Toxic Effects Of Lead Disposal In Water: An Analysis Of Tri Facility Releases, Patrick Koval Aug 2018

Toxic Effects Of Lead Disposal In Water: An Analysis Of Tri Facility Releases, Patrick Koval

Economics Department Working Papers

Using county-level TRI data from 2003 to 2016, I find evidence that lead emissions in water adversely affect birth weights within the emitting county, especially with respect to the percentage of births considered low birth weight within that county (less than 2,500 grams). I find that a one percent increase in lead emissions per square mile increases the proportion of low birth weights by 0.27 percentage points. For a county with an average number of births in a particular year, this one percent increase in lead per square mile translates to an additional $475,000 in hospitalization costs ...


National Competent Authorities As The Reference Member State: Understanding The Variables Affecting Their Regulatory Decisions, Christian Martin Jan 2018

National Competent Authorities As The Reference Member State: Understanding The Variables Affecting Their Regulatory Decisions, Christian Martin

Undergraduate Honors Theses

The pharmaceutical medicines in one member state of the European Union do not belong in any other member state unless that member state’s national medicines agency has approved them. In this paper I look at the two procedures that exist, the mutual recognition procedure and the decentralized procedure. I ask what affects the variation in ease and stringency within the regulatory decisions of the national competent authorities when acting as the reference member state. I hypothesize that institutions and economic political ideology influence the regulatory decisions, leading to more or less finalized procedures. Multi-variate regressions confirm the permeability of ...


Do Farm Subsidies Affect Crop Diversification?, Chadwick O'Neal Apr 2017

Do Farm Subsidies Affect Crop Diversification?, Chadwick O'Neal

Georgia College Student Research Events

The United States spends $20 billion each year on farm subsidies. Farmers face increased risk and income variation when their crop portfolio is less diversified. It’s possible for farm subsidies to decrease diversification if they are focused on specific crops. Utilizing state level subsidy and agricultural data from the Environmental Working Group, I used econometric analysis to estimate the effect of farm subsidies on crop diversification. I used the number of acres planted from the 15 top most subsidized and grown crops in the United States to derive my dependent variable, the Herfindahl-Hirschman index (HHI). The HHI is a ...


Improving Spatio-Temporal Benefit Transfers For Pest Control By Generalist Predators In Cotton In The Southwestern Us, Ruscena Wiederholt, Kenneth J. Bagstad, Gary F. Mccracken, Jay E.

Improving Spatio-Temporal Benefit Transfers For Pest Control By Generalist Predators In Cotton In The Southwestern Us, Ruscena Wiederholt, Kenneth J. Bagstad, Gary F. Mccracken, Jay E. Diffendorfer, John B. Loomis, Darius J. Semmens, Amy L. Russell, Chris Sansone, Kelsie Lasharr, Paul Cryan, Claudia Reynoso, Rodrigo A. Medellin, Laura Lopez-Hoffman

Amy L. Russell

Given rapid changes in agricultural practice, it is critical to understand how alterations in ecological, technological, and economic conditions over time and space impact ecosystem services in agroecosystems. Here, we present a benefit transfer approach to quantify cotton pest-control services provided by a generalist predator, the Mexican free-tailed bat (Tadarida brasiliensis mexicana), in the southwestern United States. We show that pest-control estimates derived using (1) a compound spatial-temporal model - which incorporates spatial and temporal variability in crop pest-control service values - are likely to exhibit less error than those derived using (2) a simple-spatial model (i.e., a model that extrapolates ...


The Role Of Fringe Benefits In Operator Off-Farm Labor Supply, Helen H. Jensen, Priscilla Salant Oct 2016

The Role Of Fringe Benefits In Operator Off-Farm Labor Supply, Helen H. Jensen, Priscilla Salant

Helen Jensen

The last thirty years have seen a major shift in the share of total compensation paid to workers in the form of nonwage fringe benefits, that is, payments in a form other than currently spendable cash (Chen). Fringe benefits have become increasingly important because they are a source of income that receives preferential tax treatment, and can often be offered at group savings, as in the case of purchase oflife and health insurance.


Combine Harvester Econometric Model With Forward Speed Optimization, Nathan E. Isaac, Graeme R. Quick, Stuart J. Birrell, William M. Edwards, Bruce A. Coers Jul 2016

Combine Harvester Econometric Model With Forward Speed Optimization, Nathan E. Isaac, Graeme R. Quick, Stuart J. Birrell, William M. Edwards, Bruce A. Coers

William Edwards

A combine harvester econometric simulation model was developed with the goal of matching the combine forward speed to the maximum harvested net income per acre. The model considers the machinery management costs of owning a combine and platform header for harvesting wheat. A statistical Design of Experiment (DOE) was used to evaluate the model using tri-level variables; the medium values constituted the model base case. Of the 27 input variables, the optimum speed was significantly influenced by the crop area, G/MOG ratio, grain unit price, field yield, field efficiency, grain moisture content, probability of a working day in the ...

Plastic Pollution And The Global Throwaway Culture: Environmental Injustices Of Single-Use Plastic, Kristin L. Mcdermott May 2016

Plastic Pollution And The Global Throwaway Culture: Environmental Injustices Of Single-Use Plastic, Kristin L. Mcdermott

ENV 434 Environmental Justice

The global throwaway culture has created a cross-ecosystem plastic pollution injustice. The first to suffer this injustice will be the most vulnerable. Our oceans have become our dumpsters. The throwaway culture has created a disrespect of material goods that has turned the earth’s resources into rubbish after a single use. Eighty percent of the yearly 8 million tons of plastic that enter the ocean is single use plastic, such as plastic bottles, plastic shopping bags, or cigarette lighters.[1] Plastic has destroyed ecosystems, robbing impoverished communities of natural resources and of a healthy and safe living environment. First to ...

Perspective Makes A Difference, Lee L. Schulz

Economics Publications

USDA’S June Hogs and Pigs Report told us where the industry is and where it may be headed. The report showed a big surge in inventories compared to the PEDV-depressed levels a year ago. But inventories aren’t that far out of line with June 2013 levels prior to PEDV.


The Economics Of Organic Dairying, Larry F. Tranel Jan 2015

The Economics Of Organic Dairying, Larry F. Tranel

Animal Industry Report

Organic dairy producers (and others who aspire to this profession) need sound economic data and analyses to make decisions. This study analyzed and evaluated the profitability of 10 organic dairies using Dairy TRANS Financial Analysis software. On average, these 10 dairies showed “good” profitability for 2013 but there was a wide range of results. It is hoped this study will assist current and aspiring organic dairy producers to both budget and benchmark their dairy operations to better plan for future profitability. Producers are also urged to consider using the Dairy TRANS Financial Analysis to analyze and further improve dairy profits ...


Impacts Of National Forests In The West On County Population And Employment, Andrew Pugliese, Laura Mccann, Georgeanne M. Artz Jan 2015

Impacts Of National Forests In The West On County Population And Employment, Andrew Pugliese, Laura Mccann, Georgeanne M. Artz

Economics Publications

This study seeks to understand the manner and extent to which western national forests influence an area's overall population and employment growth by evaluating changes in management emphasis from single to multiple uses. The Carlino and Mills model was used to examine county level data from 12 western states over the period 1977–2010. Changes in timber sales and the amount of land owned by the Forest Service were not found to be significantly related to employment growth.


Strength Of Protection For Geographical Indications: Promotion Incentives And Welfare Effects, Luisa Menapace, Giancarlo Moschini Jul 2014

Strength Of Protection For Geographical Indications: Promotion Incentives And Welfare Effects, Luisa Menapace, Giancarlo Moschini

Economics Publications

We address the question of how the strength of protection for geographical indications (GIs) affects the GI industry's promotion incentives, equilibrium market outcomes, and the distribution of welfare. Geographical indication producers engage in informative advertising by associating their true quality premium (relative to a substitute product) with a specific label emphasizing the GI's geographic origin. The extent to which the names/words of the GI label can be used and/or imitated by competing products—which depends on the strength of GI protection—determines how informative the GI promotion messages can be. Consumers’ heterogeneous preferences (vis-à-vis the GI ...

In this paper, we discuss the importance of developing integrated assessment models to support the design and implementation of policies to address water quality problems associated with agricultural pollution. We describe a new modelling system, LUMINATE, which links land use decisions made at the field scale in the Upper Mississippi, Ohio and Tennessee Basins through both environmental and hydrological components to downstream water quality effects and hypoxia in the Gulf of Mexico. This modelling system can be used to analyse detailed policy scenarios identifying the costs of the policies and their resulting benefits for improved local and regional water quality ...


Unravelling The Consumer Brain: The Role Of Emotion In Purchase Behavior, Enrique Bello Apr 2014

Unravelling The Consumer Brain: The Role Of Emotion In Purchase Behavior, Enrique Bello

Undergraduate Honors Theses

The present research used electroencephalography (EEG) measures to examine the neural mechanisms of purchase behavior. Specifically, this study examined how affective priming influences a purchase decision when brand and price are varied. Participants were presented with Yes/No purchase decision trials for 14 different grocery products- seven national brand and seven private label products- while EEG activity was recorded. Price was increased or decreased relative to a base reference price. Prior to product onset, an emotional prime was flashed. The prime was a positive, negative, or neutral image from the International Affective Picture System (IAPS). Main behavioral results showed that ...


Producing Energy While Sequestering Carbon? The Relationship Between Biochar And Agricultural Productivity, Nathan Kauffman, Jerome Dumortier, Dermot J. Hayes, Robert C. Brown, David Laird Apr 2014

Producing Energy While Sequestering Carbon? The Relationship Between Biochar And Agricultural Productivity, Nathan Kauffman, Jerome Dumortier, Dermot J. Hayes, Robert C. Brown, David Laird

Economics Publications

A partial solution to problems associated with anthropogenic greenhouse gas (GHG) emissions could be the development and deployment of carbon-negative technologies, i.e., producing energy while reducing atmospheric carbon dioxide levels. Biofuels have been considered a possibility but have faced limitations due to competition with food production and GHG emissions through indirect land-use change (ILUC). In this article, we show how emissions from ILUC can potentially be reduced by producing food and bioenergy from biochar amended soils. The possibility of yield improvements from biochar would reduce the land requirement for crop production and thus, lead to a reduction in emissions ...


Natural Phenomena As Potential Influence On Social And Political Behavior: The Earth’S Magnetic Field, Jackie R. East Jan 2014

Natural Phenomena As Potential Influence On Social And Political Behavior: The Earth’S Magnetic Field, Jackie R. East

Theses and Dissertations--Political Science

Researchers use natural phenomena in a number of disciplines to help explain human behavioral outcomes. Research regarding the potential effects of magnetic fields on animal and human behavior indicates that fields could influence outcomes of interest to social scientists. Tests so far have been limited in scope. This work is a preliminary evaluation of whether the earth’s magnetic field influences human behavior it examines the baseline relationship exhibited between geomagnetic readings and a host of social and political outcomes. The emphasis on breadth of topical coverage in these statistical trials, rather than on depth of development for any one ...


Predictable And Predictive Emotions: Explaining Cheap Signals And Trust Re-Extension, Eric Schniter, Roman M. Sheremeta Jan 2014

Predictable And Predictive Emotions: Explaining Cheap Signals And Trust Re-Extension, Eric Schniter, Roman M. Sheremeta

ESI Publications

Despite normative predictions from economics and biology, unrelated strangers will often develop the trust necessary to reap gains from one-shot economic exchange opportunities. This appears to be especially true when declared intentions and emotions can be cheaply communicated. Perhaps even more puzzling to economists and biologists is the observation that anonymous and unrelated individuals, known to have breached trust, often make effective use of cheap signals, such as promises and apologies, to encourage trust re-extension. We used a pair of trust games with one-way communication and an emotion survey to investigate the role of emotions in regulating the propensity to ...

Genetic Contamination Of Traditional Products, E. Kwan Choi Jan 2013

Genetic Contamination Of Traditional Products, E. Kwan Choi

Economics Publications

Cross-pollination can be caused by birds, insects and wind. Genetically modified (GM) seeds are produced each year in a controlled environment to maintain their purity. However, pollen from the GM crop can be transferred to traditional crops. When the GM crop producers are in long-run equilibrium and buy seeds from a monopolistic seed producer, the resulting market equilibrium is identical to that when a seed monopolist produces the GM crop directly. When involuntary genetic contamination occurs, the monopolist eventually loses its advantage and stops its protection of GM seeds. A terminator gene can stop genetic contamination but imposes spillover costs ...


Economic And Environmental Effects Of Switchgrass Production On A Representative Cow-Calf Farm In Middle Tennessee, Hanna Leah Watts May 2012

Economic And Environmental Effects Of Switchgrass Production On A Representative Cow-Calf Farm In Middle Tennessee, Hanna Leah Watts

Masters Theses

The purpose of this research was to evaluate the economic tradeoffs and land use dynamics of incorporating switchgrass into the farm plan of a representative middle Tennessee cow-calf operation. A net revenue simulation and multi-year mathematical programming model was used to find the optimum mix of switchgrass and cow-calf enterprises that will maximize whole farm net revenues over 30 years on a representative middle Tennessee beef farm under both average and above average management. Land use changes predicted by the mathematical programming model were used to assess the carbon change associated with incorporating, or transitioning to, switchgrass production.

This presentation describes rebound measurements in the US economy, the dominance of "embedded energy" (production-side energy use), and the economic costs of polices to mitigate rebound effects.


An Income-Based Analysis Of Historical Us Energy Consumption, Harry D. Saunders Apr 2011

An Income-Based Analysis Of Historical Us Energy Consumption, Harry D. Saunders

Harry D. Saunders

This paper introduces a new decomposition of energy consumption to reveal the effects of consumer income levels on energy use. It concludes that the great bulk of energy consumption in the US is embedded in goods and services purchased by consumers and that this component of energy demand is growing more rapidly than direct use of energy by households owing to the preferences of high-income consumers. Significantly, this embedded component of energy demand has historically experienced large rebound magnitudes. The analysis also concludes that energy consumption is driven by more than just income level, with the lowest-income consumers using more ...

Growing Farmers’ Markets: Measuring The Competitiveness Of The Byron Farmers’ Market With Other Local Food Sources, Audrey Gross

Independent Study Project (ISP) Collection

Farmers’ markets are growing across the world at an exponential rate. However, there is little research that challenges the competitiveness of these farmers’ markets in competing with other food distribution locations, including supermarkets and local food stores. The following report focuses on using the principles of perfect competition to evaluate the competitiveness of the Byron Farmers’ Market with other local food sources in Byron Bay, NSW.

Data was collected through 120 consumer surveys (60 from the Farmers’ Market, 30 from Woolworths, and 30 from local food stores: Santos, Fundamentals, and Green Garage), 31 stallholder surveys from the Farmers’ Market, price ...
