Allocating Vehicle Registration Permits, Massimiliano Landi, Domenico Menicucci

Research Collection School Of Economics

We compare social welfare, consumer surplus and profits in two different institutional settings in which an item whose quantity is fixed and controlled (vehicle registration permit) is allocated to the buyers of a complementary good (car). In the first setting, which resembles the way in which vehicle registration permits are allocated in Singapore, the central planner runs a uniform price auction for permits in which the consumers who bid the highest receive the permits and pay the highest losing bid. Then each winning consumer purchases a car from a seller. In the alternative setting, the central planner first allocates the …

Housing Markets Since Shapley And Scarf, Mustafa Oguz Afacan, Gaoji Hu, Jiangtao Li

Research Collection School Of Economics

Shapley and Scarf (1974) appeared in the first issue of the Journal of Mathematical Economics, and is one of the journal’s most impactful publications. As we approach the remarkable milestone of the journal’s 50th anniversary (1974–2024), this article serves as a commemorative exploration of Shapley and Scarf (1974) and the extensive body of literature that follows it.

Tackling Misperceptions About Immigrants With Fact-Checking Interventions: A Randomized Survey Experiment, Syngjoo Choi, Chung-Yoon Choi, Kim

Research Collection School Of Economics

We conduct a randomized online survey experiment to study the impact of fact-checking offers and financial incentives on misperceptions about immigrants. We find that natives overestimate the number of immigrants and the social and economic costs of immigration. Offering a free check of the factual information about immigrants reduces these misperceptions; it becomes more effective when combined with financial incentives. However, more than half of the participants never took up offers to check factual information. Using a model of information search with limited attention, we identify the presence of non-negligible costs of information search and processing, which limits the effectiveness …

Does Fertility Matter For Middle Aged And Older Adults’ Risk Attitudes?, Christine Ho, Bussarawan Teerawichitchainan, Joanne Tan, Eugene Rui Le Tan

Research Collection School Of Economics

Given that risk attitudes influence many decisions, it is important to understand the factors that shape such attitudes in late adulthood, when individuals face important risky decisions. While research finds that parenthood tends to correlate with lower risk tolerance in western countries, there is a lacuna on whether such associations persist in late adulthood, and are applicable to the Asian context, where children are conventionally considered a linchpin of old age support. Data for middle aged and older individuals come from the nationwide Singapore Life Panel (N = 6,740). Multivariate statistical analyses are employed to estimate the associations between willingness …

The Importance Of The First Generic Substitution: Evidence From Sweden, Aljoscha Janssen, David Granlund

Research Collection School Of Economics

We analyze changes in the willingness to substitute from prescribed pharmaceuticals to more affordable generic equivalents in response to the first experience with a substitution. Using Swedish individual-level data of prescribed and dispensed pharmaceuticals, we em-ploy a dynamic event study and an instrumental variable approach to show that an initial substitution reduces the probability of opposing subsequent substitutions by 39 percent-age points. We recommend that policy-makers target patients with a history of opposed substitution and offer additional discounts to promote substitution as long-term savings outweigh one-time costs.

The Impact Of Upzoning On Housing Construction In Auckland*, Ryan Greenaway-Mcgrevy, Peter C. B. Phillips

Research Collection School Of Economics

There is a growing debate about whether upzoning is an effective policy response to housing shortages and unaffordable housing. This paper provides empirical evidence to further inform debate by examining the various impacts of recently implemented zoning reforms on housing construction in Auckland, the largest metropolitan area in New Zealand. In 2016, the city upzoned approximately three quarters of its residential land to facilitate construction of more intensive housing. We use a quasi-experimental approach to analyze the short-run impacts of the reform on construction, allowing for potential shifts in construction from non-upzoned to upzoned areas (displacement effects) that would, if …

Search Models Of Money: Alternative Means-Of Payment And Consumer Behaviour With Credit, Kheng Tat Marcus Tan

Dissertations and Theses Collection (Open Access)

This dissertation consists of three chapters on Search Models of Money.

The first chapter is a review of recent advances in Search Models of Money. It reviews the Lagos and Wright (2005) framework which is the workhorse of many modern search models with applications to models with Competing Media of Exchange to Fiat Currency, and models with Money and Credit. We trace the history of the development of search models of money from the first generation to present day. We highlight recent developments that address puzzles such as the coexistence of money in an environment where an asset serves as …

Teaching In The Right Context: Textbook Supply Program, Language, And Vocabulary Ability In Vietnam, Tomoki Fujii, Maki Nakajima, Sijia Xu

Research Collection School Of Economics

An ethnic gap in education is prevalent around the world. This remains the case in Vietnam, a country that has achieved phenomenal economic growth and raised the educational attainment of the public. This paper examines the impact of language policy reorientation represented by the textbook supply program in Vietnam on the ethnic gap in children's learning measured by a vocabulary test. Applying difference-in-differences estimation to the Young Lives data between 2006 and 2015, we show that the program became more effective in narrowing the ethnic gap as the education policy became reoriented toward ethnic minority children. A causal mediation analysis …

Concerns Over The Cost Of Living Among Older Adults In Singapore, Rachel Ngu, Micah Tan, Paulin T. Straughan, Seonghoon Kim, William Tov, Grace Cheong, Xiaoyan Zhang

ROSA Research Briefs

A post-National Day Rally survey conducted in August 2022 found that the rising cost of living and health-related issues were ranked among the top concerns of Singaporeans (Baharudin, 2022). This comes as no surprise as global crises such as the ongoing COVID-19 pandemic and the Russo-Ukrainian conflict, has resulted in global and domestic inflation (Gov.sg, 2022). In May 2022, Singapore reported a 13-year high core inflation of 3.6% (Channel News Asia, 2022), while in September 2022, Singapore’s core inflation had risen to 5.3% (Ang, 2022). Additionally, the government announced that Singapore residents will see a goods and services tax (GST) …

Life Satisfaction Changes And Adaptation In The Covid-19 Pandemic: Evidence From Singapore, Terence C. Cheng, Kim, Kanghyock Koh

Research Collection School Of Economics

We provide novel evidence on how COVID-19 affected overall life satisfaction using a monthly longitudinal survey of middle-aged and older Singaporeans. We study how the subjective well-being of individuals evolves over the course of 18 months including the outbreak of the pandemic, the implementation of the lockdown and the spike of cases due to the delta variant in a country where COVID-19 is controlled in a sustained manner. Using an event-study design framework, we find large declines in overall life satisfaction in the lead-up to and following the lockdown. Fifteen months after the outbreak of the pandemic, and 13 months …

Is Fed Policy In The Eye Of The Beholder?, Leo Krippner, Thomas Lam

Sim Kee Boon Institute for Financial Economics

While the US Federal Reserve remains vigilant on inflation, it will likely continue its tightening cycle with caution, with an eye on market expectations about future policy actions and financial conditions.

Intra-Firm Hierarchies And Gender Gaps, Nicolo Dalvit, Aseem Patel, Joanne Tan

Research Collection School Of Economics

We study how changes in female representation at the top of a firm’s organisation affect gender-specific outcomes across hierarchies within firms. We start by developing a theoretical model of a hierarchical firm, where gender representation in top organisational layers can affect gender-specific hiring and promotion probabilities at lower layers. We then exploit a recent French reform that imposed gender representation quotas in the boards of directors and test the model’s predictions in the data. Our empirical results show that the reform was successful in reducing gender wage and representation gaps at the upper layers of the firm, but not at …

Strategic Parent Meets Detached Child? Parental Intended Bequest Division And Support From Children, Christine Ho

Research Collection School Of Economics

Whereas the literature has found that elderly parents may use bequests to reward children who provide them with time support, there is limited evidence on whether younger less needy parents may base their intended bequest division on alternative forms of support from children. Using a large-scale dataset of middle-aged and older Singaporeans, I find that parents intend to leave larger bequest shares to coresident children and to children who provide greater material support. Parents also intend to bequeath more to children in whom they confide frequently while they bequeath more to children in whom they rarely confide when the latter …

Weight Perceptions And Health Education On Obesity Among Older Adults, Seonghoon Kim, Vicky Mengqi Qin, Xuan Zhang, Kanghyock Koh, Mindy Eiko Tadai, Micah Tan

ROSA Research Briefs

The current brief presents preliminary findings from a special module that measures perceptions of weight and receptivity to health education among older adults. Singapore Life Panel® (SLP) data collected in January 2022 (n=2814) were utilized. Two policy recommendations were made: The main findings highlight that weight misperception is prevalent among older adults. More than a third of respondents (39%) incorrectly perceive their weight status, particularly among overweight and obese older adults, as well as Malay and lower educated respondents. This suggests the importance of public health education for older adults to reduce misperceptions about their own over- and under-weight status, …

Life In An Endemic Covid-19: Older Adults' Well-Being, Activity, And Perceptions, Rachel Ngu, Micah Tan, Jia Ying Low

ROSA Research Briefs

The current research brief provides a preliminary examination of whether older adults have been able to ‘return’ to the pre-pandemic way of life in an endemic COVID-19. To do this, we look at several key indicators, including (1) tracking older adults’ overall life satisfaction, activity levels, and trust in government over the past 3 years, (2) older adults’ confidence to resume activities, as well as subjective perceptions about their safety when leaving the home in an endemic COVID-19, and (3) older adults’ ability to adhere to the Home Recovery Program (HRP), where individuals with COVID-19 are able to recover from …

Three Essays On Development Economics And Human Capital, Arpita Khanna

Dissertations and Theses Collection (Open Access)

In the first chapter, we estimate the impact of exposure to the 2015 Nepal Earthquake on intimate partner violence with two rounds of Demographic and Health Surveys data. Using differences-in-differences estimation, we find that exposure to the earthquake lead to a statistically and economically significant increase in intimate partner violence in the urban areas but not in the rural areas. This is possibly due to an increase in the stress felt by the victims. We also offer some evidence that the impact heterogeneity between the urban and rural areas is attributable to the differences in the reconstruction processes and assistance …

Start-Up Firms And Corporate Culture: Evidence From Advertised Corporate Culture, Jungho Lee

Research Collection School Of Economics

I document advertised corporate culture among start-up firms from an online job board. Two corporate-culture types emerge, one that concerns the well-being of em- ployees (worker-centered culture) and another that emphasizes other values, such as cus- tomers, firms, and markets (firm-centered culture). The worker-centered culture attracts 20% more applications than the other culture type. Firms advertising the worker-centered culture exploit worker preference by paying 5% lower salaries than measurably similar jobs. Using a standard model of business creation, I show financially constrained start- ups are incentivized to advocate popular culture, even though doing so is not optimal without financial constraints.

Forced Moves And Home Maintenance: The Amplifying Effects Of Mortgage Payment Burden On Underwater Homeowners, John Harding, Li Jing, Stuart Rosenthal, Xirui Zhang

Research Collection School Of Economics

Although the adverse effect of high loan to value ratios (LTV) on mortgage default is known, the potential amplifying effect of high payment-to-income (PTI) ratios that can force families out of their homes has received limited attention. High PTI and LTV can also add to default costs by discouraging home maintenance. Using the 1985-2013 AHS panel, we show that high PTI prompts families to move and especially so for households with LTV above 120%. This lends support for policies like HAMP and HARP that seek to reduce forced moves and mortgage default by lowering mortgage payment burden for financially stressed …

Geopolitics And Ballpark Estimates, Thomas Lam, David Fernandez

Sim Kee Boon Institute for Financial Economics

Most economist commenced 2022 with 3 key assumptions on the global economy:

1) Some policy normalisation and reversal, though cautious and uneven, are likely to occur in economies with above-average growth and inflation;

2) The Covid-19 infection wave, while presumably asymmetric and recurrent across countries, appears to have less of an imprint on cyclical activity on balance;

3) The lingering supply disruptions resulting from the pandemic, albeit still intense and widespread, should be easing gradually.

Assessing Gender Parity In Intrahousehold Allocation Of Educational Resources: Evidence From Bangladesh, Sijia Xu, Abu S. Shonchoy, Tomoki Fujii

Research Collection School Of Economics

Gender parity in education—an important global development goal—has been primarily measured through school enrollment, and the gender parity in education quality has received limited attention until recently. We address this issue by highlighting the intrahousehold allocation of education expenditure. We extend the hurdle model into a three-part model to enable decomposition of households’ education decisions into enrollment, total education expenditure, and share of the total education expenditure on the core component, or items relating to the quality of education such as private tutoring. We apply this model to four rounds of nationally representative household surveys from Bangladesh, a country that …

Short-Term Impact Of Covid-19 On Consumption Spending And Its Underlying Mechanisms: Evidence From Singapore, Seonghoon Kim, Kanghyock Koh, Xuan Zhang

Research Collection School Of Economics

We examine the short-term impact of COVID-19 on consumption spending and labor market outcomes. Using monthly panel data of individuals mainly aged 50–70 in Singapore, we find that COVID-19 reduced consumption spending and labor market outcomes immediately after its outbreak, and its negative impact quickly evolved. At its peak, the pandemic reduced total household consumption spending by 22.8% and labor income by 5.9% in April. Probability of full-time work also went down by 1.2 pp and 6.0 pp in April and May, respectively, but employment and self-employment were only mildly affected. Our heterogeneity analysis indicates that the reduction in consumption …

Domains For Well Behaved Monotonic Social Choice Functions, Salles Paulo Daniel Ramos

Research Collection School Of Economics

We present here a set of necessary and sufficient conditions for an MD-Connected Domain to support a Well Behaved Monotonic Social Choice Function. We require the domain to have a minimal number of preferences in which a pair of alternatives flips their relation, and these reversals must occurr in accordance to a tree graph. While this condition cannot be sum-marized by a set of restrictions on individual preferences, we provide two alternative characterizations that can, one that is necessary and another that is sufficient.

Heterogeneous Health Effects Of Medical Marijuana Legalization: Evidence From Young Adults In The United States, Junxing Chay, Seonghoon Kim

Research Collection School Of Economics

Legalizing marijuana for medical purposes is a longstanding debate. However, evidence of marijuana's health effects is limited, especially for young adults. We estimate the health impacts of medical marijuana laws (MML) in the U.S. among young adults aged 18–29 years using the difference-in-differences method and data from the Behavioral Risk Factors Surveillance System. We find that having MMLs with strict regulations generate health gains, but not in states with lax regulations. Our heterogeneity analysis results indicate that individuals with lower education attainments, with lower household income and without access to health insurance coverage gain more health benefits from MML with …

What Drives Subjective Well-Being In Singapore’S Youth?, Kong Weng Ho, Smu Office Of Research

Research@SMU Infographics

Subjective well-being, which is the scientific term for happiness and life satisfaction, can impact productivity and health. It is driven by three determining factors – the quality of relationships (relationship stocks), life aspirations and perceived opportunities. Research conducted by SMU Associate Professor Ho Kong Weng examined how these factors affect the subjective well-being of Singapore’s youth.

Jue Insight: Migration, Transportation Infrastructure, And The Spatial Transmission Of Covid-19 In China, Bingjing Li, Lin Ma

Research Collection School Of Economics

This paper evaluates the impacts of migration flows and transportation infrastructure on the spatial transmission of COVID-19 in China. Prefectures with larger bilateral migration flows and shorter travel distances with Hubei, the epicenter of the outbreak, experienced a wider spread of COVID-19. In addition, richer prefectures with higher incomes were better able to contain the virus at the early stages of community transmission. Using a spatial general equilibrium model, we show that around 28% of the infections outside Hubei province can be explained by the rapid development in transportation infrastructure and the liberalization of migration restrictions in the recent decade.

Does A District Mandate Matter For The Behavior Of Politicians? An Analysis Of Roll-Call Votes And Parliamentary Speeches, Andreas Born, Aljoscha Janssen

Research Collection School Of Economics

In most democracies, members of parliament (MPs) are elected either through a party list or by a district. We use a discontinuity in the German electoral system to investigate the causal effect of a district election on an MP’s conformity with the party line. A district election does not affect roll-call voting behavior causally, possibly due to overall high adherence to party-line voting. Analyzing the parliamentary speeches of each MP allows us to overcome the high party-line discipline with regard to parliamentary voting. Using textual analysis and machine learning techniques, we create two measures of closeness of an MP’s speeches …

Economic Impact Of Targeted Government Responses To Covid-19: Evidence From The Large-Scale Cluster In Seoul, Kim, Kanghyock Koh, Jinwook Shin

Research Collection School Of Economics

We estimate the economic impact of South Korea's targeted responses to the first large-scale COVID-19 cluster in Seoul. We find that foot traffic and retail sales decreased only within a 300 meter radius of the cluster and recovered to its pre-outbreak level after four weeks. The reductions appear to be driven by temporary business closures rather than the risk avoidance behavior of the citizens. Our results imply that less intense, but more targeted COVID-19 interventions, such as pin-pointed, temporary closures of businesses, can be a low-cost alternative after lifting strict social distancing measures.

Does Precise Case Disclosure Limit Precautionary Behavior? Evidence From Covid-19 In Singapore, Aljoscha Janssen, Matthew H. Shapiro

Research Collection School Of Economics

Limiting the spread of contagious diseases can involve both government-managed and voluntary efforts. Governments have a number of policy options beyond direct intervention that can shape individuals’ responses to a pandemic and its associated costs. During its first wave of COVID-19 cases, Singapore was among a few countries that attempted to adjust behavior through the announcement of detailed case information. Singapore's Ministry of Health maintained and shared precise, daily information detailing local travel behavior and residences of COVID-19 cases. We use this policy along with device-level cellphone data to quantify how local and national COVID-19 case announcements trigger differential behavioral …

The Price Elasticity Of African Elephant Poaching, Quy-Toan Do, Andrei A. Levchenko, Lin Ma, Julian Blanc, Holly Dublin, Tom Milliken

Research Collection School Of Economics

The objective of this paper is to provide an estimate of the elasticity of elephant poaching with respect to prices. Ivory being a storable commodity subjects its price to Hotelling’s no-arbitrage condition, hence allowing identification of the supply curve. The price of gold, one of many commodities used as stores of value, is thus used as an instrument for ivory prices. The supply of illegal ivory is found to be price inelastic with an elasticity of 0.4, with changes in consumer prices passing-through to prices faced by producers at a rate close to unity. Estimations based on a number of …
