Outline of Final Research Achievements |
Global environmental issues such as the global warming and the biodiversity loss have serious long-term consequences and several other novel features. Using nonlinear economic dynamics models incorporating those features, we analyzed the interaction between the society and the issues. The models are: dynamic game model with an environmental asset, non-concave optimal growth model, endogenous growth model with large and unpredictable shocks, and a social planner model for agents with non-exponential discounting. From them we have several new results as shown in “Research Performance” below. Some of them are found in our papers published in international journals. We also surveyed some related research issues that are recently extensively studied. They include the axiomatic approaches to intergenerational equity and the declining discount rate for social cost/benefit analysis. Our results help to understand why and when we choose an unsustainable path and to consider how to avoid it.
