This paper builds a theory of trust based on informal contract enforcement in social networks. In our model, network connections between individuals can be used as social collateral to secure informal borrowing. We de…ne network-based trust as the highest amount one agent can borrow from another agent, and derive a reduced-form expression for this quantity(More)
The success of future P2P applications ultimately depends on whether users will contribute their bandwidth, CPU and storage resources to a larger community. In this paper, we propose a new incentive paradigm, Networked Asynchronous Bilateral Trading (NABT), which can be applied to a broad range of P2P applications. In NABT, peers belong to an underlying(More)
We study whether individuals save more when information about their savings is shared with another village member (a “monitor”). We focus on whether the monitor’s effectiveness depends on her network position. Central monitors may be better able to disseminate information, and more proximate monitors may pass information to individuals who interact with the(More)
We show the existence of a pure strategy, symmetric, increasing equilibrium in double auction markets with correlated private valuations and many participants. The equilibrium we find is arbitrarily close to fully revealing as the market size grows. Our results provide strategic foundations for price-taking behavior in large markets.

We study the role of social interaction (SI) in determining firms’ employment adjustments in industrial districts. We assume that SI matters only among firms that are both similar -i.e. produce the same good and geographically close -i.e. located in the same district. Our first test is based on the correlation between individual and aggregate measures of(More)
The success of future P2P applications ultimately depends on convincing users to volunteer their bandwidth, CPU and storage resources, which is the challenge of incentive design. A natural approach to providing incentives in P2P applications is to use a single global currency, whereby peers earn currency units when contributing resources. Global currencies,(More)
There has been a steep increase in empirical research in economics in the past 20–30 years. This chapter brings together several actors and stakeholders in these developments to discuss their drivers and implications. All types of data are considered: official data, data collected by researchers, lab experiments, randomized control trials, and proprietary(More)
