c|} \hline \text { Year } & \text { Agree with statement } \\\ 1952 & 50 \% \\\ 1972 & 46 \\\ 1992 & 60 \\\ 2004 & 76 \\\ 2008 & 78 \end{array} $$ What do these data say about the degree of partisanship in U.S. politics over time?

In a private insurance market, there are two different kinds of people: some who are more likely to require expensive medical treatment and some who are less likely to require medical treatment and who, if they do, require less expensive treatment. One health insurance policy is offered, tailored to the average person's health care needs: the premium is equal to the average person's medical expenses (plus the insurer's expenses and normal profit). a. Explain why such an insurance policy is unlikely to be feasible. In an effort to avoid the adverse selection death spiral, a private health insurer offers two health insurance policies: one that is intended for those who are more likely to require expensive treatment (and therefore charges a higher premium) and one that is intended for those who are less likely to require treatment (and therefore charges a lower premium). b. Could this system overcome the problem created by adverse selection? c. How does the British National Health Service (NHS) avoid these problems?

The accompanying table presents data from the U.S. Census Bureau on median and mean income of male workers for the years 1972 and \(2012 .\) The income figures are adjusted to eliminate the effect of inflation. a. By what percentage has median income changed over this period? By what percentage has mean income changed over this period? b. Between 1972 and \(2012,\) has the income distribution become less or more unequal? Explain.
