Growing Stars: A Laboratory Analysis of Network Formation

Rong, Rong; Houser, Daniel - Interdisciplinary Center for Economic Science (ICES), … - 2012

reports reliable star network formation in an environment that includes ex ante heterogeneous agents. While heterogeneity may … explain network formation sometimes, it seems to play a smaller role in other cases (Feick and Price, 1987; Conley and Udry …, 2010). In this paper we investigate whether specific institutional conditions promote star network formation with ex ante …

Prescriptions for network strategy: Does evidence of network effects in cross-section support them?

Baum, Joel A.C.; Cowan, Robin; Jonard, Nicolas - United Nations University-Maastricht Economic Research … - 2012

Although intuitively appealing (and common), drawing network strategy implications from empirical evidence of network performance effects in pooled cross-section is not necessarily warranted. This is because network positions can influence both the mean and variance of firm performance....

Optimal health investment with separable and non-separable preferences

Azomahou, Theophile; Soete, Luc; Diene, Bity; Diene, Mbaye - United Nations University-Maastricht Economic Research … - 2012

We use a general equilibrium framework to study optimal health investment in a dynamic model where agents derive utility from consumption and health. The steady state and the dynamics of the model are studied under separable and non-separable preferences. A shock undermining health which...
