In a Ramsey policy regime, heterogeneity in beliefs about the potential costs of climate change is shown to produce policy ambiguities that alter carbon prices and taxation. Three sources of ambiguity are considered: (i) the private sector is skeptical, with beliefs that are unknown to the...

An economy with clean and dirty intermediate inputs may fall into a trap characterized by low environmental quality and low life expectancy, while the others converge to opposite steady states. We propose new strategies towards sustainable growth. They include: (i) taxes (subsidies) imposed on...

We investigate how a resource user who is present-biased manages a renewable resource stock with variable growth that could undergo a reversible regime shift (an abrupt, persistent change in structure and function of the ecosystem supplying the resource). In a discrete-time quasihyperbolic...

In this paper I propose a time-consistent method of discounting hyperbolically that contains the discount rate implied by Gamma discounting as a special case. I apply the discounting method to three canonical environmental problems: (i) optimal renewable resource use, (ii) the tragedy of the...

A conceptual approach is commonly needed to provide guidance for empirical analyses concerning the use of renewable resources such as rangelands. The theoretical model constructed in this paper captures the essential aspects of dynamic and stochastic issues associated with the management of...

This draft PhD thesis analyzes four issues in the research field that consists of the intersection of environmental economics, uncertainty, and decision-making. 1. Economic investments that lead to environmental damages beyond repair - like cutting rainforests or emitting pollutants with long...

We study the implications of climate change and the associated mitigation measures for optimal monetary policy in a canonical New Keynesian model with climate externalities. Provided they are set at their socially optimal level, carbon taxes pose no trade-offs for monetary policy: it is both...
