Mr. Muzinich, a 39-year-old newcomer to Washington, has emerged as a central player in the Trump administration’s tax overhaul effort. The former investment banker and hedge fund manager is the Treasury point man on taxes, accompanying Mr. Mnuchin into “Big Six” meetings with top Republican lawmakers drafting the tax plan and laying out the administration’s positions on which taxes and deductions to cut or preserve.
.. He fits the mold of Mr. Trump’s top economic advisers, Mr. Mnuchin and Gary D. Cohn, the director of the National Economic Council, both of whom made a career on Wall Street. While not a Goldman Sachs alumnus, as they are, he brings an extensive background from the world of finance, having been a banker at Morgan Stanley and the president of Muzinich & Co., an international investment firm founded by his father.
.. His Wall Street brashness sometimes shines through when he gets into deal-making mode.
.. Mr. Muzinich, who holds an M.B.A. from Harvard and a law degree from Yale
.. In a 2007 Op-Ed article in The New York Times, Mr. Muzinich and a co-author, Eric Werker, called on Congress to offer tax credits to companies that build factories in developing countries and to offset the lost revenue with reductions in foreign aid.
.. “I think that he is pragmatic,” said Glenn Hubbard, the dean of Columbia Business School, where Mr. Muzinich taught before joining the Treasury Department. “He’s looking for good policy solutions, not policy positions.”
.. Some economists have scoffed at Mr. Mnuchin’s promises that tax cuts would more than pay for themselves because of the robust economic growth he says they will create. The department came under fire for removing from its web site an economic study that contradicted the secretary’s analysis of the benefits of corporate tax cuts.
