Students have asked these similar questions
look at the keynesian consumption function:c=c0+(mpc)(yd).which part of it relates to autonomous consumption?which part of it relates to included consumption?define autonomous consumption and induced consumption
In the simple Keynesian consumption function C = 84 +0.83*Y^d, what is the marginal propensity to consume (MPC) equal to?
Which of the following statements about the Keynesian framework are accurate?
a)Keynes posited a linear Consumption function C=Ca + mpcYd, where C is total desired consumption spending, Ca is consumption spending independent of income and Yd is disposable income and mpc is marginal propensity to consume
b) In the C=Ca +mpcYd the Ca is the vertical axis intercept parameter, and mpc is the slope parameter.
c) Keynes also posited that Investment spending was a function of expectations and the interest rate.
d) In the Keynesian investment function the firm's estimated profitability of potential investment projects were determined by expectations of future sales and costs.
e) Businesses would invest in those projects whose estimated profitability was greater than the market rate of interest.
f) If the firms don't have the cash, they will borrow funds and earn the difference between the rate of return on the project and the lower market rate of interest. If they have more cash than needed…
