Multiple Choice

Which of the following represents the AD curve with a financial friction?

A) $\tilde { Y } _ { t } = \bar { a } - \bar { b } \bar { f } - \bar { b } \bar { m } \left( \pi _ { t } - \bar { \pi } \right)$
B) $\tilde { Y } _ { t } = \bar { a } ( 1 + \bar { b } \bar { f } ) - \bar { b } \bar { m } \left( \pi _ { t } - \bar { \pi } \right)$
C) $\tilde { Y } _ { t } = \frac { \bar { a } } { \bar { b } \bar { f } } - \bar { b } \bar { m } \left( \pi _ { t } - \bar { \pi } \right)$
D) $\tilde { Y } _ { t } = \bar { a } - \bar { b } \bar { m } \left( \pi _ { t } - \bar { \pi } \right)$
E) $\tilde { Y } _ { t } = \bar { a } \times \bar { b } \bar { f } + \bar { b } \bar { m } \left( \pi _ { t } - \bar { \pi } \right)$
