Dct = –0.205
+
0.809Dyt
– 0.457 ct-1+ 0.263yt-1 +
t





(0.121)
(0.128)
(0.129)

(0.126)


where c is the log of real consumption, y isthe log of real GDP, and D
is the first difference operator. The following statistics anddiagnostics are also computed for this regression model: Adjusted-R2 =0.517; Breusch-Godfrey Test ~= 1.31; Bera-Jarque Test ~
= 9.88.
