Bandwidth, latency and price Can a market be seen as a set of nodes (market actors) connected by edges with bandwidth and latency characteristics?

Are these terms used in economics?

If so would an import tariff affect bandwidth and/or latency?
There is an active body of research on network economics. See, for example,


Social and Economic Networks by Jackson
Connections by Goyal


for an introduction to the topic.

These models occasionally use weighted edges ("bandwidth") to model economic phenomena. 

I'm not aware of work making use of the concept of latency, except when literally modelling latency (as in models of network congestion). An example of such a paper (though without the notion of nodes or edges) is Net neutrality and investment incentives by Choi and Kim.
