The formation of networks with local spillovers and limited observability

König, Michael David - In: Theoretical Economics 11 (2016) 3, pp. 813-863

This paper analyzes the formation of networks in which each agent is assumed to possess some information of value to the other agents in the network. Agents derive payoff from having access to the information of others through communication or spillovers via the links between them. Linking...

Chain stability in trading networks

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 …

Stochastic stability in monotone economies

Stachurski, John; Kamihigashi, Takashi - In: Theoretical Economics 9 (2014) 2, pp. 383-407

This paper extends a family of well-known stability theorems for monotone economies to a significantly larger class of … models. We provide a set of general conditions for existence, uniqueness and stability of stationary distributions when … monotonicity holds. The conditions in our main result are both necessary and sufficient for global stability of monotone economies …

Which networks permit stable allocations? A theory of network-based comparisons

Cheng, Chen; Xing, Yiqing - In: Theoretical Economics 17 (2022) 4, pp. 1473-1499

Economic agents care about their relative well-being, and the comparisons are usually local. We capture this using a network model, in which an agent's payoff depends on the ranking of their allocation among their network neighbors’. Given a network, an allocation is called α-stable if no...

Attack and interception in networks

Bloch, Francis; Chatterjee, Kalyan; Dutta, Bhaskar - In: Theoretical Economics 18 (2023) 4, pp. 1511-1546

This paper studies a game of attack and interception in a network, where a single attacker chooses a target and a path, and each node chooses a level of protection. We show that the Nash equilibrium of the game exists and is unique. We characterize equilibrium attack paths and attack...

Friends and enemies: A model of signed network formation

Hiller, Timo - In: Theoretical Economics 12 (2017) 3, pp. 1057-1087

I propose a simple model of signed network formation, where agents make friends to extract payoffs from weaker enemies. The model thereby accounts for the interplay between friendship and alliance on one hand and enmity and antagonism on the other. Nash equilibrium configurations are such that...
