We analyze the optimal dynamic scale and structure of a two-sector-economy, where each sector produces one consumption good and one specific pollutant. Both pollutants accumulate at different rates to stocks that damage the natural environment, which acts as a dynamic driving force for the...

In this paper I extend the well known result that a hyperbolically discounting agent postpones costs into the future. If society has hyperbolic inter-temporal preferences, it may be optimal from an ex ante point of view to postpone structural change from a polluting to a non polluting production...

In this paper I study the optimal control path for a (capital or pollution) stock which accumulates time with a lag to its control. It is shown that the optimal control path is non-monotonic and cyclical in general, but it is monotonic if the objective function is additively separable in the...

We formulate an optimal control capital accumulation model with a Leontief-type production function and an exogenously given time-lag between investment and the accumulation of the capital stock, to analyze the qualitative and quantitative influence of time-lags on the system dynamics. As known...

In the wake of 25 UN Climate Change Conferences of the Parties (and counting), international cooperation on mitigating greenhouse gas emissions to avoid substantial and potentially irreversible climate change remains an important challenge. The limited impact that the Kyoto Protocol and its...

We analyse a principal-agent relationship in the context of international climate policy. Principals in two countries first decide whether to merge domestic emission permit markets to an international market, then delegate the domestic permit supply to an agent. We find that principals select...
