Consider the IS curve $\tilde { Y } _ { t } = \frac { 1 } { 1 - \bar { x } } \times \left[ \bar { a } - \bar { b } \left( R _ { t } - \bar { r } \right) \right]$ . If there is no demand shock and $\bar { b } = 2$ And $\bar { x } = 0.5$ , a 1 percent increase in the real interest rate causes short-run output to:
A) fall by 2 percent
B) rise by 4 percent
C) fall by 4 percent
D) fall by 0.5 percent
E) Not enough information is given.
