Do tropical typhoons smash community ties? Theory and Evidence from Vietnam

Zylberberg, Yanos - Development and Policies Research Center (Depocen) - 2010

In rural economies, risk-sharing arrangements through networks of relatives and friends are common. Monitoring issues seem to impede the development of informal insurance mechanisms at higher level. As such, after a large and covariate shock, the prerequisites under which informal arrangements...

Stability in informal insurances: an approach by networks and overlapping coalitions

Agbaglah, Messan - Département d'économique, Faculté d'administration - 2014

Based on empirical facts, we build a model of informal insurance institutions and study their stability. In our setting, risk sharing groups are overlapping homogenous coalitions, originating from networks of historical trust relationships. We derive a general folk theorem that works in an...

Motives for sharing in social networks

Ligon, Ethan; Schechter, Laura - In: Journal of Development Economics 99 (2012) 1, pp. 13-26

What motivates people in rural villages to share? We first elicit a baseline level of sharing using a standard, anonymous dictator game. Then using variants of the dictator game that allow for either revealing the dictator's identity or allowing the dictator to choose the recipient, we attribute...

The degree measure as utility function over positions in networks

Brink, René van den; Rusinowska, Agnieszka - 2017

In this paper, we connect the social network theory on centrality measures to the economic theory of preferences and … different networks. The famous degree measure assigns to every position in a weighted network the sum of the weights of all … links with its neighbours. A crucial property of a preference relation over network positions is neutrality to ordinary risk …

Games Under Network Uncertainty

Chaudhuri, Promit K.; Sarangi, Sudipta; Tzavellas, Hector - 2023

We consider an incomplete information network game in which agents’ information is restricted only to the identity of … walks they have in the network. Our model clearly demonstrates how asymmetric information based on network position and the … identity of agents affect strategic behavior in such network games. We also characterize agent behavior in equilibria under …

Financial Market Responses to a Natural Disaster: Evidence from Local Credit Networks and the Indian Ocean Tsunami

Czura, Kristina; Klonner, Stefan - 2018

Conventional wisdom in economics holds that traditional credit and insurance networks are inapt for insuring against covariate risks such as natural hazards. We challenge this claim by examining changes in financial allocations in Rotating Savings and Credit Associations (Roscas), a popular...
