Bangkok - There's an old saying among economists: "When the US catches a cold, the rest of the world catches pneumonia."
"But nobody says what happens when the US catches pneumonia," said Ammar Siamwalla, a respected Thai economist. "You don't catch a cold, but I don't know what happens."
That indeed is the billion-dollar question for Asia in 2009.
Most of Asia's dynamic emerging economies have been using exports as their engines of growth for the past decade or more.
If anything, the region became even more export-dependent in the aftermath of the 1997 Asian financial crisis, Asia's version of the meltdown that is now shaking the advanced economies.
