Income distribution. The government of a small country is planning sweeping changes in the tax structure in order to provide a more equitable distribution of income. The Lorenz curves for the current income distribution and for the projected income distribution after enactment of the tax changes are as follows:
Find the Gini index of income concentration for each Lorenz curve. Will the proposed changes provide a more equitable income distribution? Explain.

A state legislature is debating two proposals for eliminating the annual budget deficits after 10 years. The rate of decrease of the deficits for each proposal is shown in the figure. (a) What does the area between the two curves represent? (b) From the viewpoint of minimizing the cumulative state deficit, which is the better proposal? Explain

The Admission director for a college far from mart and town believes that an inverse relationship exists between a private college's average discount rate(determined by the average amount of scholarships students receive) and the annual yield (the percentage of admitted students who actually attend). The Director's independent variable is a private college's discount rate measured as a percentage, and the dependent variable is the college's annual yield measured as a percentage. The following results were obtained for a sample of 30 private colleges:
x- Discount rate(percentage) - range: 35 to 72 percent y- Annual Yield(percentage) - range: 12 o 81 percent

Keynesian consumption function expresses consumption as a function of disposable income.Specifically, it statesConst = B0 + B1 YDt + Ut,where: Const: aggregate personal consumer expenditures (PCE) in year t.YDt: Disposable income in year t.B1 is called the marginal propensity to consumer (MPC). Economists have found that the value ofMPC differs in the short run and the long run. Economists also found that in the long run the properform of the consumption function is:Const = B1 YDt + utUsing the “Consumption fn Data” file posted on part 2 of this question, estimate the consumption function in theU.S. You need to run two regressions:• Using 1960 to 1980 data (include all 1960 and 1980 data in the regression), estimate theshort run consumption function in the U.S.• Using all the data set, estimate the long run consumption function in the U.S.Part 1 of 2

- (2) The number of women in the workforce, based on data and projections from 1950 to 2050, can be modelled by a linear function. The number was 18.4 million in 1950 and is projected to be 81.6 million in 2030. Let x represent the number of years after 1950. (i). What is the slope of the line? (ii). What is the average rate of change in the number of women in the workforce during this time period? (iii). Use the slope from part (i) and the number of millions of women in the workforce in 1950 to write the equation of the line. please assist with question 2arrow_forwardU.S. Airplane Passenger Projections In a report issued by the U.S. Department of Transportation in 2012, it was predicted that the number of passengers boarding planes in the United States would grow steadily from the current 0.7 billion boardings/year to 1.2 billion boardings/year in 2032. Find a linear function f giving the projected boardings (in billions) in year t , where t =0 corresponds to 2012. What is the projected annual rate of growth of boardings between 2012 and 2032?

We use MME (Morphine Milligram Equivalents) as a measure of doses used. It went from 85.3 billion doses in 2000 to a level 164% higher in 2009. Assuming a linear trend (billion of doses as a function of years t), what is the vertical intercept of the linear function of the use of opioids, in billion? Assume that t=0 in 2003.

- In industry, the relationship between wages and the quit ratio of employees is defined to be the percentage of employees that quit within 1 year of employment. The quit ratio of a large restaurant chain that paid its employees the minimum hourly wage ($7.25 per hour) was .2 or 20 employees per 100. When the company raised the hourly wage to $8, the quit ratio dropped to .18, or 18 employees per 100. (a) Assuming a linear relationship between the quit ratio Q(x) and the hourly wage x, find an expression for Q(x). (b) What should the hourly wage be for the quit ratio to drop to 10 employees per 100?arrow_forwardThe median weekly earnings for 16-24-year-old men employed full time are given below.
