capacity" in the form of more pumping stations than they would otherwise need if they
were operating under conditions of perfect competition. However, can you think of any

knows will rarely if ever be fully utilized at any one time? Can you explain the
economic logic of this "apparent" wastefulness?

revenue from personal taxes. As the rate is raised the government collects more revenue
but at a decreasing rate. Suppose furthermore that at some tax rate of let's say 30% the

in tax revenue collected. From this information and that contained in the table below
graph the relationship between the tax rate and tax revenue with the tax rate on the
horizontal axis and tax revenue on the vertical axis.
