1A.Using the Keynesian-cross model, explain what happens to
output following a decrease in the interest rate?
1B. Using the IS-LM model, show and explain how a decrease in
taxes affects the interest rate and output.
1a. Derive government spending and tax multiplier in the
Keynesian-cross model using calculus
1b. Consider the model of Keynesian cross with fixed planned
investment expenditure, government spending and taxes. Assume that
consumption function is given by C=a+mpc*(Y-T), where the parameter
a >0 is called autonomous consumption, and the marginal
propensity to consume satisfies 0< mpc <1. Compute
equilibrium output (income) as a function of parameters (a and mpc)
and exogenous variables. How does equilibrium output depend on a?
mpc? Government...

What happens to interest rate, output, prices and wages; as
government expenditures decrease within a general equilibrium
framework?
Could you please draw related graphs to explain?
Thank you!
In
the Keynesian model, a decrease in government purchases affects
output by
1. decreasing labor supply, because workers feel effectively
poorer.
2. decreasing saving to pay for future taxes, lowering the
real interest rate and shifting the IS curve to the left.
3. decreasing the real interest rate due to crowding out,
reducing aggregate demand.
4.decreasing aggregate demand as national saving
declines.
In the expenditure–output or Keynesian cross model, the
equilibrium occurs where the aggregate expenditure line (AE line)
crosses the 45° line. Given algebraic equations for two lines, the
point where they cross can be calculated easily. Imagine an economy
with the following characteristics.
Y = Real GDP or national income
C = Consumption = 50 + 0.8Y
I = Investment = 200
G = Government spending = 100
Calculate the equilibrium level of income (Y)
Suppose G increases to 125...
For each of the following changes, what happens to the real
interest rate and output in the very short run, before the price
level has adjusted to restore general equilibrium? (a) Wealth
rises. (b) Money supply rises. (c) The future marginal productivity
of capital increases. (d) Expected inflation declines. (e) Future
income declines.
What happens in the Keynesian model if households decide to be
thriftier that is spend less and save more? Do the following
multistep exercise to find out.
