The Model T

We ask (1) why the United States adopted the car more quickly than other countries before 1929, and (2) why in the United States the car changed from a luxury to a mass-market good between 1909 and 1919. The answer is in part the success of the Model T in the United States. Mass production of the Model T began in 1913; by 1917, more than 40 percent of U.S. cars were Model Ts. Tariffs and difficulties producing outside Detroit made the U.S. success of the Model T difficult to replicate abroad.
