Recently, Paul Krugman wrote two articles in The New York Times on recent surge in US manufacturing: Making Manufacturing Great Again (June 6, 2023) and Making Manufacturing Greater Again (April 20, 2023).
Post-Keynesians stress the importance of manufacturing and exports/international trade. Before the economic and financial crisis which started in 2007, Wynne Godley was worried about all this and proposed to improve exports and take measures such as imposing non-selective protectionism, as he thought—rightly—that a crisis would happen and fiscal policy should be used and would be used but that alone will not be sufficient. In other words, the market mechanism won’t do the trick.
The reason manufacturing is important is because of the potential for expansion of exports.
Economists however have been denying all this. Especially with the rise of Donald Trump when attempts to improve the US balance of payments/international investment position were looked upon as clownish. But now the establishment has accepted that it needs to be addressed. But they don’t want to accept that they were behind. At the same time, Joe Biden has gone beyond measures that Trump has taken.
However, there are many economists who still live with old dogmas. For example, see Adam Posen’s article America’s Zero-Sum Economics Doesn’t Add Up for Foreign Policy.
So we have two types of mainstream economists: a) those who grudgingly accept that they were wrong and b) who are still wedded to dogmas.
There’s of course a limit to this, so the solution to the problems lie in disbanding the system of free trade and move toward a system of balance-of-payments targets.
