An Agent-Based Model of Internet Diffusion Under General and Specific Network Externalities v1.1.0

Using nodes from the 2002 General Social Survey sample, the code establishes a network of ties with a given homophily bias, and simulates Internet adoption rates in that network under three conditions: (i) no network externalities, (ii) general network externalities, where an individual’s reservation price is a function of the overall adoption rate in the network, (iii) specific network externalities, where reservation price is a function of the adoption rate in individual’s personal network, with varying degrees of homophily. Detailed description is available in: Paul DiMaggio and Filiz Garip. 2011. “How Network Externalities Can Exacerbate Intergroup Inequality.” American Journal of Sociology 116(6): 1887-1933.
