Model this taper and show your work, if only verbally

Shortly following the announcement of a delayed taper:

The rupee rallied 2.8 percent to 63.4950 per dollar, according to prices from local banks compiled by Bloomberg. Thailand’s baht rose 1.2 percent to 31.850, the Philippine peso gained 1.4 percent to 43.87 and Malaysia’s ringgit appreciated 1.2 percent to 3.29. Global funds pumped $5.7 billion into the stock markets of India, Indonesia, the Philippines, South Korea, Taiwan and Thailand this week, according to exchange data.

Pay special heed to quantitative magnitudes.  For how long are we delaying the taper?  One or two months?  How much is the taper anyway, relative to the stock of relevant financial assets?  Taking $10 to $15 billion off of $85 billion a month in purchases, when the asset stocks are in the trillions?  Woo hoo.

Here are some interesting comments from Stephen Jen.

I’ll say it again: none of you understand what is going on here, and neither do I.  I am not seeing enough admission of this basic fact.

Addendum: Scott Sumner offers a response.
