A useful short paper by post-Keynesian economist Jan Kregel of the Levy Institute, focusing on the nature and causes of global financial and trade imbalances, and how they might be resolved in a way that supports global growth and employment.
Kregel argues that in today’s global economy, financial flows dominate trade flows, and are the cause of significant capital account imbalances, which drive concomitant current account imbalances.
Trade policy, such as the imposition of tariffs, and escalating trade wars, are unlikely to resolve these imbalances. On the contrary, controls on capital flows would be much more effective. An alternative to this is Keynes’s original proposal for an international clearing union, able to create liquidity not based on a national currency such as the dollar, and promote international cooperation. This seems a long way off in today’s world.
All this is along the lines of arguments made by Michael Pettis, whose ideas I refer to often on this blog. However, Pettis also links global imbalances to national savings behaviour, so that a ‘savings glut’ not invested domestically in one country can be exported abroad, and can create financial bubbles and rising debt, potentially leading to stagnation or crisis in the longer term.
Thomas Palley, a post-Keynesian economist, here provides a critique of recent policy proposals by US Democratic politicians employing some ideas from Modern Monetary Theory. They variously want to fund programmes such as universal healthcare and a ‘Green New Deal’, financed to a large degree by increased government borrowing.
MMT, as a set of ideas, is an offshoot of post-Keynesianism, but is perhaps more straightforward to grasp when it comes to budget deficits and its opposition to austerity; hence its current popular appeal. Continue reading →
The Levy Institute is officially non-partisan, but tends to publish in the spirit of post-Keynesian thinking. The late Hyman Minksy and Wynne Godley spent the latter part of their lives working there and Godley helped build their macroeconomic model of the US economy.
This year, the 14-page report is titled Can Redistribution Help Build a More Stable Economy? In short, the authors examine what they see as the four key constraints on the US economy and which account for the historically lengthy but weak recovery: (1) weak net export demand; (2) fiscal conservatism; (3) increasing income inequality; and (4) financial fragility. These four constraints help to explain the weak performance, as well as some of the political developments of recent years. Continue reading →
What is the link, if any, between wages and technological progress in a capitalist economy? An article in this week’s The Economist magazine sheds some light on the issue. In particular, it considers the apparently lesser-studied effect that wages might have on productivity growth.
The reverse relationship, that productivity growth allows growth in wages, is studied more often. This has certain implications for economic policy. Boosting the supply-side determinants of innovation, such as education, and research and development, become important.
But what of the demand-side? The article mentioned above describes how some economic historians are engaged in a debate over the “high-wage hypothesis” put forward by Robert Allen, which he suggests helped drive industrialisation in Britain. Continue reading →
2018 marks 24 years since I first took an interest in what is sometimes referred to as the ‘dismal science’. Not a particularly notable landmark, though it is more than half my life. And I certainly have not spent all that time with my nose in books about economics, although I have spent quite a bit of it like that, maybe more than is good for me.
Apparently it was the Victorian historian Thomas Carlyle who coined the phrase dismal science in the 19th century. I am sometimes inclined to agree, when observing a malfunctioning economy and its malfunctioning stewards in government and business. But more often I am prepared to be optimistic that we can find solutions to the problems of humanity. Some of them might even come from studying economics!
Keynes looked forward to a time when the economist’s role in society would be akin to that of dentists, as humble, competent fixers of minor problems. Notwithstanding a call from the UK’s current environment secretary during the campaign for Brexit to pay less attention to experts, economists and their ideological categories of supply, demand and growth have become extremely powerful and accepted, even if with passivity, resignation or incomprehension.

The aim of QE is to reduce long-term interest rates, boost private sector lending, and raise asset prices to generate a positive wealth effect on private spending. Altogether, these are meant to raise private sector consumption and investment, and thus economic growth.
Richard Koo, economist at Nomura and originator of the theory of balance sheet recessions, has outlined the potential problem of the ‘QE Trap’ (2015). While QE might have the effect of mitigating such a recession, once the recovery is underway, its withdrawal could lead to slower growth than otherwise. In other words, over the longer term, its overall effect might be negligible or even negative: Continue reading →
Keynesian economics emphasises the primacy of aggregate demand or expenditure in driving the growth of output and employment. More mainstream neoclassical Keynesians, and the New Keynesians, tend to argue that inadequate demand is a short run phenomenon. The more radical post-Keynesians argue that it can be a problem in the long run too.
To varying degrees, these economists make the case for demand management via some combination of monetary, fiscal and exchange rate policy. The more radically minded have also long argued for incomes policies to manage wage and price inflation, and reform to the international monetary system in order to allow national governments the space to manage demand and promote full employment while preventing excessive and destabilising current account imbalances.
While Keynesian economics focuses on demand and, traditionally, macroeconomics, industrial policy aims to impact more on the supply-side of the economy and draws on microeconomics. Continue reading →
