Revenue Comparisons of Auctions with Ambiguity Averse Sellers
Sosung Baik, Sung-Ha Hwang
We study the revenue comparison problem of auctions when the seller has a maxmin expected utility preference. The seller holds a set of priors around some reference belief, interpr…
Auction design with ambiguity: Optimality of the first-price and all-pay auctions
Sosung Baik, Sung-Ha Hwang
We study the optimal auction design problem when bidders' preferences follow the maxmin expected utility model. We suppose that each bidder's set of priors consists of beliefs clos…
The Effect of Social Distancing on the Reach of an Epidemic in Social Networks
Gregory Gutin, Tomohiro Hirano, Sung-Ha Hwang +2
How does social distancing affect the reach of an epidemic in social networks? We present Monte Carlo simulation results of a capacity constrained Susceptible-Infected-Removed (SIR…
Public goods in networks with constraints on sharing
Stefanie Gerke, Gregory Gutin, Sung-Ha Hwang +1
This paper considers incentives to provide goods that are partially shareable along social links. We introduce a model in which each individual in a social network not only decides…
Positive feedback in coordination games: stochastic evolutionary dynamics and the logit choice rule
Sung-Ha Hwang, Luc Rey-Bellet
We study the problem of stochastic stability for evolutionary dynamics under the logit choice rule. We consider general classes of coordination games, symmetric or asymmetric, with…
Strategic Decompositions of Normal Form Games: Zero-sum Games and Potential Games
Sung-Ha Hwang, Luc Rey-Bellet
We study new classes of games, called zero-sum equivalent games and zero-sum equivalent potential games, and prove decomposition theorems involving these classes of games. We say t…
Simple Characterizations of Potential Games and Zero-sum Games
Sung-Ha Hwang, Luc Rey-Bellet
We provide several tests to determine whether a game is a potential game or whether it is a zero-sum equivalent game---a game which is strategically equivalent to a zero-sum game i…
Decompositions of two player games: potential, zero-sum, and stable games
Sung-Ha Hwang, Luc Rey-Bellet
We introduce several methods of decomposition for two player normal form games. Viewing the set of all games as a vector space, we exhibit explicit orthonormal bases for the subspa…
Deterministic Equations for Stochastic Spatial Evolutionary Games
Sung-Ha Hwang, Markos Katsoulakis, Luc Rey-Bellet
Spatial evolutionary games model individuals who are distributed in a spatial domain and update their strategies upon playing a normal form game with their neighbors. We derive int…
