Hatfield, John William; Kominers, Scott Duke; Nichifor, … - In: Theoretical Economics 16 (2021) 1, pp. 197-234

In a general model of trading networks with bilateral contracts, we propose a suitably adapted chain stability concept … that plays the same role as pairwise stability in two-sided settings. We show that chain stability is equivalent to … stability if all agents' preferences are jointly fully substitutable and satisfy the Laws of Aggregate Supply and Demand. In the …

Dynamics of information exchange in endogenous social networks

Bimpikis, Kostas; Ozdaglar, Asuman; Acemoglu, Daron - In: Theoretical Economics 9 (2014) 1

We develop a model of information exchange through communication and investigate its implications for information aggregation in large societies. An \textit{underlying state} determines payoffs from different actions. Agents decide which others to form a costly \textit{communication link} with,...

Dynamics of strategic information transmission in social networks

Förster, Manuel - In: Theoretical Economics 14 (2019) 1, pp. 253-295

We develop a dynamic framework of strategic information transmission through cheap talk in a social network. Privately informed agents have different preferences about the action to be implemented by each agent and repeatedly communicate with their neighbors in the network. We first characterize...

Bottleneck links, essential intermediaries, and competing paths of diffusion in networks

Manea, Mihai - In: Theoretical Economics 16 (2021) 3, pp. 1017-1053

We investigate how information goods are priced and diffused over links in a network. A new equivalence relation between nodes captures the effects of network architecture and locations of sellers on the division of profits, and characterizes the topology of competing (and potentially...

Efficient partnership formation in networks

Bloch, Francis; Dutta, Bhaskar; Manea, Mihai - In: Theoretical Economics 14 (2019) 3, pp. 779-811

We analyze the formation of partnerships in social networks. Players need favors at random times and ask their neighbors in the network to form exclusive long-term partnerships that guarantee reciprocal favor exchange. Refusing to provide a favor results in the automatic removal of the...

A general framework for rational learning in social networks

Mueller-Frank, Manuel - In: Theoretical Economics 8 (2013) 1

This paper provides a formal characterization of the process of rational learning in social networks. Agents receive initial private information and select an action out of a choice set under uncertainty in each of infinitely many periods, observing the history of choices of their neighbors....

A general analysis of boundedly rational learning in social networks

Mueller-Frank, Manuel; Neri, Claudia - In: Theoretical Economics 16 (2021) 1, pp. 317-357

We analyze boundedly rational learning in social networks within binary action environments. We establish how learning outcomes depend on the environment (i.e., informational structure, utility function), the axioms imposed on the updating behavior, and the network structure. In particular, we...

A theory of school choice lotteries

Kesten, Onur; Ünver, M. Utku - In: Theoretical Economics 10 (2015) 2

notions of fairness in lottery design based on ex-ante stability. This framework unifies known many-to-one and one … ex-ante stability, equal treatment, and constrained ordinal-Pareto-efficiency. …
