Yes, thanks indeed Meaglyn.
I've read the paper and have thought about it off and on for the past few days. I've decided that I disagree with the author's conclusions. While it's an interesting idea that centralized political stability encouraged the adoption of the longbow and the converse, fear of rebellion quashed the idea --- I just don't buy it.
The author did not examine any other nations besides England, Scotland, Wales, France, and the Netherlands/Belgium. What about the Holy Roman Empire? Norway, Sweden, or Denmark? And what about Japan which did adopt the longbow but not Korea, China, or anywhere else? Not to mention the Americas and Africa.
I think that for a dissertation on economic models, 1) the author should have reviewed far more nations and 2) developed the model after reviewing the data rather than picking a model and seeking data (failing that, rhetoric) to support it.
In short, interesting idea poorly researched.
