This paper studies the conditions under which the basic results of the revealed preference theory can be established on the domain of choice problems which include non-convex feasible sets; the exercise is closely related to the works of Peters and Wakker (1991) and Bossert (1994). We show that...

In this paper, we consider the problem that a benevolent designer wants to provide a non-excludable public good with a fixed cost to agents with privately known valuations. Adopting utilitarian's point of view, the designer maximizes the ex-ante total utility of all agents. The impossibility...

Two-dimensional (2D) transition metal oxides (TMOs) are widely applied in various research fields. A reliable, general, and facile synthetic protocol applicable for a large variety of 2D TMOs is in emergent demand. S-S/Se-Se bonds widely exist in various metal sulfide/selenide layered crystals....
