suppose that a certain country has an MPC of 0.9 and a real GDP of $400 billion. if its investment spending decreases by $4 billion, What is the specific Savings function in this problem is Autonomous Consumption is $1,000?

Expert Solution

Consumption function

C=a+bY

a is autonomous consumption

b is slope

Y is income

Saving function

S= -a+sYd

As it can be seen in the consumption and saving function, a is autonomous consumption and –a is autonomous saving.

Since value of a is given $1,000.

When MPC=0.90

MPS=1-MPC

=1-0.9

=0.1

Real GDP (Y)=$400 billion

Saving function

S=-1000+0.1Y

Suppose a country's MPC is 0.8, and in this country, government seeks to boost real GDP by either increasing government purchases by $50 billion or by reducing taxes by the same amount. Instructions: Round your answers to one decimal place when appropriate. If you are entering any negative numbers be sure to include a negative sign (-) in front of those numbers. a. If it increases government purchases, real GDP will increase by $ ____billion, suggesting an expenditures multiplier of...

Suppose that real GDP is currently $15 trillion and the MPC is .8. How much would government have to increase spending to increase real GDP by $5 trillion? If the MPC is .7 and government decreased spending by $500 billion, what is the spending multiplier and by how much would real GDP decrease?

Suppose country A has a GDP of $10 billion and country B has a GDP of $2 billion. If we assume that there are only two countries A and B in the world and that the coefficient of B can be approximated by the inverse of the world GDP, approximately what volume of trade is predicted to occur between the two countries if they are both 500 miles apart and our uncertainty parameter is given by 1.5. Suppose instead that...

1) If the Federal Reserve wants to up GDP by $400 billion and the MPC=.95, by how much would they need to change government spending? Would G be increasing or would it be decreasing? 2) If instead of using government spending changes, they instead change taxes: by how much would they to change? WOuld they be increasing or would they be decreasing?

If the MPC is .9, and government purchases increase by $6,000, real GDP demanded will:
