Choice by sequential procedures

► We provide a clean and sharp taxonomy of three recent and influential models of nonstandard choice behavior. ► The status quo bias theory of Masatlioglu and Ok (2005, 2010). ► The notion of rationalizability by game trees due to Xu and Zhou (2007). ► Manzini and Mariottiʼs (2007) sequential rationalizability model. ► We think our results are crucial for a good understanding of the literature, and for its proper development in the future.
