6. Who should pay the tax? The following graph gives the labor market for laboratory aides in the imaginary country of Paideia. The equilibrium hourly wage is $10, and the equilibrium number of laboratory aides is 250. Suppose the federal government of Paidela has decided to institute an hourly payroll tax of $4 on laboratory aldes and wants to determine whether the tax should be levied on the workers, the employers, or both (in such a way that half the tax is collected from each party). Use the graph input tool to evaluate these three proposals. Entering a number into the Tax Levied on Employers field (initially set at zero dollars per hour) shifts the demand curve down by the amount you enter, and entering a number into the Tax Levied on Workers field (initially set at zer dollars per hour) shifts the supply curve up by the amount you enter. To determine the before-tax wage for each tax proposal, adjust the amount in the Wage field until the quantity of labor supplied equals the…

A rectangle is a four-sided figure that has two sets of parallel sides, so that we have two sides of one length and two sides of another length; a square is just a special case of a rectangle in which all four sides are the same length. Therefore, the procedure for calculating area is the same no matter whether we are dealing with a rectangle or a square. The area of a rectangle is calculated as follows: Area = base x height = b × h In this formula, the base is the width of the rectangle and the height is simply how tall the rectangle Is. For example, if we have a rectangle that is 20 centimeters wide and 10 centimeters tall, its area can be calculated as follows: Area = 20 cm x 10 cm = 200 cm² Note the superscript '2' In our answer; this is because we have multiplied centimeters by centimeters. In economics, we are more likely to be dealing with quantities bought or sold and prices, so don't worry about it too much for our discussion. The area of a triangle A triangle is really just a…
