One potential result of the Laffer curve is that increasing tax rates beyond a certain point will become counterproductive for raising further tax revenue.
The Laffer curve is typically represented as a graph that starts at 0% tax with zero revenue, rises to a maximum rate of revenue at an intermediate rate of taxation, and then falls again to zero revenue at a 100% tax rate.
The Laffer curve assumes that no tax revenue is raised at the extreme tax rates of 0% and 100%, and that there is a rate between 0% and 100% that maximizes government taxation revenue.
