Research Interest
Andrew Tilman is an ecological economist with the US Forest Service. His interest in working at the interface of economics and ecology grew out of his desire to use mathematical modeling to address environmental challenges. He received a Ph.D. from Princeton University for his work synthesizing approaches from economics, ecology, and game theory to address problems of the commons, including the management of fisheries, and global climate change action.

Feedback effects are a central feature of his current research interests. For example, human activity can cause environmental degradation. A degraded environment, in turn, can alter human behavior and resource use, causing feedback. Similar linkages exist between inequality and the biosphere. Environmental shocks, such as natural disasters, often exacerbate inequality. Conversely, high levels of inequality can be a barrier to effective community-based environmental stewardship. Together, this generates feedback that can alter social and environmental trajectories.

Eco-evolutionary game theory is a valuable tool for modeling human-environmental systems because it allows for the explicit consideration of feedback processes between human behavior and the environment. In an eco-evolutionary game, the strategies and actions of individuals impact the environment, and the state of the environment alters the incentives that people face. This modeling approach can help identify management practices that jointly achieve their environmental and social aims.
