Corporations, like individuals, face an alternative minimum tax (AMT). (See the discussion in Chapter 17.) In 2001, the House of Representatives passed a bill abolishing the corporate AMT retroactively. This meant that rebate checks would be sent to corporations for past payments of the AMT. The intention of the bill was to stimulate investment. Use the neoclassical theory of investment to assess whether a retroactive tax cut can be an effective way to stimulare investment. (Hint: How does such a tax cut affect the user cost of capital?)
