STEPHEN J. ENTIN, a proponent in Washington of the supply-side theory of taxation that favors eliminating most taxes on capital, said last year that denying the 15 percent tax rate to some investors poisons the tax cut. Mr. Entin, the president of the Institute for Research on the Economics of Taxation, said in an interview last month that one should be a little more ticked off at the world if one is in the phase-out range and, like Mr. Carreiro, pay higher tax rates on dividends. In a report, Mr. Entin wrote that investors are still better off under the 2003 tax rate cuts even if they are in the phase-out range.
