Suppose we have a household with the following lifetime utility function: U = InC, + BInCH1 a) Please compute indifference curves numerically in an excel file. Suppose that B = 0.95. Create range of values of C, from 0.5 to 1.5, with a space of 0.01 between (i.e., create a column of potential C values ranging from 0.5, 0.51, 0.52, 0.53 and so on). For each value of C, solve for the value of C, which would yield a lifetime utility level of U =0 . Plot this. b) Re-do part (1), but for values of lifetime utility of U =-0.5 and U = 0.5. c) Verify that "northeast" is the direction of increasing preference and that the indifference curves associated with different levels of utility do not cross
