(5 pts) PV = 44000/1.1=40000 b. Using current consumption (C1) and future consumption (C2) graph (x-axis: C1, y-axis: C2) draw Jerry’s budget constraint when the interest rate is 10%. Clearly mark your graph. What is the slope of the budget constraint? (7 pts) C2 = 88000 – 1.1C1 ; The slope = -1.1 c. If the interest rate decreases to 5%, make changes in Jerr...
