This course presents an introduction to the fundamentals of international economic law, providing students with a broad understanding of the field. It delves into topics such as: the development of the Bretton Woods system and the struggles between capital-exporting and capital-importing states over the course of the last century; the history, operation, and continued relevance of the International Monetary Fund (IMF); the challenges of development and the work of the World Bank; the establishment of the World Trade Organization (WTO), the basic rules that its covered agreements establish, and its dispute settlement system; the growing level regional economic integration through Free Trade Agreements (FTAs) and the political impacts of this trend; and the explosive rise of bilateral investment treaties (BITs) and the counter-movements of resistance and calls for reform. Throughout the course special attention will be paid to challenges and critiques of international economic law, and students will be encouraged to think further and deeper with respect to the real-world application of the principles they learn. The impact of the economic law on state actors in times of crisis (such as the economic crisis of 2008 or COVID-19), tensions between economic and non-economic policy, the choice between regional and global mechanisms, and Colombia’s role in the global economy will all be given special consideration.
