Richard Thaler proposes reforming charitable tax deductions in his latest Economic View column.
Consider this scenario: Having decided that charitable giving is a worthy cause, the government subsidizes charitable gifts from certain households, and for those chosen to be part of the plan, every dollar donated to a charity is increased by a specified percentage. To qualify, taxpayers must have a substantial home mortgage; the subsidy rate increases with taxable income. Low-income taxpayers receive no subsidy, but donations from qualified high-income taxpayers are subsidized by as much as 40 percent — or more.
