Article
Full-text available
To fulfill the United Nation’s Sustainable Development Goals (SDGs), it is useful to understand whether and how specific agricultural interventions improve human health, educational opportunity, and food security. In sub-Saharan Africa, 75% of the population is engaged in small-scale farming, and 80% of these households keep livestock, which repres...
Article

Identifying the drivers of vaccine adoption decisions under varying levels of perceived disease risk and benefit provides insight into what can limit or enhance vaccination uptake. To address the relationship of perceived benefit relative to temporal and spatial risk, we surveyed 432 pastoralist households in northern Tanzania on vaccination for fo...
Chapter
Livestock health and disease constrain animal protein production and trade, contributing directly to the health outcomes, livelihoods, and food security of almost a billion people worldwide. They also indirectly affect the diet, nutrition and health security of all people. Strong public interest in the matter arises from myriad external effects, in...
Article
Full-text available
Maternal and child under-nutrition resulting in childhood stunting remains prevalent in east Africa, leading to increased disease risk, limiting cognitive development, and impeding human capital accumulation that constrains individuals, communities, and nations from reaching their full potential. In a western Kenyan population with a high prevalenc...
Article
Full-text available
Polyethylene plastic mulches are widely used in specialty cropping systems in the United States due to the horticultural benefits they provide. However, polyethylene mulch is reapplied seasonally, generating large volumes of plastic waste that contribute to plastic pollution concerns. This review synthesizes scientific and industry findings to prov...
Article
Full-text available
This paper develops a model that allows for two-way interaction between infectious disease dynamics and economic dynamics. Our motivating application is the 2014 Ebola Virus Disease (EVD) outbreak in West Africa, where purposeful investments in disease control played an important role. We, therefore, unlike other papers in the literature, model two...
Article
Full-text available
Investments in animal health and Veterinary Services can have a measurable impact on the health of people and the environment. These investments require a baseline metric that describes the burden of animal health and welfare in order to justify and prioritise resource allocation and from which to measure the impact of interventions. This paper is...
Article
Full-text available
Anaplasmosis is a costly livestock disease that persists across the United States and the world. While the traditional control options of feed additives, vaccination, and post-infection antibiotic treatments exist, the highly infectious, often asymptomatic onset of anaplasmosis in cattle makes the optimal combination of disease control measures unc...
Article
The 2014–2015 H5N2/H5N8 highly pathogenic avian influenza (HPAI) epidemic required $879 million dollars in public expenditures to eradicate the disease from poultry production, making it the most costly animal health incident in US history. Cost and resource availability are important considerations when determining optimal response plans. However,...
Article
Full-text available
Background Developing disease risk maps for priority endemic and episodic diseases is becoming increasingly important for more effective disease management, particularly in resource limited countries. For endemic and easily diagnosed diseases such as anthrax, using historical data to identify hotspots and start to define ecological risk factors of...
Article
Full-text available
Understanding food insecurity issues is in part contingent on understanding food consumption and its costs. We develop estimates of protein, lipid, and carbohydrate macronutrient consumption from household food consumption in western Kenya. We then calculate the shadow price per gram of macronutrient consumption as a share-weighted expense-consumpt...
Article
Growing concern about the degradation of the environment and public health has called into question the use of conventional household batteries that are consumed and then typically discarded. Because most conventional batteries are not recycled, they end up in landfills where they decompose, potentially leaching harmful chemicals into the surroundi...
Article
Full-text available
To mitigate the environmental harm associated with the disposal of polyethylene (PE) (plastic) mulches after use—incineration, dumping at landfills, tilling into the soil, and onsite stockpiling—biodegradable plastic mulches (BDMs) are proposed as an environmentally friendly alternative. These mulches are designed to degrade in the field, thereby r...

Article
Full-text available
Vaccination for foot-and-mouth (FMD) disease remains low in parts of Africa despite the existence of vaccines. In East Africa, the presence of multiple virus serotypes and sub-types makes matching a vaccine with the circulating virus type in the field, or providing a high potency vaccine, a challenge. In this paper we use game theory to show that t...
Article
Full-text available
Understanding preferences for veterinary vaccines in low and middle-income countries is important for increasing vaccination coverage against infectious diseases, especially when the consumer is responsible for choosing between similar vaccines. Over-the-counter sales of vaccines without a prescription gives decision-making power to consumers who m...
Preprint
Full-text available
Decision-making in economics is largely framed by notions of risk preferences, consumption smoothing and stochastic changes in discounting. However, more recent empirical evidence indicates that direct measures of cognitive processes provide a more nuanced and predictively robust understanding of economic decision-making. The theoretical link betwe...
Preprint
The effects of poverty, independent of income, on decision-making is hypothesised to help explain persistent poverty. The link between changes in cognition and economic decision-making, while consistently identified in experimental settings, is only now emerging. Empirical evidence demonstrates that short-term cognitive ability may be consistently...
Article
Full-text available
Vaccination can be an effective risk management approach to minimize the burden of disease and increase livestock productivity for smallholder households in low income countries. In contrast to vaccination of cattle, a high-value smallholder asset, there is a significant knowledge gap for the drivers of vaccine adoption of smallholder poultry. Newc...
Article
Full-text available
Background Food security is critical to achieving sustainable growth, poverty reduction, and political and economic stability. Livestock have the potential to improve the food security of smallholder households in developing countries, but livestock productivity is constrained by disease. The extent to which households adopt innovations such as vac...

Livestock production in Africa is key to national economies, food security and rural livelihoods, and > 85% of livestock keepers live in extreme poverty. With poverty elimination central to the Sustainable Development Goals, livestock keepers are therefore critically important. Foot-and-mouth disease is a highly contagious livestock disease widespr...
Article
This study evaluates consumer preferences for an agricultural product grown on biodegradable mulch film, which is an environmentally friendly soil cover that sustains plant growth, but that avoids the environmental harm of plastic pollution from non-biodegradable mulches in the field or upon disposal. Using a dichotomous-choice contingent valuation...
Article
The market structure and recipes for beer has been rapidly changing with craft beers attracting more consumers. Perceived hops quality (hoppiness) is one of the main attributes that microbrewers alter to differentiate their products to satisfy consumers’ changing tastes and preferences. We hypothesize that, in addition to manipulating beer-processi...

Motivated by disease outbreaks and trade shocks, a dynamic equilibrium displacement model is calibrated for the U.S. pear industry to simulate welfare from various shocks compared to a baseline. Our contribution is assessing the impact to intermediary packers for fresh fruit and processors for processed fruit in addition to growers and consumers. T...
Article
For animal disease events the outcomes and consequences often remain unclear or uncertain, including the expected changes in benefits (e.g. profit to firms, prices to consumers) and in costs (e.g. response, clean-up). Moreover, the measurement of changes in benefits and costs across alternative interventions used to control animal disease events ma...

Economic shifts, regulatory change, and disasters always produce winners and losers. Whether or not these changes are good for the local economy, disasters both burden and provide opportunities for individual people, businesses, or groups—local and non-local. Disasters interrupt the stock and flow of resources for firm inputs, distort firm outputs,...

This study evaluates the economic consequences of hypothetical foot-and-mouth disease releases from the future National Bio and Agro Defense Facility in Manhattan, Kansas. Using an economic framework that estimates the impacts to agricultural firms and consumers, quantifies costs to non-agricultural activities in the epidemiologically impacted regi...
Article
Full-text available
This paper examines how maximum residue limits (MRLs) affect the optimal choice by growers of chemical applications to control pests and diseases. In practice, growers who export balance both yield risk and pesticide residue uncertainty when making chemical application decisions. To address these issues we specify an expected utility model and cali...
Article
This study evaluates the economic consequences of a Rift Valley Fever outbreak, a virus that spreads from livestock to humans, often through mosquitoes. Developing a ‘one health’ economic framework, economic impacts on agricultural producers and consumers, government costs of response, costs and disruptions to non-agricultural activities in the epi...
Article
A foot-and-mouth disease outbreak, although having a low probability of occurrence, results in losses of export markets and introduces considerable potential disease management and eradication costs. We develop a dynamic model that integrates beef cattle production, disease dissemination, domestic consumption, and international trade and captures t...
Article
Full-text available
As microbrew beers have become more popular, the intrinsic characteristics of beer have become more important in consumer purchasing decisions. We identify sensory properties that influence consumers' willingness to pay for beer using a contingent valuation model that includes subjective sensory evaluations and sociodemographic characteristics of c...
Article
Full-text available
Background: For most rural households in sub-Saharan Africa, healthy livestock play a key role in averting the burden associated with zoonotic diseases, and in meeting household nutritional and socio-economic needs. However, there is limited understanding of the complex nutritional, socio-economic, and zoonotic pathways that link livestock health...
Article
Phase space reconstruction is investigated as a diagnostic tool for determining the structure of detected nonlinear processes in regression residuals. Empirical evidence supporting this approach is provided using simulations from an Ikeda mapping and the S&P 500. Results in the form of phase portraits (e.g., scatter plots of reconstructed dynamical...

We propose a Generalized Quadratic Utility (GQU) model for an incomplete demand system with binding non-negativity constraints which is flexible in income and price effects. The model accounts for zero consumption using choke prices identified by the Kuhn-Tucker conditions. The GQU demand system is theoretically consistent and can overcome the anal...
Article
Full-text available
A generalized maximum entropy estimator is developed for the linear simultaneous equations model. Monte Carlo sampling experiments are used to evaluate the estimator's performance in small and medium sized samples, suggesting contexts in which the current generalized maximum entropy estimator is superior in mean square error to two and three stage...
Article
Full-text available
High tunnels are being used by specialty crop producers to enhance production yields and quality, extend growing seasons, and protect crops from extreme weather. The tunnels are unheated, plastic-covered structures under which crops are planted directly in the soil, and they provide greater environmental protection and control than open-field produ...
Article
Full-text available
Maximum entropy methods of parameter estimation are appealing because they impose no additional structure on the data, other than that explicitly assumed by the analyst. In this paper we prove that the data constrained GME estimator of the general linear model is consistent and asymptotically normal. The approach we take in establishing the asympto...
Article
Full-text available
We investigate dynamic market reactions from harmful events using phase space reconstruction to analyse nonlinear dynamical systems. Phase space reconstruction analysis is applied to US beef consumption data, demonstrating market deviations and transitions from plausible, stable consumption patterns in response to product attributes (latent or nonl...
