You are the director of a Washington, D.C., think tank focusing on tax and economic policy issues. You were recently (and informally) contacted by staff of the congressional joint committee on taxation to weigh in on a number of issues currently under consideration by the committee. In particular, the committee asked you to reflect upon the following proposed changes and/or issues. 

(I) The committee has proposed to phasing out the PAD for domestic corporations. 

(II) The committee has considered separating the gift and estate tax systems from one unified system, to two completely independent, separate systems. 

(III) The committee is intrigued by the idea of eliminating the double taxation of corporate earnings. The members are, however, unsure which level of taxation should be eliminated. The committee would like for you to summarize your conclusions regarding the potential effects- both good and bad- of these potential changes. In formulating your answer, please discuss all of the possible tax and economic implications that you see arising from these transactions on all taxpayers.
