Capital theory is a cornerstone of modern economics. Its ideas are fundamental for dynamic equilibrium theory and its concepts are applied in many branches of economics like game theory, resource and environmental economics, although this may not be recognized on a first glance. In this monograph, an approach is presented, which allows to derive important results of capital theory in a coherent and readily accessible framework. A special emphasis is given on infinite horizon and overlapping generations economics. Irreversibility of time, or the failure of the market system appear in a different light if an infinite horizon framework is applied. To bridge the gap between pure and applied economic theory, the structure of our theoretical approach is integrated in a computable general equilibrium model

We analyze the strategic interaction between mitigation and adaptation in a non-cooperative game in which regions are players and mitigation and adaptation are perfect substitutes in protecting against climate impacts. We allow for step by step decision making, with mitigation chosen first and adaptation second, and where the benefits of mitigation accrue only in the future. If marginal costs of adaptation decline with global mitigation, high income regions simultaneously invest in mitigation and adaptation. Low income regions engage in mitigation only.
