Teper, Jeffrey. "Evaluating the Cost of Socially Responsible Investing," in Kinder, Peter, Steven Lydenberg, and Amy Domini, ed., The Social Investment Almanac, New York: Henry Holt, 1992.

Argues that social investors must incur a cost, estimated at 1% per annum for equity accounts. Compares unrestricted accounts with sin-free accounts, and finds that, from December 1984 - September 1990 the sin-free accounts incurred a risk-adjusted cost of 1.1%.
