Complete the following table to help you determine the poverty rate in Perkopia in 2007. To do this, begin by determining the total income of all individuals in each quintile using the fact that total annual income in the economy is $500,000,000. Next, determine the income of an individual in each quintile by dividing the total income of that quintile by the number of people in that quintile. (Hint: Recall that Perkopia has a population of 10,000 people.) Finally, determine whether the individual income for each quintile falls below the poverty line of $27,400.

Lowest	3.8			(Yes/No)
Second	9.9			(Yes/No)
Middle	15.2			(Yes/No)

Using the information in this table, the poverty rate in Perkopia in 2007 is(10%/20%/40%/50%/60%).

Suppose that the government introduces a welfare program in which any individual with an income of less than $27,400 per year receives a lump-sum transfer payment of $10,000 from the government. Assume that, in the short run, there is no change in labor-supply behavior among the people in Perkopia.

In the year 2007, the poverty rate after the introduction of the welfare program in Perkopia is (10%/20%/40%/50%/60%).

Again, suppose the government introduces a welfare program in which any individual with an income of less than $27,400 receives a lump-sum transfer payment of $10,000 from the government. Lorenzo, a resident of Perkopia who currently earns an income of $26,942, has the opportunity to work overtime and earn an additional $1,100 this year.

Which of the following statements are correct? Check all that apply.

Lorenzo may accept the overtime if he feels that taking it will increase the chances of his receiving a significant promotion.

The $10,000 in aid presents a disincentive for Lorenzo to make more than $27,400 per year.

Lorenzo would gain more income by turning down the overtime than he would if he accepted the overtime.
