The cause for a parallel shift in the budget constraint.
Answer to Problem 1CQQ
Option 'd' is correct.
Explanation of Solution
Option (d):
The budget constraint is the constraint which is due to the budget of the individual. The human wants and needs are unlimited and when the budget of the individual is not unlimited, it will lead to the constraint of needs and this constraint raised due to the limited budget is known as the budget constraint of the individual. Thus, a budget constraint will represent all the possible combinations of two commodities that an individual can consume at the given market prices and with all his income in hand.
Here, the budget of the consumer is $100, the
Option (a):
When price of the items falls to half of the previous level along with the income, there will be no change in the quantities demanded and thus there will be no shift in the budget constraint which means that option 'a' is incorrect.
Option (b):
When price of the items increases to twice of the previous level and the income remains the same, there will be a decline in the quantities demanded and thus there will an inward shift in the budget constraint which means that option 'b' is incorrect.
Option (c):
When there is an increase in the income to $120 and the decrease in the price levels of soda to $1 and the pizza to $8 take place, these will lead to an unparallel shift in the budget constraint which means that the option 'c' is incorrect.
Concept introduction:
Budget constraint: It represents all the combinations of two goods that the consumer can consume with the given price level and the income in the hands of the individual.

- Question No. 5| Hafidh's income is $200 a month. The price of watch is $25 a show, and the price of a Jeans is $15. a) Calculate the equation for Hafidh's budget line b) Draw a graph of Hafidh's budget line with the quantity of Watches on the x-axis. c) If Hafidh's income increased from $200 to 350$. Explain and show how Hafidh's budget line changes with watches on the x-axis.arrow_forwardA consumer has income of $3,000. Wine costs $3 per glass, and cheese costs $6 per pound. Make a graph. Draw the consumer’s budget constraint with wine on the vertical axis. Make sure to label the axes.arrow_forwardA consumer has income of $3,000. Fresh Juice costs $3 per glass, and cheese costs $6 per pound. (a) Draw the consumer's budget constraint (put cheese on the horizontal axis). What is the slope of this budget constraint? (b) The price of cheese rises from $6 to $10 per pound, while the price of Fresh Juice remains $3 per glass. For a consumer with constant income of $3,000, show what happens to consumption of Fresh Juice and cheese (assuming both are normal goods). Decompose the change into income and substitution effects. Be sure to clearly mark all relevant information in your diagram.arrow_forward
- 6. Consumer spends $360 per week on two goods, X and Y. PX=$ 3 and PY=$2. His utility function is U= 2X2Y. What quantities of X and Y does he buy each week in equilibrium?.arrow_forwardEXERCISE 3 If Joe decides to allocate his entire weekly allowance between energy drinks and coffee, he could afford 9 energy drinks and 3 cups of coffee, or 6 cups of coffee and 2 energy drinks. Suppose a cup of coffee costs £2.80. Calculate the price of an energy drink and Joe’s weekly allowance. Write down Joe’s budget equation and draw the corresponding budget line. Mark the two consumption bundles mentioned above. In your graph, clearly label the axes, the budget line, and calculate the coordinates of the points of intersection of the budget line with each axis. Interpret each of those points. Discuss how Joe’s budget set would change if his allowance was reduced by £5.20 a week. Show the relevant changes graphically. How should the price of coffee change so that Joe could still afford to buy 6 cups of coffee and 2 energy drinks? Discuss how Joe’s budget constraint would change if the government subsidised consumption of coffee by £0.50 per cup of coffee.arrow_forwardJamani earns a weekly income of $6000. Suppose he wishes to spend this income on two goods, games and DVDs only. A game costs $200 while a DVDcosts $600. Draw Jamani’s budget line. Putting games on the Y axis. ii. Suppose his income increases to $9000 per week, illustrate what happens to her budget line.iii. Suppose the price of games increase to $600, while his income and the price of DVDs is unchanged from part (i).arrow_forward
- Jerry spends his entire budget on bread and gasoline. His preferences are complete, transitive, monotonic, and convex. For Jerry, bread is an inferior good that follows the law of demand. Moreover, his cross-price elasticity of demand for gasoline with respect to the price of bread is negative. Suppose the price of bread increases, all else constant. a. Create a chart to show the total, income, and substitution effects on bread and gasoline of the increase in the price of bread. b. Use budget lines and indifference curves to graphically illustrate the three effects. Be sure to label each effect on your graph (or through the chart from part a) and plot bread on the x-axis and gasoline on the y-axisarrow_forwardurgent pleasearrow_forward10- 8 Quantity of D A 6 2 0 2 6 8 10 4 Quantity of C Refer to the budget line shown in the diagram.
