What is the cost of not having economic history at MIT? It can be seen in Acemoglu and Robinson, Why Nations Fail (2012). This is a deservedly successful popular book, making a simple and strong point that the authors made originally at the professional level over a decade before (Acemoglu, Johnson and Robinson, 2001). They assert that countries can be “ruled by a narrow elite that have [sic] organized society for their own benefit at the expense of the vast mass of people” or can have “a revolution that transformed the politics and thus the economics of the nation … to expand their economic opportunities (Acemoglu and Robinson, 2012, pp. 3-4).”
The book is not however good economic history. It is an example of Whig history in which good policies make for progress and bad policies preclude it. Only transitions from bad to good are considered in this colorful but still monotonic story. The clear implication is that if countries can copy the policies of English-speaking countries, they will prosper. No consideration is given to Britain’s economic problems over the past half-century or of Australia’s relative decline for a century.
Also, to be honest, one of the reasons I am into development (and the politics around it) is because of my fascination with economic history. I wish more development practitioners and theorists alike cared a little bit more about economic history. At the very least, looking at how things really actually worked out in the past serves to temper the urge to completely fall for the latest fad within the development industry.
