Description
South Mountain is the largest municipal park in the nation. It is a bundled amenity, providing a series of linked services to the surrounding communities. A dataset of 19,209 homes in 155 neighborhoods within three miles of the park was utilized in order to complete a hedonic estimation for two nearby urban villages, Ahwatukee Foothills and South Mountain Village. Measures of access include proximity to the park, trailhead access, and adjacency to the park. Two regressions were estimated, the first including lot characteristics and subdivision fixed effects and the second using the coefficients for each subdivision as the dependent variable. These estimates describe how the location of a house in a subdivision contributes to its conditional mean price. As a result they offer a direct basis for capturing amenities measured at the neighborhood scale on home values. Park proximity, trailhead access and adjacency were found to significantly influence the price of homes at the 5% confidence level in Ahwatukee, but not in South Mountain Village. The results of this study can be applied to issues of environmental justice and park access in determining which areas and attributes of the park are associated with a high premium. Though South Mountain was preserved some time ago, development and future preservation in the City of Phoenix can be informed by such studies.

There is growing public concern about the implications of climate change for natural processes, such as the melting of ice at the poles, but less clear are the implications for food production. Famine and conflict have a long and complicated history, made increasingly complicated by the intricate global food system. In this paper, I explore the effect of increasingly severe El Niño Southern Oscillation cycles on conflict in an effort to determine how abnormal climate patterns affect food security and, indirectly, conflict. I use a non-linear probit model to analyze the relationship between several binary conflict variables and food supply.

Description
Campaign finance regulation has drastically changed since the founding of the Republic. Originally, few laws regulated how much could be contributed to political campaigns and who could make contributions. One by one, Congress passed laws to limit the possibility of corruption, for example by banning the solicitation of federal workers and banning contributions from corporations. As the United States moved into the 20th Century, regulations became more robust with more accountability. The modern structure of campaign finance regulation was established in the 1970's with legislation like the Federal Election Campaign Act and with Supreme Court rulings like in Buckley v. Valeo. Since then, the Court has moved increasingly to strike down campaign finance laws they see as limiting to First Amendment free speech. However, Arizona is one of a handful of states that established a system of publicly financed campaigns at the state-wide and legislative level. Passed in 1998, Proposition 200 attempted to limit the influence of money politics. For my research I hypothesized that a public financing system like the Arizona Citizens Clean Elections Commission (CCEC) would lead to Democrats running with public funds more than Republicans, women running clean more than men, and rural candidates running clean more than urban ones, and that Democrats, women, and rural candidates would win in higher proportions than than if they ran a traditional campaign. After compiling data from the CCEC and the National Institute on Money in State Politics, I found that Democrats do run with public funds in statistically higher proportions than Republicans, but when they do they lose in higher proportions than Democrats who run traditionally. Female candidates only ran at a statistically higher proportion from 2002 to 2008, after which the difference was not statistically significant. For all year ranges women who ran with public money lost in higher proportions than women who ran traditionally. Similarly, rural candidates only ran at a statistically higher proportion from 2002 to 2008. However, they only lost at higher proportions from 2002 to 2008 instead of the whole range like with women and Democratic candidates.

Description
We examine the bias resulting from temporal and spatial aggregation of weather variables in environmental economics. In order to include temporally and/or spatially continuous environmental variables (such as temperature and precipitation), many studies discritize them. The finer the scale of discrization chosen, the more difficult it can be to obtain a complete and reliable data set. Studies performed at very fine scales often find tighter and more dramatic relationships between variables such as temperature and income per capita. We examine this question by repeating the same empirical study at various temporal and spatial scales and comparing the resulting parameter estimates.

Description
Mining is a key component of both the Brazilian and Chilean economies and accounts for an outsized share of these countries’ exports. Yet, it is a common target for environmental criticism, especially due to its impacts on local populations and ecosystems. Brazil and Chile have adopted markedly different trade strategies over the past three decades, most notably with regards to their involvement in international trade agreements. This paper investigates how these differences in trade policy since 1990 have affected the sustainability of each country’s mining sector by identifying and comparing the channels through which free trade agreements influence the environmental impacts of resource extraction.

Description
This thesis conducted an evaluation of the performance and return on investment of a 2 x 6m, simple design greenhouse, as a climate control technology. Specifically, differences in internal microclimate conditions between a greenhouse treatment plot, and sun and shaded control plots were assessed and related to observed differences in crop yields across these plots. Growing conditions and productivity of two crops, tomato and swiss chard, which were grown over summer and winter growing seasons, respectively, were compared. It was found that the greenhouse was associated with improved growth conditions (as measured by the R-Index) for both crops but resulted in higher productivity only for tomatoes. Return on investment and food security impacts from the scaling of greenhouse agriculture were also explored.
