Building Up Social Capital in a Changing World: A Network Approach

Vega-Redondo, Fernando - 2003

are found. Over time, the underlying payoffs randomly change, i.e. display some "volatility", which leads agents to react …-run invariant behavior and obtain the following conclusions: (a) Only if payoff volatility is not too high can the society sustain a … dense social network. (b) The social architecture endogenously responds to increased volatility by becoming more cohesive …

Opinion dynamics under conformity

Buechel, Berno; Hellmann, Tim; Klößner, Stefan - 2012

We present a model of opinion formation where individuals repeatedly engage in discussion and update their opinion in a social network similarly to the DeGroot model. Abstracting from the standard assumption that individuals always report their opinion truthfully, agents in our model interact...

Gender Differences in Trust and Reciprocity

Chaudhuri, Ananish; Gangadharan, Lata - 2002

We use the investment game introduced by Berg, Dickhaut and McCabe (1995) to explore gender differences in trust and reciprocity. In doing so we replicate and extend the results first reported by Croson and Buchan (1999). We find that men exhibit greater trust than women do while women show much...

Media and social capital

Campante, Filipe R.; Durante, Ruben; Tesei, Andrea - 2021

We survey the empirical literature in economics on the impact of media technologies on social capital. Motivated by a simple model of information and collective action, we cover a range of different outcomes related to social capital, from social and political participation to interpersonal...

The Behavioral, Economic, and Political Impact of the Internet and Social Media: Empirical Challenges and Approaches

Sabatini, Fabio - 2023

This paper presents a review of empirical methods used to assess the behavioral, economic, and political outcomes of Internet and social media usage. Instead of merely surveying the various impacts of the Internet, we examine the methods adopted to identify these impacts. We describe two main...

Dynamics of information exchange in endogenous social networks

Bimpikis, Kostas; Ozdaglar, Asuman; Acemoglu, Daron - In: Theoretical Economics 9 (2014) 1, pp. 41-97

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,...

Cognitive empathy in conflict situations

Gauer, Florian; Kuzmics, Christoph - 2016

Two individuals are involved in a conflict situation in which preferences are ex ante uncertain. While they eventually learn their own preferences, they have to pay a small cost if they want to learn their opponent's preferences. We show that, for sufficiently small positive costs of information...

Optimal deadlines for agreements

Damiano, Ettore; Li, Hao; Suen, Wing - In: Theoretical Economics 7 (2012) 2, pp. 357-393

Costly delay in negotiations can induce the negotiating parties to be more forthcoming with their information and improve the quality of the collective decision. Imposing a deadline may result in stalling, in which players at some point stop making concessions but switch back to conceding at the...

Farvaque, Etienne; Mihailov, Alexander; Naghavi, Alireza - 2011

This paper aims to explain the rise and fall of communism by exploring the interplay between economic incentives and social preferences transmitted by ideology. We introduce inequality-averse and inefficiency-averse agents and analyze their conflict through the interaction between leaders with...

Diffusion of behavior in dynamic networks

König, Michael D. - 2017

We analyze binary choice models in communication networks, in which both, the formation of links in the network as well as the action choices are endogenous. We provide a complete characterization of the equilibrium action choices and networks, where agents choose their strategies - actions and...
