n the year of 2019, the U.S. economy produced a total output of $20.75 trillion. During the same year, the U.S. federal government spent $7.88 trillion. The desired consumption and desired investment in the U.S. for the year is described by: Cd=15-150r, Id=10-200r Where Cd is the desired consumption in trillions of $, Id is the desired investment in trillions of $, and r is the real interest rate in decimal form. if the average real interest rate during the year 2019, is 4.1%, how much is the desired national saving, Sd, in trillions of $? round answer to at least 2 decimal places.

Is a family a household? Is a household a family? Which sector (Households, Businesses, or International) spends the most? Which sector spends the least? Which sector, because of its volatility, has an importance greater than is warranted by its size? What does it mean if net exports are negative? People sometimes argue that imports should be limited by government policy. Suppose a government quota on the quantity of sugar to be imported to the United States occurs. What is likely to happen to the price of sugar in the United States and in the rest of the world? List the four sectors of the economy along with the type of spending associated with each sector. Order the types of spending in terms of magnitude, and give an example of each kind of spending. Using the interconnection between sectors of the economy, explain the effects of imposing an increase in taxes on the household sector.

Suppose you know the following facts about consumer behavior of Amy in 2019. In a year, Amy spends $10000 on basic household items regardless of how much she is earning. For every dollar of disposable income earned, Amy spends 50% on extra purchases. Amy pays taxes in the amount of $1000, and receives no transfers. Use this information to:  Derive Amy’s consumption function in nominal terms. Suppose the price level index in the economy for 2019 is estimated to be P = 2. Rewrite the consumption function in real terms.
