Jared Bernstein, New York Times Opinion, July 22,2015: The Case for a Tax on Financial Transactions
Bernie Sanders made the case for a financial transactional tax in 2015. Jared Bernstein was largely supportive, but said details need to be worked out.
"Senator Bernie Sanders of Vermont, who is seeking the Democratic nomination for president, has done just that, by proposing a financial transaction tax: a small excise tax, typically a few hundredths of a percent, on trades of stocks, bonds, derivatives and other securities. An itty-bitty, one-basis-point transaction tax (a basis point is one-hundredth of a percentage point, or 0.01 percent) would raise $185 billion over 10 years, according to new estimates by the nonpartisan Tax Policy Center."
He discusses it more in his NYT opinion article above. Seems like one good source of revenue to me.
