LO 2,5 A consumer receives income y in the current period and income y' in the future period, and pays taxes of t and t' in the current and future periods, respectively. The consumer can borrow and lend at the real interest rate r. This consumer faces a constraint on how much he or she can borrow, much like the credit limit typically placed on a credit card account. That is, the consumer cannot borrow more than x, where x < we-y+t, with we denoting lifetime wealth. Use diagrams to determine the effects on the consumer's current consumption, future consumption, and saving of a change in x, and explain your results.arrow_forward
