Does brick size matter? Albert G. Keller on another QWERTY story
发现耶鲁社会学家凯勒在砖税案例中提出了与凡勃伦类似的路径依赖论点，比凡勃伦更早，对理解制度惯性有参考价值。
In his seminal “Clio and the Economics of Qwerty”, Paul David indicates Thorstein Veblen’s famous discussion of the British system of coal rail haulage as an intellectual antecedent to the idea of lock in. This note documents how Albert G. Keller, a Yale sociologist contemporary of Veblen, had presented a similar argument in connection to the establishment of a brick tax in England and its effects on the size of bricks. Like Veblen, Keller used this illustration to emphasize the inertia exercised by certain institutional conditions.
