Defining $Y _ { t}$ As Current Output $\bar { Y } _ { t }$

True/False

Defining $Y _ { t}$ as current output, $\bar { Y } _ { t }$ as potential output, and $\tilde { Y } _ { t }$ as short-run fluctuations, the text uses the following equation to measure the fluctuations component of output: $\tilde { Y } _ { t } = \frac { Y _ { t } + \bar { Y } _ { t } } { Y _ { t } }$ .
