“…Benefit-based reasoning was a prominent, and at times leading, approach among tax theorists in the early twentieth century (Seligman, 1908;Musgrave, 1959). 15 However, it has been largely ignored by the modern optimal taxation literature, which instead focuses exclusively on efficiency (Weinzierl, 2018;Scherf and Weinzierl, 2020). Besides benefit-based taxation, a growing body of work is trying to incorporate other normative considerations into tax policy design (Mankiw and Weinzierl, 2010;Weinzierl, 2014;Saez and Stantcheva, 2016;Lockwood and Weinzierl, 2016).…”
