One measure adopted by America for post-war recovery was : (i) Mass production; it became a feature of industrial production in US. An example is Henry Ford, the car manufacturer. He adopted ‘assembly line’ method for faster and cheaper production. Car production increased from 2 million in 1919 to more than five million units in 1929. (ii) Similarly, there was boom in production of refrigerators, washing machines, all purchased through a ‘‘hire purchase’ system, credit repaid in weekly or monthly instalments. (iii) There were large investments in housing and household goods which created a cycle of higher employment and incomes, rising consumption demand, more investment. (iv) The US resumed exporting capital to the world in 1923. US exports and imports boosted European recovery and world trade and income growth over the next six years.
