This paper disentangles the topological assumptions of classical results (e.g.,Walker, 1977 on the existence of maximal …’s (1961) lemma on KKM correspondences, and the existence of fixed points for subordinate convex correspondences generalizing …

We prove existence and purification results for strategic environments possessing a product structure that includes … existence of pure-strategy equilibria allowing for infinite-dimensional externalities. Applied to stochastic games, the results … yield existence of stationary Markov perfect equilibria with extremal payoffs, which in turn yields existence of pure …

ensure existence of subgame perfect equilibria (SPE). We show that when Nature's moves are atomless in the original game … of He and Sun (2020) on existence of SPE without public randomization, which in turn yields equilibrium existence for …
