Total economic surplus would be $ $100000$ per day without a minimum wage, and would be reduced by $ $4000$ per day with a minimum wage at $$12$ per hour. Calculate the amounts by which employer surplus and worker surplus change as a result of the minimum wage. Employer surplus would be reduced by $ per day. Worker surplus would be increased by $ per day. How much would it cost the government each day to provide an earned$-$income tax credit under which workers as a group receive the same economic surplus as they do under the $$12$ per hour minimum wage? $($Assume for simplicity that the earned$-$income tax credit has no effect on labor supply.$)$ The tax credit would cost the government $ per day.
