Economic Forecasting In A Pandemic: Some Evidence From Singapore, Hwee Kwan Chow-Tan, Keen Meng Choy May 2023

Economic Forecasting In A Pandemic: Some Evidence From Singapore, Hwee Kwan Chow-Tan, Keen Meng Choy

Research Collection School Of Economics

This paper aims to investigate whether the predictive performance and behaviour of professional forecasters are different during the COVID-19 pandemic as compared with the global financial crisis of 2008 and normal times. To this end, we use a survey of professional forecasters in Singapore collated by the central bank to analyse the forecasting records for GDP growth and CPI inflation for the period 2000Q1–2021Q4. We first examine the point forecasts to document the extent of forecast failure duringthe two crises and explore various explanations for it, such as leader-following and herding behaviour. Then, using percentile-based summary measures of probability distribution …


Cities In A Pandemic: Evidence From China, Badi H. Baltagi, Ying Deng, Li Jing, Zhenlin Yang Mar 2023

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 …


Life Satisfaction Changes And Adaptation In The Covid-19 Pandemic: Evidence From Singapore, Terence C. Cheng, Kim, Kanghyock Koh Dec 2022

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 …


Associations Of The Covid-19 Pandemic With Older Individuals' Healthcare Utilization And Self-Reported Health Status: A Longitudinal Analysis From Singapore, Sangnam Ahn, Seonghoon Kim, Kanghyock Koh Dec 2022

Associations Of The Covid-19 Pandemic With Older Individuals' Healthcare Utilization And Self-Reported Health Status: A Longitudinal Analysis From Singapore, Sangnam Ahn, Seonghoon Kim, Kanghyock Koh

Research Collection School Of Economics

Background: The COVID–19 pandemic has challenged the capacity of healthcare systems around the world and can potentially compromise healthcare utilization and health outcomes among non-COVID–19 patients. Objectives: To examine the associations of the COVID-19 pandemic with healthcare utilization, out-of-pocket medical costs, and perceived health among middle-aged and older individuals in Singapore. Method: Utilizing data collected from a monthly panel survey, a difference-in-differences approach was used to characterize monthly changes of healthcare use and spending and estimate the probability of being diagnosed with a chronic condition and self-reported health status before and during the COVID-19 outbreak in 2020. Subjects: Data were …


The Intergenerational Mortality Tradeoff Of Covid-19 Lockdown Policies, Lin Ma, Gil Shapira, Damien De Walque, Quy-Toan Do, Jed Friedman, Andrei A. Levchenko Aug 2022

The Intergenerational Mortality Tradeoff Of Covid-19 Lockdown Policies, Lin Ma, Gil Shapira, Damien De Walque, Quy-Toan Do, Jed Friedman, Andrei A. Levchenko

Research Collection School Of Economics

In lower-income countries, the economic contractions that accompany lockdowns to contain COVID-19 transmission can increase child mortality, counteracting the mortality reductions achieved by the lockdown. To formalize and quantify this effect, we build a macro-susceptible-infected-recovered model that features heterogeneous agents and a country-group-specific relationship between economic downturns and child mortality and calibrate it to data for 85 countries across all income levels. We find that in some low-income countries, a lockdown can produce net increases in mortality. The optimal lockdown that maximizes the present value of aggregate social welfare is shorter and milder in poorer countries than in rich ones.


Short-Term Impact Of Covid-19 On Consumption Spending And Its Underlying Mechanisms: Evidence From Singapore, Seonghoon Kim, Kanghyock Koh, Xuan Zhang Feb 2022

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 …


Jue Insight: Migration, Transportation Infrastructure, And The Spatial Transmission Of Covid-19 In China, Bingjing Li, Lin Ma Jan 2022

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 Precise Case Disclosure Limit Precautionary Behavior? Evidence From Covid-19 In Singapore, Aljoscha Janssen, Matthew H. Shapiro Dec 2021

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 …


Economic Impact Of Targeted Government Responses To Covid-19: Evidence From The Large-Scale Cluster In Seoul, Kim, Kanghyock Koh, Jinwook Shin Dec 2021

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.


Economic Forecasting In An Epidemic: A Break From The Past?, Hwee Kwan Chow, Keen Meng Choy Dec 2021

Economic Forecasting In An Epidemic: A Break From The Past?, Hwee Kwan Chow, Keen Meng Choy

Research Collection School Of Economics

This paper aims to investigate whether the predictive ability and behaviour of professional forecasters are different during the Covid-19 epidemic as compared with the global financial crisis of 2008 and normal times. To this end, we utilise a survey of professional forecasters in Singapore collated by the central bank to analyse the forecasting record for GDP growth and CPI inflation. We first examine the point forecasts to document the extent of forecast failure in the pandemic crisis and test for behavioural explanations of the possible sources of forecast errors such as leader following and herding behaviour. Using percentile-based summary measures …


Challenges To Social Mobility In Singapore, Kong Weng Ho, Marcus Kheng Tat Tan Sep 2021

Challenges To Social Mobility In Singapore, Kong Weng Ho, Marcus Kheng Tat Tan

Research Collection School Of Economics

Singapore had achieved impressive economic growth together with a high level of upward mobility since her independence in 1965. However, the growth process might have become more uneven, in addition to diminishing growth for a matured economy like Singapore, which is also a highly open city state subject to competitive forces from other economies. Singapore has fared well recently,
evident from the 2020 social mobility findings reported by the World Economic Forum and the decline in Gini coefficients for the past decade. We discuss the education system in Singapore and the recently formed National Jobs Council, both important institutions for …


Government Support For Smes In Response To Covid-19: Theoretical Model Using Wang Transform, Shaun Shuxun Wang, Jing Rong Goh, Didier Sornette, He Wang, Esther Yang Jul 2021

Government Support For Smes In Response To Covid-19: Theoretical Model Using Wang Transform, Shaun Shuxun Wang, Jing Rong Goh, Didier Sornette, He Wang, Esther Yang

Research Collection School Of Economics

Purpose: Many governments are taking measures in support of small and medium-sized enterprises (SMEs) to mitigate the economic impact of the COVID-19 outbreak. This paper presents a theoretical model for evaluating various government measures, including insurance for bank loans, interest rate subsidy, bridge loans and relief of tax burdens. Design/methodology/approach: This paper distinguishes a firm's intrinsic value and book value, where a firm can lose its intrinsic value when it encounters cash-flow crunch. Wang transform is applied to (1) calculating the appropriate level of interest rate subsidy payable to incentivize banks to issue more loans to SMEs and to extend …


Government Management Capacities And The Containment Of Covid-19: A Repeated Cross-Sectional Study Across Chinese Cities, Wenchao Li, Jing Li, Junjian Yi Apr 2021

Government Management Capacities And The Containment Of Covid-19: A Repeated Cross-Sectional Study Across Chinese Cities, Wenchao Li, Jing Li, Junjian Yi

Research Collection School Of Economics

Objectives: Better understanding of the dynamics of the COVID-19 (2019 novel coronavirus disease) pandemic to curb its spread is now a global imperative. While travel restrictions and control measures have been shown to limit the spread of the disease, the effectiveness of the enforcement of those measures should depend on the strength of the government. Whether, and how, the government plays a role in fighting the disease, however, has not been investigated. Here, we show that government management capacities are critical to the containment of the disease. Setting: We conducted a statistical analysis based on cross-city comparisons within China. China …


Change In Outbreak Epicentre And Its Impact On The Importation Risks Of Covid-19 Progression: A Modelling Study, Oyelola A. Adegboye, Adeshina I. Adekunle, Anton Pak, Ezra Gayawan, Denis H. Y. Leung, Diana P. Rojas, Emma S. Mcbryde, Damon P. Eisen Mar 2021

Change In Outbreak Epicentre And Its Impact On The Importation Risks Of Covid-19 Progression: A Modelling Study, Oyelola A. Adegboye, Adeshina I. Adekunle, Anton Pak, Ezra Gayawan, Denis H. Y. Leung, Diana P. Rojas, Emma S. Mcbryde, Damon P. Eisen

Research Collection School Of Economics

Background: The outbreak of Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) that was first detected in the city of Wuhan, China has now spread to every inhabitable continent, but now the attention has shifted from China to other epicentres. This study explored early assessment of the influence of spatial proximities and travel patterns from Italy on the further spread of SARS-CoV-2 worldwide. Methods: Using data on the number of confirmed cases of COVID-19 and air travel data between countries, we applied a stochastic meta-population model to estimate the global spread of COVID-19. Pearson's correlation, semi-variogram, and Moran's Index were used to …


The Potential Impacts Of Covid-19 On The Global Value Chains: Gvc Positioning And Linkages, Gerald Foong, Pao-Li Chang Nov 2020

The Potential Impacts Of Covid-19 On The Global Value Chains: Gvc Positioning And Linkages, Gerald Foong, Pao-Li Chang

Research Collection School Of Economics

Apart from the public health crisis entailed by the Coronavirus Disease 2019 (COVID-19) pandemic, it has also propagated a pandemic-induced economic shock globally. One transmission channel is via the inter-country linkages arising from the trade in intermediate inputs, which is a pertinent characteristic of global value chains (GVCs), and resulting in a "supply-chain contagion" as termed by Baldwin and Tomiura (2020). In this paper, we propose measures of bilteral downstreamness and upstreamness, the extent of a country's GVC participation, and the position of a country in GVCs by leveraging upon the gross export decomposition framework as laid out by Borin …


Between Lives And Economy: Optimal Covid-19 Containment Policy In Open Economies, Wen-Tai Hsu, Hsuan-Chih Luke Lin, Yang Han Oct 2020

Between Lives And Economy: Optimal Covid-19 Containment Policy In Open Economies, Wen-Tai Hsu, Hsuan-Chih Luke Lin, Yang Han

Research Collection School Of Economics

This paper studies optimal containment policy for combating a pandemic in an open-economy context. It does so via quantitative analyses using a model that incorporates a standard epidemiological compartmental model in a multi-country, multi-sector Ricardian model of international trade with full-fledged input-output linkages. We devise a novel approach in computing optimal national policies in the long run, and contrast these policies with a baseline in which countries maintain their current policies until vaccine availability. The welfare gains under optimal policies are asymmetric as the gains for the set of countries which should tighten up the containment measures are much larger …


Spending Impact Of Covid-19 Stimulus Payments: Evidence From Card Transaction Data In South Korea, Kim, Kanghyock Koh, Wonjun Lyou Sep 2020

Spending Impact Of Covid-19 Stimulus Payments: Evidence From Card Transaction Data In South Korea, Kim, Kanghyock Koh, Wonjun Lyou

Research Collection School Of Economics

Various countries have implemented transfer programs to individuals since the Covid-19 outbreaks. However, the extent to which such transfers alleviate economic recessions is unclear. This paper analyzes a South Korean program, which provided vouchers redeemable only at small local businesses. We find that, due to the program, over 30% of households across all income groups increased their food and overall household spending, but the usage restriction may have affected consumer choice, distorting business competition. While the employment and sales of small businesses improved, the program’s fiscal sustainability is in question because of the large tax exemption.


Covid-19, Lockdown, And The Dynamics Of Subjective Well-Being, Terence C. Cheng, Kim, Kanghyock Koh Sep 2020

Covid-19, Lockdown, And The Dynamics Of Subjective Well-Being, Terence C. Cheng, Kim, Kanghyock Koh

Research Collection School Of Economics

We provide novel evidence on how the COVID-19 global health and economic crisis is affecting overall life satisfaction and domain-specific satisfaction using data from a monthly longitudinal survey of middle-aged and older Singaporeans. Using a difference-in-differences framework, we document large declines in overall life satisfaction and domain-specific satisfaction during the COVID-19 outbreak, except satisfaction with health. These declines coincide with the introduction of a nationwide lockdown, with life satisfaction remaining below its pre-pandemic levels even after the lockdown is lifted. We also find that individuals who report a drop in household income during the COVID-19 outbreak experience a decline in …
