This article examines the compensation of top managers of nonprofits in the United States using panel data from tax returns of the organizations from 1992 to 1996. Studying managers in nonprofits is particularly interesting given the difficulty in measuring performance. The article examines many areas commonly studied in the executive pay (within for-profit firms) literature. It explores pay differences between for-profit and nonprofit firms, pay variability within and across nonprofit industries, managerial pay and performance (including organization size and fund raising) in nonprofits, the effect of government grants on managerial pay, and the relationship between boards of directors and managerial pay in nonprofits.
