AGRICULTURAL PROTECTION: AN OBSERVATION AND WARNING

Agricultural protection, especially of the nontariff type, is on the increase despite some recent appearances to the contrary. The forces behind this trend are heavily economic and immediate, relating principally to domestic farm programs. But there are other forces: self-sufficiency policies, social and cultural factors, and national security matters, which are also used to support protection in the political arena and over the long run. It is imperative that the leading industrial countries, with the assistance of leading developing countries, negotiate trade arrangements and agricultural adjustment policies that take advantage of the proven principles of comparative advantage. The alternative might be a trade breakdown similar to that of the 1930s.Agricultural and Food Policy,

Three Lenses on the Multinational Enterprise: Politics, Corruption and Corporate Social Responsibility.

Scholars who study multinational enterprises (MNEs) recognize the complex relationship between international business and society. However, compared to other international business topics, research on politics, corruption and corporate social responsibility (CSR) -- three 'lenses' on the MNE -- remains somewhat embryonic, with critical unresolved issues regarding frameworks, measurement, methods and theory. This creates rich opportunities for integration and extension of disciplinary perspectives, which we explore in this article. Building on the three lenses framework, we identify common concepts and tools, outline an agenda for additional theoretical and empirical research, and review the papers in a Focused Issue of the Journal of International Business Studies.
