Item Open Access Assessing Africa-Wide Pangolin Exploitation by Scaling Local Data(Conservation Letters, 2018-03) Ingram, DJ; Coad, L; Abernethy, KA; Maisels, F; Stokes, EJ; Bobo, KS; Breuer, T; Gandiwa, E; Ghiurghi, A; Greengrass, E; Holmern, T; Kamgaing, TOW; Ndong Obiang, AM; Poulsen, JR; Schleicher, J; Nielsen, MR; Solly, H; Vath, CL; Waltert, M; Whitham, CEL; Wilkie, DS; Scharlemann, JPWCopyright and Photocopying: © 2017 The Authors. Conservation Letters published by Wiley Periodicals, Inc. Overexploitation is one of the main pressures driving wildlife closer to extinction, yet broad-scale data to evaluate species’ declines are limited. Using African pangolins (Family: Pholidota) as a case study, we demonstrate that collating local-scale data can provide crucial information on regional trends in exploitation of threatened species to inform conservation actions and policy. We estimate that 0.4-2.7 million pangolins are hunted annually in Central African forests. The number of pangolins hunted has increased by ∼150% and the proportion of pangolins of all vertebrates hunted increased from 0.04% to 1.83% over the past four decades. However, there were no trends in pangolins observed at markets, suggesting use of alternative supply chains. The price of giant (Smutsia gigantea) and arboreal (Phataginus sp.) pangolins in urban markets has increased 5.8 and 2.3 times respectively, mirroring trends in Asian pangolins. Efforts and resources are needed to increase law enforcement and population monitoring, and investigate linkages between subsistence hunting and illegal wildlife trade.Item Open Access How Do Gasoline Prices Affect Fleet Fuel Economy?(2009) Timmins, CD; Li, S; von Haefen, RExploiting a rich dataset of passenger vehicle registrations in 20 US MSAs from 1997 to 2005, we examine the effects of gasoline prices on the automotive fleet's composition. We find that high gasoline prices affect fleet fuel economy through two channels: shifting new auto purchases towards more fuel-efficient vehicles, and speeding the scrappage of older, less fuel-efficient used vehicles. Policy simulations suggest that a 10 percent increase in gasoline prices from 2005 levels will generate a 0.22 percent increase in fleet fuel economy in the short run and a 2.04 percent increase in the long run.Item Open Access Private Landowner Participation in the Carbon Market: Opportunities in North Carolina(2008-04-21T21:24:48Z) Gray, ErinIn response to the growing awareness of climate change across the globe, innovative conservationists have begun employing market approaches to capture the true value of carbon emissions and encourage sequestration. The most widespread mechanism used to date, both domestically and internationally, is the carbon cap-and-trade system. The US carbon market is currently highly fragmented and mostly voluntary, but the growth of state actions, business participation, and growth in climate change market proposals in the 110th Congress all suggest that the US is headed towards a regulated carbon cap-and-trade system. Beyond reducing carbon emissions from sources, the market has the potential to promote conservation efforts and sustainable land-use practices on private lands by providing an additional revenue stream to private landowners. Without regulations, however, there are several barriers to entry that are preventing private landowner participation. These include: a lack of information of entry opportunities and characteristics of cap-and-trade proposals in the 110th Congress, cost constraints due to low market prices prevalent in US carbon markets, concerns about carbon market eligibility with other conservation funding programs, and concerns about entering into long-term conservation contracts required by market schemes to ensure permanence of sequestration activities. This report examines these barriers through 1) a scoping analysis of international and domestic carbon markets to determine North Carolina private landowner entry opportunities, 2) an assessment of eligibility criteria for relevant Federal and state conservation funding and other ecosystem service markets, and 3) an economic analysis of representative NC properties to determine income potential from carbon activities. Carbon market participation is shown to be a worthwhile endeavor for conservation-minded landowners. The modeled gains in income demonstrate a low but positive income gain if carbon market prices are to stay constant at the Chicago Climate Exchange’s current credit price of $2.05 per metric ton of CO2 equivalent. Using predictions from recent studies that have modeled trading price increases with cap-and-trade proposals in the 110th Congress, landowner gain is shown to sharply increase over a fifty year time horizon with a regulated carbon market. This study is useful for the North Carolina land protection community in encouraging private landowner participation in the carbon market. Policy recommendations are also provided to assist the state of North Carolina in moving forward with carbon market participation.Item Open Access Qualities or Inequalities?: How Gender Shapes Value in the Market for Contemporary Art(2021) Brown, Taylor WhittenHow does gender inequality persist in the art world today? Or, more generally, what role do social characteristics like gender play in markets for cultural goods, such as art? That is the focus of this research. Using a novel dataset of 255,887 contemporary artworks produced by 18,624 artists and gleaned from an online marketplace, I employ the case of gender in the art world to investigate how social characteristics of producers can impact market outcomes and structures. Although there is prominent scholarship on product markets and inequality within sociology, questions such as these are rarely posed. Work generally focuses on the quality of goods and on the status of producing organizations, without attention to individual producer characteristics, including gender.The first study of this dissertation implements machine learning classification to examine whether female and male artists produce artworks with different characteristics. These analyses rely on a taxonomy of over 1,000 art-relevant features, coded by a team of art historians, to describe the disciplines, physical attributes, styles and periods, object types, and settings of each artwork in the dataset. I find that artworks by women and men do not substantively differ on the majority of aesthetic, conceptual, or material features that they depict. While some, less common, features of art appear more in work by women or men, by in large these two groups of producers do not bring different products to the art market. Studies two and three of this dissertation move to address alternative hypotheses for disparity in the economic outcomes of women and men in the contemporary art market. With mixed effect regression, I test whether artworks by women are priced differently than artworks by men, even after accounting for the categories and features they depict. I find that art by women is listed at a discount of approximately 10 to 12 percent relative to art by men. I also find that, of those art qualities that differ in use between women and men, qualities of art predominantly made by women are valued less than those predominantly made by men, net of who creates them. In combination, these findings echo and extend calls to value the labor of women and men comparably. They also broaden our understanding of the potential for social status characteristics, like gender, to act as organizing structures in the production, meaning, and valuation of markets.
