Persistent and significant privately held stockpiles of minerals have long been an important empirical regularity in the United States. Such stockpiles would not rationally be held in a traditional Hotelling-style model, though firms could be willing to hold inventories if extraction costs are...

As the importance of addressing climate change increases the future global role for nuclear power, the demand for uranium will increase. Expanded uranium reserves will be needed to meet this increased demand, highlighting the importance of future exploratory efforts. To shed light on the social...

In this paper, we present an economic analysis of CO2-enhanced oil recovery (EOR). This technique entails injection of CO2 into mature oil fields in a manner that reduces the oil's viscosity, thereby enhancing the rate of extraction. As part of this process, significant quantities of CO2 remain...

This paper is the first to examine the public economics of export-based externalities arising within the provisioning of ecosystem services, with direct application to policies to prevent the spread of hitchhiking invasive species. We find when risk enters through exports, policy makers face a...

In this paper, we develop a paleoeconomic model of the co-evolution of economic specialization and encephalization--the common physiological measure of intelligence as reflected by brain mass relative to total body mass. Our economic analysis links ecological and social intelligence theories of...

Connected habitats are ecologically more valuable than isolated habitats for many species. A key challenge when designing payments for biodiversity in fragmented landscapes is to increase the spatial connectivity of habitats. Based on the idea of an agglomeration bonus we consider a scheme in...
