Jan Hatzius On Sectoral Balances

by Ramanan on 10 December 2012

Business Insider’s Joe Weisenthal interviewed Goldman Sachs’ Jan Hatzius recently with questions aimed at his usage of the sectoral balances approach:

BI: Back to the balance sheet, multi-sectoral framework of looking at the economy. How did you come to this view? On Wall Street this is still very rare. I don’t see many economist talk about the economy this way, recognizing this identity and making projections based on it. How did you come to see this as the framework by which we should be looking at the economy right now?

HATZIUS: I’ve long been fascinated with looking at private sector financial balances in particular. There was an economics professor at Cambridge University called Wynne Godley who passed away a couple of years ago, who basically used this type of framework to look at business cycles in the UK and also in the US for many many years, so we just started reading some of his material in the late 1990s, and I found it to be a pretty useful way of thinking about the world.

It’s usually not something that gives you the secret sauce at getting it all right, because there are a lot of uncertain inputs that go into this analytical framework, but I do think it’s a reasonable organizing framework for thinking about the short to medium term ups and downs of the business cycle.

Basically, in order to have above trend growth, a cyclically strong economy, you need to have some sector that wants to reduce its financial surplus or run a larger deficit in order to provide that sort of cyclical boost, most of the time.

There are other factors at play in the business cycle – I’m certainly not claiming that ‘this is it!’ – but I have found it to be pretty useful.
