We characterize x-directional monotone comparative statics in function spaces, generalizing the results in Barthel and Sabarwal (2018) for finite-dimensional Euclidean spaces, and showing that their proofs generalize to infinite-dimensional spaces. Our generalizations include those for...

We generalize standard models with complementarities used widely in economics and other disciplines. We unify and expand their foundations, increase their scope of application, and identify previously unknown structural relationships among equilibrium sets in these models. Widely used results...

We study proliferation of an action in binary action network coordination games that are generalized to include global effects. This captures important aspects of proliferation of a particular action or narrative in online social networks, providing a basis to understand their impact on societal...
