| We study optimal adaptation to climate change when the harmful consequences of global warming are associated with stochastic occurrence of abrupt changes. The adaptation policy entails the accumulation of a particular sort of capital that will eliminate or reduce the catastrophic damage of an abrupt climate change when (and if) it occurs. The occurrence date is uncertain. The policy problem involves balancing the tradeoffs between the (certain) investment cost prior to occurrence and the benefit (in reduced damage) that will be realized after the (uncertain) occurrence date. For stationary economies the optimal adaptation capital converges to a steady state. For growing economies the optimal adaptation capital stock approaches the maximal economic level... |

| Environmental policymakers must address the adverse effects of a number of pollutants that accumulate in the environment. Goals for the regulation of these damages often involve holding long-term emissions below a level deemed to be "dangerous", or outright banning of offending products or processes along with subsidization of more "green" alternatives. This paper builds upon previous studies by Keeler, Spence, and Zeckhauser (1971) and Tahvonen and Withagen (1996) in addressing the optimal long-term management of an accumulative but assimilatable pollutant through policies that restrict more damaging production processes and thereby induce more benign alternatives. Using a simple general equilibrium approach, we consider the possibility that the... |

| For the mitigation of long-term pollution threats, one must consider that both the process of environmental degradation and the switchover to new and cleaner technologies are dynamic. We develop a model of a uniform good that can be produced by either a polluting technology or a clean one; the latter is more expensive and requires investment in capacity. We derive the socially optimal pollution stock accumulation and creation of nonpolluting production capacity, weighing the tradeoffs among consumption, investment and adjustment costs, and environmental damages. We consider the effects of changes in the pollution decay rate, the capacity depreciation rate, and the initial state of the environment on both the steady state and the transition period. The... |

| We propose a test of the Porter hypothesis for the Dutch horticulture sector, using a stochastic production frontier analysis allowing for an inclusion of policy variables to account for the effect of environmental policy of firm performance. We find considerable heterogeneity in the way firms react to environmental policy measures. Our estimation results indicate, for example, that a 1997 voluntary agreement covering energy, nutrient and pesticides use enhances technical efficiency of vegetable and plants growers, contrary to specialised flower growers. Specialised flower growers, however, did react to the 1993 multi-year agreement on energy reduction, contrary to vegetable and plant growers. Summarising, our findings are mixed but do not seem to reject... |
