Description
Urban areas across the Unites States are facing a housing affordability crisis. One approach some cities and states have taken is to reduce or eliminate single-family zoning. Single-family zoning prevents the construction of more-affordable apartments in vast swaths of the American urban landscape. This policy shift has already occurred in Minneapolis, Sacramento, and Oregon, and is under discussion in California, Massachusetts, and North Carolina, among others. Independent of any effects on housing affordability, changes to land use will have effects on transport. I evaluate these effects using a microsimulation framework. In order for land use policies to have an effect on transport, they need to first have an effect on land use, so I first build an economic model to simulate where development will occur given a loosening of single-family zoning. Transport outcomes will vary depending on which households live in which parts of the region, so I use an equilibrium sorting model to forecast how residents will re-sort across the region in response to the land use changes induced by new land-use policies. This model also jointly forecasts how many vehicles each household will choose to own. Finally, I apply an activity-based travel demand microsimulation model to forecast the changes in transport associated with the forecast changes from the previous models. I find that while there is opportunity for economically-feasible redevelopment of single-family homes into multifamily structures, the amount of redevelopment that will occur varies greatly depending on the exact expectations of developers about future market conditions. Redevelopment is focused in higher-income neighborhoods. The transport effects of the redevelopment are minimal. Average car ownership across the region does not change hardly at all, although residents of new housing units do have somewhat lower car ownership. Vehicles kilometers traveled, mode choice, and congestion change very little as well. This does not mean that upzoning does not affect transport in general, but that more nuanced proposals may be necessary to promote desirable transport outcomes. Alternatively, the results suggest that upzoning will not worsen transport outcomes, promising for those who support upzoning on affordability grounds.

Description
There are many historical inequities regarding housing in the United States, such as the lack of access to affordable and secure housing for people of color, which is a result of centuries of exclusion. These problems remain ineffectively addressed or unaddressed by policy. Indeed, many community-based organizations report that housing policies fail to address the needs of the people—especially those in marginalized communities. Top-down approaches are efficient and more broadly applicable but miss important community-specific problems. Meanwhile, bottom-up approaches excel in highlighting community perspectives and the lived experiences of residents, but they are challenging to generalize across jurisdictions. This thesis captures community-based understandings of policy through in-depth interviews with community-based organizations (CBOs) and applies these understandings to develop a new quantitative framework for evaluating the strengths and weaknesses of housing policies that can be applied across the United States. The thesis also explores various housing policies through a multi-dimensional, intersectional, and forward-thinking analysis that centers marginalized communities.

Description
Being on the frontline of China’s ambition to internalize hi-tech supply chains (e.g., “Made in China 2025” campaign) and on the cusp of global tech competition (e.g., U.S.-China tensions), much strategic significance is given to the electronics hardware innovation cluster in Shenzhen, better known as “the world’s hardware capital”. This study investigates the latest dynamics of Shenzhen’s electronics cluster from the perspectives of agglomeration, institutions, and the built environment. The study found that despite different interpretations of the trade-off between agglomeration economies and diseconomies by both firms and analysts, increasingly diverse types of firms and intra-firm functions spillout from Shenzhen to surrounding areas, such as Dongguan and Huizhou in the Greater Bay Area. Institutionally the dissertation found that recent major external context changes, namely the pandemic, trade war, and financial and property economy fever, have not significantly changed the innovation culture in Shenzhen. As for the built environment dimension, in the context of policy thrusts, market forces, and stakeholder interests, gentrification of affordable rental housing in urban villages only happens in a modest way, without significant displacement of labor forces serving Shenzhen’s electronics industry. Policy implications include: (i) More administrative and planning co-operation should occur between Shenzhen and surrounding municipalities, given the increasingly diverse types of firms and intra-firm functions spilling out from Shenzhen; (ii) For local government, cultivating innovation culture in a cluster is a long-term task, which requires persistent building of a favorable policy environment for many years; (iii) In terms of built environment policy-making in innovation clusters (both living and working environments), more attention should be paid to implementation mechanisms; (iv) Areas surrounding Shenzhen, potentially the future spatial focus for Shenzhen’s future innovation, should be of higher policy significance. Theoretical insights include: (i) Better understanding of mechanisms underlying the spatial growth of clusters at the sub-regional scale; (ii) The importance of the long-term in the formation of cluster institutions and culture, even in the face of short-term strong context changes; (iii) The built environment is both a driver and product of industrial clustering; (iv) Integrated study of the agglomeration, institutional, and built environment dimensions of cluster dynamics will yield new insights.

Description
Sustainability has become an increasingly important field over the past few decades, especially in relation to the field of urban planning and development. Sustainable communities play a pivotal role in balancing residents' current and future needs while nurturing diversity within the community. Elements such as economic diversity, mixed land use, walkability, green spaces, varying age groups, and efficient resource and service provision cultivate sustainable communities that encourage residents to age in place. Urban planning is focused on promoting the presence of these elements in communities, but the process of turning them into reality is often difficult due to existing infrastructure, lack of resources, and failure to receive government approval. When communities fail to provide residents with the facilities necessary to foster sustainability, instability often follows as residents do not favor aging in place in communities that do not meet their current needs or will not meet their future needs. Accessory dwelling units have emerged as a strategy for encouraging and allowing aging in place to occur in the United States. Some states have legalized the development of these units to increase urban density and to provide affordable housing options in cities where residents might not be able to afford other options. Accessory dwelling units are a potential solution to address the housing affordability crisis in Hawaii by encouraging aging in place and supporting multigenerational families. Encouraging aging in place allows Hawaiian communities to become more sustainable by supporting multiple generations. Hawaii is one of the states that have legalized accessory dwelling units to address issues in the state housing market, which has provided the state with a new opportunity to experiment with an affordable housing solution that aligns with the state’s cultural values. The island state of Hawaii provides a unique opportunity to dissect the importance of sustainable communities and aging in place. Native Hawaiians place tremendous cultural emphasis on the family unit, which makes the state an excellent place to encourage sustainable design in communities to facilitate aging in place. Hawaii has struggled to develop sustainable communities historically with a growing tourism industry that provides significant revenue to the state government playing a large role in the state’s housing market. This has contributed to an unsustainable situation in Hawaii where it has become more difficult to age in place over time. Given this situation, this report will address the following research question:
What factors limit the ability of Hawaiians to “age in place” and how might accessory dwelling units help promote an environment of sustainable communities in Hawaii that fosters such aging in place?
To address this question, the existing literature will be utilized to highlight areas that promote housing affordability and aging in place as well as to highlight areas that are detrimental to aging in place across the state and at the county level. This thesis seeks to provide context for the factors that have prevented sustainable community development by conducting a literature review that encompasses the current state of housing development in Hawaii. Data from the University of Hawaii Economic Research Organization will be used to portray the current state of housing development in each Hawaiian county. My methods will examine how the state of Hawaii has previously utilized accessory dwelling units and discuss the potential for these developments given the statewide barriers Hawaiians face and the connection between Hawaiian culture and these units.
