Numbers of non-indigenous species--species introduced from elsewhere - are increasing rapidly worldwide, causing both environmental and economic damage. Rigorous quantitative risk-analysis frameworks, however, for invasive species lacking. We need to evaluate the risks posed by quantify relative merits different management strategies (e.g. allocation resources between prevention control). present a bioeconomic modelling framework analyse activity environment. The model identifies optimal...
Abstract We examine the net benefits of social distancing to slow spread COVID-19 in USA. Social saves lives but imposes large costs on society due reduced economic activity. use epidemiological and forecasting perform a rapid benefit–cost analysis controlling outbreak. Assuming that measures can substantially reduce contacts among individuals, we find about $5.2 trillion our benchmark case. magnitude critical parameters might imply negative benefits, including value statistical life...
International commerce in live organisms presents a policy challenge for trade globalization; sales of create wealth, but some nonindigenous species cause harm. To reduce damage, countries have implemented screening to limit the introduction damaging species. Adoption new risk assessment (RA) technologies has been slowed, however, by concerns that RA accuracy remains insufficient produce positive net economic benefits. This concern arises because only small proportion all introduced escape,...
Risk analysis of species invasions links biology and economics, is increasingly mandated by international national policies, enables improved management invasive species. Biological proceed through a series transition probabilities (i.e., introduction, establishment, spread, impact), each these presents opportunities for management. Recent research advances have estimates probability associated uncertainty. Improvements come from species-specific trait-based risk assessments (of impact...
The scientific community has come together in a mass mobilization to combat the public health risks of COVID-19, including efforts develop vaccine. However, success any vaccine depends on share population that gets vaccinated. We designed survey experiment which nationally representative sample 3,133 adults USA stated their intentions vaccinate themselves and children for COVID-19. factors we varied across treatments were: severity infectiousness COVID-19 source risk information (White House...
The scientific community has come together in an unprecedented effort to find a COVID-19 vaccine. However, the success of any vaccine depends on share population that gets vaccinated. We design survey experiment which nationally representative sample 3,133 adults U.S. state their intentions vaccinate themselves and children for COVID-19. In experiment, we account uncertainty about severity infectiousness COVID-19, as well inconsistencies risk communication from government authorities, by...
Emerging pandemics threaten global health and economies are increasing in frequency. Globally coordinated strategies to combat pandemics, similar current that address climate change, largely adaptive, they attempt reduce the impact of a pathogen after it has emerged. However, like mitigation have been developed include programs underlying drivers particularly animal-to-human disease transmission. Here, we use real options economic modeling globally adaptation for pandemic prevention. We show...
Mathematical epidemiology, one of the oldest and richest areas in mathematical biology, has significantly enhanced our understanding how pathogens emerge, evolve, spread. Classical epidemiological models, standard for predicting managing spread infectious disease, assume that contacts between susceptible individuals depend on their relative frequency population. The behavioral factors underpin contact rates are not generally addressed. There is, however, an emerging a class models addresses...
The rapid development of COVID-19 vaccines is a tremendous scientific response to the current global pandemic. However, per se do not save lives and restart economies. Their success depends on number people getting vaccinated. We used survey experiment examine impact vaccine intentions variety public health messages identified as particularly promising: three that emphasize different benefits from (personal health, others, recovery local national economies) one message emphasizes safety....

We used structured expert judgment and economic analysis to quantify annual impacts on ecosystem services in the Great Lakes, North America of nonindigenous aquatic species introduced by ocean-going ships. For US waters, median damages aggregated across multiple were 138 million per year, there is a 5% chance that for sportfishing alone losses exceeded 800 annually. Plausible scenarios future waters similar magnitude binational benefits shipping suggesting more serious consideration...
Physical distancing measures are important tools to control disease spread, especially in the absence of treatments and vaccines. While can safeguard public health, they also profoundly impact economy may have indirect effects on environment. The extent which physical should be applied therefore depends trade-offs between their health benefits economic costs. We develop an epidemiological-economic model examine optimal duration intensity aimed spread COVID-19. In application United States,...
Abstract Widespread testing is key to controlling the spread of COVID-19. But should we worry about self-selection bias in testing? The recent literature on willful ignorance says – people often avoid health information. In context COVID-19, such can data. Furthermore, arises when selfish wants conflict with social benefits, which might be particularly likely for potential ‘super-spreaders’ many interactions given who test positive are urged self-isolate two weeks. We design a survey...
<i>Because endangered species are in predator/prey, competitive, and other relationships with many who share their habitat, efficient conservation requires simultaneously considering the needs of species. Understanding ecological understanding how human activity affects these indirectly important to know when forming policies. We offer an integrated ecological/economic model that tracks both activities. The is applied Alaskan marine ecosystem which fish harvested Steller sea lions...
Although many migratory species are of conservation concern, traditional policies and economic analysis rarely address the unique characteristics species, limiting their impact. After a brief description key attributes this paper explores how those features alter approaches to answering critical policy questions: where, when, with what tools, which conserve? Because make movement decisions across space time, also considers joint question when where conserve. Policy that spatial–temporal...
Abstract A growing body of empirical evidence suggests that land use change, and the resulting decline in both area quality natural habitats, contributes to an increased incidence disease humans. Despite calls leverage conservation policy address burden linked ecosystem potential benefits are unknown. Efficiently reducing infectious through policies initiatives is challenging because it requires balancing trade-offs depend on ecological socioeconomic factors. To assess some these trade-offs,...
