This paper initiates a study of connections between local and global properties of graphical games. Specifically, we introduce a concept of local price of anarchy that quantifies how well subsets of agents respond to their environments. We then show several methods of bounding the global price of anarchy of a game in terms of the local price of anarchy. All our bounds are essentially tight.

The dynamic and complex relationship among economic variables has attracted the researchers, policy makers and business people alike. This study is an attempt to test the dynamic relationship among gold price, stock returns, exchange rate and oil price. All these variables have witnessed significant changes over time and hence, it is absolutely necessary to validate the relationship periodicall...

Many studies report the impact of various environmental chemicals on children’s neurological development as “clinically insignificant.” But this designation, which describes the individual child, does not always reflect the broader implications of exposure for the overall population—i.e., that a mild but frequent impact could add up to a substantial population-level burden. A new analysis estab...

The precious metal gold can be found at high concentration in tailings dumps and waste rock piles at many mining locations around the world. Conventional technology is generally unable to economically recover this residual gold, and, as a result, the potential resource is wasted, presenting environmental risk to the wider ecosystem through particulate and dissolved metal leaching and erosion. F...

We conducted preference assessments with 4 typically developing children to identify potential reinforcers and assessed the reinforcing efficacy of those stimuli. Next, we tested two predictions of economic theory: that overall consumption (reinforcers obtained) would decrease as the unit price (response requirement per reinforcer) increased and that the cost and benefit components that defined...
