"Sandra Suarez looks at the efforts corporations take to influence government policy. In a detailed study of the efforts of major American pharmaceutical and electronics companies to protect the tax credit applicable to their profits from investments in Puerto Rico, this rare longitudinal case study explores the firms' abilities to adapt their political strategies to a fluid and uncertain political environment. Drawing on interviews with tax lawyers, corporate lobbyists, and government officials, Suarez follows the behavior of the same group of companies over the past twenty years."--BOOK JACKET.
