Beginning with the third quarter of this year, the BEA plans to report the U.S. GDP and national income accounts on a new basis. One of the purposes of the change is to better reflect the importance of intellectual capital and technological innovation in the modern economy. These changes are expected to cause the reported value of GDP to be about 3% higher than when calculated under the present system. I have been thinking about how I would explain these changes to an undergraduate economics class, and this is what I came up with.

The contributions of Reinhart and Rogoff
With all the heated discussions of the last two weeks, it is important to keep perspective on which issues are in dispute and which are not. Let me state plainly something on which I think we ought to be agreed: Carmen Reinhart and Ken Rogoff’s 2009 book, This Time Is Different: Eight Centuries of Financial Folly, is a valuable work of scholarship that continues to deserve study and praise from any thinking person. Here I review some of my reasons for saying that.
Another mediocre GDP report: is this the new normal?
The BEA released today its estimate of 2013 first-quarter real GDP, which grew at a 2.5% annual rate from the previous quarter. That’s below the average 3.1% growth rate since World War II, but better than the 2.1% average since the recovery began in 2009:Q3.
Reinhart-Rogoff and Herndon-Ash-Pollin: a few further comments
I made some comments on Sunday about a recent critique by Thomas Herndon, Michael Ash, and Robert Pollin of an influential 2010 paper by Carmen Reinhart and Kenneth Rogoff. Yesterday Econbrowser hosted a
reply from Pollin and Ash to my remarks. Here I would like to add a few further thoughts on this discussion.
Reply to Prof. Hamilton regarding “Reinhart-Rogoff Data Problems”
Today Econbrowser hosts this guest contribution from Robert Pollin and Michael Ash of the Department of Economics and Political Economy Research Institute (PERI) at the University of Massachusetts-Amherst.
Reinhart-Rogoff data problems
The methods and conclusions of an influential paper by Carmen Reinhart and Kenneth Rogoff published in 2010 have recently been challenged by Thomas Herndon, Michael Ash, and Robert Pollin. Here I comment on both the details and broader significance of the dispute.
Growing student debt
I was curious to take a look at the growing student debt load and the government’s exposure to potential repayment issues.
Who is holding all those U.S. dollars?
If recent trends continue, in a few months there will be $1.2 trillion in Federal Reserve notes (otherwise known as dollar bills) in circulation. Who is holding all these?
2013 Econbrowser NCAA tournament challenge
Despite much bracket-busting, the nation’s best college basketball team seems somehow to have emerged as winner of the 2013 men’s NCAA basketball tournament. Congratulations to Louisville, and congratulations to budwysor, who won the coveted championship of the 2013 Econbrowser NCAA tournament challenge, in part by picking not only Louisville as winner but also 5 of the last 8 teams standing. Thanks to all the others who participated. And if things didn’t go your way, there’s always next year!
