“…Fudenberg and Levine (2019) model research designs, such as RD or difference-in-differences, in a model where information feedback affects effort that endogenously determines treatment. Other work, somewhat further afield, uses theory to think about how to optimally design treatments to maximize learning (Banerjee, Chassang, and Snowberg 2017; Chassang, Padró i Miquel and Snowberg 2012) or to question the normative or positive interpretation of well-identified empirical findings (Ashworth and Bueno de Mesquita 2014; Ashworth, Bueno de Mesquita, and Friedenberg 2018; Fowler 2018; Izzo, Dewan, and Wolton 2018; Prato and Wolton 2018; Sun and Tyson 2019; Wolton 2019).…”
