| Agricultural agencies have long offered agri-environmental payments that are inadequate to achieve water quality goals, and many state water quality agencies are considering point-nonpoint trading to achieve the needed pollution reductions. This analysis considers both targeted and nontargeted agrienvironmental payment schemes, along with a trading program which is not spatially targeted. The degree of improved performance among these policies is found to depend on whether the programs are coordinated or not, whether double-dipping (i.e., when farmers are paid twice-once by each program-to undertake particular pollution control actions) is allowed, and whether the agri-environmental payments are targeted. Under coordination, efficiency gains only occur... |

| Bovine tuberculosis (bTB) in cattle has caused significant economic losses to livestock producers and has proven difficult to eradicate. It is suspected that cattle movement across different farms and regions is one of the key factors of bTB transmission in the United States. Prior attempts to model the epidemiology of bTB infection within cattle to predict disease transmission have not adequately captured the behavioral aspects of trade. A better understanding of livestock trade patterns would help in predicting disease transmission and the associated economic effects. In this paper, we develop a gravity model of livestock trade and link it to an epidemiological model of bTB transmission, with the goal being that this information could lead to improved... |

| Increasing human interference with natural systems causes us to re-think our perception of wildlife species and the economic choices society makes with regards to their management. Accordingly, we generalize existing 'bioeconomic' models by proposing an economically-based classification of species. The theoretical model is applied to the case of African elephant management. We demonstrate that the classification of the steady state population of a species depends on both species' density and economic factors. Our main results are threefold. First, we demonstrate the classification-dependent possibility of multiple equilibria and perverse comparative statics for multi-use species. Second, upon comparing the optimal stock of a multi-use species to the... |

| Water quality is a major environmental issue. Pollution from nonpoint sources is the single largest remaining source of water quality impairments in the United States. Agriculture is a major source of several nonpoint-source pollutants, including nutrients, sediment, pesticides, and salts. Agricultural nonpoint pollution reduction policies can be designed to induce producers to change their production practices in ways that improve the environmental and related economic consequences of production. The information necessary to design economically efficient pollution control policies is almost always lacking. Instead, policies can be designed to achieve specific environmental or other similarly related goals at least cost, given transaction costs and any... |

| We propose a novel explanation for the emergence of language in modern humans, and the lack thereof in other hominids. A coevolutionary process, where trade facilitates speech and speech facilitates trade, driven by expectations and potentially influenced by geography, gives rise to multiple stable development trajectories. While the trade-speech equilibrium is not an inevitable outcome for modern humans, we do find that it is a relatively likely result given that our species evolved in Africa under climatic conditions supporting relatively high population densities. |

| Most economic studies of pollution control analyze policies that are optimal for a given set of underlying parameters. Less understood is how such policies perform when the underlying parameters change and policies are not adjusted in response, or what the benefits of adjustment are. We construct several measures of welfare sensitivity and use them to analyze the welfare impacts arising in a simulation of second-best, agri-environmental policies. |

| The beginnings of agriculture, or the agricultural revolution, is now recognized to be the widespread adoption of known practices – a change in behavior – as opposed to a phenomenon of discovery and innovation. In this paper, we combine elements of three theories—climate change, property rights, and competitive exclusion—to create a paleoeconomic model of agriculture and its diffusion. We focus on climate change as a necessary trigger, which combined with group property rights and competitive exclusion processes produced conditions sufficient for the diffusion of early agriculture. In contrast to other models in which farming emerges as technological progress or climate makes it a more productive option than hunting, farming emerges in our model even if... |

| We build a stylized model to gain insights into the application of conservation payments to protect endangered species in the face of wildlife-livestock disease risks and habitat fragmentation. Greater connectivity of habitat creates an endogenous trade-off. More connectedness ups the chance that populations of endangered species will grow more rapidly; however, greater connectivity also increases the likelihood that diseases will spread more quickly. We analyze subsidies for both habitat connectedness and livestock vaccination. We find the cost-effective policy is to initially subsidize habitat connectivity rather than vaccinations; this increases habitat contiguousness, which eventually also increases disease risks. Once habitat is sufficiently... |

| Owing to the fundamental importance of food to human welfare and of climate to crop and livestock production, agriculture has been a focus of research on the impacts of climate change and variability. This research has been largely concerned with implications for the supply and cost of food and for producer incomes. Societal interest in agriculture is, however, much broader than these issues. Agriculture is a source of several positive and negative environmental externalities. Several studies have been directed at the effects of climate change on the negative environmental externalities from agricultural production, including runoff, leaching, and erosion. These studies excel at modeling the biological and physical relationships and processes... |
