1.) Thomas Picketty seems to have made some data errors in his popular book (not too different from Rogoff and Reinhart). Also, the long term trends in wealth inequality seem to be much more complicated than is often suggested.
2.) The VHA, as it turns out, has had a "secret list" to make it's long waiting times not seem so long. Interestingly, many advocates of single payer saw the VHA as a good model for the entire national health care system. Although, it is important to note that the VHA's problems are hardly new. Yet another reason not to support nationalized health care.
3.) A recent meta analysis of studies on the link between saturated fat and heart disease found:
"Current evidence does not clearly support cardiovascular guidelines that encourage high consumption of polyunsaturated fatty acids and low consumption of total saturated fats."
I've long suspected that saturated fat is not as bad as most people believe. This seems to support that view. This is also a good reason to be skeptical of bans and taxes on food deemed to be "unhealthy", as it is often unclear.
4.) I often speak favorably on the concept of cost sharing in health care on this blog. Aaron Carroll provides a different point of view. I'll be the first to admit that cost sharing has its downsides, and that there are times when more cost sharing is not desirable. Still, overall, I think there is too little cost sharing in our system instead of too much.
5.) Textbook example of regulatory capture with Pepsico lobbying for a crackdown on "counterfeit hummus". (HT to Mark Perry)
