A Site-Portfolio Model For Multiple-Destination Recreation Trips: Valuing Trips To National Parks In The Southwestern Usa, George Parsons 2016 Selected Works

A Site-Portfolio Model For Multiple-Destination Recreation Trips: Valuing Trips To National Parks In The Southwestern Usa, George Parsons

George R. Parsons

We propose a new method for analyzing multiple-destination recreation trips and apply it to visitation at national parks in the southwestern United States including well-known parks such as the Grand Canyon and Zion. We use conventional random utility theory and treat groups of parks (portfolios) as choice alternatives. We consider one choice occasion per respondent and condition that choice on the person visiting at least one park in the choice set, so the participation decision (go/no-go) is not modeled. Trip cost includes time, travel, lodging and food cost for visiting all sites in the portfolio. Variation in trip cost ...

The Real Footprint Of Electric Vehicles, And What That Could Mean For Our Future, Krista Brown 2016 Colby College

The Real Footprint Of Electric Vehicles, And What That Could Mean For Our Future, Krista Brown

Journal of Environmental and Resource Economics at Colby

This paper looks at the impact of electric vehicles on CO2 emissions specifically based on the type of electricity used in each New England state analyzed. The research looks at the question of whether or not emissions will in fact be lowered as electric cars start to take the majority of vehicles used instead of the conventional cars that take up a much larger percent of the motor vehicles used today. Taking into account the use of electricity and how many sources of electricity also release a substantial amount of emissions, we see how valid the public opinion of electric ...

The Effect Of The Deer Population On The Number Of Car Accidents, Timothy J. Hallock Jr

Journal of Environmental and Resource Economics at Colby

This paper examines the relationship between the deer population and the number of car accidents in New York State from 2002-2012. Data collected includes information on the amount of deer hunted, the number of car accidents, and the number of hunting permits issued. This paper also involves a county level analysis within New York State of 56 counties from 2007 - 2012. An important part of analysis of this paper is the examination of the Buck population vs. the Doe population on the number of car accidents. This is an important study because of its possible policy implications regarding the amount ...


The Effect Of Information On Avoidance Behavior And Bicycle Transportation: A Study Of “Spare The Air” And Bay Area Bikeshare, Paige W. Whistler 2016 Colby College

The Effect Of Information On Avoidance Behavior And Bicycle Transportation: A Study Of “Spare The Air” And Bay Area Bikeshare, Paige W. Whistler

Journal of Environmental and Resource Economics at Colby

This paper seeks to address the effect of “Spare the Air” pollution control alerts in the San Francisco Bay Area in California on the use of Bay Area BikeShare as a form of transportation. By observing the daily alerts on the duration of rides using BikeShare, this paper observes if STA ozone alerts are effective in changing human behavior. The results show that only as a subscriber to the BikeShare program and on an alert day does duration decrease whereas customers regardless of if it is an alert day will ride more often and at longer distances. The results contradict ...


Socioeconomic Attributes’ Relationship To Green Commercial Office Buildings, Tianyang Zhou 2016 Colby College

Socioeconomic Attributes’ Relationship To Green Commercial Office Buildings, Tianyang Zhou

Journal of Environmental and Resource Economics at Colby

This paper examines the relationship between the socioeconomic attributes of a state and its green commercial office space adaptation. I hypothesize that a state with high socioeconomic status will have a high green building adoption. Additionally, the high socioeconomic status states may be more likely to invest in green commercial buildings with higher LEED certification levels, and various types of LEED commericial office projects are affected by the socoeconomic attributes differently.


Who Cares About The Environment? A Study Of Environmental Behavior In Maine, Chandler L. Blake 2016 Colby College

Who Cares About The Environment? A Study Of Environmental Behavior In Maine, Chandler L. Blake

Journal of Environmental and Resource Economics at Colby

Identifying and targeting environmentally minded people is crucial to making any environmental campaign successful. It allows you to advertise to the people who will be the most helpful and supportive to your cause. The goal of this study is to identify the general demographics of environmentally minded people. To do this I examine voting data through each county in Maine and run a regression to test whether income, education level, and household size have any correlation to how the county votes on environmental issues. I found that the higher a county’s income, the more environmentally friendly their voting. I ...


Do Peers Get Punished: Stock Market Effect Of Bp Oil Spill On Peers, Yuga Koda 2016 Colby College

Do Peers Get Punished: Stock Market Effect Of Bp Oil Spill On Peers, Yuga Koda

Journal of Environmental and Resource Economics at Colby

This paper examines the stock market reaction to the British Petroleum oil spill on April 20, 2010. This event study looks at different sectors that may be affected by the oil spill. It finds that different industries do not have significant abnormal returns, with two exceptions. First, utilities companies have a very small positive abnormal return for a short period of time after the incident. Second, when only looking at BP's direct competitors, there is a statistically significant negative abnormal return, implying that BP's competitors are punished for BP's mishap.


Media Effects On Solar Panel Installations Across 20 States, Casey Romeo 2016 Colby College

Media Effects On Solar Panel Installations Across 20 States, Casey Romeo

Journal of Environmental and Resource Economics at Colby

This paper looks at the relationship between media coverage of solar power and the solar panel installation at a state level. Specifically, it aims to find if more newspaper articles cause more households to adopt solar energy. Use data from 20 states from 2009 to 2014. I find that there is a modest, yet positive and statistically significant relationship between newspaper articles and installations, which suggests that the media does influence the decision to install solar panels. There is possible endogeneity between these two variables. Disentangling this endogeneity is beyond the scope of this research and would be a topic ...


Renewable Energy Consumption: Initiatives In Colorado And Washington, Robin K. Doroff 2016 Colby College

Renewable Energy Consumption: Initiatives In Colorado And Washington, Robin K. Doroff

Journal of Environmental and Resource Economics at Colby

This paper examines the use of policy mechanisms to increase renewable energy consumption within the United States. In order to effectively measure the change of renewable energy consumption, I analyze two initiatives that promote energy consumption from renewable sources and overall increases in energy conservation. Colorado and Washington had approved initiatives in the years 2004 and 2006, respectively. Although the results are not entirely statistically significant, I find that the initiatives lead to increases in total renewable energy consumption and decreases in total energy use.

Stock Market Reactions To The Iarc Announcement Linking Red Meat And Processed Meat To Cancer, Scott B. Lehman

Journal of Environmental and Resource Economics at Colby

This study investigates how food companies were affected by the International Agency for Research on Cancer’s report that linked processed meat and red meat consumption to increased risk of cancer. The results indicate that neither fast food companies nor meat producers were greatly affected by the announcement in the days immediately following the release.


Who Wants The Right To Know? An Analysis Of Gmo-Labeling In California, Sylvia M. Xu 2016 Colby College

Who Wants The Right To Know? An Analysis Of Gmo-Labeling In California, Sylvia M. Xu

Journal of Environmental and Resource Economics at Colby

There are many studies that have been done to examine what types of voting behavior or patterns are present when voting for environmental ballot measures. This paper examines what characteristics of people are likely to cause them to support Proposition 37 in California, an initiative that, if passed, would require GMO-labeling on all genetically modified foods. Using voting data at a zip code level, I use OLS regression to identify specifically what type of political party, education, occupation, household status, and income levels are more likely to support the bill. I also run weighted regressions by population and number of ...


The Effectiveness Of The Colby College Electricity Competition On Promoting Electricity Conservation To Students, Jeff Vaz 2016 Colby College

The Effectiveness Of The Colby College Electricity Competition On Promoting Electricity Conservation To Students, Jeff Vaz

Journal of Environmental and Resource Economics at Colby

This paper examines the effectiveness of the Colby College electricity reduction competition in altering students’ behavior to conserve electricity. The Colby College electricity reduction competition is an information-based policy that Colby implemented to promote the conservation of electricity, which are a major contributor to greenhouse gas (GHG) emissions in the United States. The study analyzes if different residence halls reduce electricity consumption by different amounts during the competition period. Results indicate that only 4 of 22 residence halls reduced electricity usage during competition periods in a statistically significant manner. The study concludes that the electricity competition at Colby College is ...

Milk In The Data: Food Security Impacts From A Livestock Field Experiment In Zambia, Margaret Jodlowski, Alex Winter-Nelson, Kathy Baylis, Peter Goldsmith 2016 Cornell University

Milk In The Data: Food Security Impacts From A Livestock Field Experiment In Zambia, Margaret Jodlowski, Alex Winter-Nelson, Kathy Baylis, Peter Goldsmith

Kathy Baylis

Smallholder livestock ownership has potential to enhance food security by raising incomes of the poor and by increasing the availability of nutrient-dense foods. This paper exploits the staggered rollout of livestock distribution by Heifer International in Zambia to identify the effects of livestock using statistically similar treatment and control groups in a balanced panel of households. Results indicate that livestock ownership improves dietary diversity through both direct consumption of animal products produced on farm and through increased consumption expenditures. Further results indicate that expanded livestock ownership alters the local food economy to influence food consumption by households lacking farm animals.


Subfield Profitability Analysis Reveals An Economic Case For Cropland Diversification, Elke Brandes, Gabriel S. McNunn, Lisa A. Schulte, Ian J. Bonner, David J. Muth Jr., Bruce A. Babcock, Bhavna Sharma, Emily A. Heaton 2016 Iowa State University

Subfield Profitability Analysis Reveals An Economic Case For Cropland Diversification, Elke Brandes, Gabriel S. Mcnunn, Lisa A. Schulte, Ian J. Bonner, David J. Muth Jr., Bruce A. Babcock, Bhavna Sharma, Emily A. Heaton

Agronomy Publications

Public agencies and private enterprises increasingly desire to achieve ecosystem service outcomes in agricultural systems, but are limited by perceived conflicts between economic and ecosystem service goals and a lack of tools enabling effective operational management. Here we use Iowa—an agriculturally homogeneous state representative of the Maize Belt—to demonstrate an economic rationale for cropland diversification at the subfield scale. We used a novel computational framework that integrates disparate but publicly available data to map ~3.3 million unique potential management polygons (9.3 Mha) and reveal subfield opportunities to increase overall field profitability. We analyzed subfield profitability for ...


Food Policy: Urban Farming As A Supplemental Food Source, Bessie DiDomenica, Mark Gordon 2016 Walden University

Food Policy: Urban Farming As A Supplemental Food Source, Bessie Didomenica, Mark Gordon

Journal of Social Change

Food policy has a unique role for public, nonprofit, private, and academic stakeholders. Growing food in the city is a challenge worldwide. Food systems can be destroyed by external (weather extremes) and internal (zoning regulations) forces. This study explores urban farms as a secondary food source and their common themes across four sectors. A Northeastern U.S. city was the case study to examine how it implemented its formal urban agriculture program. The positive social change implications of urban farms include greater food visibility and food access in low-income areas and more consumer awareness about growing fresh food. This study ...
