Tidbids: Correlation and Causation (Redux)

April 5, 2009

Almost every major study of the impact of breast feeding on infant health purports to show tremendous benefits.  It now seems as if these studies are deeply flawed.  They implicitly assume breast-feeding mothers do not differ from non-breast-feeding mothers in any substantive way that could affect the health of their babies.  Not so.  (They also neglect the opportunity cost of the mother’s time.)

Here is a link exploring the issue (which contains a link to a longer Atlantic article by Hanna Rosin): Case Against Breast Feeding.

I am introducing a new category to the blog — Tidbits.  These entries will contain random things I find interesting that do not quite rise to the level of “Further Study” — either because they don’t really have to do with 335/402 or because they aren’t really substantive (just interesting).

Testing the explanatory power of equilibrium and New Keynesian models by looking at the cyclical properties of consumption, investment, real wages, etc. may not prove dispositive.  So let’s look at candy — the ultimate countercyclical nondurable good: When Economy Sours, Tootsie Rolls Soothe Souls.
