Before the Pool Room, a quick comment on Australia’s recent 0.4% growth in GDP in the first quarter of 2009–largely due to a surprise growth in net exports–and the sequel the next day of a surprise trade deficit.
Briefly, the “textbook” definition of GDP is:
GDP = C+I+G+X‑M
“GDP equals Consumption plus Investment plus Government spending plus eXports minus iMports”
M fell by 9 billion, X (more on this below) fell by 3 billion, so there was a +6 billion turnaround in the “net exports contribution to GDP” (as it’s known).
