We assess the impact of being able to substitute an unlimited but costly energy substitute (like wind, solar) for a non-renewable resource (like oil, coal) in a model of sustainable growth. The prospects for sustainability on the optimal path depend crucially on the costs of this substitute....

We introduce endogenous directed technical change into numerical integrated climate and development policy assessment. We distinguish expenditures on innovation (R&D) and imitation (international technology spillovers) and consider the role of capital investment in creating and implementing new...

This paper extends the concept of the resource curse by studying whether and through which transmission channels natural resource wealth affects social spending. Even though the availability of vast natural capital reserves has commonly been linked to the neglect of human development, most of...

Recent survey data revealed that many California citrus growers did not know whether or not important beneficial insects were found on their fields while other growers were relying heavily or even entirely on these insects for pest control. Some pesticides are toxic both to the targeted pest and...

This paper presents a model of pest impacts in a multispecies framework. Strong detrimental relationships often form between pest populations and other biota, damaging ecosystem services and reducing social welfare. Under these circumstances, optimal pest management must account for the...

This paper examines how conservation decisions are affected by environmental degradation. Donations to an environmental NGO and participation in actual conservation activities capture individual preferences for environmental conservation. Environmental degradation is measured both through...

Eco-certification of coffee, timber and other high-value agricultural commodities is increasingly widespread. In principle, it can improve commodity producers' environmental performance, even in countries where state regulation is weak. But eco-certification will have limited environmental...

This paper presents a simple model of a common access fishery where fishermen care about relative performance as well as absolute profits. Our model captures the idea that status (which depends on relative performance) in a community influences a person's well-being. In our main specification,...

This paper analyzes the role of property rights in soil conservation. The conventional wisdom in soil conservation and property rights argues that tenants invest less than landlords in sustainable management practices and tend to overexploit soil biota services. The paper examines how this issue...

The way in which natural and physical capital are accumulated, distributed and harnessed underpins the functioning and sustainability of the productive system of each society as well as its social stratification. Significant changes in the interactions between natural and physical capital...
