Part B: Suppose you are given y > 0, y2 = 0, a = 0, r > 0. What would happen to the opportunity set if i) the first period endowment y increases or ii) the market interest rate (r) decreases? You should answer this question by drawing a figure (you can use pen and paper). Be sure to define the intercepts and slope of the opportunity set in each case. Please also answer this question in general terms.
