Young people in Japan contend with shifting understandings of family and friends, insecure jobs, and changing frames around global and national identities. The category of youth itself is unsettled amid a long period of social and economic change and perceived widely as crisis. Within contested social categories of youth, how do young Japanese people use the city, media, and body practices to create flexible, meaningful sociality across spaces of work, education, and play? What do youthful sociality and practices reveal about globally oriented connections and how do they inform conceptions of the future, kinship, gender, and pluralized identities? In short, what is the embodied and affective experience of being young as the category itself is increasingly unstable and full of risks? These questions shape the contours of this project.

This dissertation considers youth through its becoming, that is, the lived enactment of youth as energy, emotion, and sensibility always in motion and within range of cultural, spatial, bodily, and technological forces. Three groups of young people in this layered latitudinal study demonstrate various relations to the city street, visual media, globalized identities, contingent work within affect and cultural production, and education. The three groups are distinctly different but share surprising points of connection.

I lived alongside these three groups to understand the ways young people are innovating within the shifting form of youth. I skated with male skateboarders in their teens to early 30s who created Japan's most influential skate company; I taught kids attending a specialized cram school for kikokushijo (children who have lived abroad due to a parent's job assignment); I observed and hung out with young creative workers, the photographers, web designers, and graphic artists who produce the visual and textual content and relationships composing commercial "youth culture."

My project examines how these young people redefine youth through bodily practices, identities, and economic de/attachments. The skaters' embodied actions distribute/dissipate their energies in risky ways outside formal structures of labor. The kikokushijo children, with their bi-cultural fluency produced in circuits of capitalist labor, offer a desirable image of a flexible Japanese future while their heterogeneous identities appear threatening in the present. The creative workers are precariously positioned as "affective labor" within transglobal (youth) cultural production, working to generate visual and textual content constant stressful uncertainties. All three groups share uneasy ground with capitalist practices, risky social identities, and crucially, intimate relations with city space. In attending to their practices through ethnographic participation and video, this dissertation explores questions concerning youthful relations to space produced in material contacts, remembered geographies of other places and imaginary urban sites.

The dissertation itself is electronic and non-linear; a formal enactment of the drifting contact between forms of youth. It opens up to lines of connection between questions, sites, events, and bodies and attempts an unfolding of affect, imagination, and experience to tell stories about histories of gender and labor, city life, and global dreams. It asks if the globalized forms of Japanese youth avoid the risks of the impossible secure for the open possibilities of becoming and thus refuse containment by crisis?

In the first chapter of this dissertation I develop a flexible and estimable equilibrium model that jointly considers location decisions of heterogeneous agents across space, and their optimal portfolio decisions. Merging continuous-time asset pricing with urban economics models, I find a unique sorting equilibrium and derive equilibrium house and asset prices in closed-form. Risk premia for homes depend on both aggregate and local idiosyncratic risks, and equilibrium returns for stocks depend on their correlation with city specific income and house price risk. In equilibrium, very risk-averse households do not locate in risky cities although they may have a high productivity match with those cities. I estimate a version of this model using house price and wage data at the metropolitan area level and provide estimates for risk premia for different cities. The estimated risk premia imply that homes are on average about 20000 cheaper than they would be if owners were risk-neutral. This estimate is over 100000 for volatile coastal cities. I simulate the model to study the effects of financial innovation on equilibrium outcomes. For reasonable parameters, creating assets that correlate with city-specific risks increase house prices by about 20% and productivity by about 10%. The average willingness to pay for completing markets per homeowner is between $10000 and $20000. Productivity is increased due to a unique channel: lowering the amount of non-insurable risk decreases the households' incentive to sort on these risks, which leads to a more efficient allocation of human capital in the economy.

The second chapter of this dissertation studies ability signaling in a model of employer learning and statistical discrimination. In traditional signaling models, education provides a way for individuals to sort themselves by ability. Employers in turn use education to statistically discriminate, paying wages that reflect the average productivity of workers with the same given level of education. In this chapter, we provide evidence that graduating from college plays a much more direct role in revealing ability to the labor market. Using the NLSY79, our results suggest that ability is observed nearly perfectly for college graduates. In contrast, returns to AFQT for high school graduates are initially very close to zero and rise steeply with experience. As a result, from very beginning of the career, college graduates are paid in accordance with their own ability, while the wages of high school graduates are initially unrelated to their own ability. This view of ability revelation in the labor market has considerable power in explaining racial differences in wages, education, and the returns to ability. In particular, we find a 6-10 percent wage penalty for blacks (conditional on ability) in the high school market but a small positive black wage premium in the college labor market. These results are consistent with the notion that employers use race to statistically discriminate in the high school market but have no need to do so in the college market.

Methane is an important greenhouse gas, and an ideal target for greenhouse gas emissions reductions. Unlike carbon dioxide, methane has a relatively short atmospheric lifetime, so reductions in methane emissions could have large and immediate impacts on anthropogenic radiative forcing. A more detailed understanding of the global methane budget could help guide effective emissions reductions efforts.

Humans have greatly altered the methane budget. Anthropogenic methane sources are approximately equal in flux to natural sources, and the current atmospheric methane concentration is ~2.5 times pre-industrial levels. The advent of hydraulic fracturing and resulting increase in unconventional natural gas extraction have introduced new uncertainties in the methane budget. At the same time, the next few decades could be a crucial period for controlling greenhouse gas emissions to avoid irreversible and catastrophic changes in global climate. Natural gas could provide lower-carbon fossil energy, but the climate benefits of this fuel source are highly dependent on the associated methane emissions. In this context of increasing uncertainty and growing necessity, quantifying the impact of natural gas extraction and use on the methane budget is an essential step in making informed decisions about energy.

In the work presented here, I track methane in the environment to address several areas of uncertainty in our present understanding of the methane budget. I apply the tools of methane analysis in a variety of environments, from rural groundwater supplies to an urban atmosphere, and at a range of scales, from individual point sources to regional flux. I first show that carbon isotopes of methane and co-occurrence of ethane are useful techniques for differentiating a range of methane sources. In so doing, I also show that leaks from natural gas infrastructure are a major source of methane in my study area, Boston, MA. I then build on this work by applying the same methane carbon isotope and ethane signatures to partition methane flux for the Boston metro region. I find that 88% of the methane enhancement in the atmosphere above Boston is due to pipeline natural gas.

In the final portion of this thesis and the two appendices, I move from the distribution side of the natural gas production chain to extraction, specifically addressing the potential impacts from hydraulic fracturing in my home state of North Carolina. I combine the methane source identification techniques of the previous sections with additional geochemical analyses to document the pre-drilling water quality in the Deep River Triassic Basin, an area which could be drilled for natural gas in the future. This data set is unique in that North Carolina has no pre-existing commercial oil and gas extraction, unlike other states where unconventional gas extraction is currently taking place. This research is, to my knowledge, the first to examine the hydrogeology of the Deep River Basin, in addition to providing an important background data set that could be used to track changes in water quality accompanying hydraulic fracturing in the region in the future.

This dissertation focuses on the experiences of children who work the streets of Lima primarily as jugglers, musicians, and candy vendors. I explore how children's everyday lives are marked not only by the hardships typically associated with poverty, but also by their need to respond to the dominant notions of childhood, family roles, and urban order that make them into symbols of underdevelopment. In particular, I argue that transnational discourses about the perniciousness of child labor, articulated through development agencies, NGOs, the Peruvian state, the media, and everyday interpersonal exchanges, perpetuate an idea of childhood that not only fails to correspond to the realities of the children that I came to know, but that reinscribes a view of them and their families as impediments to progress and thus available for diverse forms of moral intervention. I ground my analysis in a notion that I call "public childhoods." This concept draws attention to the ways that subjectivities form through intersecting mechanisms of power, in this sense capturing nuances that common terms such as "street children" and "child laborer" gloss over. Children, I show, are a symbolic site for the articulation of the kinds of classed, raced and gendered differences that characterize Lima's contemporary urban imaginary. As they bear the embodied effects of such discourses, I argue, children who work the streets also participate - if in subtle ways - in these everyday ideological struggles into which they are drawn.

My dissertation is based on twenty-two months of fieldwork in Peru, in addition to several one- and two-month periods of preliminary and follow-up research. As an ethnographer, my research consisted primarily of accompanying children as they went about their daily routines. Beyond "hanging out" in their workspaces, which included a busy traffic intersection in an upper-middle class district and public buses, I also spent a great deal of time with the children's families, typically in their homes in Lima's shantytowns and working-class neighborhoods. I also attended meetings and otherwise participated in institutional spaces such as NGOs, social movements, Congressional hearings, and advocacy groups. Finally, in order to gain a more long-term perspective on discussions and policies involving childhood, I conducted research in Lima's historical archives.

Literary scholars have long identified a formal correspondence between city and novel. In the late nineteenth and early twentieth centuries, the city became embedded in the narrative forms of fiction as the latter attempted to map the coordinates of the rapidly expanding and increasingly complex social formations the former produced. In our moment, the older idea of the “city” as a discrete, identifiable form of human settlement is almost universally theorized as having been displaced by what is variously called “the metropolis”, “city everywhere”, or “planetary urbanization”. Without any outside to its parameters, how can the idea of the city still have meaning? This dissertation explores how the contemporary city novel can illuminate the bewildering new spaces in which we live and the seemingly inevitable "becoming-planetary" of the urban.

This dissertation is a social history of the city of Detroit in the 1970s. Using archives official and unofficial - oral histories and archived document collections, self-published memoirs and legal documents, personal papers and the newspapers of the radical press - it portrays a city in flux. It was in the 1970s that the urban crisis in the cities of the United States crested. Detroit, as had been the case throughout the twentieth century, was at the forefront of these changes. This dissertation demonstrates the local social, political, and economic circumstances that contributed to the dramatic increase in prison populations since the 1970s with a focus on the halls of government, the courtroom, and city streets. In the streets, unemployed African American youth organized themselves to counteract the contracted social distribution allocated to them under rapidly changing economic circumstances. They organized themselves for creative expression, protection and solidarity in a hostile city, and to pursue economic endeavors in the informal economy. They sometimes committed crimes. In the courts, Wayne County Juvenile Court Judge James Lincoln, a liberal Democrat long allied with New Deal political alliances, became disenchanted with rehabilitative solutions to juvenile delinquency and embraced more punitive measures, namely incarceration. In city hall, Coleman Young, the city's first African American mayor, confronted this crisis with a form of policing that concentrated predominately on the city's unemployed African American youth, and the result was the criminalization of poverty and race we have come to understand as mass incarceration.
