Consumption and Saving- End of Chapter Problem Which one of the following reasons makes it easier to forecast the impact of an income change on consumption for hand-to-mouth consumers than for consumption smoothers? It is easier because hand-to-mouth consumers only spend their permanent income. hand-to-mouth consumers save a large portion of their income. the marginal propensity to consume is 1 for consumption smoothers. hand-to-mouth consumers spend their entire income as they earn it.

True or False? Explain: The multiplier effect is likely to be greatest when the government spending is targeted at the poorest The poor will always spend most of the money they get as benefits as soon as possible Multiplier effect does not depend on who receives the money The richest people will spend a larger proportion of their money than the poorest
3. For the following problem, assume that the MPC, b, takes into account how much consumers spend as total income (Y) in the economy is changes. (Also: Hint GDP = Total Y) So we can rewrite our consumption function as : C= a +bY Assume: a= $2900 billion b=.75 GDP= $9,000 billion. A) What is C= B) What is S= C) If consumers were the only ones buying goods in the economy, would the economy have an excess supply of goods, excess demand of goods or would the economy be at equilibrium ?
1. Graphing the consumption function from the MPC Consider a hypothetical economy in which the marginal propensity to consume (MPC) is 0.50. That is, if disposable income increases by $1, consumption increases by 50¢. Suppose further that last year disposable income in the economy was $450 billion and consumption was $350 billion. On the following graph, use the blue line (circle symbol) to plot this economy's consumption function based on these data. CONSUMPTION (Billions of dollars) 700 600 500 400 300 200 100 0 -100 0 100 200 300 400 500 600 DISPOSABLE INCOME (Billions of dollars) 700 800 (?) From the preceding data, you know that the level of saving in the economy last year was $ economy is billion and the marginal propensity to save in this Suppose that this year, disposable income is projected to be $550 billion. Based on your analysis, you would expect consumption to be S billion and saving to be $ billion.
Using the table below to answer the following questions. Assume all values represent trillions of dollars. Construct a graph of the Aggregate planned expenditure What is the equilibrium expenditure? Explain what happens at a real GDP of $4 trillion dollars. (Note the aggregate expenditures and the effects on inventories) What are your total autonomous expenditures? What is the marginal propensity to consume? Ignoring imports and income taxes, what is the multiplier? If investment increases by $1.5 trillion, what is the change in real GDP?
answer quickly
What is individual Marginal Propensity to Consume and Marginal Propensity to Save? please provide an example for each.
Explain carefully how the multiplier works, defining the multiplier as part of your explanation. If the marginal propensity to save is smaller, explain carefully and fully how this affects the size of the multiplier.
Consider the graph below: Planned Aggregate Expenditure (PAE, billions of $) 1000 900 800 700 600 500 400 300 200 100 0 100 200 300 400 500 600 700 800 1 PAE 2 PAE Y PAE₁ 900 1000 Actual Aggregate Expenditure (Output or GDP, billions of $) a. What is the expenditure multiplier in this economy? b. What is the marginal propensity to consume in this economy?
Which best describes why the multiplier exists? When people spend money, that money ends up in the pockets or bank accounts of other people or organizations, who then use that money in some way. The multiplier exists because money spent today is always more valuable than money spent in the future, due to inflation and interest rates. When people see other people spending money, they know that the economy is about to improve, leading them to spend more money. When people see the government spending more money, they realize that the government thinks that prices are low; thus, they believe it is a good time to buy things.
What is the multiplier effect in economics? A. The tendency of consumers to save rather than spend B. The tendency of firms to reduce production during a recession C. The amplification of changes in spending through the economy D. The reduction of government spending to control inflation
