Abstract
I evaluate the adequacy of the three models of international business ethics that have been recently proposed by Thomas Donald son, Gerard Elfstrom and Richard De George. Using the example of the conduct of the aluminum companies in Jamaica, I argue that these three models fail to address the most important of the ethical issues encountered by multinationals because they focus too narrowly on human rights issues and on utilitarian considerations. In addition I argue that these models also evidence an inadequate understanding of microeconomic theory. I end by proposing that these defects can be remedied by a model of ethics that incorporates a theory of moral rights, a utilitarian-based theory of the market, and a theory of justice.
