Federal subsidies come in a variety of forms, from the overt (a check from the Treasury) to the vaguely disguised (accelerated tax depreciation) to the well-concealed (government insurance for less than the real cost). If you know your way around federal documents and are willing to work hard, you can uncover most of them. But a lot of the spadework has already been done, thanks to Subsidyscope, a joint effort of The Pew Charitable Trusts’ Economic Policy Group and the Sunlight Foundation. The new site has catalogued subsidies going to the transportation, financial services, energy and non-profit sectors, and will add health care, housing and agriculture. It even includes datasets that can be downloaded and used by researchers at no cost.
