A Crash Is a Crash
He pointed out that the Dow Jones Index was around 300 just before the October 29, 1929, crash (301 on October 25--it had been higher earlier in the month, reflecting euphoric expectations). On October 29, the Dow Jones Industrial Average fell 30 points. It fluctuated and then gradually regained strength, reaching 293 on April 12, 1930.
In other words, Wall Street initially recovered from the crash.
Unfortunately, the Depression lay ahead.
Although the Dow Jones average stayed in the 200s for nearly six months in 1930, in October it fell below 200 and declined to a low of 43 in July 1932. The index did not reach 300 again until 1954.
So what caused the Depression? Gwartney and others have related the impacts of the Smoot-Hawley tariff (enacted in 1930), the Hoover tax increases (adopted in 1932), and, of course, the shrinkage of the money supply, famously discussed by Milton Friedman and Anna Schwartz.
And then, when Roosevelt became president, there were the famed destruction of hogs and baby chicks to raise farm prices, the implementation of costly public works projects, and numerous other economic distortions. (For a soft-pedaled overview, see Tyler Cowen’s article today.) There is much to blame the Depression on. But don't blame the stock market crash.
