Acemglu, Daron and James Robinson, Why Nations Fail: The Origins of Power, Prosperity and Poverty (2012), 529p. In recent years there has been a flurry of books that try to explain in worldhistorical terms why some of the richest regions in the world in 1500 became “underdeveloped” while Western Europe became rich. The popular answer to this question in much of the world remains that Western Imperialism impoverished many parts of the world through economic exploitation and saddled it with institutions and policies that made economic growth difficult. By contrast, mainstream development and institutional economists, mainly in developed countries, have proposed social science theories that seek to explain why some societies become rich and others do not. One of the best-known scholarly recent social science treatises on this subject is Douglas C. North, John Wallis and Barry Weingast, Violence and Social Orders: A Conceptual Framework for Interpreting Recorded Human History (2009). In quite a different vein, Jared Diamond’s biological and geographical explanations, such as Guns, Germs, and Steel (1997) and Collapse: How Societies Choose to Fail or Succeed (2005) have been a popular success. Perhaps inspired by Jared’s success, Acemglu and Robinson, economists who used sophisticated theoretical tools to explain the impact of colonial rule upon the contemporary problems of underdeveloped economies, wrote an interesting and enjoyable grand narrative aimed at the general reader but rooted in the scholarship of institutional economics. Unlike some other grand narratives that seek to explain the wealth and poverty of states that emphasize culture, geography or resources, Acemglu and Robinson focus on political institutions. The authors use concrete world historical examples, ranging from the Mayans, the Roman Empire, and the Chinese, who failed to follow up their late medieval large-scale naval expeditions in the Indian Ocean, as well as more recent examples to, argue that the right sort of political institutions are crucial for economic growth, or the lack thereof. Secondly, they insist that the institutions of underdeveloped economies are as they are because their political elites benefit from them. While many development economists and advocates tend to assume that the political elites in poor countries want to pursue policies that benefit most of their people, the authors point out that the elites of poor and failed countries are more likely to be what economists call ‘rent seekers.’ They pursue policies and maintain institutions that are in their own interests and are often contrary to the general economic development of their countries. They argue that rich and successful economies have institutions that are ‘inclusive,’ i.e. they have relatively strong and effective central governments that are open to talent, are participatory, promote education and technological innovation, are governed by a legal system that secures private property rights and the enforcement of contracts, and governs with the consent of the people in some fashion, while failed and poor societies are ‘extractive,’ designed to make only a small elite rich, are governed by a very small elite and do little to educate their people or to encourage education and technological innovation. Their key argument about economic growth appears to be that it is caused by innovation. While they concede that ‘extractive’ institutions can also deliver economic growth, it can only do so for a relatively brief period of time because it is incapable of sustaining the constant innovation that long-term growth demands. Thus, in terms of Europe’s economic success, they argue that the chief reason for Britain’s economic growth, which led to the first industrial revolution, was ultimately dependent upon its development of a strong and constitutional representative form of government as a consequence of the Revolution of 1688-89. Few modern British historians would so confidently ascribe the Industrial Revolution chiefly to its political institutions, although most cite this as one of the important factors. The book is a pleasure to read and can serve as a useful introduction to the debate about the role of political institutions and to the grand narratives that debate the ‘Rise of the West’ and the relative failure of “the rest” until recent times.
