Charitable giving: The IRS and Richard Thaler
The USA often gets a bad rep for not doing enough to help alleviate poverty in the developing world. While it’s true the government spending for foreign aid is much lower than European, and particularly Scandinavian, countries, as I’ve argued before, private citizens in the US are more generous than most others.
I just wanted to write a very short piece analysing the private incentives for donating to charity. It’s something that randomly occurred to me on the train last week.
In the US, the IRS says:
"You may deduct charitable contributions of money or property made to qualified organizations if you itemize your deductions." (IRS Publication 78)
For cash or property donations, as long as you keep itemised written evidence, you can deduct cash contributions in full up to 50% of your adjusted gross income and property to 20%. In other words, donating $1 in cash saves a taxpayer 50 cents in income taxes.
President Obama is proposing caps on the value of the tax break for itemised deductions, including donations to charity, to 28 percent for families making more than $250,000. The argument against this is that it will haemorrhage donations from wealthy families. But this is outside the scope of this blog post.
Individuals paying tax in the UK and US often find that the US tax rules invalidate UK tax breaks on charitable giving. Again, although I’m comparing the US and UK approaches to economic incentives for charitable giving, this is outside the scope.
In the UK, Gift Aid enables the donor to immediately benefit from a tax break. If I give £1 to a charity, including Gift Aid, it will receive £1.28.
Contrast the US and UK approaches:
US: Refund given ex-post often months later; transaction cost involved with claiming this money back; when you do receive the money, it’s like a nice present from the IRS
UK: Far simpler system; ex-ante realisation of the additional benefit provided to charity; flat rate of Gift Aid which is easy to understand; no additional personal monetary benefit of giving
These two contrasting systems have remarkably different economic incentives structures, at least in theory. Using Richard Thaler’s prospect theory terminology, both US and UK donors feel the pain of donation simultaneously with the pleasure of having donated. Americans additionally experiences the small pain of having to record documentary proof, but then experience the big pleasure of a rebate a few months later after they have gotten used to operating with a tighter budget constraint. In the UK case, donating is a more passive affair because of the lack of these latter two effects.
The implication of prospect theory is that utility might be reference-based i.e. you consider not only the value you receive from a transaction but the value others receive. The utility function this creates is asymmetric and implies shows that people feel losses more acutely than gains. More relevantly for this example, it also shows that people prefer disaggregating gains (having two gains is better than having one gain of equal value).
Without having done empirical research into this, the theory suggests the US approach might be better at encouraging people to donate.
