- Use a diagram to explain the three main characteristics of the consumptionfunction.arrow_forwardUsing the figure below, graphically prove that the consumer saves less when his future income increases.arrow_forwardIf consumers decide to increase saving, then C decreases, r decreases, I increases, and Y:arrow_forward
- Draw the consumption function as the relation of the consumer's income and expenditure. What does the slope of the consumption function depend on? Is the consumer's income the only factor determining the level of his consumption spending?arrow_forwardSuppose the household wants to consume equal amounts in two periods. She earns $100 in the first period and $150 in the second period. The interest rate depends on whether she saves or borrows. The interest rate on saving is 1%, while the interest rate on borrowing is 10%. What is her optimal consumption? Be sure to explain why you choose to save or borrow.arrow_forwardFor each of the following events, consider how you might react. What things might you consume more or less of? Would you work more or less? Would you increase or decrease your saving? Are your responses consistent with the discussion of household behavior in this chapter? a. You have a very close friend who lives in another city, a 3-hour bus ride away. The price of a round-trip ticket rises from $20 to $45. b. Tuition at your college is cut 25 percent. c. You receive an award that pays you $300 per month for the next 5 years. d. Interest rates rise dramatically, and savings accounts are now paying 10% interest annually. e. The price of food doubles. (If you are on a meal plan, assume that your board charges double.) f. A new business opens up nearby offering part-time jobs at $20 per hour.arrow_forward
- Refer to Figure 26-1. What is measured along the vertical axis of the graph? a. The tax rate b. The interest rate c. The quantity of investment d. The quantity of savingarrow_forwardCreate a speech about the relationship of income, saving and consumption to price changes in shopping.arrow_forwardThe following table shows the quantity D of wheat, in billions of bushels, that wheat consumers are willing to purchase in a year at a price P, in dollars per bushel. D = quantity of wheat P = price 1.0 $2.05 1.5 $1.75 2.0 $1.45 2.5 $1.15 In economics, it is customary to plot D on the horizontal axis and P on the vertical axis, so we will think of D as a variable and of P as a function of D. (a) Show that these data can be modeled by a linear function. For each increase of 0.50 in D there is of in P. Find its formula. (Use P for price and D for quantity.)P = −.6d+265 (b) Add the graph of the linear formula you found in part (a), which is called the market demand curve, to the following graph based on the following table for market supply curve. S = quantity of wheat P = price 1.0 $1.35 1.5 $2.40 2.0 $3.45 2.5 $4.50arrow_forward
- Suppose that the least amount of goods and services that Roberto will consume in a year is $40,000. Roberto tends to save $0.30 of every dollar of disposable income that he makes. Use the given line to graph Roberto's consumption function for disposable income levels between $0 and $200,000. Move each endpoint to the appropriate spot on the graph.arrow_forwardSuppose that the least amount of goods and services that Roberto will consume in a year is $40,000.Roberto tends to save $0.30 of every dollar of disposable income that he makes. Use the given line to graph Roberto's consumption function for disposable income levels between $0 and $200,000. Move each endpoint to the appropriate spot on the graph.arrow_forwardDraw a diagram to describe this: Marginal consumption Cm decreases -> The amount of money consumed C also decreases => Household saving S (Saving) increases because S = Yd - C -> The supply of loanable funds increases (due to an increase in household savings) -> the lending interest rate decreases (in the condition that the demand for loan funds remains constant)arrow_forward
