Heat And Observed Economic Activity In The Rich Urban Tropics, Eric Fesselmeyer, Haoming. Liu, Alberto. Salvo, Rhita P B. Simorangkir

Research Collection College of Integrative Studies

We use space-and-time resolved mobility data to assess how heat impacts Singapore, a rich city-state and arguably a harbinger of what is to come in the urbanizing tropics. Singapore’s offices, factories, malls, buses, and trains are widely air conditioned, its public schools less so. We document increased attendance and commuting to workplaces, malls, and the more air-conditioned schools on hotter relative to cooler days, particularly by low-income residents with limited use of adaptive technologies at home. Investment by rich cities may attenuate heat’s pervasive negative consequences on productive outcomes, yet this may worsen the climate emergency in the long run.

Cities In A Pandemic: Evidence From China, Badi H. Baltagi, Ying Deng, Li Jing, Zhenlin Yang

Research Collection School Of Economics

This paper studies the impact of urban density, city government efficiency, and medical resources on COVID-19 infection and death outcomes in China. We adopt a simultaneous spatial dynamic panel data model to account for (i) the simultaneity of infection and death outcomes, (ii) the spatial pattern of the transmission, (iii) the intertemporal dynamics of the disease, and (iv) the unobserved city-specific and time-specific effects. We find that, while population density increases the level of infections, government efficiency significantly mitigates the negative impact of urban density. We also find that the availability of medical resources improves public health outcomes conditional on …

Urbanization Policy And Economic Development: A Quantitative Analysis Of China's Differential Hukou Reforms, Wen-Tai Hsu, Lin Ma

Research Collection School Of Economics

The household registration system (hukou system) in China has hampered rural-urban migration by posing large migration friction. The system has been gradually relaxed in the past few decades, but the reforms have been differential in city size. We find a striking contrast in migration patterns between years 2005 and 2015; rural people tended to move more to large cities in 2005, but more to small- and medium-sized cities in 2015. We calibrate a spatial quantitative model to the world economy in both years with China divided into rural, mega-city, and other-city regions. We find that alternative urbanization policies that are …

Urbanization Policy And Economic Development: A Quantitative Analysis Of China's Differential Hukou Reforms, Wen-Tai Hsu, Lin Ma

Research Collection School Of Economics

The household registration system (hukou system) in China has hampered rural-urban migration by posing large migration friction. The system has been gradually relaxed in the past few decades, but the reforms have been differential in city size and by the coastal-inland divide. We find a striking contrast in the migration patterns between years 2005 and 2015; rural people tended to move more to the coastal urban region in 2005, but more to the inland urban region in 2015. We calibrate a spatial quantitative model to the world economy in both years with China being divided into the rural, coastal urban, …

Building An Equitable And Inclusive City Through Housing Policies: Singapore’S Experience, Sock Yong Phang

Research Collection School Of Economics

Inequality is an age-old concern. In recent years, the rise of income inequality has received worldwide media and policy attention, beginning with the Occupy movement of 2011-2012 and a wave of notable scholastic books such as Stiglitz (2012), Piketty (2014), and Atkinson (2015). Piketty’s Capital in the 21st Century, an unlikely bestseller, contained a vast amount of data showing that the rich are taking rising shares of income and wealth in the advanced economies. Piketty’s approach towards capital and wealth is an aggregative one, and he does not treat real estate or land as a different or distinct form of …

Central Place Theory And The Power Law For Cities, Wen-Tai Hsu, Zou Xin

Research Collection School Of Economics

This chapter provides a review of the link between central place theory and the power laws for cities. A theory of city size distribution is proposed via a central place hierarchy a la Christaller (1933) either as an equilibrium results or an optimal allocation. Under a central place hierarchy, it is shown that a power law for cities emerges if the underlying heterogeneity in economies of scale across good is regularly varying. Furthermore, we show that an optimal allocation of cities conforms with a central place hierarchy if the underlying heterogeneity in economies of scale across good is a power …

Potential Crime Risk And Housing Market Responses, Seonghoon Kim, Kwan Ok Lee

Research Collection School Of Economics

We study how information on local (dis)amenities is transmitted and manifested in housing markets. Using nationwide data on multifamily homes in South Korea, we analyze heterogeneity in the effect of a sex offender's presence on sale prices and rents of nearby homes. Our results demonstrate that the price effect of the offender's move-in varies significantly by spatial context. People react more strongly and persistently to the move-in of the offender in places wherein indicators of social connectedness are stronger, such as places with relatively low population density. We also find that, unlike housing prices, rents do not change in response …

Policy Innovations For Affordable Housing In Singapore: From Colony To Global City, Sock Yong Phang

Research Collection School Of Economics

Global cities today are facing fundamental challenges in relation to unaffordable housing and growing economic inequality. Singapore’s success in making home ownership possible for 90% of its population has attracted much attention internationally. This book represents a culmination of research by the author on key housing policy innovations for affordable housing. Housing policy changes were effected in the 1960s through reforms of colonial legislation and institutions dealing with state land acquisition, public housing, and provident fund savings. The comprehensive housing framework that was established enabled the massive resettlement of households from shophouses, slums and villages to high-rise government-built flats. In …

Singapore: Real State Control, Sock Yong Phang

Research Collection School Of Economics

The author explains how the government of Singapore has taken on the role of land use planner and housing developer to ensure affordable housing. Numerous instruments have been devised by governments to provide affordable housing. These can be classified into four broad categories: taxes and subsidies, land use and market regulations, public-private partnerships, and institutions that supply housing or provide financing.

Housing Policies In Singapore, Sock Yong Phang, Matthias Helble

Research Collection School Of Economics

Singapore has developed a unique housing system, with three-quarters of its housing stock built by the Housing & Development Board (HDB) and homeownership financed through Central Provident Fund (CPF) savings. As a result, the country’s homeownership rate of 90% is one of the highest among market economies. At different stages of its economic development, the Government of Singapore was faced with a different set of housing problems. An integrated land–housing supply and financing framework was established in the 1960s to solve the severe housing shortage. By the 1990s, the challenge was that of renewing aging estates and creating a market …

Cointegration Of Matched Home Purchases And Rental Price Indexes: Evidence From Singapore, Badi H. Baltagi, Jing Li

Research Collection School Of Economics

This paper exploits the homogeneity feature of the Singapore private residential condominium market and constructs matched home purchase price and rental price series using the repeated sales method. These matched series allow us to conduct time series analysis to examine the long-term present value relationship in the housing market. Three key findings are obtained. First, we fail to establish a cointegrating relationship between the home purchase price and rental price based on nationally estimated indexes. Second, area-specific indexes demonstrate strong cross-correlations, invalidating the use of first generation panel unit root tests that ignore these cross-correlations. Third, Pesaran's CIPS test indicates …

Home Prices And Inequality: Singapore Versus Other Global Superstar Cities, Sock Yong Phang

Research Collection School Of Economics

The Global City concept originates from the work of sociologist Saskia Sassen, which dates back to the 1980s. In an age of globalisation, division of labour is international in scope and production activities are distributed across the world. A global city is a significant point where the internationally oriented financial and producer services that make the global economy run choose to agglomerate.

Optimal City Hierarchy: A Dynamic Programming Approach To Central Place Theory, Wen-Tai Hsu, Thomas J. Holmes, Frank Morgan

Research Collection School Of Economics

Central place theory is a key building block of economic geography and an empirically plausible description of city systems. This paper provides a rationale for central place theory via a dynamic programming formulation of the social planner's problem of city hierarchy. We show that there must be one and only one immediate smaller city between two neighboring larger-sized cities in any optimal solution. If the fixed cost of setting up a city is a power function, then the immediate smaller city will be located in the middle, confirming the locational pattern suggested by Christaller. We also show that the solution …

The Fundamental Law Of Highway Congestion Revisited: Evidence From National Expressways In Japan, Wen-Tai Hsu, Hongliang Zhang

Research Collection School Of Economics

The fundamental law of highway congestion states that when congested, the travel speed on an expanded expressway reverts to its previous level before the capacity expansion. In this paper, we propose a theory that generalizes this statement and finds that if there exists a coverage effect, that is, the effect of longer road length on traffic conditional on capacity, then the new equilibrium travel speed could be lower than its previous level. Given the fundamental law, the theory predicts that the elasticity of traffic to road capacity is at least 1. We estimate this elasticity for national expressways in Japan …

Singapore's Housing Policies: 1960-2013, Sock Yong Phang, Kyunghwan Kim

Research Collection School Of Economics

The focus of this case study is on the important role of real estate and housing policies in Singapore’s economic development. In the sphere of housing policy, Singapore is known for its high homeownership rates, the very significant role played by the government in housing supply and housing finance, and the wealth that has been created and distributed in the process.

Central Place Theory And City Size Distribution, Wen-Tai Hsu

Research Collection School Of Economics

This paper proposes a theory of city size distribution via a hierarchy approach rather than the popular random growth process. It does so by formalizing central place theory using an equilibrium entry model and specifying the conditions under which city size distribution follows a power law. Central place theory describes the way in which a hierarchical city system with different layers of cities serving differently sized market areas is formed from a uniformly populated space. The force driving the city size differences in this model is the heterogeneity in economies of scale across goods. The city size distribution under a …

Public Housing: Appreciating Assets?, Sock Yong Phang

Research Collection School Of Economics

The topic of HDB housing is one that is close to the hearts and minds of the majority of Singaporeans. The first part of the presentation will provide a brief overview of price trends in Singapore’s housing sector. The second part delves into the market and policy factors behind the rapid increase in HDB housing prices since 2006. The monograph “Reflections on Housing a Nation” published by the Ministry of National Development in February 2011, contains numerous statements on the goals of housing policy. Briefly, the government is committed to affordable home ownership as a major pillar of Singapore’s public …

Macroeconomic Effects Of Over-Investment In Housing In An Aggregative Model Of Economic Activity, Hian Teck Hoon

Research Collection School Of Economics

Is there a theoretical basis for the view that the end of a period of over-investment necessarily leads to a period of below-normal employment as the excess capital stock is run down? We study the repercussions of a false boom in housing driven by prior expectations of future housing prices not justified by fundamentals. When these expectations are corrected, the result is a precipitous drop in housing prices and, on that account alone, some drop in employment. There is also a bulge in the housing stock. In the case of a closed economy, the downward shift of the term structure …

Collaboration Between The Public And Private Sectors For Urban Development, Sock-Yong Phang

Research Collection School Of Economics

In market economies, the government acts in many ways. In traditional public finance literature, the government taxes and provides public and merit goods. In addition, it regulates the behaviour of firms and individuals. In the context of market failures such as natural monopoly, high risk situations or long life projects, the government may choose to act as producer. In the past two decades, however, public sector collaboration with the private sector to achieve socio-economic objectives has become widely utilised as a method for the provision of the myriad of services that has come to be expected of governments.

Affordable Homeownership Policy: Implications For Housing Markets, Sock Yong Phang

Research Collection School Of Economics

Affordable homeownership is a policy that is often accorded a great deal of policy attention by governments of many countries. This paper aims to examine the market implications of setting a housing price to income ratio target for a market segment by the government. The policy requires active intervention by the government with regard to the targeted sector. The paper uses a simple model of the housing market with a homeownership affordability target to derive the market implications of such targets. In the presence of uncertainty and resource constraints, the objective of homeownership affordability is achieved for the targeted group …
