Table 7P - 1 shows the price of inputs and the price of outputs at each step in the production process of mak ing a shirt Assume that each of these steps takes place within the country . [LO 7.1 , 7.3 ] a. What is the total contribution of this shirt to GDP , using the standard expenditure method ? b . If we use a value -added method (i.e , summing the value added by producers at each step of the production process , equal to the value of output minus the price of inputs ) , what is the contribu tion of this shirt to GDP ? c If we mistakenly added the price of both inter mediate and final outputs without adjusting for value added , what would we find that this shirt contributes to GDP ? By how much does this overestimate the true contribution
Assume that an individual expects to work for 40 years andthen retire with a life expectancy of an additional 20 years.Suppose also that the individual’s earnings increase at a rateof 3 percent per year and that the interest rate is also 3 percent(the overall price level is constant in this problem). What(constant) fraction of income must the individual save ineach working year to be able to finance a level of retirementincome equal to 60 percent of earnings in the year just priorto retirement?

4. We sometimes need to find out how long it will take a sum of money (or something else, such as earnings, population, or prices) to grow to some specified amount. For example, if a company’s sales are growing at a rate of 20% how long will it take sales to double? (Hint: Assume that your current level of sales is at 100 units and find out how long it will take to get to 200 units if sales grow at 20% each year. Solve for N. Make sure you put the PV or FV as a negative number.)

If total expenditure is $675 billion, C=\$433 billion , I = $105 billion , and G=\$75 billion , what is NX ? How much are exports ? How much are imports?
3. Consider a world in which production of a good or service consists of a number of definitive tasks, which must all be performed correctly for the product to have positive value. Each task is filled by a single worker i whose skill level qirepresents the probability the worker performs her task correctly. Mathematically, if there are n tasks in the production of a good, and average production per worker with one unit of capital is 1 when all tasks are performed correctly, the production technology can be represented as: A) Give an example of an industry for which this might be a good model of production. What does this production function imply about the tradeoff between quality and quantity of labor in a given task? In this, how does it differ from a Cobb Douglas production function? B) Find the marginal product of increasing the skill of the ith worker. Suppose now there were two firms in the same industry that will bid for workers, and can pay them differentially according to…
Three students have each saved $1,000. Each has an investment opportunity in which he or she can invest up to $2,000. Here are the rates of return on the students’ investment projects: Student Return (Percent) Carlos 4 Felix 7 Janet 15 Assume borrowing and lending is prohibited, so each student uses only personal saving to finance his or her own investment project. Complete the following table with how much each student will have a year later when the project pays its return. Student Money a Year Later (Dollars) Carlos Felix Janet Now suppose their school opens up a market for loanable funds in which students can borrow and lend among themselves at an interest rate rr. A student would choose to be a lender in this market if his or her expected rate of return is than rr. Suppose the interest rate is 6 percent. Among these three students, the quantity of loanable funds supplied would be ,…

What was the average of these growth rates in Econoland over these 5 years? b. What term would economists use to describe what happened in year 3? (Click to select) Expansion Recession c. If the growth rate in year 3 had been a positive 2 percent rather than a negative 2 percent, what would have been the average growth rate?
A consumer's income in the current period is y = 100 and income in the future period is y'= 120. He or she pays lump-sum taxes t=20 in the current period and t'= 10 in the future period. The real interest rate is 0.1, or 10%, per period. (a) Determine what the consumer's optimal current-period and future-period consump tions are, and what optimal saving is, and show this in a diagram with the consumer's budget constraint and indifference curves. Is the consumer a lender or a borrower? (b) Now suppose that instead of y = 100 the consumer has y = 140 Again, determine optimal consumption in the current and future periods and optimal saving, and show this in a dia gram. Is the consumer a lender or a borrower? (c) Explain the differences in your results be tween parts (a) and (b).
