The Impact of In-house Unnatural Death on Property Values - Evidence from Hong Kong

Zheng CHANG and Jing LI

The occurrence of in-house unnatural death could negatively affect the value of housing property. This study evaluates the geographic and temporal scope of the impact of unnatural death on property values in Hong Kong. By exploiting the spatial and intertemporal variation of the shock in a difference-in-differences approach, we find significant negative externalities of unnatural death incidence on neighborhood housing values. On average, units in which an unnatural death occurred experience a 25% drop in value following the death. Nearby units on the same floor also show a significant price drop of 4.5%. Prices of units on other floors of the same building decline about 2.6%. Units in other buildings of the same estate observe a price decline of about 1% on average. However, the price for nearby estates within 300 meters shows a positive impact of 0.5%, suggesting a very localized sorting mechanism. Temporally, price evolution after death incidence follows a U shape. Housing prices continue to decline up to 4–5 years after deaths and recover gradually afterwards. We also document the heterogeneity of the impact by the type of death incidence (murder, suicide, or accident) and the type of homebuyers (local buyer, investment firm, and other buyers). We find that the negative externalities of death incidence are largely due to a severe stigma effect, rather than channels through the revealed crime risk or the price contagion effect.

Strategic Sequential Bidding for Government Land Auction Sales - Evidence from Singapore

Sumit AGARWAL, Jing LI, Ernie TEO, and Alan CHEONG

This paper studies the extent to which equilibrium auction prices are pushed up sequentially due to strategic bidding behaviors in government land auction sales. Using a unique dataset that covers the universe of tendering prices submitted by all developers for all residential land auction sales in Singapore, we find that a tenderer’s bids are significantly higher where there was a previous land parcel sold within two years and located within four kilometers. The elevated price margin decreases with time and geographic distance. Tracking sequential bids submitted by same developers over time, we find that the incumbent winner of a previous auction often participates in subsequent nearby land sales but does not necessarily win the sites. We argue that the incumbent deliberately bids up the subsequent land prices to gain pricing advantages to their own parcels.

Smart eldercare in Singapore: Negotiating agency and apathy at the margins

Lily KONG and Orlando WOODS

Around the world, smart technologies are being embraced as a cost-efficient means of enabling the elderly to be cared for in new, more non-proximate ways. They can facilitate ageing-in-place, and have the potential to relieve pressure on the providers of care. Yet, the fact is that the interface of technology and society is a negotiated one. These negotiations are most acutely felt when technology is used to supplement the hitherto human-centred process of caregiving, especially amongst “marginalised” societal cohorts, like the elderly. With this, there is a need to better understand the ways in which smart eldercare technologies are used, misused, or not used by those that they are designed to benefit. Drawing on qualitative data derived from triallists of three smart eldercare technologies in Singapore, this paper explores how the lived experience of smart eldercare can cause agentic and apathetic behaviours towards technology to manifest. Specifically, we identify four expectations – of understanding, response, compliance and appreciation – that undermine the potential beneficence of smart eldercare. To conclude, we emphasise the need for more collaborative, and more contextually-sensitive, approaches to the design, development and implementation of smart eldercare solutions.

The digital subversion of urban space: Power, performance and grime

Orlando WOODS

In this article, we survey a growing body of literature within geography and other intersecting fields that trains attention on what inclusive smart cities are, or what they could be. In doing so, we build on debates around smart citizens, smart public participation, and grassroots and bottom-up smart cities that are concerned with making smart cities more inclusive. The growing critical scholarship on such dis- courses, however, alerts us to the knowledge politics that are involved in, and the urban inequalities that are deeply rooted within, the urban. Technological interventions con- tribute to these politics and inequalities in various ways. Accordingly, we discuss limitations of the current discourses around inclusive smart cities and suggest a need for a nuanced definition of ‘inclusiveness’. We also discuss the necessity to further engage with critical data studies in order to ‘know’ what we are critiquing.

The ideological alignment of smart urbanism in Singapore: Critical reflections on a political paradox

Lily KONG and Orlando WOODS

Over the past decade, much has been written about the potential of smart urbanism to bring about various and lasting forms of betterment. The embedding of digital technologies within urban infrastructures has been well documented, and the efficiencies of smart models of urban governance and management have been lauded. More recently, however, the discourse has been labelled ‘hegemonic’, and accused of developing a view of smart technology that is blinkered by its failure to critique its socio-political effects. By focusing on the case of Singapore’s ‘Smart Nation’ initiative, this paper embraces the paradoxes at the heart of smart urbanism and, in doing so, interrogates the tension between ideology and praxis, efficiency and control, access and choice, and smart governance and smart citizenship. It also demonstrates how such tensions are (re)produced through ‘fourthspace’ – the digitally enabled spaces of urbanism that are co-created, and that contribute to an expansion and diffusion of social and political responsibility. It ends by suggesting how such spaces have the potential to radically transform not just the urban environment, but also the role of government and citizens in designing urban futures.

The Impact of the Cost of Car Ownership on House Price Gradient in Singapore

Naqun HUANG, Li JING, and Amanda ROSS

This paper examines the extent to which a change in the cost of car ownership affects the house price gradient with respect to distance from the central business district (CBD). Theory suggests that if the cost of car ownership increases, then people will shift towards other modes of transportation, thus reducing house prices farther away from the CBD. However, the cost of car ownership is likely to be endogenous and correlated with various unobserved factors that also contribute to a change in the house price gradient. To obtain causal effects, we exploit a unique feature of Singapore’s car registration process. All cars in Singapore must have a Certificate of Entitlement (COE), but the number available is restricted based on the traffic concerns of the government and are allocated through a competitive bidding process. We use the number of COEs available each quarter as an instrument for the price of a COE, as the quota is likely to be correlated with the price of the COE but not the price of housing at various distances from the city center. We find that when the price of a COE increases, the price of housing closer to the city center increases, suggesting that increases in the price of a car cause individuals to increase their willingness to pay to locate closer to the CBD.

The impact of weather extremes on urban resilience to hydro-climate hazards: A Singapore case study

Winston T. L. CHOW

Changing frequencies and intensities of extreme weather events directly affect settlement vulnerability; when combined with rapid urbanization, these factors also influence urban resilience to climate-related hazards. This article documents how urban resilience can generally be maximized, before examining how it is impacted by extreme hydro-climatic events (i.e. droughts and floods), with a specific case examination for Singapore. In particular, analysis of Singapore’s climate from 1950 to 2015 indicates (1) a warmer environment, and (2) recent periods of more intense surface dryness. Lastly, this article suggests how specific climate information regarding extreme event attribution can aid municipal stakeholders involved in urban resilience policy.

A multimethod approach towards assessing urban flood patterns and its associated vulnerabilities in Singapore

Winston T. L. CHOW, Brendan D. CHEONG, and Beatrice H. HO

We investigated flooding patterns in the urbanised city-state of Singapore through a multimethod approach combining station precipitation data with archival newspaper and governmental records; changes in flash floods frequencies or reported impacts of floods towards Singapore society were documented. We subsequently discussed potential flooding impacts in the context of urban vulnerability, based on future urbanisation and forecasted precipitation projections for Singapore. We find that, despite effective flood management, (i) significant increases in reported flash flood frequency occurred in contemporary (post-2000) relative to preceding (1984–1999) periods, (ii) these flash floods coincide with more localised, “patchy” storm events, (iii) storms in recent years are also more intense and frequent, and (iv) floods result in low human casualties but have high economic costs via insurance damage claims. We assess that Singapore presently has low vulnerability to floods vis-a-vis other regional cities largely due to ` holistic flood management via consistent and successful infrastructural development, widespread flood monitoring, and effective advisory platforms. We conclude, however, that future vulnerabilities may increase from stresses arising from physical exposure to climate change and from demographic sensitivity via rapid population growth. Anticipating these changes is potentially useful in maintaining the high resilience of Singapore towards this hydrometeorological hazard.

Assessment of measured and perceived microclimates within a tropical urban forest

Winston T. L. CHOW, Siti Nur ‘Assyakirin Binte Ali AKBAR, Su Li HENG, and Matthias ROTH

Urban greenery is a favoured approach applied towards reducing urban warmth and climate discomfort, but ascertaining its measured and perceived effectiveness in tropical climates is relatively understudied. To this end, we investigated microclimate differences within an urban park (the Singapore Botanic Gardens) to assess if variations in plot-scale land cover affect both objective (measured) and subjective (surveyed) microclimate data. Over two monsoonal seasons, we obtained data from four distinct sites—a tropical rainforest stand, a palm tree valley, a water-body feature, and the park visitors’ centre. Measured climate data (e.g. air temperature, vapour pressure, wind velocity and globe temperatures) were used to derive mean radiant temperature Tmrt and three thermal comfort indices (e.g. temperaturehumidity index THI, physiological equivalent temperature PET, and wet-bulb globe temperature WBGT). Concurrent to these measurements, we also surveyed park users (n = 1573) for perceived microclimate sensations and preferences in thermal, humidity, wind and sun exposure, as well as their overall assessment of climate comfort/discomfort. The results indicate significant differences in both measured and perceived microclimates over different sites and seasons, with (i) selected heat stress thresholds based on thermal comfort indices exceeded at several sites, and (ii) visitors perceived generally hot, humid and low-wind conditions throughout. Variations in respondent acclimatisation to tropical climates are observed between correlations of WBGT and some sensation votes, with apparently stronger correlations with more acclimated respondents. While humidity was voted as the most uncomfortable climate variable across all sites, a large majority of respondents felt comfortable climate conditions throughout. Present results confirm that vegetation canopy characteristics affecting wind and sun exposure appear to be important factors in outdoor thermal comfort. Lastly, we suggest that future tropical outdoor thermal comfort studies consider the critical aspects of site humidity and wind to discern comfort/discomfort levels.

The Impact of Agglomeration Economies on Hospital Input Prices

Andrew FRIEDSON and Jing LI

This paper examines the extent to which agglomeration of the hospital service industry enhances the productivity of producing health care. Specifically, we use a large set of private insurance claims from the FAIR Health database to show that an increasing spatial concentration of hospital services results in a decreased cost of obtaining intermediate medical services. We explicitly test whether the reduced cost at concentrated locations arises from the ability to share intermediate service providers. The identification relies on state variation in medical lab technician licensure requirements, which influence the cost of intermediate services only through the cost of running a lab. Our findings suggest that agglomeration of the hospital service industry attracts specialized medical labs, which in turn help to reduce the cost of producing laboratory tests.
