Temporal factors in resource dilemmas.
The conflict between present and future consumption lies at the heart of resource dilemmas (RDs), yet the role of time has received little attention in this research area. Emphasis was on factors related to the social rather than the temporal conflict inherent in an RD. We propose a model that deals explicitly with the temporal distribution of outcomes. The model combines three basic elements: a simple algebraic model, representing the RD's payoff structure; a growth function, reflecting the autonomous growth of the resource pool; and a discount function, describing how the temporal distance of outcomes affects their perceived value. The model provides a comprehensive framework for understanding the role of temporal factors in RD situations. It enables us to identify four relevant temporal RD characteristics (people's discount rates, their time horizon, the inter-trial delay, and the pool's growth rate) and to describe how these would be expected to affect people's tendency to cooperate. Theoretical, methodological and practical implications of the work are briefly discussed.
