Key Concepts

Laffer Curve

The Laffer Curve is a graphical representation that shows the relationship between tax rates and the amount of tax revenue generated by the government. It illustrates that there is an optimal tax rate which maximizes revenue; beyond this point, higher taxes can reduce economic activity, thereby decreasing total revenue.

Tax Revenue Maximization

Tax revenue maximization refers to the process of identifying the income-maximizing tax rate. This concept is rooted in the understanding that tax rates can have counterintuitive effects on revenue due to economic behaviors such as labor participation and investment decisions, which are central to the insights provided by the Laffer Curve.

00:01 Hi, everyone.

00:01 Today we will be solving problem five from chapter 8, which discusses the laffer curve.

00:08 So i thought it would be useful to start off by drawing the laffer curve for you guys.

00:13 So simple set of axes, and then we're going to put tax revenue on the y -axis.

00:21 So tr is going to represent tax revenue.

00:24 And then on the x -axis, we're going to put tax size, which is going to be represented by t -s.

00:29 Sorry, tr represents tax revenue, ts represents tax size.

00:34 Hopefully that's clear.

00:36 And now we're going to draw the laffer curve, which basically resembles an upside -down -you.

00:42 And we're going to basically just mark, my graph isn't perfect, we're going to mark the turning point at which the laffer curve goes from upward sloping to downward sloping.

00:54 We're going to break up the laffer curve into two sections, section one and section two.

01:01 So now we're going to explain the two different sections of the locker curve.

01:06 So section one represents the following case.

01:10 Basically, when a government decides to start increasing the tax on a good, what's going to happen is that the tax revenue is going to increase with the size of the tax.

01:21 It's going to have a positive relationship.

01:23 So we're just going to write this out.

01:26 This is for part one of the curve.

01:28 As the tax size is increased by the government, use the up arrow to demonstrate that, the tax revenue will also rise and will rise in proportion to the tax size.

01:45 And this should make sense because as the tax size increases, the government is going to be taking in more in tax and will have a higher tax revenue.

01:54 But then something interesting happens.

01:57 As the size of a tax increases, it's going to make the good more expensive.

02:02 Expensive, which is going to make it less successful for a lot of buyers.

02:07 And some buyers, if they see that the tax has become so big, we'll leave the market...
