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

Suppose that consumer spending initially rises by $5 billion for every 1 percent rise in household wealth and that investment spending initially rises by $20 billion for every 1 percentage point fall in the real interest rate. Also assume that the economy�s multiplier is 3. If household wealth falls by 6 percent because of declining house values, and the real interest rate falls by 2 percentage points, in what direction and by how much will the aggregate demand curve initially shift at each price level? The aggregate demand curve will shift_____ by $____ billion. In what direction and by how much will it eventually shift? The aggregate demand curve will shift_____ by $____ billion..

A) aggregate demand curve B) savings line C) 45-degree line D) consumption function 2) Which of the following is a reason why increases in the price level result in a decline in aggregate expenditure? A) Price level increases raise real wealth, which causes consumption spending and aggregate expenditure to decline. B) Price level increases cause firms and consumers to hold more money, which raises the interest rate. Higher interest rates lower consumption and planned investment expenditures, which lowers aggregate expenditure.
