However, this study tried to pull out and isolate that one factor and quantify the impact of that one factor on GDP. It found a positive correlation, which, frankly, I find a bit surprising, but it calls into question this assumption that, if you raise capital gains taxes, it's going to negatively impact the gross domestic product.
I can read you the summary of the study and what they're actually finding.

This brief provides a new analysis of the macroeconomic effects of raising taxes on dividend income and capital gains. Increasing dividend income and capital gains taxes from 20% to 39.6% for households earning over $1 million would raise government revenue by about 5% and GDP by about 1% in the long term.
It goes on to say at the end:
