Question: Background: The Laffer curve depicts the amount of government revenue as a function of the rate of taxation. It shows that for a tax rate above a certain critical rate, government revenue starts decreasing as the tax rate rises, as a consequence of a decline in labour supply. This theory supports that, if the tax rate is above that critical point, a decrease in the tax rate should imply a rise in labour supply that in turn would lead to an increase in government revenue.
