What will the multiplier be when the mps is 0, 0.4, 0.6, and 1? what will it be when the mpc is 1, 0.90, 0.67, 0.50, and 0? how much of a change in gdp will result if firms increase their level of investment by $8 billion and the mpc is 0.80? if the mpc instead is 0.67?

Multiplier = 1 / MPS

When MPS = 0 , Multiplier = 1 / 0 = Infinity

When MPS = 0.4 , Multiplier = 1 / 0.4 = 2.5

When MPS = 0.6 , Multiplier = 1 / 0.6 = 1.67

When MPS = 1 , Multiplier = 1 / 1 = 1

MPS = 1 - MPC

When MPC = 1, Multiplier = 1 / 1 - MPC = 1 / 1-1 = Infinity

When MPC = 0.90, Multiplier = 1 / 1 - MPC = 1 / 1-0.90 = 10

When MPC = 0.67, Multiplier = 1 / 1 - MPC = 1 / 1-0.67 = 3.03

When MPC = 0, Multiplier = 1 / 1 - MPC = 1 / 1 - 0 = 1

If MPC is 0.80, Multiplier = 1 / 1 - 0.80 = 5

change in GDP = 5 * $8 billion = $40 billion

If MPC is 0.67, Multiplier = 1 / 1 - 0.67 = 3.03

change in GDP = 3.03 * $8 billion = $24.24 billion

answer; /// the above statement is (true);

the correct answer is:

it required the president to inform congress within forty-eight hours of any new troop commitment.

the war powers resolution (1973) is a federal law designed to limit the u.s. president’s ability to initiate or intensify military actions abroad without the approval of the congress.

it establishes that the president can send armed forces into action abroad only by declaration of war by congress, statutory authorization, or in case of a national emergency created by attack upon the united states, its territories or possessions, or its armed forces.

it requires the president to notify congress within 48 hours of sending armed forces to military action.
