(R & G) In an economy, the supply curve of labor, S, is given by
S = - 100 + 200 Wn
where Wn is the after-tax wage rate. Assume that the
before-tax wage rate is fixed at 10.
(a) Write a formula for tax revenues as a function of the tax rate,
and sketch the function in a diagram with the tax rate on the
horizontal axis and tax revenues on the vertical axis. (wn = (1 -
t)10 where t is the tax rate.) Suppose that the government
currently
imposes a tax rate of 70 percent. What advice would you give
it?
(b) At what tax rate are tax revenues maximized in this
economy?
