1. According to the Bureau of Economic Analysis, during therecession of 2007–2009, household saving as a fraction of dis-posable personal income increased from a low of just over1 percent in the first quarter of 2008 to 5 percent in the secondquarter of 2009. All else equal, what impact would this changein saving have on the MPC, MPS, and multiplier? How wouldthis change affect equilibrium output when planned invest-ment changes? 2. Assume in a simple economy that the level of saving is –500 whenaggregate output equals zero and that the marginal propensity tosave is 0.2. Derive the saving function and the consumption func-tion, and draw a graph showing these functions. At what level ofaggregate output does the consumption curve cross the 45° line?Explain your answer and show this on the graph.

DI Consumption Saving АРС APS MPC MPS 8. 40 40 80 72 120 104 160 136 200 168 240 200 (a) Refer to the above data. If plotted on a graph, the slope of the consumption schedule would be: (b) The break-even level of income is ($ ) where saving equals ( $ :). Households dissave ( $ ). Dissaving occurs at the lowest levels of income as households spend ( more, less ) than they receive in disposable income. This dissaving could occur with households liquidating (selling for cash) their assets or borrowing money. As income rises we see that savings ( increases, decreases ) by a greater and greater amount. (c) If consumption increases by $10 billion at each level of disposable income, the average propensity to consume (APC) will ( change, unchange) and/but the marginal propensity to consume (MPC)will ( change, not change).
