    Question

    Which of the following curve shows that incessant increase in tax rates is not productive?

    A Kuznets Curve Correct Answer Incorrect Answer
    B Laffer Curve Correct Answer Incorrect Answer
    C Lorenz Curve Correct Answer Incorrect Answer
    D Phillips Curve Correct Answer Incorrect Answer

    Solution

    • The Laffer curve shows the relationship between tax rates and tax revenue collected by governments.
    • The curve suggests that, as taxes increase from low levels, tax revenue collected by the government also increases. It also shows that tax rates increasing after a certain point (T*) would cause people not to work as hard or not at all, thereby reducing tax revenue.
    • Eventually, if tax rates reached 100% (the far right of the curve), then all people would choose not to work because everything they earned would go to the government.
