Eric buys only milk and cookies. In year 1, Eric earns $90, milk costs $2 per quart, and cookies cost $3 per dozen. Use the green line (triangle symbol) to draw Eric's budget constraint on the following graph.
Now suppose that all prices increase by 10 percent in year 2 and that Eric's salary increases by 10 percent as well.
Use the blue line (circle symbol) to draw Eric's new budget constraint on the preceding graph.
True or False: Eric will consume more milk and fewer cookies in year 2 than in year 1.
True
False.
Currently, Paula is maximizing utility by purchasing 5 TV dinners (T) and 4 Lean Cuisine meals (L) each week.
Graph Paula’s initial utility-maximizing choice.
Suppose that the price of T rises by $1 and the price of L falls by $1.25. Can Paula still afford
to buy her initial consumption choices? What do you know about her new budget constraint?
Use your graph to show why Paula will choose to consume more L and less T given her new budget constraint. How do you know that her utility will increase?
Some economists define the ‘‘substitution effect’’ of a price change to be the kind of change shown in part c. That is, the effect represents the change in consumption when the budget constraint rotates about the initial consumption bundle. Precisely how does this notion of a substitution effect differ from the one defined in the text?
If the substitution effect were defined as in parts, how would you define ‘‘the income effect’’ to get a complete analysis of how a person responds to a…
Assume that Sara has $800 per month to divide between playing golf and playing paint ball . Assume Golf costs $40 and paintball costs $80 . Suppose Sara plays golf eight times per month and plays paintball six times per month .
Draw Sara’s budget constraint
Assume Sara has new expenses and can spend $320 only this month. Draw the new budget constraint
As a result of a decrease in income Sara decides to play 11 rounds of golf and two games of
paintball . what kind of a good is paintball ? what kind of a good is golf?
Assume Sara has $400, the price of paintball is still $40 , but the price of Golf doubles , draw the new budget constraint

- Why does a change in income cause a parallel shift in the budget constraint?arrow_forward1. Gertrude had a weekly income $9. At that time, a bulla sold for $1 and a drink for $1.50. a) What is Gertrude's real income in terms of bullas? b) What is her real income in terms of drinks? c) What is the relative price of a drink (in terms of bullas)? d) Sketch Gertrude's budget constraint (placing drinks on the vertical axis). e) Suppose she chooses to consume 3 bullas and 4 drinks per week. Is she satisfying her budget constraint? f) Sketch the budget line if the price of bullas rises to $2 and all other values remain unchanged. g) Sketch the budget line if the price of drinks rises to $3 and all other values remain at their original levels. h) i) Sketch the budget line if Gertrude gets a raise to earn $18 a week and prices remain at their original levels. Supposes all changes take place together: the price of bullas rises to $2, the price of drinks rises to $3, and Gertrude gets a raise to earn $18 a week. How does the new budget line compare to the original one?arrow_forwardBy definition, a budget constraint shows the consumption bundles that a consumer can afford. Assume that a college student spends her income on mac-n-cheese and CDs. The price of one box of mac-n-cheese is $1.00, and the price of one CD is $10.00. If she has $90 of income, she could choose to consume 30 boxes of mac-n-cheese and 7 CDs 25 boxes of mac-n-cheese and 6 CDs 25 boxes of mac-n-cheese and 8 CDs 10 boxes of mac-n-cheese and 9 CDsarrow_forward
- Ray buys only hamburgers and bottles of root beer out of a weekly income of $100. He currently consumes 20 bottles of root beer per week, and his marginal utility of root beer is 6. The price of root beer is $2 per bottle. Currently, he also consumes 15 hamburgers per week, and his marginal utility of a hamburger is 8. Is Ray maximizing utility at his current consumption basket? If not, should he buy more hamburgers each week, or fewer?arrow_forwardIf 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. a) 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. b) 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? c) Discuss how Joe's budget constraint would change if the government subsidised consumption of coffee by £0.50 per cup of coffee.arrow_forwardPeter loves spicy food. He consumes both Laoganma chili crisp and Texas Pete hot sauce. His annual budget curve maps from (20 bottles of Laoganma, 0 cups of Texas Pete) to (0 bottles of Laoganma, 24 bottles of Texas Pete). a) Draw his budget constraint. Express the price of Texas Pete, in terms relative to the price of Laoganma. b) Given this set up, would Peter ever consume at the following points of (#bottles of Laoganma, #bottles of Texas Pete)? Why/why not? If we would consume at this point, draw an indifference curve that would justify this decision.i) (12, 12) ii) (6, 15) iii) (6, 6) iv) (12, 10) c) Imagine that Peter consumes 4 bottles of Laoganma.
