At a book launch Nov. 11 for Linsey McGoey’s No Such Thing as a Free Gift,  BC Law School Professor Ray Madoff will engage in conversation with the author, as well as Alicia Yamin of Harvard University and Nicole Aschoff  Jacobin magazine. The book launch will be held from 6 to 8 p.m. at the Harvard Coop on Mass. Ave. in Cambridge. The charitable sector is one of the fastest-growing industries in the global economy.  As large charitable organizations replace governments as the providers of social welfare, their largesse becomes suspect. In her new, McGoey puts this new golden age of philanthropy under the microscope—paying particular attention to the Bill and Melinda Gates Foundation.
