Product Concentration And Usage: Behavioral Effects In The Glyphosate Market, Edward D. Perry, David A. Hennessy, Giancarlo Moschini Jan 2019

Product Concentration And Usage: Behavioral Effects In The Glyphosate Market, Edward D. Perry, David A. Hennessy, Giancarlo Moschini

CARD Working Papers

People often ignore or misunderstand information that would help them make better decisions. For products that differ by concentration level, a critical choice concerns the correct dosage rate. We study the effects of changing glyphosate product concentration levels on farmers’ glyphosate usage behavior. Glyphosate is the world’s most widely used herbicide. After glyphosate went off patent in 2000, product variants with higher concentration levels entered the market. Using detailed farmlevel glyphosate use data in U.S. corn and soybeans over the period 1998-2011, we estimate the impact of product concentration levels on glyphosate application rates. We control for prices ...


Fishing Technologies: Specification And Estimation, Quinn Weninger, Larry Perruso, Helle Bunzel Dec 2018

Fishing Technologies: Specification And Estimation, Quinn Weninger, Larry Perruso, Helle Bunzel

Economics Working Papers

This paper consistently estimates the structural properties of a multiple-species fishing technology. Our approach overcomes two ubiquitous features of fisheries data generating processes that invalidate classical ordinary least squares estimators: (1) unobservability, by the researcher, of the in situ fish stock and its effect on productivity, and (2) endogenous production decisions that vary with fishermen’s private information about stock abundance and other economic variables. Our estimations obtain consistency by exploiting the timing of production decisions and the information available to fishermen when endogenous production scale and scope, i.e., targeting of individual species’, decisions are made. Our estimator adopts ...


Do Masked-Face Lineups Facilitate Eyewitness Identification Of A Masked Individual?, Krista D. Manley, Jason C.K. Chan, Gary L. Wells Dec 2018

Do Masked-Face Lineups Facilitate Eyewitness Identification Of A Masked Individual?, Krista D. Manley, Jason C.K. Chan, Gary L. Wells

Psychology Publications

Perpetrators often wear disguises like ski masks to hinder subsequent identification by witnesses or law enforcement officials. In criminal cases involving a masked perpetrator, the decision of whether and how to administer a lineup often rests on the investigating officer. To date, no evidence-based recommendations are available for eyewitness identifications of a masked perpetrator. In 4 experiments, we examined lineup identification performance depending on variations in both encoding (studying a full face vs. a partial/masked face) and retrieval conditions (identifying a target from a full-face lineup vs. a partial/masked-face lineup). In addition, we manipulated whether the target was ...

Risks And Opportunities Of Gm Crops: Bt Maize Example, Andrea K. Carzoli, Siddique I. Aboobucker, Leah L. Sandall, Thomas T. Lubberstedt, Walter P. Suza

Agronomy Publications

The anticipated world population growth emphasizes a need to produce more food on less land. Cutting-edge technologies, including genetic engineering, can help to develop improved crop varieties and protect natural resources. In spite of the potential for genetically-modified (GM) crops to make crop production more efficient, they remain a polarizing issue due to safety concerns. This paper provides an overview of the risk assessment process. The safety of Bacillus thuringiensis (Bt) proteins is used as an example for how risk assessment is applied to GM crops. Risks associated with GM crops have proven to be low to non-existent. Developing countries ...


Exploring School Foodservice Directors’ Intentions To Implement Farm-To-School Procurement Methods Considering Food Safety Practices, Sandra C. Curwood, Lakshman Rajagopal, Susan W. Arendt, Stephen Sapp Dec 2018

Exploring School Foodservice Directors’ Intentions To Implement Farm-To-School Procurement Methods Considering Food Safety Practices, Sandra C. Curwood, Lakshman Rajagopal, Susan W. Arendt, Stephen Sapp

Apparel, Events and Hospitality Management Publications

This study explored the intentions of foodservice directors' (FSD) who oversee Farm-to-School (F2S) programs to implement alternative procurement methods that better account for food safety practices. A web-based questionnaire was distributed to 864 California school FSDs with 136 (15.7%) usable surveys returned. Findings revealed that although FSDs understand the importance of food safety training and have confidence in their ability to manage produce safety practices, they express little intention to change their procurement practices. This finding might indicate a need for more resources and supportive policies.

La Evaluación De La Destreza Oral Una Comparación Entre Cursos "Híbridos A Distancia" Y "Presenciales Alao", Cristina Pardo-Ballester

World Languages and Cultures Publications

In the last decade, university institutions have been increasing, which demand from the teaching staff a greater offer of courses where technology is effectively incorporated into teaching. Critical studies published today, relating to the use of different technological tools in conjunction with language teaching, repeatedly contain the terms "distance learning" or "online course", as well as the terms "hybrid" or "combined" for make reference to the same model, to the same type of course. This study distinguishes two terms to refer to two models of courses: "hybrid at a distance" and "face-to-face ALAO". The oral dexterity of 132 participants was ...

Project Resilience: A community-based Resilience Initiative to engage rural adolescents towards healthy functioning

Project Resilience, a community-based resilience initiative was developed to address public concern. In the first part of the year of 2012 in a rural Mid-Atlantic state, eight adolescents and young adults died by suicide. Concerned public officials asked the Centers for Disease Control and Prevention (CDC) to assist with the epidemiologic investigation of these deaths. Mental health problems were found to be a significant contributing factor to the fatal suicide attempts. The scope of this paper will explore the potential influence of rural stress, trauma and violence ...


Accessibility And Health: An International Analysis Of Government Expenditure, Socioeconomic Development And Infant Mortality, Isaac Zvi Christiansen, Robert Mazur Nov 2018

Accessibility And Health: An International Analysis Of Government Expenditure, Socioeconomic Development And Infant Mortality, Isaac Zvi Christiansen, Robert Mazur

Journal of Critical Thought and Praxis

This research examines the relationship between government’s share of health expenditures and infant mortality (IMR). Public healthcare funding is a critical component of ensuring access to care for the poor. Financial barriers may lead to postponement of care, thereby exacerbating health outcomes. We find a moderate association between the government’s share of health expenditures and IMR and strong support for a multifaceted approach to accessibility that includes doctor density, vaccination coverage, improved water and sanitation, and female literacy in reducing IMR. Findings suggest that the effect of government’s share of health spending on IMR is stronger in ...

Designing Climate Policy: Lessons From The Renewable Fuel Standard And The Blend Wall, Gabriel E. Lade, C.-Y. Cynthia Lin Lawell, Aaron Smith Nov 2018

Designing Climate Policy: Lessons From The Renewable Fuel Standard And The Blend Wall, Gabriel E. Lade, C.-Y. Cynthia Lin Lawell, Aaron Smith

Economics Working Papers

Many policies mandate renewable energy production to combat global climate change. These policies often differ significantly from first-best policy prescriptions. Among the largest renewable energy mandates enacted to date is the Renewable Fuel Standard (RFS), which mandates biofuel consumption far beyond what is feasible with current technology and infrastructure. In this article, we critically review the methods used by the Environmental Protection Agency to project nearand long-term compliance costs under the RFS, and draw lessons from the RFS experience to date that would improve the program’s efficiency. The lessons are meant to inform both future RFS rulemaking and the ...


A Qualitative Investigation Of Farmer And Rancher Perceptions Of Trees And Woody Biomass Production On Marginal Agricultural Land, Ashley Hand, John Tyndall Oct 2018

A Qualitative Investigation Of Farmer And Rancher Perceptions Of Trees And Woody Biomass Production On Marginal Agricultural Land, Ashley Hand, John Tyndall

Natural Resource Ecology and Management Publications

Bioenergy produced from perennial feedstocks such as woody biomass could serve as an opportunity to strengthen local and regional economies and also jointly produce various environmental services. In order to assess the potential for biomass- based bioenergy, it’s essential to characterize the interest that potential biomass suppliers have in such an endeavor. In the U.S. Great Plains region, this largely means assessing relevant perceptions of farmers and ranchers. We conducted a series of farmer and rancher oriented focus groups in North Dakota, South Dakota, Nebraska and Kansas to qualitatively explore opinions about the role that trees can play ...

Firm Internal Network, Environmental Regulation, And Plant Death, Jingbo Cui, Giancarlo Moschini Oct 2018

Firm Internal Network, Environmental Regulation, And Plant Death, Jingbo Cui, Giancarlo Moschini

CARD Working Papers

This paper examines the role of a firm’s internal network in determining plant shutdown decisions in response to environmental regulations. Using unique plant-level data for U.S. manufacturing industries from 1990 to 2008, we find evidence that, in response to increasingly stringent environmental regulations at the county level, multi-plant firms do exercise their greater flexibility in adjusting production, relative to single-plant firms. Specifically, in regulated counties, the likelihood of a plant shutting down is higher for multi-plant firms. Moreover, we measure the firm internal network effect at the local, neighborhood, and the wider-area levels, as defined by the number ...
