Examining the value of carbon sequestration in a dynamic model, the authors demonstrate that unless the sequestration is permanent, it is only a fraction of the value of emission abatement. The magnitude of the fraction increases in the duration of sequestration, the natural decay rate of...

We examine the social efficiency of alternative intertemporal permit trading regimes. Banking with a 1-to-1 ratio and with a non-unitary intertemporal trading ratio (ITR) are compared with each other and with the no-banking permit trading regime. The more industry-wide shocks vary, and/or the...

We develop a dynamic model to investigate the optimal time paths of carbon emissions, sequestration, and the carbon stock. We show that carbon sinks should be utilized as early as possible, and carbon flow into sinks should last until the atmospheric carbon concentration is stabilized. We rule...
