Figure 11.9 shows an investment function where the level of investment is, for the sake of concreteness, set at the specific level of 500. Specifically, we show that increased attention to the sound the food makes, or food sound salience, may serve as a consumption monitoring cue leading to reduced consumption. If the marginal propensity to consume = 0.75, then: A: the marginal propensity to save = 0.75.B: the marginal propensity to save = 1.33.C: the marginal propensity to save = 0.20.D: the marginal propensity to save = 0.25.E: since the marginal propensity to save and the marginal propensity to consume are unrelated, we cannot determine the marginal propensity to save from the information given.

The MPC and MPS are therefore: Since the Consumption Function and the Savings Function are both straight lines in this example, and since the slope of a straight line is constant between any two points on the line, it will be easy for you to verify that the MPC and the MPS are the same between any two points on the line. Decrease It was felt that by keeping the value of the pound high, it would help reduce inflationary pressures. It can be easily explained with the help of diagram that when there is no increase in money then LM curve is ,LM1 and when money supply increases then there is shift in LM curve from LM1 LM2.
