This is the very important project worked by two scholars of great erudition. Many people may hesitate to add any comments on this well prepared research project. As the project workers are pointing that "[t]his project sits at the intersection of economics, politics, law, and history," let me add a comment from an economist who mainly work on international trade theory.
The project workers are more interested in the internal legal and political aspects, but the international relations in economic domains affect the domestic policy thinking tremendously and economic performance. Without a deep analysis on the economic conditions that the developing countries are confined and what kind of possibility they have, the project would not be a sufficient examination.
The trouble with economics is the dominance of neoclassical economics backed by neoliberal economic policy thought. This mode of thinking is enforced upon developing countries through IMF and World Bank and others. On the other hand, anti-mainstream economic theories in developing countries are/were deeply influenced by Marxian economics and it had/has a strong tendency to emphasize an exploitation of developing countries by developed countries. A typical argument is the unequal exchange theory of A. Emmanuel and of the dependency theory.
We need a plausible theory on the economic development of developing countries. Unfortunately, there was a strong schism between growth theory and development economics in the past. Now this schism seems to be bridged a bit but it is rather an appearance caused by the intellectual dominance of the growth theory. The latter has serious problems as a theory of economic growth and development. In this regard, let me cite three survey papers:

Mine is a general criticism on the existing growth theories. Two others treat questions which were not treated in my and Kurz and Salvadori's survey papers.
In order to understand and estimate rightly the condition that the developing countries are confined, the theory of international trade is important. In this regard, please read my paper below. At the end of this paper, I mentioned on the relationships between this general theory and development economics and international political economy. The main lesson of this paper is this: Whatever happens in the institutions and political system, it is through the mediation of production techniques that the income per capita of a country is determined. Of course, institutions and legal and political systems give great influences on the development of production techniques.

Let me also inform you that I have posed three questions below on the relations between international political economy and trade theory. I have also posted several answers to the Julio César Cepeda Ladino's question.
