In the long run, the higher saving rate leads to a higher level of productivty and income, but not to higher growth in these variables.
Catch-up effect : Countries that start off poor tend to grow more rapidly than countries that start off rich
Y=C+I+G S=I S=(Y-T-C) + (T-G) = private saving – public saving.

Government deficit = reduces national saving = reduces NCO. NCO reduced = money supply reduced = exchange rate goes up. CAD appreciates = fall in net exports
Net export = source of demand of CAD. More export =
