Many people, this groupfor instance, argue that foreign aid often fails because of the inability of donor countries to export their institutions to developing countries. The new institutions simply do not stick to the local circumstances. Daron Acemoglu, Davide Cantoni, Simon Johnson, and James A. Robinson disagree. They find that Napoleon's expansion and the associated instututional reforms did stick and improved economic performance over the long-run. Here is the abstract (paper available here):
The French Revolution of 1789 had a momentous impact on neighboring countries. The French Revolutionary armies during the 1790s and later under Napoleon invaded and controlled large parts of Europe. Together with invasion came various radical institutional changes. French invasion removed the legal and economic barriers that had protected the nobility, clergy, guilds, and urban oligarchies and established the principle of equality before the law. The evidence suggests that areas that were occupied by the French and that underwent radical institutional reform experienced more rapid urbanization and economic growth, especially after 1850. There is no evidence of a negative effect of French invasion. Our interpretation is that the Revolution destroyed (the institutional underpinnings of) the power of oligarchies and elites opposed to economic change; combined with the arrival of new economic and industrial opportunities in the second half of the 19th century, this helped pave the way for future economic growth. The evidence does not provide any support for several other views, most notably, that evolved institutions are inherently superior to those “designed”; that institutions must be “appropriate” and cannot be “transplanted”; and that the civil code and other French institutions have adverse economic effects. They seem to argue that "big" reforms work and marginal changes do not. If true, then the current business model for foreign aid needs some major reworking.
