;; INTERPERSONAL CHANNELS AND INNOVATION DIFFUSION - FIRST VERSION 11.06.2015
;; this model catch the opinion formation among economic agents toward an incremental innovation as influenced by the social interplay with other agents
;; agents are persuaded to adopt if their opinion is positive and exceeds a certin treshold
;; the main drivers of persuation are the opinion of the other agents the subject interact with
;; the model reproduce the web of relations among a real local productive system of agricultural firms 
;; the model is calibrated to obtain a percentage of adopters similar to the one observed in real data
;; the aim is to model policy actions able to make more speedy and effcient the innovation spread (in terms of positive opinion formation)

## WHAT IS IT?

The code example provides an illustration of how to import network data from external files.  This is useful when you have a specific network, perhaps created in another program or taken from real world data, that you would like to recreate in NetLogo.

It imports data from two different files.  The first is the "attributes.txt" file, which contains information about the nodes -- in this case, the node-id, size, and color of each node. The second is the "links.txt" file, which contains information on how the nodes are connected and the strength of their connection.

## NETLOGO FEATURES

The link primitives are used to represent and process connections between nodes.

The file primitives are used to read data from external files.
