Multi-Receiver Bayesian Perssuasion ✍️

We study the Bayesian persuasion problem with a single sender and multiple receivers, focusing on the network effects that the receivers exhibit. For example, we consider how information spillover between neighbors affects the sender's ability to persuade the population. Of particular interest are "defensive" strategies employed by receivers, which enable them to force the sender to send more informative signals and protect themselves from misinformation and fake news.

Information Propogation in Networks ✍️

We study the propagation of information (or adoption of new technologies, addictive products, and so forth) through a network, typically starting from an initial set of agents (the seed set) with the goal of reaching the entire network. The questions in this framework primarily concern the properties of the seed set, including finding it efficiently, determining its size, estimating the time required, and measuring the importance of each agent in the process.

Centrality Measure for Opinion Dynamics

Switching Costs and Persistent Actions

We study repeated interactions​ with long-term binding action. This includes situations where the action can be changed for some fee (switching costs), or can be changed to a particular direction (a bid can be increased but not decreased), or not at all. We characterize how such limitations affect the outcome of the game and compare it to the benchmark with no switching costs.

General Game Theory 

Game theory is everything, and everything is game theory. Sometimes, I work on gigs that fall outside the main scope of my research interests. This is the "miscellaneous category" for such projects. I'm always happy to expand my horizons and add new projects to this list.
