Tax-exempt foundations grew substantially in the twentieth century, both in their financial importance and in the scope of their activities. This challenging book examines the economic, cultural, and intellectual implications of tax-exempt organizations. How do various tax laws influence foundations and what types of ideas do foundations produce? How do the activities of foundations relate to the interests and intentions of their founders? Does the economic management of foundation assets serve the public good, or would such assets be better employed through the private sector? Writing Off Ideas examines these and related questions primarily by looking at specific examples as well as the overall impact of foundation practices economically and socially.
