The answer to the question posed in the title is No! Lawrence Summers’ macroeconomic assessment does not stack up. In – Is the $US900 billion stimulus in the US likely to overheat the economy – Part 1? (December 30, 2020) – I developed the framework for considering whether it was sensible for the US government to provide a $US2,000 once-off, means-tested payment as part of its latest fiscal stimulus. Summers was opposed to it claiming that it would push the economy into an inflationary spiral because it would more than close the current output gap. Today, I do the numbers. The conclusion is that there is more than enough scope for the Government to make the transfers without running out of fiscal space.
