“…Rather than focusing on the aforementioned macroeconomic-based non-linear e¤ects, our paper focuses on the non-linear distortion-based e¤ects of tax changes on output. 4 In a recent theoretical paper, Jaimovich and Rebelo (2017) show that the long-run output e¤ect of tax changes is small at low initial levels of taxation but exponentially larger when initial tax levels are high. This result is naturally related to a well-established public …nance literature (e.g., Harberger, 1964a and1964b;Browning, 1975;Feldstein, 1995) arguing that the excess burden of taxation, or deadweight loss, associated with taxation is small at low tax taxes, increases with higher tax rates, until, eventually, "a tax [is] imposed at so high rate that it eliminates the tax activity" (Hines, 2007, page 4 As we will discuss later in Sections 6.3 and 7, macroeconomic-based non-linear e¤ects are not behind the non-linear e¤ects associated with distortion-based arguments.…”
