		<description><![CDATA[The Atlantic has a very nice article summarising the discussion of whether the flu vaccine prevents death among older people. The basic problem in evaluating interventions like these is self-selection, which can make &#8220;cohort studies&#8221; unreliable. Not really news to most economists, but it seemed to have created quite a fire storm among public health [...]]]></description>

		<description><![CDATA[Apparently the relationship between price and demand seems to be a slippery concept.

The correlation between cost [...]]]></description>

I was stopped on the highway because of traffic when I got rear-ended. I got transported to the ER with a c-collar and on a backboard, but luckily there were no broken bones [...]]]></description>
