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...

The IPAT-model developed by Ehrlich and Holdren is widespread in ecological economics in order to quantify the impact of population growth on environmental deterioration. We comment on this model and extensions proposed by several authors from a theoretical and empirical point of view.

We study the environmental and economic effects of public abatement in the presence of multiple stable steady-state ecological equilibria. Under shallow-lake dynamics (SLD), the isocline for the stock of pollution features two stable branches, a good and a bad one. Assuming that the ecology is...

Das ifo Institut hat im Auftrag des Umweltbundesamts die Teilnehmer am ifo Konjunkturtest nach ihrer Einschätzung einer »grünen Transformation« der Wirtschaft befragt. Eine grüne Wirtschaft erfordert Produkte, Produktionsprozesse und Dienstleistungen, die dazu beitragen, die wirtschaftliche...

We study the optimal control of a pollutant that accumulates with a delay.We find that optimal paths are, in general, non-monotonic and oscillatory, but monotonic if the objective function is additively separable. Hence, using additively separable objective functions as an approximation to a...

We examine the incidence and extent of co-authorship and intellectual collaboration in the leading journal of environmental and resource economics: the Journal of Environmental Economics and Management. Previous studies of general economic journals have offered empirical evidence for the fact...

Economics of the environment as an applied field of economics was established during the 1960s. At the time of its foundation, neoclassical environmental economics represented the mainstream view regarding the explanation of the causes of environmental problems and their solutions. Since then,...
