The World Needs A Kaldorian Response

Dani Rodrik has a new article, The Abdication Of The Left written for Project Syndicate. He says:

The good news is that the intellectual vacuum on the left is being filled, and there is no longer any reason to believe in the tyranny of “no alternatives.” Politicians on the left have less and less reason not to draw on “respectable” academic firepower in economics.

Consider just a few examples: Anat Admati and Simon Johnson have advocated radical banking reforms; Thomas Piketty and Tony Atkinson have proposed a rich menu of policies to deal with inequality at the national level; Mariana Mazzucato and Ha-Joon Chang have written insightfully on how to deploy the public sector to foster inclusive innovation; Joseph Stiglitz and José Antonio Ocampo have proposed global reforms; Brad DeLong, Jeffrey Sachs, and Lawrence Summers (the very same!) have argued for long-term public investment in infrastructure and the green economy. There are enough elements here for building a programmatic economic response from the left.

This is fine, but it wouldn’t be enough to solve the world’s problems because the world as a whole is balance-of-payments constrained as most individual nations are. What is needed is a coordinated response at the international level – a concerted action.

In his 1984 book Causes Of Growth And Stagnation In The World Economy, Nicholas Kaldor wrote:

I should like to end this series of lectures by suggesting the outline of a world-wide agreement on the necessary policies for recovery. The programme could be summed up under four main heads:

  1. The first is coordinated fiscal action including a set of consistent balance of payments targets and “full employment” budgets.If this does not prove to be politically feasible, it is inevitable that the growth of unemployment will sooner or later force governments to take measures that would make it necessary for them to expand demand without being frustrated by the inevitable balance of payments consequence of expanding their economies relative to their trading partners. This means that there needs to be some form of restriction that would limit the increase in “competitive” imports to some target ratio in relation to exports. Trade liberalisation, which played such an important part in the rapid economic progress during the years of expansion, becomes a serious obstacle to economic recovery in the case of prolonged stagnation due to the inability of countries to achieve a coordinated set of policies. But, given a proper recognition of the problem, that under conditions of unrestricted free trade the actual volume of production and trade may in fact be considerably less than under some system of regulated trade – a system which relates the volume of imports in manufactures from a particular group of countries, such as the members of the EEC, to some mutually agreed ratio to the exports of individual members to the rest of the group – there is no reason why full employment should not be restored through policies of expansion, preferably directed by the expansion of State investment. This coordinated action by all countries, instead of isolated actions by each country, is the first and most important requirement of recovery.

At present all countries have fairly large deficits in the general government budget, but these are largely the consequence of the low level of activity. On a “full employment” basis they would show a highly restrictive picture – they would show surpluses and not deficits. Contrary to appearances, the requirement of stability is for expansionary budgets with lower taxes and higher expenditure, and not further fiscal restriction (as is advocated, for example, by M. de Larosiere of the International Monetary Fund).

Before the crisis, the economics profession believed in two orthodoxies:

  1. crude version of Monetarism, which treats the stock of money as exogenous and also claims that fiscal policy is impotent.
  2. free trade.

While policy response following the 2008 crisis have made economists realize that the first orthodoxy is wrong, they are yet to realize the orthodoxy of the second. As Joan Robinson said in her 1973 article, The Need For A Reconsideration Of The Theory Of International Trade, “there is no branch of economics in which there is a wider gap between orthodox doctrine and actual problems than in the theory of international trade”. The recent consensus of the economics profession on the debate about the UK EU referendum highlights it. Instead of the invisible hand, we need a visible hand, i.e., a coordination at the international level. The leftist response as highlighted by Dani Rodrik are welcome but still leave the problem open. So one needs both this and a world-wide fiscal expansion with balance-of-payments targets.
