Richard Koo on global stagnation, globalisation and the trade war

In the short video below, Richard Koo, originator of the idea of balance sheet recessions, argues that the current global economic stagnation is largely due to private sector firms as a whole in most of world’s largest economies acting as net savers rather than net borrowers and investors, despite very low interest rates. This is weakening aggregate demand and is compounded by the failure of the other sectors in the major economies, namely households and governments, to compensate by borrowing and spending to counter this weakness.

Of course, the US government is running a budget deficit, which has sustained moderate growth there, but for the largest economies taken together, private sector saving is proving to be a drag on continued recovery.

Koo doesn’t go into the reasons for this behaviour, although he has argued elsewhere that the private sector in many countries is attempting to save in order to pay down high levels of debt, producing a balance sheet recession, or stagnation at best. Fiscal policies that boost demand as well as policies that increase private investment opportunities in general would help to counter this.

He also touches on the US-China trade war as adding to global weakness, and notes that it is unlikely to end anytime soon, due to the job losses in the US which decades of current account deficits have reflected. As Koo puts it, free trade has created enough losers economically to make it a political problem in the US, and one that contributed to the election of Trump.

Aside from the trade war, it is quite likely that rising inequality has contributed to global weakness. With much of the income from economic growth accruing to the already wealthy, who save a larger proportion of it than poorer groups, significant increases in consumption in advance of the financial crisis relied on higher household debt since it is less able to be supported by rising wages for the majority.

In economies such as Germany and Japan, the result has been weaker growth, rising public debt in Japan, and a soaring current account surplus in Germany, while in the US and UK the result has been higher household debt and current account deficits. These trends sustained each other for some time, but the resolution of such imbalances may well be the source of much of the current global turmoil which has followed the crisis of more than a decade ago.

This interpretation suggests a need for policies which reduce inequality and increase wages, boosting consumption in a more sustainable fashion, and therefore increasing private investment opportunities. Greater public investment in infrastructure would also help. In a number of countries this has been constrained by policies focusing on austerity and reducing public debt, which have in many ways proved economically and socially damaging.

  1. Thanks for this excellent post. Thanks also for posting a video in which – rarely enough – the fetish of free trade is challenged.
