the table below, showing hypothetical measures of real GDP in the coming

Now fill in the remaining columns of the table by answering the following
questions.
(a) What is potential output in 2018? You could call this a trick question,
since there's no way for you to know the answer! In a way, that's the main
point: fundamentally, we have to take some other measurements and make
some assumptions. Suppose your research assistant tells you that in 2018,
business surveys, unemployment reports, and recent years' experience sug-
that the economy is operating at potential output. So go ahead and
write 18.0 for potential in this year.

(b) Assume potential output grows at a constant annual rate of 2.5%, and
complete the remainder of the table.
(c) Comment on the state of the economy in each year. When does the
economy enter a recession? When does the recession end?
(d) How is your answer in part (c) related to the growth rate of actual output
in the last column of the table?
