Welfare measures under threats of environmental catastrophes are studied using the "“parable”" apparatus of Weitzman and Lofgren [22]. The occurrence probability of the catastrophic event is driven (at least partly) by anthropogenic activities such as natural resource exploitation. Without...

Uncertainty enters the dynamic tradeoffs of environmental and natural resource management in a variety of ways and forms. In this chapter we review the various sources of uncertainty, the methodologies developed to account for them and implications regarding management of environmental and...

Unintended consequences of announcing a climate policy well in advance of its implementation have been studied in a variety of situations. We show that a phenomenon akin to the so-called “Green- Paradox” holds also when the policy implementation date is uncertain. Governments are compelled,...

We characterize the dynamics of energy markets in which energy is derived from polluting (fossil) and clean (solar) resources. The analysis is based on geometric optimal control considerations. An important feature of solar energy technologies is that their cost of supply is predominantly due to...

Welfare measures under threats of environmental catastrophes are studied using the "parable" apparatus of Weitzman and Lofgren [22]. The occurrence probability of the catastrophic event is driven (at least partly) by anthropogenic activities such as natural resource exploitation. Without...

Under risk of catastrophic climate change, the occurrence hazard is added to the social discount rate. As a result, the social discount rate (i) increases and (ii) turns endogenous to the global warming policy. The second effect bears profound policy implications that are magnifed by economic...

Environmental consequences of natural resource exploitation often entail threats of future occurrences of detrimental abrupt events rather than (or in addition to) inflicting a damage gradually. The possibility of abrupt occurrence of climate-change related calamities is a case in mind. The...

Regulation of nonpoint source pollution often relies in one way or another on policy instruments based on ambient indicators. For well-known reasons, enforcement of ambient-based policies is, at best, limited. If no individual choices or actions are observed, than ambient-based regulation might...

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...

Exploitation diminishes the capacity of renewable resources to with-stand environmental stress, increasing their vulnerability to extreme conditions that may trigger abrupt changes. The onset of such events depends on the coincidence of extreme environmental conditions (environmental threat) and...
