Multiple Choice

Defining $Y _ { t }$ as current output, $\bar { Y } _ { t }$
As potential output, and $\tilde { Y } _ { t }$
As short-run fluctuations, which of the following equations is correct?

• A) \(Y _ { t } = \tilde { Y } _ { t } - \bar { Y } _ { t }\)
• B) \(\tilde { Y } _ { t } = Y _ { t } - \bar { Y } _ { t }\)
• C) \(\tilde { Y } _ { t } = \bar { Y } _ { t }\)
• D) \(\bar { Y } _ { t } = 0\)
• E) \(\tilde { Y } _ { t } = \frac { Y _ { t } + \bar { Y } _ { t } } { \bar { Y } _ { t } }\)
