Effectiveness Lag | The time it takes for a fiscal measure to affect the economy |
Marginal Income Tax Rate | The change in a person's payment divided by the change in his or her taxable income |
Laffer Curve | The curve, named after Arthur Laffer, that shows the relationship between tax rates and tax revenues. According to the Laffer curve, as tax rates rise from zero, tax revenues rise, reach a maximum at some point, and then fall with further increases |
Tax Base | In terms of income taxes, the total amount of taxable income. Tax revenue=Tax Base x (average) Tax Rate |
