1. Briefly define and explain Medicare.
1. Briefly define and explain [3 points each]MedicareIt is the government insurance for
elder that is 65+, and it covers the fee that is related to sickness (doctors’ office visits, the
drug costs, and etc.), which is financed by the payrool taxMedicaidIt is the government
insurance for the poor people, which also covers the drug fee and etc.Food Stamps (SNAP)It
is the stamps that the government issued for the poor people that they can only use the
stamps for the food.Total fertility rateIt is the number of babies that a woman gives birth to
assuming the current age-specific birth rate stay constant.2. The birth rate among
unmarried teenagers in the US rose from 22 per 1000 to 31 per 1000 from 1970 to 2010,
and the birth rate among all unmarried women in their childbearing years (15-45) rose
from 26 to 48 per 1000 during this period. Yet the teen birth rate, the birth rate for all
women 15-45 and the total fertility rate have all fallen sharply since 1970.a. How can both
the increases and the decreases be true? [10 points]b. What changes in behavior explain
these patterns?Explain how multiple programs designed to help the poor (Food
Stamps/SNAP, TANF, Earned Income Tax Credit, Housing Assistance) can result in very high
marginal tax rates on poor recipients of these benefits? [3 points]Means tested transfer
programs face conflicting goals of providing enough money for people with no other source
of income, not discouraging work, and minimizing total costs. Design 2 programs (benefit
for families with no other income, implicit tax rate, maximum income at which individuals
are no longer eligible) and explain how well they do in achieving the 3 goals. [5 points]You
estimate 2 regressions, where ln L is the natural log of the number of workers in millions
and ln W is the natural log of the hourly wage: [25 points]Labor demand ln L = 2.98 – 0,11
ln W R2 = 0.65(1.41) (0.03)Labor supply ln L = 2.63 + 0.10 ln W R2 = 0.58(1.28)
(0.04)Which coefficients are statistically significant and which are not?If the minimum wage
is $7.25, how many workers will firms want to hire, how many people will want to work,
and what is the unemployment rate in this labor market?If the minimum wage is $10.00,
how many workers will firms want to hire, how many people will want to work, and what is
the unemployment rate in this labor market?If the average worker in this labor market
works 30 hours per week and 50 weeks per year, what are the total earnings of all
minimum wage workers at $7.25 and $10.00? Give your answers in billions of
dollars.Compare the average annual earnings for all people in this labor market and the
unemployment rate when the minimum wage is $7.25 and $10. Given these numbers,
should the minimum wage be raised to $10?What percent of the change in annual earnings
from increasing the minimum wage did the CBO estimate would go to workers in poor

2. families?Draw a supply-demand diagram, labeling all relevant values of L and W.5. The
Earned Income Tax Credit gives workers 20% of their earnings for earnings up to $12,000
and begins to reduce the credit by 33% for every dollar of earnings above $16,000. For an
individual who earns $12 an hour and can work a maximum of 4000 hours in a yearDraw
the budget constraints before and after this EITC goes into effect. Label the number of hours
of work and money income for each kink in the budget constraint.Draw indifference curves
before and after the EITC goes into effectExplain the income and substitution effects of the
EITCState how hours of work and money income will change (more, less, no change)for 3
different people. A does not work at all before the EITC. B works 1200 hours. And C works
2000 hours. [15 points]6. A training program for high school dropouts has the following
costs and effects in years 12, 2, 3, and 4. After the 4th year, the effects go to zero (to keep the
calculations simple). All these costs and benefits occur at the end of years 12, 2, 3, or 4.
Assume that each crime costs $30,000 for jail costs and legal costs and inflicts $20,000 in
costs to the victim. The discount rate used by the government to evaluate training programs
is 10%. Calculate the present value of the program. [15 points]Year 1 2 3 4Cost per student

program in Q6 come from the following regression on a sample of participants in the
program and other high school dropouts from the same communities, age, sex, and
ethnicity, where P=1 for participants and P=0 for nonparticipants. [7 points]Crimes = 1.07 –
3.21P – .34 Ed – .05 Age + .28 Nonwhite R2 = .15(.52) (1.27) (.52) (.02) (.22)Which
coefficients are statistically significant?What is wrong with this equation?8. Suppose the
estimate of the effect of the program on participants comes from a regression of the
participants’ earnings in the year before the program (T-1), the year of the program (T1),
and the next 3 years (T2), (T3), and (T4). Earn = earnings in thousands of dollars. [8
points]Earn = 13 – 10 T1 + 18 T2 + 18 T3 + 16 T4 R2 = .27(6.1) (7.8) (8.2) (9.2) (10.3)Why
is there no variable for the year before the program?What is wrong with this
regression? “Looking for a Similar Assignment? Get Expert Help at an Amazing Discount!”
