Abstract
Our interest is in the relationship between the environment and economic growth. Because various interest groups see this issue differently, the typical optimization approach based on representative agent is not suitable. This is mainly because assessing the relative weight between consumption and environment in the utility function in a democracy is a sensitive political process. On the other hand, constraints on capital, consumption, and pollution levels should be agreed considerably easier than the aforementioned weight because the constraints refer to quantifiable measures. We propose that a regulator can look for a feasible strategy for emission control that will maintain capital, consumption, and pollution in a closed set of constraints. Such a strategy is called viable in viability theory. Viability theory is the study of dynamic systems that asks what set of initial conditions will generate evolutions that obey the laws of motion of a system and remain in a certain state constraints set for the duration of the evolution. We apply viability theory to a neoclassical model to identify which current economic states are sustainable under smooth adjustments of abatement-rate in the future. Among many observations, we note that countries that embark on an ambitious abatement program may fail to maintain their economies within the state constraints if their present levels of capital and consumption are low.
