Mildly Explosive Autoregression With Anti-Persistent Errors, Yui Lim Lui, Jun Yu, Jun Yu

Research Collection School Of Economics

An asymptotic distribution is derived for the least squares (LS) estimate of a first-order autoregression with a mildly explosive root and anti-persistent errors. While the sample moments depend on the Hurst parameter asymptotically, the Cauchy limiting distribution theory remains valid for the LS estimates in the model without intercept and a model with an asymptotically negligible intercept. Monte Carlo studies are designed to check the precision of the Cauchy distribution in finite samples. An empirical study based on the monthly NASDAQ index highlights the usefulness of the model and the new limiting distribution.

Spatial Dynamic Panel Data Models With Correlated Random Effects, Liyao Li, Zhenlin Yang

Research Collection School Of Economics

In this paper, M-estimation and inference methods are developed for spatial dynamic panel data models with correlated random effects, based on short panels. The unobserved individual-specific effects are assumed to be correlated with the observed time-varying regressors linearly or in a linearizable way, giving the so-called correlated random effects model, which allows the estimation of effects of time-invariant regressors. The unbiased estimating functions are obtained by adjusting the conditional quasi-scores given the initial observations, leading to M-estimators that are consistent, asymptotically normal, and free from the initial conditions except the process starting time. By decomposing the estimating functions …

Connecting Care Chains And Care Diamonds: The Elderly Care Skills Regime In Singapore, Yasmin Y. Ortiga, Kellyn Wee, Brenda S. A. Yeoh

Research Collection School of Social Sciences

Research on the globalization of care work often faces the persistent challenge of building meaningful connections between the movement of care labour at a global scale and place-based frameworks of care access and delivery. In addressing this gap in this article, we propose to take a closer look at how the care-migration nexus produces 'ideal' care workers through a skills regime. Based on the case of elderly care in Singapore, in this article, we demonstrate how state institutions and private agencies attempts to fill local labour needs by producing care workers among both Singapore citizens and migrant women. This leads …

The United States And The "Chinese Problem" Of Southeast Asia, Wen-Qing Ngoei

Research Collection School of Social Sciences

This essay examines how US Cold War policy toward all of Southeast Asia arose from American suspicions that the region's Chinese diaspora would align itself with the Chinese communists against the west. In so doing, it explores how US distrust of the Chinese diaspora fell in step with a longer imperialist tradition practised not only by the European powers for centuries, but also the Japanese Empire during its brief ascendancy during World War Two. Additionally, the essay proposes that to move beyond the bilateral studies that dominate the histories of US-Southeast Asian relations to view the region as whole, it …

The Intrinsic Values Of Confucian Democracy And Dewey's Pragmatist Method, Sor-Hoon Tan

Research Collection School of Social Sciences

Given the historical association of Confucianism, or rather the Ru school of thought, with autocratic government since the Han dynasty, one of the challenges for contemporary scholars of Confucianism is to interpret and reconstruct Confucianism to guard against authoritarian tendencies without surrendering its distinctive ethical-political vision. Confucianism is incompatible with the conventional understanding of democracy as liberal democracy best represented by the United States, focused on limiting government with checks and balances, prioritizing protection of the civil and political rights of individuals, regular elections of representatives in which partisan competition for power offers citizens very little real choice, and it …

Rural China Under The Covid‐19 Pandemic: Differentiated Impacts, Rural–Urban Inequality And Agro‐Industrialization, Forrest Q. Zhang, Zhanping Hu

Research Collection School of Social Sciences

We use field data collected in a village in northern China to examine the impacts of the COVID‐19 pandemic on rural economy and livelihoods. The lockdown effectively protected the village from the pandemic, resulting in zero infection. The economic impacts were mostly negative but differentiated across economic sectors and livelihood strategies; some gained from the business opportunities arising from the pandemic. Wage loss for migrant workers was the most common negative impact but lasted less than 2 months. Overall, rural China has escaped the worst impacts of the pandemic found in other developing countries. We argue that the structure of …

Beliefs And Social Norms As Precursors Of Environmental Support: The Joint Influence Of Collectivism And Socioeconomic Status, David K. Sherman, John A. Updegraff, Michelle S. Handy, Kimin Eom, Heejung S. Sim

Research Collection School of Social Sciences

The present research investigates how the cultural value of collectivism interacts with socioeconomic status (SES) to influence the basis of action. Using a U.S. national sample (N = 2,538), the research examines how these sociocultural factors jointly moderate the strength of two precursors of environmental support: beliefs about climate change and perceived descriptive norms. SES and collectivism interacted with climate change beliefs such that beliefs predicted environmental support (i.e., proenvironmental behaviors and policy support) more strongly for those who were high in SES and low in collectivism than for all other groups. This interaction was explained, in part, by sense …

Covid-19 Pandemic And Opportunities For Digitalisation Of Smes, Yuanto Kusnadi, Gary Pan

Perspectives@SMU

The Covid-19 pandemic has brought about disruptions in all sectors of economy. With lockdown being implemented in most of the countries around the world, it has necessitated changes in the business models of SMEs. A glaring area of business opportunity focuses on online business. For instance, retailers who do not yet have an online presence or have not been paying much attention to conducting sales online were caught off-guard during the circuit breaker period which has resulted in decreased footfall and plummeting sales in most physical stores. Therefore, having an online retail presence has become critical for businesses, as they …

Haptic Heritage And The Paradox Of Provenance Within Singapore's Cottage Food Businesses, Orlando Woods, John A. Donaldson

Research Collection School of Social Sciences

This paper offers a “more-than-representational” understanding of how heritage value is reproduced by cottage food businesses in Singapore. It advances the notion of haptic heritage to highlight the importance of touch and feel in inculcating food with a sense of heritage value. Haptic heritage is reproduced through the physical handling of ingredients in ways that contribute to more “authentic” products. However, it also foregrounds food production processes that are more tactile, time-consuming and thus unscalable than their automated counterparts. Accordingly, the reproduction of haptic heritage is becoming increasingly unviable in Singapore’s competitive economic landscape. These ideas are explored through a …

The Role Of Macroeconomic And Policy Uncertainty In Density Forecast Dispersion, You Li, Anthony S. Tay

Research Collection School Of Economics

We explore empirically the role of macroeconomic and policy uncertainty in explaining dispersion in professional forecasters’ density forecasts, and in explaining individual forecaster uncertainty (defined as the uncertainty expressed by individual forecasters in their density forecasts). We focus on US real output growth and inflation, using data from the Philadelphia Fed’s quarterly Survey of Professional Forecasters (SPF), 1992-2016. We find that dispersion in individual density forecasts is related to macroeconomic uncertainty, especially in longer horizon forecasts, but not policy or forecaster uncertainty. There is also little evidence that forecaster uncertainty reflects macroeconomic or policy uncertainty.

“Data is the new oil”. Just like oil, which powered the economy in the last century, data are what moves the world today. This is especially true for international trade. The crucial role played by data can be observed at every step of the process, from the conception of a new product and the sourcing of raw materials and parts, to the manufacturing process and the transportation of products across borders, until they finally reach the hands of consumers from every corner of the world.

Tax Avoidance By Professionals: Where Are We With Wee Teng Yau?, Vincent Ooi

Research Collection Yong Pung How School Of Law

Wee Teng Yau represents the first case on tax avoidance by professionals to come before the Supreme Court. This note attempts to reconcile the judgments of the High Court and the Income Tax Board of Review, which both made findings that the taxpayer had engaged in tax avoidance, but which approached the case rather differently on some points. Apart from a clear rejection of the “personal exertion” principle as having no legal basis under Singapore law, it appears that the common conclusion is that professionals incorporating a company would not constitute tax avoidance in itself, but if this was coupled …

Wto Reform: A China Round, Henry S. Gao

Research Collection Yong Pung How School Of Law

Since its accession to the World Trade Organization (WTO), China's exports have been growing exponentially. In 2009, China became the world's top goods exporter. Four years later, China unseated the United States as the top trading nation in the world. In contrast to the burgeoning Chinese economy, the United States and Europe have been suffering from economic decline since the global financial crisis in 2008. China regards its rise as a long overdue restoration of its rightful position, as it has been the largest economy in the world for most of its history, except the brief aberration over the past …

The Effects Of Income On Health: Evidence From Lottery Wins In Singapore, Seonghoon Kim, Kanghyock Koh

Research Collection School Of Economics

We estimate the causal effects of household income on self-reported health status by exploiting random variations in the amount of lottery prizes won. We find that a S$10,000 (US$7,245) increase in income via lottery wins improves individuals’ health by a standard deviation of 0.18. As possible mechanisms, we find that lottery wins increase household consumption spending and improve overall life satisfaction, but do not change healthcare spending, labor supply, and risky health behavior. Previous studies, which focused on the health effects of lottery prizes in Western European countries with strong social safety nets, do not find positive effects other than …

"Doing It For The 'Gram?" The Representational Politics Of Popular Humanitarianism, Orlando Woods, Siew Ying Shee

Research Collection School of Social Sciences

This paper explores how digital photography – the practice of taking pictures and sharing them via social media – can give rise to representational politics. These politics are pronounced when disadvantaged people and places are the objects of digital representation, as they become (dis)empowered by being implicated in the affective economy of difference. Empirically, we examine the representational practices that Singaporean voluntourists, and companies that organise overseas humanitarian projects, engage in. We highlight how their motivations for engaging with these projects can be obfuscated by the opportunity to generate influence on Instagram, which can then shape the practice of popular …

Is There Evidence For Cross-Domain Congruency Sequence Effect? A Replication Of Kan Et Al. (2013), Balazs Aczel, Marton Kovacs, Miklos Bognar, Bence Palfi, Andree Hartanto, Sandersan Onie, Lucas E. Tiong, Thomas Rhys Evans

Research Collection School of Social Sciences

Exploring the mechanisms of cognitive control is central to understanding how we control our behaviour. These mechanisms can be studied in conflict paradigms, which require the inhibition of irrelevant responses to perform the task. It has been suggested that in these tasks, the detection of conflict enhances cognitive control resulting in improved conflict resolution of subsequent trials. If this is the case, then this so-called congruency sequence effect can be expected to occur in cross-domain tasks. Previous research on the domaingenerality of the effect presented inconsistent results. In this study, we provide a multi-site replication of three previous experiments of …

Looking Back On Asean And The Sino-Us Rivalry In The Cold War, Wen-Qing (Wei Wenqing) Ngoei

Research Collection School of Social Sciences

In discussions of the current Sino-US rivalry, talk of China eclipsing America as the world’s foremost power is popular. Analysts seeking signs of US decline can certainly muster suitable evidence with which to argue this case. In Southeast Asia, a major theatre of Sino-US competition for influence, trade and security ties, there are serious concerns over which of the two powers will end up predominant in regional affairs. In fact, America and its Southeast Asian allies faced a similar challenge in the Cold War. Then as now, most of the attention was on the big powers. But, the agency of …

Tree Effects On Urban Microclimate: Diurnal, Seasonal, And Climatic Temperature Differences Explained By Separating Radiation, Evapotranspiration, And Roughness Effects, Naika Meili, Gabriele Manoli, Paolo Burlando, Jan Carmeliet, Winston T. L. Chow, Andres M. Coutts, Matthias Roth, Erik Velasco, Enrique R. Vivoni, Simone Fatichi

Research Collection School of Social Sciences

Increasing urban tree cover is an often proposed mitigation strategy against urban heat as trees are expected to cool cities through evapotranspiration and shade provision. However, trees also modify wind flow and urban aerodynamic roughness, which can potentially limit heat dissipation. Existing studies show a varying cooling potential of urban trees in different climates and times of the day. These differences are so far not systematically explained as partitioning the individual tree effects is challenging and impossible through observations alone. Here, we conduct numerical experiments removing and adding radiation, evapotranspiration, and aerodynamic roughness effects caused by urban trees using a …
