The preservation of historic districts—is it worth it?

I investigate the welfare effect of conservation areas that preserve historic districts by regulating development. Such regulation may improve the quality of life but does so by reducing housing productivity—that is, the efficiency with which inputs (land and non-land) are converted into housing services. Using a unique panel dataset for English cities and an instrumental variable approach, I find that conservation areas lead to higher house prices for given land values and building costs (lower housing productivity) and higher house prices for given wages (higher quality of life). The overall welfare impact is found to be negative

Game of zones

Posted by Sevrin Waights, LSE Conservation areas seem like an uncontroversial policy. They protect the visual appearance of historic neighbourhoods – for example, by preventing your neighbours installing modern ‘improvements’ such as PVC windows

Does the law of one price hold for hedonic prices?

Hedonic prices of locational attributes in urban land markets are determined by a process of spatial arbitrage that is similar to that which underpins the law of one price. If hedonic prices deviate from their spatial equilibrium values then individuals can benefit from changing locations. I examine whether the law holds for the hedonic price of rail access using a unique historical dataset for Berlin over the period 1890-1914, characterised by massive investment in the transport infrastructure. I estimate the hedonic price of rail access across multiple urban neighbourhoods and time periods to generate a panel dataset of hedonic price differences that I test for stationarity using a panel unit root test. Across multiple specifications I consistently fail to reject the null hypothesis of no unit root and accept the alternative hypothesis that the law holds. My estimates indicate a half-life for convergence to the law of one price that lies between 0.28 and 1.14 years. This result is consistent with spatial equilibrium

Does gentrification displace poor households? An ‘identification-via-interaction’ approach

My theoretical model motivates an ‘identification-via-interaction’ (IvI) approach that separates the causal impact of gentrification on poor exits from endogenous channels. In the empirical analysis, I create a measure of gentrification as the increase in the share of neighbourhood residents who hold a university degree based on the UK Census for 1991, 2001 and 2011. Applying the IvI approach for a sample of private renters from the British Household Panel Survey, 1991–2008, I find that gentrification results in displacement. The IvI approach has general applications in estimating causal relationships where variables are highly endogenous

Essays on the urban economics of housing and land markets

This thesis is comprised of four main chapters. Although the chapters are distinct works, they are related by their focus on housing and land markets and their reliance on urban economic theory and methods. They aim to contribute to the understanding of how these spatial markets function in order to work towards an improved implementation of urban policy. In particular this thesis tries to understand how house prices are determined by demand- and supply-side factors across different scales. It provides support for the idea that at a local level prices are determined by demand, in that they compensate for differences in locational amenities. It also investigates some of the consequences of price determination such as displacement of original residents from gentrifying neighbourhoods and welfare losses as a result of planning restrictions to development. The overall message that emerges from the body of work is that urban policy should pay close attention to the way that supply and demand interact to determine prices in markets for housing and land

Understanding day care enrolment gaps

We document day care enrolment gaps by family background in a country with a universal day care system (Germany). Research demonstrates that children of less educated or foreign-born parents can benefit the most from day care, making it important to understand why such enrolment gaps exist. Using a unique data set that records both stated demand and actual usage of day care we demonstrate that differences in demand cannot fully explain the enrolment gaps. Investigating supply-side factors using quasi-experimental designs, we find that reducing both parental fees and scarcity of places significantly decreases enrolment gaps by parental education but not by parental country of birth. We discuss implications for policy

Center-based care and parenting activities

We estimate the effects of center-based care on parenting activities with children using data from time diaries and a family survey for Germany. Our estimates imply that usage of center-based care reduces the amount of time that a parent spends with their enrolled child, but only small negative effects on the amount of time spent on parenting activities. Correspondingly, center-based care increases parenting activities as a share of time spent with the child. Our estimates of direct (center hours) and indirect effects (evening and weekend) are more pronounced for parents in households where the mother has lower educational attainment

Game of zones: the economics of conservation areas

Provided there are positive external benefits attached to the historic character of buildings, owners of properties in designated conservation areas benefit from a reduction in uncertainty regarding the future of their area. At the same time, the restrictions put in place to ensure the preservation of the historic character limit the degree to which properties can be altered and thus impose a cost to their owners. We test a simple theory of the designation process in which we postulate that the optimal level of designation is chosen so as to Pareto-maximize the welfare of local owners. The implication of the model is that a) an increase in preferences for historic character should increase the likelihood of a designation, and b) new designations at the margin should not be associated with significant house price capitalization effects. Our empirical results are in line with these expectations

Incubators, accelerators and urban economic development

We combine theory and evidence on incubator and accelerator programmes, and their effects on urban economic development. These structured co-working programmes have grown rapidly. However, a rich descriptive literature reveals little about their impact on participants or surrounding urban areas. We situate programmes in a conceptual framework of co-location tools, theorise objectives and benefits, and report findings from systematic, OECD-wide reviews of the evaluation literature. These evaluations provide evidence that accelerators and incubators raise participant employment, with accelerators also aiding access to finance. Ecosystem features such as university involvement and urban economic conditions also influence programme outcomes. However, evaluation evidence is less clear on detailed intervention design. We consider wider lessons and lay out an agenda for future research

Game of zones: the political economy of conservation areas

We develop and test a simple theory of the conservation area designation process in which we postulate that the level of designation is chosen to comply with interests of local homeowners. Conservation areas provide benefits to local homeowners by reducing uncertainty regarding the future of their area. At the same time, the restrictions impose a cost by limiting the degree to which properties can be altered. In line with our model predictions we find that an increase in preferences for historic character by the local population increases the likelihood of a designation, and that new designations at the margin are not associated with significant house price capitalisation effects
