CDC-totallers

Based on little research and an extreme approach to risk management, the CDC now recommends "that women who are pregnant or might be pregnant not drink alcohol at all." The Times writeup is here. Emily Oster, whose excellent book includes a chapter on this issue, has weighed in:

ACA and employment

The Washington Post reports how several recent articles find essentially no effect of the Affordable Care Act (Obamacare) on employment to date among Medicaid populations or part-time workers. The authors point out that long-term effects could differ from the short-term effects that these studies measure, however.

Marriage and health

Last year, Vox posted a helpful summary of a paper on the protective effect of marriage that utilized panel data in the PSID to help control for the selection of healthy people into marriage. The authors found that about half of the protective effects associated with marriage appeared to reflect selection.

Here's a YouTube video presentation about the course by springtime lead DS8 instructor John DeNero, in which I appear at about the 34 minute mark to talk about L&S 88.

But it also seems like a disservice to spin apocalyptical yarns during a period when we should all be taking action on climate change more seriously.

Student loan geography

Vox shows us maps of student loan total debt and delinquencies around Washington, DC.  The two are not the same, revealing that the absolute level of student loan debt is not (at first at least) indicative of trouble.
