This paper examines directed networks in which the payoff of a player depends on the total number links formed by her and the other players. After showing that these networks with global spillovers may not always have Nash equilibria in pure strategies, we introduce two additional properties for...

For the connections model of strategic network formation, with two-way flow of information and without information decay, specific parameter configurations are given for which Nash networks do not exist. Moreover, existence and the scope of Nash network architectures are briefly discussed.

We examine in controlled experiments how individuals make choices when faced with multiple options. The choice tasks mimic the selection of health insurance, prescription drug, or retirement savings plans. However, in our experiment, the available options can be objectively ranked. We find that...

Heterogeneity in Nash networks can arise due to differences in the following four variables: (i) the value of information held by agents, (ii) the rate at which information decays or loses its value as it traverses the network, (iii) the prob- ability with which a links transmits information,...

This paper addresses the existence of Nash networks for the one-way flow model of Bala and Goyal (2000) in a number of different settings. First, we provide conditions for he existence of Nash networks in models where costs and values of links are heterogenous and players obtain resources from...

This paper examines the effect of household access to microcredit upon work by seven to eleven year old children in rural Malawi. Given that microcredit organizations foster household enterprises wherein much child labor is engaged, this paper aims to discover whether access to microcredit might...
