Corporations have been investing in academia to an extent that could be classified as a corporate takeover of universities. Intra‐university critics see this as an ethical problem, because of the degree of business control over university policies and decisions which accompanies the funding. University critics rarely suggest that the corporate funding be given up, returned, or even limited. What they protest against is corporate control, which they see as threatening university autonomy, and as inimical to the public good. Multi‐university conferences (...) have been held focusing on this problem, and the most serious solution proposed thus far is to construct a relevant code of ethics regulating and limiting corporate involvement, through standards and guidelines which corporations will then have to subscribe to, in order to fund universities. However, there is a conflict of interest here. Universities have a public trust and a fiduciary duty not to compromise education. This implies a covenant not to cede power to outside interests, not to use university resources, or faculty and students, as a means to an educationally irrelevant end. Universities cannot sell out. However, it seems equally dishonest not to offer their students a well‐funded first‐rate, quality education in applied fields with current skills, maximum research opportunity, and the corporate ties that would allow them to obtain jobs. We examine three cases showing errors made by universities in ceding control to corporate investment, and draw some policy conclusions. (shrink)
