Students have asked these similar questions
assume you are given a $100 raise, and
decide to save $20 of that money. also
assume that if you make zero income in a
year, you will still spend $7000.
a.) what is your consumption function?
b.) if you earn $20000 in a year how much will
you spend?
c.) will you be able to save while earning the
above income?
Suppose that c= a+by, where c= consumption, a = consumption at zero income, b = the slope of the
consumption from function, and y = income,
a) are c and y positively related or are they negatively related?
b) If graphed, would the curve of this equation slope upward or downward?
c) What is the value of c if a = 10, b = 50 and y = 200?
d) what is the value of y if c = 100, a = 10 and b = 25?

Government spending and taxes are constant. Suppose that consumers decide to
consume less (and therefore to save more) for any given amount of disposable income.
Specifically assume that consumer confidence () falls. What will happen to output?
As a result of the effect on output you determined in part (a), what will happen to
investment? What will happen to public saving? What will happen to private saving?
Explain. What is the effect on consumption?
Suppose that consumers had decided to increase consumption expenditure, so that
Co had increased. What would have been the effect on output, investment, and private
saving in this case? Explain. What would have been the effect on consumption?
Comment on the following logic: "when output is too low, what is needed is an
increase in demand for goods and services. Investment is one component of demand, and…

- The paradox of saving revisited You should be able to complete this question without doing any algebra, although you may find making a diagram helpful for part (a). For this problem, you do not need to calculate the magnitudes of changes in economic variables—only the direction of change. a. Consider the economy described in Problem 8. Suppose that consumers decide to consume less (and therefore to save more) for any given amount of disposable income. Specifically, assume that consumer confidence (c0) falls. What will happen to output? b. As a result of the effect on output you determined in part (a), what will happen to investment? What will happen to public saving? What will happen to private saving?

Analytic Question on Durable Consumption It is known that durable consumption is more sensitive to interest rates and expected income. In this question, we investigate if this is the case in the context of the model we have been studying. We investigate the following decision: U (c1, c2) 1 max {c1,c2} 2 VCi + xo + subject to the following budget constraints: The time 1 budget constraint: a = Y1 - Ci and the time 2 budget constraint: C2 = Y2 + (1 +r) a. The novelty is that ro is now a variable to represents past purchases of goods 1. You can think of this as a car. In turn, we have that x1 = c1 so a1 is consumption derived utility in period 2 derived from past purchases. For this question assume that B (1+ r) = 1. Answer the following questions. а.
