Because of the influential role that the U.S. stock market plays in international finance, a New York University study in late 2014 interprets that in the short run, stocks that affect the willingness to bear risk independently of macroeconomic fundamentals explain most of the variation in the U.S. stock market.

Productivity shocks, however, play a small role in historical stock market fluctuations at all horizons in the U.S. stock market. The U.S. finance industry comprised only 10% of total non-farm business profits in 1947, but it grew to 50% by 2010. Over the same period, finance industry income as a proportion of GDP rose from 2.5% to 7.5%, and the finance industry's proportion of all corporate income rose from 10% to 20%. The mean earnings per employee hour in finance relative to all other sectors has closely mirrored the share of total U.S. income earned by the top 1% income earners since 1930. The mean salary in New York City's finance industry rose from $80,000 in 1981 to $360,000 in 2011, while average New York City salaries rose from $40,000 to $70,000. In 1988, there were about 12,500 U.S. banks with less than $300million in deposits, and about 900 with more deposits, but by 2012, there were only 4,200 banks with less than $300million in deposits in the U.S., and over 1,800 with more.
