The following data pertain to products A and B, both of which are purchased by Jay. Initially, the prices of the products and quantities consumed are: PA = $10; QA = 3; PB = $10; QB = 7 Jay has $100 to spend. After a reduction in price of B, the prices and quantities consumed are: PA = $10; QA = 2:5; PB = $5; QB = 15 Assume that Jay maximizes utility under both price conditions above. Also, note that if after the price reduction enough income were taken away from Jay to put him back on the original indifference curve, he would consume this combination of A and B: QA 1:5; QB = 9 Determine the change in consumption of good B due to the (1) the substitution effect and (2) the income effect using Hicks decomposition.arrow_forward

Does John show diminishing marginal utility for Coke, or does he show increasing marginal utility for Coke? Supposethat John has $3 in his pocket. If Cokes cost $1 each and John is willing to spend one of his dollars on purchasing a first can of Coke, would he spend his second dollar on a Coke, too? What about the third dollar?

- Suppose you expect to earn $10 this year and $10 next year. Each dollar you earn this year can be either spent, or saved at an interest rate of 10%. If you want to spend more than $10 this year, you can borrow money at 10% interest and repay it next year. Next year, you plan to pay oyour debts (if any), then spend all your earnings and all your savings (if any). Draw your budget line between “dollars spent this year" and “dollars spent next year". Suppose the government imposes a 50% income tax on all your earnings this year and next year (not including your interest earnings). Draw your new budget line. Suppose the government imposes a 50% sales tax on everything you buy this year and next year. Draw your new budget line.

Suppose Jill derives utility from not only consuming goods, but also from enjoying leisure time. Let her utility function be defined as follows: U=C.25.R.75 where C is a consumption good that can be bought at a price of $1 and R is hours of leisure (relaxation) consumed per day. There are 24 hours in a day and leisure is defined as time spent not working.
