A Permanent Increase in the Money Supply
1.the short-run effect
(1)A permanent increase in Ms must ultimately
lead to a proportional rise in E .The rise in Ms
causes Ee to rise proportionally.
(2)Because a rise in Ee, the upward shift of AA1 to
AA2 (permanent) is greater than caused by an
equal, but transitory, increase. (point 3)
(3)Point 2 is above XX CA(point2)>X
The current account improves.
