The Importance of Douglass North

 

I just listened to an episode Econ Roots, in which Mike Munger was interviewed about the importance of Douglass C. North. Like myself, Munger went to Washington University and worked with North. His answer to why North was important was that “he had a view of economic history that took time seriously.” He notes, for example, that North would ask about where preferences came from rather than taking them as given.

It is a great podcast episode, but my personal answer to the question would be slightly different because I had recognized the importance of explain changes in institution over time before I read North. As an undergraduate at the The Evergreen State College the two books that had the biggest impact on me were Samuelson’s Economics and Thorstein Veblen’s Theory of the Leisure Class.

The neo-classical economics of Samuelson immediately made sense to me. I found the use of models to analyze individuals maximizing subject to constraints and interacting with other people doing the same to be an incredibly powerful tool.

Then I read Veblen. Veblen argued that economic theory was fine as far as it went, but it didn’t go far enough. In his first book, The Theory of The Leisure Class (1899), he explained that, "The institutions are, in substance, prevalent habits of thought with respect to particular relations and to particular functions of the individual and of the community: and the scheme of life, which is made up of the aggregate of institutions in force at a given point in the development of any society, may on the psychological side be broadly characterized as a prevalent spiritual attitude, or theory of life." (Veblen 1912, 190) Thus, “the evolution of society is substantially a process of mental adaption on the part of individuals under the stress of circumstances which will no longer tolerate habits of thought formed under and conforming to circumstances in the past." (Veblen 1912, 192) To Veblen this process of cultural change should be the central concern of economists: He argued that both the preferences and constraints that economic theory takes as given change over time and answering the biggest questions in economics requires understanding how they change over time.

So, I was persuaded of both the utility of economic theory and the need to explain how the things that influences those choices, including preferences, change over time.

I know that Doug read Veblen when he was younger, but I don’t think he was influenced by him, at least consciously. I don’t know if he ever read Samuelson. Yet what North provided me was a link between institutional change and economic theory. And the link ran in both directions. He provided an approach that made it possible to talk about the impact of institutions on market performance and to use economic theory to try to understand how institutions changed. The idea of transaction costs provided a means to connect different institutional arrangements to the performance of markets. Transactions costs create a wedge between buyers and sellers. The more resources you must use trying to enforce agreements or protect your property the less mutually beneficial trades will exist. Effective institutions can lower the cost of transactions, encouraging trade, investment, and innovation.  Economic models can also be used to try to explain differences in institutions and how they change over time. The first thing I read by North was a “Framework for Analyzing the State in Economic History,” followed immediately by Structure and Change. In both he used a simple model of a wealth maximizing ruler to explain institutions that do not maximize economic output. He asked why wealth maximizing ruler might not create rules that maximized output for the country, creating the largest possible pool of wealth to extract revenue from. The answer in this model was that the ruler faced a transaction cost constraint and a competition constraint. The wealth maximizing institutions might entail higher costs of collecting taxes than institutions that lead to lower levels of output. For instance, selling a monopoly might be an easy way to raise revenue but not one that is likely to maximize output. This is the transaction cost constraint. The competition constraint arises from the fact that wealth maximizing institutions might be ones that enhance the power of potential competitors to the ruler. For instance, international trade might increase output but also increase the wealth and power of people who present a potential threat to the ruler.

For me, Doug’s work meant that I didn’t have to choose between Samuelson and Veblen.
