Document Summary

10. 1 the income-consumption and income-saving relationship: consumption and saving. The 45 degree line is a reference line. At each point on the 45 degree line consumption equals disposable income, c=di. If we let it measure disposable income, the vertical distance between it and the line labelled c represents the amount of savings (s) in that year. Saving is the amount by which actual consumption in any year falls short of the 45- degree line (s=di-c). Consumption and disposable income, 1992-2014: consumption schedule (c) The line c, which generalizes the relationship between consumption and disposable income, indicates a direct relationship and shows that households consume most of their income. This consumption schedule reflects the direct consumption-disposable income relationship. Households increase their spending as their disposable income rises and spend a large proportion of a smaller disposable income than a larger disposable income: saving schedule (s) In the example, the break even income is billion.

Specific assignment: Mark each statement either True or False. If a statement is false, explain (very briefly) why it is false.

Keynes hypothesized that consumption is positively related to income. True

The marginal propensity to consume, MPC, is measured as changes in consumption over changes in income. True

The MPC is merely the percent of oneâs income that is spent to purchase goods and services. True

The MPC is the slope of the consumption function.

If the MPC is .8, then it may be concluded that the MPS must be .2.

If a personâs income is $10,000 and that person is spending $7,500 on consumption, then it may be concluded that that person has a marginal propensity to save of .25.

The MPC and the MPS must sum to one, meaning that 1 â MPC = MPS

Given a linear (straight-line) consumption function, the MPC must be a constant.

At the point graphically at which the consumption function intersects the 45-degree reference line, the MPC must be equal to 1.

If the consumption function lies above the 45-degree reference line, then there must be negative saving in the economy.

Autonomous consumption is that level of consumption spending that is independent of the level of income.

A change in the level of income will shift the consumption function either upward or downward.

A change in the level of consumer wealth will shift the consumption function either upward or downward.

If the MPC has a positive value, then the MPS must have a negative value.

Saving is defined simply as disposable income minus consumption.

If the consumption function has a slope of 4/5, then the saving function must have a slope of .2.

Any factor that would shift the consumption function upward would shift the saving function upward also.

The average propensity to consume (APC), like the MPC, is simply the slope of the basic, Keynesian consumption function.

Given a typical shaped consumption function, as the level of income rises, the APC rises as well.

If a consumption function graphically starts at a point above the origin (i.e., has a positive vertical axis intercept), then the saving function must begin below the origin.

A dramatic rise in household inflationary expectations could be expected to shift the consumption function downward and the saving function upward.
