Demicontinuity and hemicontinuity in Fréchet space [PDF]
Proceedings of the American Mathematical Society, 1973 It is proved that the notions of demicontinuity and hemicontinuity for monotone maps from a Fréchet space into its dual are equivalent, thus generalizing a result of T. Kato.

Nearly Contraction Mapping Principle for Fixed Points of Hemicontinuous Mappings [PDF]
ISRN Applied Mathematics, 2013 We extend the application of nearly contraction mapping principle introduced by Sahu (2005) for existence of fixed points of demicontinuous mappings to certain hemicontinuous nearly Lipschitzian nonlinear mappings in Banach spaces. We have applied certain results due to Sahu (2005) to obtain conditions for existence—and to introduce an asymptotic ...

Which misspecifications persist?
Theoretical Economics, Volume 18, Issue 3, Page 1271-1315, July 2023., 2023 We use an evolutionary model to determine which misperceptions can persist. Every period, a new generation of agents use their subjective models and the data generated by the previous generation to update their beliefs, and models that induce better actions become more prevalent.

A common‐value auction with state‐dependent participation
Theoretical Economics, Volume 17, Issue 2, Page 841-881, May 2022., 2022 This paper analyzes a common‐value, first‐price auction with state‐dependent participation. The number of bidders, which is unobservable to them, depends on the true value. For participation patterns with many bidders in each state, the bidding equilibrium may be of a “pooling” type—with high probability, the winning bid is the same across states and ...

Regularization method for Noor’s variational inequality problem induced by a hemicontinuous monotone operator [PDF]
Fixed Point Theory and Applications, 2012 في هذه الورقة، نقدم طريقة تنظيم لإيجاد حل لمشكلة عدم المساواة التباينية في نور التي يسببها مشغل رتيب نصف مستمر. علاوة على ذلك، يرتبط هذا الحل بمجموعة الصفر من التعيينات المعكوسة الرتيبة بقوة. وبالتالي، نظرًا لأننا لا نفترض الرتابة القوية للمشغل المدروس، فإن نتائجنا عامة وتوسع بعض النتائج المعروفة في الأدبيات.

The structure of equilibria in trading networks with frictions
Theoretical Economics, Volume 17, Issue 2, Page 801-839, May 2022., 2022 Several structural results for the set of competitive equilibria in trading networks with frictions are established: The lattice theorem, the rural hospitals theorem, the existence of side‐optimal equilibria, and a group‐incentive‐compatibility result hold with imperfectly transferable utility and in the presence of frictions.

Journal of Mathematics, Volume 2022, Issue 1, 2022., 2022 We propose a new fixed point theorem that completely characterizes the existence of fixed points for multivalued maps on finite sets. Our result can be seen as a generalization of Abian’s fixed point theorem. In the context of finite games, our result can be used to characterize the existence of a Nash equilibrium in pure strategies and can therefore ...

Pairwise Stable Matching in Large Economies
Econometrica, Volume 89, Issue 6, Page 2929-2974, November 2021., 2021 We formulate a stability notion for two‐sided pairwise matching problems with individually insignificant agents in distributional form. Matchings are formulated as joint distributions over the characteristics of the populations to be matched. Spaces of characteristics can be high‐dimensional and need not be compact.

Theoretical Economics, Volume 16, Issue 4, Page 1221-1248, November 2021., 2021 Harris, Reny, and Robson (1995) added a public randomization device to dynamic games with almost perfect information to ensure existence of subgame perfect equilibria (SPE). We show that when Nature's moves are atomless in the original game, public randomization does not enlarge the set of SPE payoffs: any SPE obtained using public randomization can be
