Vlad [161]

Answer:

If the marginal propensity to save is 0.12, the marginal propensity to consume(mpc) is 0.88, and the multiplier is 8.33.

Explanation:

From the question, we are given the following:

mps = Marginal propensity to save = 0.12

The marginal propensity to consume (mpc) and the multiplier can therefore be calculated as follows:

mpc = 1 - mps ........................ (1)

Substituting the values for mps into equation (1), we have:

mpc = 1 - 0.12

mpc = 0.88

Also, we have:

Multiplier = 1 / mps ..................... (2)

Substituting the values for mps into equation (2), we have:

Multiplier = 1 / 0.12

Multiplier = 8.33

Therefore, if the marginal propensity to save is 0.12, the marginal propensity to consume(mpc) is 0.88, and the multiplier is 8.33.

Assume that a country with an open economy has a fixed exchange-rate system and that its currency is currently overvalued in the
olasank [31]

Answer: b. The quantity of the country's currency supplied exceeds the quantity demanded.

Explanation:

A country operating a fixed-exchange rate system would be actively trading its currency to ensure that it remains at a certain rate. If the currency is overvalued, it means that the currency is actually weak and is being propped up by the company's actions in the forex market.

A reason for the weakness would be that the supply is higher than the demand of the currency which means that, as per the rules of supply and demand, the currency is trading at a lower price, i,e., it is weak.
