We’ve been asked a few times to analyse the revenue impact of imposing 20% VAT on private schools. We’ve declined, because it’s a complicated piece of work which probably requires a large team with economic and educational expertise – the actual tax element is relatively small and straightforward.<\/p>\n\n\n\n

UPDATE 11 JULY: this article is now out of date – the IFS has published a serious piece of research on the subject<\/a><\/strong><\/p>\n\n\n\n

A think tank, EDSK, published a paper<\/a> today looking at this point. Unfortunately, they have not actually undertaken their own analysis, just made some simple calculations based upon previously published figures. The problem is that those figures are, in our view are highly questionable, and perhaps useless. Hence this is a case of “garbage in, garbage out”, and we would caution against taking any figures in the report seriously.<\/p>\n\n\n\n

For the same reason, we would caution against taking any<\/strong> of the various figures floating around seriously, unless and until a full analysis is undertaken.<\/p>\n\n\n\n

Credit to EDSK – their paper readily admits its own flaws, right at the end – key effects were not taken into account. But these are significant issues which can’t just be ignored:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n

The questionable figures<\/h2>\n\n\n

Any estimate of the revenue impact rests upon a key question: what percentage of children would leave private schools if VAT was imposed? The paper uses two previous estimates: 5% and 25%. It treats them as higher and lower upper bound estimates:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

But the 5% and 25% figures shouldn’t be treated so seriously.<\/p>\n\n\n\n

The 5% figure comes from the 2019 Labour Party manifesto. It took a price elasticity estimate from an IFS analysis<\/a> which looked at the impact of changes in school fees on the rate of children going to private schools. Then the Labour Party simply applied the elasticity to a 20% price increase.<\/p>\n\n\n\n

This was not a good approach. The IFS paper looks like a serious piece of work, but it looked at much smaller prices than 20%, and occurring over a long period. So it is likely incorrect to assume the IFS elasticity holds for an immediate 20% VAT increase, and this error surely means that the Labour Party figure was understated. On the other hand, the IFS found price sensitivity only at entry points – ages 7, 11, 13, and so it’s not correct to simply apply this elasticity to all private school pupils. That would tend to over-state the effect. Taken together, these effects render the 5% estimate of limited and perhaps no use.<\/p>\n\n\n\n

The 25% figure comes from a slightly mysterious survey <\/a>of heads and parents at 21 schools by a consultancy engaged by the Independent Schools Council. The mystery being that details of the methodology are scant and, even in principle, surveying parents and headteachers in a mere 21 schools seems unlikely to reveal much about what would actually happen across the country if school fees increased. The likelihood of conscious and unconscious bias is obvious:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Exactly how the calculations were carried out is not revealed in the paper, but there is no evidence of any statistical analysis, and results are presented to two decimal points without any discussion of statistical error (or indeed even a single mention of any statistical tools).<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Hence we would regard the 25% figure as meaningless. We don’t think EDSK should have taken them as upper\/lower bound estimates, or even used them at all.<\/p>\n\n\n

How would an actual analysis be undertaken?<\/h2>\n\n\n

Having spoken to a variety of economic and education policy experts, we believe a proper analysis would look something like this:<\/p>\n\n\n\n
