where public money goes worldwide

Total amount
Number of payments

Results can be summarized as follows:

  1. There is one major node (payer) in the graph (Department of Defence), dispersing almost all (99%) the total budget (weight) of the graph. Obviously, defence has the lion’s stake in sub prime awards.
  2. Furthermore, all the money (92%) is received by CTA Inc. which is solely connected to the department of defence (no connections to other nodes).
  3. The dispersion of the public budget is made through 42 agents to the contractors. There are either payer or payee nodes in the graph (no mixed mode both payer and payee-except Smithsonian Inst.), consequently there are no brokers in the network resulting the diameter to equal 1 and the modularity fairly low at 0.022.
  4. Due to the above characteristics, there are mainly corporates of the defence-military sector (only US companies are eligible to become vendors due to legal restrictions) coupled by some major global enterprises with less weighted degree as they do not awarded purely defence contracts.

In the illustration above, we can see the major agents (payers & payees) in the network. The size of nodes in the graph is relevant to the amount of payments they give or receive(weighted degree). It is clearly seen the giant size of the 2 nodes that monopolize the exchange of funds (Dept. of Defence and CTA Inc.). It is worth noticing that 71% of the links (payment relations) are initiated from Dept. of Defence.
