There's some market microstructure stuff that looks like this. I tried to find it earlier but was unsuccessful. I seem to remember one on network models of over the counter markets applied to federal funds rate if you want to poke around yourself. those networks are for both info AND trade which makes them easier to quantify.

Because the notion of pairwise stability is so important in the theory of network formation and equilibrium, there has been a few attempts to test it in experimental setups. I know at least two papers:

* [Myopic or farsighted? An experiment on network formation](http://www.ucllouvain.be/cps/ucl/doc/core/documents/coredp2011_7web.pdf), by Georg KIRCHSTEIGER1, Marco MANTOVANI, Ana MAULEON and Vincent VANNETELBOSCH.
* [Departures from Best Response in Market-like Link Formation: An experimental study](http://experiments.cob.calpoly.edu/seminars/fafchamps.pdf), by Margherita Comola and Marcel Fafchamps.

The first is a discussion paper. **A word of warning regarding the second** : the version of the paper that is linked is very much a draft. You might want to have a look to get an idea of what the authors plan on doing, but don't rely on it too much. I attended a talk where Fafchamps presented the paper this week, and he told us that **they initially got the wrong data from their experiment**. They only realized it rather recently and had to revise the whole paper. Because the linked draft is from February 2014, there are chances it is still based on the the old data (I did not read it).

For some field experiments on networks in development economics, you might want to have a look at other papers by Fafchamps :
