1. Redraw the two panels of figure 13.4, but this time assume that NCO is negative at the world interest rate. Now suppose that the world interest rate increases. What happens to national saving (S)?

Carefully label both diagrams and explain step by step what happens starting from the initial equilibrium in both markets. Make sure to include all the relevant details step by step or you will lose marks.
