Consider the two negative charges shown. Two negative charges of magnitude minus Q are positioned on the X axis in an X Y coordinate system. The charges are equidistant from the Y axis and located to either side of it. Point P is on the Y axis and above the X axis, forming the apex of an isoceles tr...

1. Calculate the CS, PS, the externality cost, and overall surplus in the absence of the tax. Then calculate these again under the tax, taking into account the tax revenue raised. Calculating the various triangles, we get the results as outlines in the table below. When calculating the external cost...
