To date, little is known about how information flows within farmer groups and how extension interventions could be designed to deliver combined information on agriculture and nutrition. This study uses unique network data from 815 farm households in Kenya to investigate the structure and...

Researchers and practitioners of precision agricultural technology have worked to overcome adoption, cost, and environmental obstacles since its introduction. The next gap in the adoption continuum of profitable precision agricultural technologies is data and data use, the so-called Big Data....

The article focuses on the Italian financial system, proposing an analysis of the relational structure among listed financial companies and its evolution in recent years. In order to detect this structure, we investigate a specific kind of interorganizational tie, emerging when members of a...

We study an evolutionary model of a public good game with rewards played on a network. Giving rewards to contributors transforms the game but gives rise to a second-order dilemma. By allowing for coevolution of strategies and network structure, the evolutionary dynamics operate on both structure...

The existence of imitative behavior among consumers is a well-known phenomenon in the field of Economics. This behavior is especially common in markets determined by a high degree of innovation, asymmetric information and/or price-inelastic demand, features that exist in the pharmaceutical...

We study a non-cooperative model of unilateral network formation. Derks et al. [2008b] prove the existence of local-Nash and global-Nash networks for games with payoff functions that satisfy a framework of axiomatic properties. These properties are inspired by the one-way flow model, which is...

This paper combines the imperfect reliability model of Bala and Goyal [2000b] with the heterogeneous player model of Galeotti et al. [2006]. We compare existence, characterization and efficiency results in the resulting framework with the results in other frameworks allowing for imperfect...
