Suppose economists observe that an increase in government spending of $14 billion raises the total demand for goods and services by $42 billion.
If these economists ignore the possibility of crowding out, they would estimate the marginal propensity to consume (MPC) to be .
Now suppose the economists allow for crowding out.
Their new estimate of the MPC would be than their initial one.
3. a) Suppose economists observe that an increase in government spending of 300 crore taka raises the total demand for goods and services to 400 crore taka. If these economists ignore the possibility of crowding out effect, calculate the marginal propensity to consume (MPC)?
b) Now suppose economists allow for crowding out. Would their new estimate of the MPC be smaller or larger than your answer to part a, explain.
What is the eventual effect on real GDP if the government increases its purchases of goods and services by $75,000? Assume the marginal propensity to consume (MPC) is 0.75.

What is the eventual effect on real GDP if the government, instead of changing its spending, increases transfers by $75,000? Assume the MPC has not changed.
$
An increase in government transfers or taxes, as opposed to an increase in government purchases of goods and services, will result in
an identical eventual effect on real GDP.
no change to real GDP.
a larger eventual effect on real GDP.
a smaller eventual effect on real GDP.

Assume the marginal propensity to consume (MPC) is 0.75. What is the eventual effect on real GDP if the government, instead of changing its spending, increases transfers by $60,000? Assume the MPC has not changed. An increase in government transfers or taxes, as opposed to an increase in government purchases of goods and services, will result in O no change to real GDP. O a smaller eventual effect on real GDP. a larger eventual effect on real GDP. O an identical eventual effect on real GDP.arrow_forwardA country is in the midst of a recession with a real GDP estimated to be $1.8 million below potential GDP. The governement's policy analyss believe the current value of the marginal propensity to consume (MPC) is 0.90. (Please answer all parts) a. If the government wants real GDP to equal potential GDP, by how much should it increase governement spending? Alternatively, by how much should it reduce taxes? b. Suppose that during the recession people have become less confident and decide they will spend only 50% of any additional income. In this case, if the governement increases spending by the amount calculated in part A, will real GDP end up less than , greater than or equal to potential GDP? by how much? c. With the same decrese in consumer spending as described in part B, if the governement decreases taxes by the amount calculated in part A, will real GDP end up less than, greater than or equal topotential GDP? by how much? d.

- Suppose the following list of events describes all of the economic activity resulting from an increase in government spending. Suppose that at each step after the initial one, the marginal propensity to consume is 0.62 and the tax rate is 8%. Step 0. The government spends $8500 on meat to host a very large dinner for foreign diplomats. Step A. The butcher takes the income earned by selling the meat, saves some, and spends the rest on a wedding cake for his daughter. Step B. The baker who produced the wedding cake saves some of her earnings and uses the rest to purchase beautiful candlesticks as gifts for all of her friends. Step C. The local candlestick maker saves some of his revenue for retirement and spends the rest on building materials to improve his house.
