Potential Economic Damage from Introduction of Brown Tree Snakes, Boiga irregularis (Reptilia: Colubridae), to the Islands of Hawai‘i.

v. ill. 23 cm.QuarterlyThe Brown Tree Snake (Boiga irregularis) has caused ecological and economic damage to Guam, and the snake has the potential to colonize other islands in the Pacific Ocean. This study quantifies the potential economic damage if the snake were translocated, established in the state of Hawai‘i, and causing damage at levels similar to those on Guam. Damages modeled included costs of medical treatments due to snakebites, snake-caused power outages, and decreased tourism resulting from effects of the snake. Damage caused by presence of the Brown Tree Snake on Guam was used as a guide to estimate potential economic damage to Hawai‘i from both medical- and power outage–related damage. To predict tourism impact, a survey was administered to Hawaiian tourists that identified tourist responses to potential effects of the Brown Tree Snake. These results were then used in an input-output model to predict damage to the state economy. Summing these damages resulted in an estimated total potential annual damage to Hawai‘i of between $593 million and$2.14 billion. This economic analysis provides a range of potential damages that policy makers can use in evaluation of future prevention and control programs

Macroeconomic impact of foot‐and‐mouth disease vaccination strategies for an outbreak in the Midwestern United States: A computable general equilibrium

The impacts of alternative responses to a hypothetical foot‐and‐mouth disease (FMD) outbreak occurring in the Midwestern United States are estimated using the Regional Economic Modelling Incorporated Policy Insight + (REMI) computable general equilibrium model, with particular attention paid to the employment impact estimates. The impact on employment and GDP is estimated using forecasts of a 10‐ year period with disease outbreak duration up to 2 years. Fifteen different vaccination protocols are compared to a disease control protocol that relies on animal depopulation with no vaccination. Results show that over the 10‐year study period, the strictly depopulation strategy that made no use of vaccination results in approximately 677,000 jobs lost with $47 billion GDP loss. Based on the analysis conducted, losses can be reduced through protocols that utilize vaccination strategies. Through a vaccinate‐to‐live strategy with the highest vaccination capacity and largest vaccination zone, savings can be as many as 509,000 jobs in comparison to the strategy that relies strictly on slaughter with no use of vaccination. By including detailed job losses by occupation, this study highlights the downstream employment effects and shows that job losses resulting from an FMD outbreak can go far beyond the farm sector impacts that have been reported in earlier studies. Understanding the impacts on employment by sector provides more actionable information than producer and consumer surplus estimates frequently reported in economic impact studies

Impact of COVID-19 on the US and Texas Economy: A General Equilibrium Approach

This paper examines the impact of COVID-19 on the US and Texas economy using a computable general equilibrium model, REMI PI+. We consider three scenarios based on economic forecasts from various sources, including the University of Michigan’s RSQE (Research Seminar in Quantitative Economics), IMF, and the Wi orld Bank. We report a GDP loss of $106 million (a 6$996 billion (a 5% decline) with 11.5 million jobs lost (5.5%) in the same year. By 2026, the aggregate total GDP loss in Texas ranges from $378 to$629 million. The estimated unemployment rate in Texas in 2021 ranges from 5% to 7.7%, depending on modeling assumptions. The granularity of the CGE results allow examination of the most and least impacted industries. Health Care and Social Assistance, Construction, and Accommodation and Food Services incur the most job loss while State and Local Government and Farm will likely see an increase in jobs for 2020. These insights separate our work from most current impact studies

Economic Impact of the Potential Spread of Vampire Bats into South Texas

Rabies transmitted by the common vampire bat is a major public health concern in subtropical and tropical areas of Latin America, and there is some concern that the species will eventually spread into south Texas. The objective of this study was to estimate the total economic impact of the potential spread of vampire bats into south Texas. Data on livestock populations and values in the relevant counties was combined with expected mortality rates to calculate livestock losses. An IMPLAN model of the regional economy was then used to estimate the secondary impacts experienced by other businesses in the region. These impacts were combined with estimates of increased expenditures on post-exposure prophylaxis and animal tests to derive the total economic impact. We estimated the total economic impact would be $7 million to$9.2 million annually if vampire bats spread to south Texas

A One Health Framework for the Evaluation of Rabies Control Programmes: A Case Study from Colombo City, Sri Lanka

<div><p>Background</p><p>One Health addresses complex challenges to promote the health of all species and the environment by integrating relevant sciences at systems level. Its application to zoonotic diseases is recommended, but few coherent frameworks exist that combine approaches from multiple disciplines. Rabies requires an interdisciplinary approach for effective and efficient management.</p><p>Methodology/Principal Findings</p><p>A framework is proposed to assess the value of rabies interventions holistically. The economic assessment compares additional monetary and non-monetary costs and benefits of an intervention taking into account epidemiological, animal welfare, societal impact and cost data. It is complemented by an ethical assessment. The framework is applied to Colombo City, Sri Lanka, where modified dog rabies intervention measures were implemented in 2007. The two options included for analysis were the control measures in place until 2006 (“baseline scenario”) and the new comprehensive intervention measures (“intervention”) for a four-year duration. Differences in control cost; monetary human health costs after exposure; Disability-Adjusted Life Years (DALYs) lost due to human rabies deaths and the psychological burden following a bite; negative impact on animal welfare; epidemiological indicators; social acceptance of dogs; and ethical considerations were estimated using a mixed method approach including primary and secondary data. Over the four years analysed, the intervention cost US $1.03 million more than the baseline scenario in 2011 prices (adjusted for inflation) and caused a reduction in dog rabies cases; 738 DALYs averted; an increase in acceptability among non-dog owners; a perception of positive changes in society including a decrease in the number of roaming dogs; and a net reduction in the impact on animal welfare from intermediate-high to low-intermediate.</p><p>Conclusions</p><p>The findings illustrate the multiple outcomes relevant to stakeholders and allow greater understanding of the value of the implemented rabies control measures, thereby providing a solid foundation for informed decision-making and sustainable control.</p></div

Economics of Invasive Species Damage and Damage Management

Annually, the estimated damage caused by invasive species in the United States has exceeded $100 billion, becoming one of the leading causes of environmental change and global biodiversity loss (Wilcove et al. 1998; Mack et al. 2000; Sala et al. 2000; Pimentel et al. 2005). Invasions by nonnative species highlight the undeniable link and feedback loops between ecological and economic systems (Perrings et al. 2002; Julia et al. 2007). Ecological systems determine if the conditions are suitable for invasion by nonnative species; however, economic systems help fuel the introduction of nonnative species and are themselves affected by invasive species when the ecosystem’s ability to provide services is diminished or when livestock or crops are made unmarketable (Julia et al. 2007). Invasive species have played an important role in U.S. agriculture. While some of the goods cultivated by the U.S. agricultural sector are indigenous plant and animal species, many are introduced; a minimum of 4542 species currently existing in the United States originated from outside its borders (Office of Technology Assessment 1993). Introduced species, such as corn, wheat, rice, as well as cattle, poultry, and other livestock, are all important commodities produced by the U.S. agricultural sector. Some introduced species have potential conservation values as well, providing food and shelter for native species, acting as catalysts for restoration, serving as substitutes for extinct species, and augmenting ecosystem services (Schlaepfer et al. 2011). A distinction can be drawn, then, between introduced species and invasive species. Like introduced species, invasive species are nonnative to that ecosystem; however, invasive species have the potential to cause harm, whether measured economically, environmentally, or as a human health hazard (The White House 1999)

The Economic Impact of Blackbird Damage to Crops

There are nearly 1,000 species of birds in North America, some of which provide obvious economic benefits like egg production, meat production, bird watching, or hunting (American Bird Association 2016). Some bird species, however, can cause a considerable amount of damage to U.S. agriculture, with estimates of annual damage caused by birds in the United States exceeding US$4.7 billion (Pimentel et al. 2005). Blackbirds (lcteridae) are one group of birds in North America that can cause significant economic damage to commercial grain crops, and to a lesser extent vine and tree crops (Wilson et al. 1989; Dolbeer 1990; Linz et al. 2011; Anderson et al. 2013). Four species of blackbirds-red-winged blackbird (Agelaius phoeniceus), common grackle (Quiscalus quiscula), yellow-headed blackbird (Xanthocephalus xanthocephalus), and brown-headed cowbird (Molothrus ater)-are primarily responsible for damage to sprouting and ripening grain crops (Lowther 1993; Twedt and Crawford 1995; Yasukawa and Searcy 1995; Peer and Bollinger 1997). During late winter, these species commonly can be found feeding on food present in concentrated animal feedlot operations (Dolbeer et al. 1978). For much of the year, however, these birds forage on insects, waste grain, and weed seeds, thus providing valuable ecological services

Economic Damages of Wild Pigs in Non-Traditional Areas: From the Fairway to the After Life

Invasive wild pigs are widely known to cause damage to agricultural properties and commodities, but less has been reported about damages to other types of property. A survey was distributed to golf courses and cemeteries across Texas to explore the extent of damage these properties experience. While both property types reported significant damages, golf courses were found to experience more damage than cemeteries. Using average reported costs and predicted county-level damage, total costs for all golf courses and cemeteries across the state were estimated to exceed $1.6 million USD per year

Direct, Spillover, and Intangible Benefits of Predation Management

Predation management is a controversial and often misunderstood reality of livestock management. Few on either side of the argument would believe that some sort of management is not necessary to limit livestock losses. Opposition to the lethal removal of predators characterizes most debates. While most of the opposition reflects a moral opinion about the manner in which people relate to the natural world, opponents of lethal control often argue that control is not economically justified. Simple economic justification would require that benefits of predation management outweigh the costs. If the only goal of predation management were to be economically efficient, minimization of costs would be one of the primary objectives; however, current predation management philosophies focus on minimum disruption to natural processes. These include focusing lethal management of offending individuals and populations, and using methods (such as aerial hunting) that are expensive but highly selective and humane. Boardman et al. (1996) discuss that the objective of minimizing costs is the same as maximizing net benefits. The costs of management, while important, play a minor role in the selection of management strategies. Costs of management include direct expenditures by producers for management programs, governmental expenditures for management and compensation programs, producer and governmental costs associated with preventing predation, and societal values associated with the predators removed. Costs of predation management programs are usually easier to quantify, can have significant variance and typically are concentrated to a few individuals, while the benefits are dispersed among many. For this reason, the authors intend to focus on the benefits of predation management programs

Cost–benefit analysis of controlling rabies: placing economics at the heart of rabies control to focus political will

Rabies is an economically important zoonosis. This paper describes the extent of the economic impacts of the disease and some of the types of economic analyses used to understand those impacts, as well as the trade-offs between efforts to manage rabies and efforts to eliminate it. In many cases, the elimination of rabies proves more cost-effective over time than the continual administration of postexposure prophylaxis, animal testing and animal vaccination. Economic analyses are used to inform and drive policy decisions and focus political will, placing economics at the heart of rabies control
