“price of oil hits record high”
“tribes fight over control of natural resources”
“government rations goods for duration of war”
these headlines all relate to the economic
concept of
(1) overproduction
(2) entrepreneurship
(3) interdependence
(4) scarcity

(4) scarcity or (2) entrepreneurship

Explanation:  

As you know on your topic(s) “Price of Oil Hits Record High” ; “Tribes Fight Over Control of Natural Resources” ; “Government Rations Goods for Duration of War” were based mostly on resources. It wouldn't be Interdependence since people unite as one which doesn't answer your topics. Nor can it be overproduction since "Tribes Fight Over Control of Natural Resources" in the headline you can see Tribes fight over the control of the resources so probably they are fighting over it cuz there isn't enough of something or someone might not use the little amount of resources wisely. The fact is that I feel Neutral on the entrepreneurship or the scarcity.
