Item Planning towards an equitable sharing economy: On housing, on transportation, on policymaking(2021) Zou, Zhenpeng; Knaap, Gerrit; Urban and Regional Planning and Design; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)The sharing economy has experienced phenomenal growth in the past decade. Its two most popular sectors, short-term rental (STR) and shared mobility, have significantly transformed people’s travel behavior and disrupted the urban housing/transportation markets. On the other hand, planning and policy efforts lag behind the growth of the sharing economy due to its novelty and its market-based business model. In this dissertation, I use three empirical studies to demonstrate one of those planning and policymaking challenges from the equity perspective. In the first study, I investigate the impact of STR on single-family housing prices in Washington DC using a data-driven, hedonic analytical framework. Not only do I find a significant price inflation as a result of increasing STR activities, but I also identify the spatially uneven impacts that can adversely affect housing affordability in some minority-populated neighborhoods in the city. In the second study, I focus on the built and social environment factors to explain the spatial distribution of e-scooter sharing trips on Washington DC’s streets. Using real-time, trip trajectory level data, I am able to examine not only the built environment factors for a trip’s origin and destination neighborhoods, but also the street design factors for a trip’s traversing paths. Moreover, I apply a machine-learning based clustering analysis to segment trips by their temporal patterns, built environment, and social environment attributes. With both data-intensive analyses, I identify potential equity issues and opportunities associated with the emerging e-scooter sharing in DC. In the third study, I expand my analysis on STR and shared micromobility in a cross-city, cross-section exploration. I find similar tourist-oriented spatial patterns for three types of activities, including STR, station-based bike-sharing, and dockless bike/e-scooter sharing. Additionally, I find a significant lag in their uses in socially disadvantaged neighborhoods in eight cities, as well as identifying a potential connection between active STR business and gentrification in communities of high social vulnerability. The policy heterogeneities within the eight cities provide different angles to understand the feasible and effective planning practices and policy approaches to address the equity concerns on the rising sharing economy.Item HOUSING DEMAND AND TENURE CHOICE FOR SENIOR CITIZENS: LESSONS FROM THREE ESSAYS(2020) Kim, Jinyhup; Dawkins, Casey J; Urban and Regional Planning and Design; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)The U.S. housing market faces a huge surge brought on by the growth of the older population. Housing researchers and gerontologists are now focusing on potential challenges that older households could face over the coming decades and are attempting to estimate how such challenges will affect the housing market. This marks a critical point for assessing housing affordability, availability of accessible housing, and housing demands based on geographical locations – all of which will be of utmost importance to aging populations in the coming decades. Although the older population is growing rapidly and is receiving considerable attention from both researchers and policymakers, there have been relatively few empirical studies about the housing behaviors of older Americans. This dissertation examines the aforementioned three challenges through empirical essays by employing micro-data (e.g., the 2004–2014 Health and Retirement Study, the 2011 American Housing Survey, and the 2013–2017 Public Use Microdata Sample). Specifically, the first paper will examine the reasons why elderly homeowners make the downward transition from homeownership, with a particular focus on the significance of property taxes on elderly behaviors. The second paper will investigate the living conditions of existing housing for stayers – those who have remained in their place of dwelling since reaching the retirement age of 65 – and estimate how accessible their housing is to meet the daily needs for aging in place. The third paper will seek empirical determinants on residential mobility and housing choices by elderly households in the Baltimore MSA, accessing the net impact of individual and housing attributes on migration behaviors and housing consumption. The results of these analyses show that property tax abatement programs fail to provide tax subsidies targeted to low income seniors in need. Furthermore, policy approaches to grow the accessible housing stock have proven largely unsuccessful. Finally, seniors who migrate throughout the Baltimore MSA show a strong tendency to downsize and become renters – particularly of apartments – regardless of location. This research will provide timely new evidence, which will help decision-makers better understand the burning issues that impact aging adults’ housing-related behaviors in the U.S. housing market.Item A BETTER NEIGHBORHOOD FOR HOUSING VOUCHER HOUSEHOLDS: OBSTACLES AND OPPORTUNITIES(2017) Jeon, Jae Sik; Dawkins, Casey J; Urban and Regional Planning and Design; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Since the 1970s, the emphasis of federal housing policy has shifted from place-based subsidies to tenant-based subsidies that are provided directly to low-income households for the purpose of renting in the private market. Although many hoped that the Housing Choice Voucher, a tenant-based housing assistance program, would be a new tool in the fight against concentrated poverty and its associated problems, housing voucher recipients still face obstacles when trying to secure housing in high-opportunity neighborhoods over the long-term. The growing body of evidence linking neighborhood conditions to household outcomes points to the need for a better understanding of how housing vouchers improve access to opportunities. While previous studies have explored neighborhood outcomes of housing voucher recipients, it still remains unclear what factors play a significant role in their residential location choices. My dissertation examines the constraints that housing voucher households face in neighborhood choices. Drawing upon data from the Moving to Opportunity experiment, it specifically analyzes trends in affordable housing inequality, estimates the effect of vehicle access on locational attainment, and explores social networks as a determinant of mobility behavior. The results of these analyses show that obstacles such as affordable housing inequality across the metropolitan area, strong social networks in the initial, poor neighborhood, and a lack of access to vehicles negatively affect the likelihood of moving to neighborhoods in which opportunities are expanded for low-income households. My findings shed light on the dynamics of residential mobility and neighborhood improvements for low-income households. The expansion of the Housing Choice Voucher program, supported by localized payment standard, connection to automobile subsidies, and extensive housing search services that provide information about the opportunities available in across all geographic units, may have a significant impact on poverty de-concentration and access to opportunity over time. These findings are also expected to bridge the gap between research and policy with regard to how housing voucher program could be improved in the context of the federal government’s charge to Affirmatively Further Fair Housing (AFFH).Item CLIMATE ACTION PLANS - FACT OR FICTION? EVIDENCE FROM MARYLAND(2013) Welch, Timothy F.; Ducca, Fred; Urban and Regional Planning and Design; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)On a sweltering summer day in 1988, NASA scientist James Hansen sounded the alarm, in a congressional hearing, that human activity was changing our climate and without action, the world would face grave danger. Since that time, the United States government has ignored international climate policy efforts and failed multiple times to enact federal guidelines to address this serious problem. In the last decade, state governments have begun to formulate their own climate policy in an effort called Climate Action Planning. Climate action plans seek aggressive reductions and form the backbone of most statewide environmental policies but they often suffer from a lack of scientific analysis, unrealistic expectations, little funding, non-existent implementation strategies, and have no enforcement mechanisms. While plans have proliferated across the nation, little has been done to examine closely the ability of the policies to achieve climate change mitigation goals through enumerated strategies. This thesis fills part of the research void by examining all of the built environment emissions reduction strategies specified in the Maryland CAP. The analysis proceeds by developing multiple models calibrated with local empirical data. The results of this analysis show that Maryland, even with a successful implementation of its CAP will not meet its carbon mitigation targets. Further analysis reveals that a full state, national, and global implementation of similar carbon reduction targets would not alter the trajectory of climate change. To address climate change adequately, Maryland should take a three-prong approach. First, strengthen the mitigation strategies that show the greatest potential to reduce CO2 while abandoning strategies that do not. Second, extend the current set of strategies to include the low hanging and quickly implementable mitigation `fruit'. Third, in the face of serious and inevitable climate change, begin to adapt the built environment for better resiliency to more extreme conditions. The thesis concludes with a call to action for urban planners to address ambiguities that relate to the climate change and the build environment. The timing is "ripe" for planners to take the lead in what will certainly become the next great wave of planning.
