This paper evaluates the impact of the introduction of savings groups on poverty, vulnerability, and financial inclusion outcomes in rural Peru. Using a cluster randomized control trial and relying on both survey and administrative records, we investigate the impact of savings groups after more...

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...

We study a sequential-learning model featuring a network of naive agents with Gaussian information structures. Agents apply a heuristic rule to aggregate predecessors' actions. They weigh these actions according the strengths of their social connections to different predecessors. We show this...

Using a dataset of listed non-state-owned enterprises in China, we show that politically connected firms have a greater difficulty in obtaining trade credit than non-connected firms. This credit discrimination against politically connected firms strengthens when firms locate in regions with...

The paper proposes a game of weighted network formation in which each agent has a limited resource to form links of possibly different intensities with other agents and to use for private purposes. We show that every equilibrium is either "reciprocal" or "non-reciprocal". In a reciprocal...

The purpose of this paper is to explore the problem of power distribution within networks of relationships between companies and consumers (business-to-consumer (B2C) networks) and to examine the ways in which value is created and captured in such structures. To this end, we applied the network...

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...

We consider a natural generalization of Jackson and Wolinsky's (J Econ Theory 71:44- 74, 1996) connections model where the quality or strength of a link depends on the amount invested in it and is determined by a non-decreasing function of that amount. The information that the nodes receive...
