In this discussion, we are going to analyze the role and scale of the stock market across countries and over time. 
This graph shows the market capitalization as a percent of GDP for the US(https://fred.stlouisfed.org/graph/?g=qQTG). This graph shows the same thing for China(https://fred.stlouisfed.org/graph/?g=r7of). Please comments on the differences between these two economies. I expect you to use at least two references. Please feel free to compare other countries if you prefer.
