Over the last several years, new transportation service business platforms like Uber and Lyft have appeared in cities across the U.S. Since these new business models do not fit into existing regulatory and policy frameworks, and their entrance into markets is typically abrupt and sometimes illegal, these companies, which have come to be known as transportation network companies (TNCs), provoke city governance actors and the public to react in many different ways. Some cities take a free market approach, while others opt toward heavy handed regulation. In addition to policy action, there is a great deal of policy narrative swirling around these services and their place in existing mobility systems. There is wide variation in the dominant stories or narratives that emerge about TNCs when they suddenly enter a metropolitan market. Said narratives about these mobility providers also evolve as the companies continually operate in different cities. Some stories are thematically tied to specific interest groups and others seem to originate as a result of specific contextual nuances or incidents that occur. Sometimes stories originate in the context of local, state or national political backdrops and discourse. This dissertation argues that stories emerge in the context of urban regime characteristics. Using urban regime theory along with Mark Bevir and R.A.W. Rhodes decentered theory of governance, I will look at TNC operation in four U.S. cities: Indianapolis, IN, Austin, TX, Portland, OR, and Washington, DC. This dissertation explores the ways in which narratives emerge and change around TNCs, how those narratives are influenced by existing urban regime dynamics, and how they influence policy making. / PHD / Over the last several years, private sector mobility companies like Uber and Lyft have started operating in cities across the U.S. Despite the fact that these companies provide services that already exist with more traditional transportation providers (such as taxi cabs) and their business models are very rote and consistent across locations, city policy actors respond to them in many different ways. There is also wide variation in the sorts of stories or narratives that develop when these companies deploy and operate in different cities. Those stories sometimes reflect local political nuances and characteristics. Using urban regime theory along with Mark Bevir and R.A.W. Rhodes decentered theory of governance, I will use this research to explore the ways in which narratives emerge and change around TNCs in four cities: Indianapolis, IN, Austin, TX, Portland, OR, and Washington, DC. I will look at how those narratives are influenced by existing local nuances, coalitions and characteristics, and how they might influence policy making and responses in those places.
