“…To date, the abstract economy framework has mainly been used to establish equilibrium existence theorems for economies having various non‐Arrow–Debreu features. Such features include: interdependent preferences, price‐dependent preferences, and preferences which may be both non‐transitive and non‐complete (Shafer & Sonnenschein, 1975; Li, 2018); externalities and public goods (Shafer & Sonnenschein, 1976; Florenzano, 2009); private information and a countable set of actions (Patriche, 2013); and economies with unbounded attainable sets in which consumers may have non‐complete non‐transitive preferences (Ounaies et al . , 2019), to name a few.…”
