“We know quite a bit about the impact of this kind of tax,” said Milligan. “You hear some people say it will deter business investment , this will deter entrepreneurship. And the evidence on that is pretty strong that that’s not the case.”
Milligan said that's because at the very, very high end of income distribution, most of the income is earned income.
"These aren’t entrepreneurs and investors. These are people who are working for a living. They are very well-compensated people working for a living, but it just makes it a very different set of people than if these were all investors with a big pot of money wondering where they will invest it."
But Milligan said he doesn’t believe top executives won't work as hard or leave the province because they’re earning a couple percentage points less.
