D) The MPC is greater than zero and less than one, and the APC falls as income rises. E) The APC is greater than zero and less than one, and the MPC falls as income rises. 42) The Smith family's disposable income rose from $40 000 per year to $42 000 and their desired consumption expenditure rose from $38 000 to $39 600.

E) marginal propensity to save is 0.8. 43) Jean Tremblay's disposable income rose from $40 000 per year to $42 000 and his desired consumption expenditure rose from $38 000 to $39 600. It can be concluded that his A) average propensity to consume decreased from 0.950 to 0.943. B) average propensity to save decreased from 0.950 to 0.943. C) marginal propensity to consume is 0.050. D) marginal propensity to consume increased from 0.050 to 0.058. E) marginal propensity to save is 0.80. 44) Bob Tetley's disposable income rose from $40 000 per year to $42 000 and his desired consumption expenditure rose from $38 000 to $39 500. It can be concluded that his A) average propensity to consume is constant. B) average propensity to save is always 0.25. C) marginal propensity to consume decreased. D) marginal propensity to consume is 0.25. E) marginal propensity to save is 0.25. 45) Which of the following statements must be true in the simple macro model ? A) APC increases as income rises. B) APS decreases as income rises. C) MPS and MPC are both negative. D) MPC is negative below a certain level of income. E) The sum of MPC and MPS is one. 46) If the Jones family's disposable income increases from $1200 to $1700 and their desired saving increases from -$100 to +$100, then the family's A) average propensity to consume is 0.60. B) average propensity to consume is 0.40. C) marginal propensity to consume is 0.40. D) marginal propensity to consume is 0.60. E) marginal propensity to save is 1. 47) Total desired saving divided by total income is called the A) average propensity to consume. B) average propensity to save. C) average propensity to spend. D) marginal propensity to save. E) total propensity to save. 48) The marginal propensity to save refers to the A) additional saving that occurs out of an additional dollar of income. B) additional saving that occurs out of an additional dollar of investment. C) total saving divided by a change in income. D) change in saving divided by total income. E) additional saving that occurs over time. 49) In a simple model of the economy, without government or taxes, a shock that causes an upward shift of the aggregate consumption function also causes ________ shift of the saving function. A) an equal upward B) a less-than-equal upward C) an equal downward D) a less-than-equal downward E) no 50) When desired consumption exceeds disposable income, desired saving is ________; when desired consumption is less than the disposable income, desired saving is ________.
