4. A researcher wanted to evaluate
UK’s exports (Y) using data for the period 1948 to 1984. He
obtained the following regression results (standard error in
parentheses):
se= (12.5) (0.080)
(t=)
(-2.35)
The 5% critical
value
is -2.95 and the 10% critical
value
is -2.60.
se =
(5.06)
(0.236) (0.163)
(t=)
(-5.89)
where
is the second
difference operator, that is the first difference of the first
difference.
What can you conclude about the stationarity of the time series
in
question?
