I didn’t want to clutter my post on PM Truss’s economics with detailed references but in case anyone is interested:-
A paper ‘Do corporate tax cuts boost economic growth?’ in the August 2022 European Economic Review by Sebastian Gechert and Philip Heinberger found no evidence that they did. Instead they found evidence of a publication bias, with positive results more likely to be published. The authors point out the complexity of the relationship and therefore the lack of surprise that it is difficult to find a straightforward causal relationship. In the UK context, my view is that it is very unlikely that cutting our rate will have anything but a negative impact: our corporate tax rate is not high compared to other countries, and cutting it in the midst of a full blown fiscal crisis is unlikely to boost investment or growth.
The evidence on personal tax is even clearer, as David Hope of LSE argues in a December 2020 paper: ‘Keeping tax low for the rich does not boost the economy.’
