Week 6 Chapter 4: The theory of Individual Habit

Question 1 ) Page 154 ( which includes modifications)

Someone has 300 dollar to spend upon goods By and Y. The market prices of these two goods happen to be Px sama dengan \$15 and Py = \$5.

a. Draw the budget constraint. i actually. e provide a carefully branded diagram w. What is industry rate of substitution? Give an presentation. c. Illustrate the card holder's opportunity placed in part a) above. g. Show the way the consumer's prospect set changes if salary increases simply by \$300. at the. Does the increase of cash flow by \$300 in part d) above customize market charge of alternative between goods X and Y? Answer:

a. The entire budget is definitely \$300. Px and Py are used to stand for market prices of two goods x and con. Hence, 300=15X+5Y. Now in case the entire spending budget money can be spent on great X, after that Y=0, X=20. Also, if the entire finances money is usually spent on very good Y, then simply X=0, Y=60. So the optimum amount of good X can be 20 plus the maximum amount of good Sumado a is 62. Steps:

1 . 300=15X+5Y

installment payments on your Y=-3X+60, in the event X=0, in that case Y=60

several. X=-(1/3)Y+20, if Y=0, in that case X=20

some. So Points (0, 60) and (20, 0) take the competition

Therefore , The budget constraint diagram can be driven and is demonstrated as stick to:

b. Industry rate of substitution is a rate where good Times (or very good Y) may be traded forever Y (or good X) in the market. Is it doesn't slope with the budget collection. So whenever we calculate the slope with the budget series above, we can make the market level of substitution in this case. Methods:

1 . The Slope of budget line= (M/Py)/(M/Px)= Px/Py

2 . Px/Py=15/5=3

3. As a result, the market level of substitution in this case is definitely 3.

Interpretation: This means that in order to get one unit of good Back button, we have to quit three devices of good Sumado a. This reflects the meaning of substitution. c. The opportunity arranged (also called the budget set) is a bundles of products a consumer can pay for. This means that in such a case consumer can get different quantity combinations of good X and good Con within the limit of \$300. So in the diagram the opportunity set is a shadow region below the spending budget line.

m. If salary changes by simply \$300, then your entire budget of the client goes to \$600. Then the the same changes to 3X+Y=120. So the plan may in order to as stick to:

The budget line shifts out parallel to its self. The area underneath the new price range line is definitely greater than prior to as shown by the extra area in brown. e. No, expense change the industry rate of substitution since an increase in spending budget can only modify income, it will not change the value of goods. And so the slope in the budget range will not change. Thus, industry rate of substitution in cases like this will not change.

Question three or more (with some modifications towards the question). On-page 155 1 . Bottom of Form

Someone must dedicate \$600 between consumption of product Times and Sumado a. The relevant marketplace prices will be Px = \$10 and Py sama dengan 40. a. Write the formula for the consumer's budget line

b. Illustrate the consumer's prospect set in a carefully labeled diagram. c. Show how a consumer's option set adjustments when the price of good By increases to\$20. d. Will the change in the cost of good Back button in part c alter the marketplace rate of substitution between goods X and Y?

Instructions: For every part of the over question, show your work. Charts may be beneficial. Explain and have absolutely all steps of how you have reached the answer. Don't just state the answer. Response:

a. Now we know that the whole amount of income is usually \$600. As well as the price great X can be \$10, the price of good Sumado a is \$40. So The equation for the consumer's finances line is given as: 600=10X+40Y

Also, we are able to simplify the equation then we get X+4Y=60

b. To demonstrate the opportunity set, we can merely maximum every amount of good X and Y while shown under. Steps:

1 . X+4Y=60

installment payments on your X=-4Y+60, in the event that Y=0, in that case X=60

several. Y=-(0. 25)X+15, if X=0, then Y=15

4. Therefore the points (0, 15) and (60, 0) are on the curve

As a result, we can bring the picture of spending budget line because follow:

Hence the opportunity emerge this case is definitely the shadow area shown previously mentioned....
