Bayesian Methods In Economics And Finance: Editor's Introduction, Jun Yu

Research Collection School Of Economics

Modern days, Bayesian methods have gained prominence in theoretical work and applications in economics and finance due to the rapid development of computational technologies and their ability to learn. The special issue intends to examine central aspects in Bayesian analysis and applications, including prior choices, model selection with massive data and latent variables, hypothesis testing, Bayesian learning. In total, this special issue contains ten papers, all subject to the Journal of Econometrics (JOE)’s normal refereeing process. Most of these papers came from a conference held at the ESSEC Singapore campus on 10 December 2018.

Overnight Returns, Daytime Reversals, And Future Stock Returns, Ferhat Akbas, Ekkehart Boehmer, Chao Jiang, Paul D. Koch

Research Collection Lee Kong Chian School Of Business

A higher frequency of positive overnight returns followed by negative trading day reversals during a month suggests a more intense daily tug of war between opposing investor clienteles, who are likely composed of noise traders overnight and arbitrageurs during the day. We show that a more intense daily tug of war predicts higher future returns in the cross section. Additional tests support the conclusion that, in a more intense tug of war, daytime arbitrageurs are more likely to discount the possibility that positive news arrives overnight and thus overcorrect the persistent upward overnight price pressure.

Political Connections, Informational Asymmetry, And The Efficient Resolution Of Financial Distress, Madhav S. Aney, Sanjay Banerji

Research Collection School Of Economics

We show that securities issued by a distressed firm, often through exchange offers, providethe most efficient resolution of financial restructuring. Information asymmetry between thefirm-bank coalition and small bondholders gives rise to other forms of distress resolutionsuch as refinancing, public workout, and the inefficiency of liquidation. We find that politicallobbying by the firm-bank amplifies these inefficiencies and inhibits the development of privatemarket for distressed securities. Cross-country evidence is consistent with this and indicatesthat improved creditor rights, and information facilitating credit bureaus interact in reducingthe likelihood of inefficient distress resolution.

Skbi Big 5 Survey 2022 August, Singapore Management University

Sim Kee Boon Institute for Financial Economics

The latest survey results on the largest five economies (Big5) were revised markedly relative to the prior release (pre-Russia-Ukraine conflict), generally indicating weaker growth and higher inflation coupled with incremental ambiguity on the policy front.

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 …

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, …

The Imaginary And Epistemology Of Disaster Preparedness: The Case Of Japan's Nuclear Safety Failure, Hiro Saito

Research Collection School of Social Sciences

The Fukushima nuclear disaster was profoundly a man-made one, resulting from the organiza-tional failure of nuclear emergency preparedness. To fully understand the cause of this disaster, I propose to extend an organizational perspective on disasters into a macro-institutional perspec-tive on disaster preparedness. To this end, I borrow from science and technology studies the concepts of "sociotechnical imaginary" and "civic epistemology" to probe the deepest layers of meaning-making constitutive of disaster preparedness. I then apply these concepts to the history of nuclear energy in postwar Japan that was centered on the developmental state pursuing in-dustrial transformation. Specifically, I illustrate how the …

Efficient Bilateral Trade Via Two-Stage Mechanisms: Comparison Between One-Sided And Two-Sided Asymmetric Information Environments, Takashi Kunimoto, Cuiling Zhang

Research Collection School Of Economics

This paper first considers a bilateral-trade model with one-sided asymmetric information in which one agent (seller) initially owns an indivisible object and is fully informed of its value, while the other agent (buyer) intends to obtain the object whose value is unknown to himself. As no mechanisms can generally result in efficient, voluntary bilateral trades (Jehiel and Pauzner, 2006), we aim to overturn this impossibility result by employing two-stage mechanisms (Mezzetti, 2004) in which first, the outcome (e.g., allocation of the goods) is determined, then the agents observe their own outcome-decision payoffs, and finally, transfers are made. We show that …

Inflation Expectations Can Be A Self-Fulfilling Prophecy, Aurobindo Ghosh, Khyati Chauhan, Muskan Bagrodia

Research Collection Lee Kong Chian School Of Business

In a commentary, SMU Assistant Professor of Finance (Education) Aurobindo Ghosh, SMU postgraduate student and Research Assistant for the SInDEx Project Muskan Bagrodia and International Monetary Fund Economic Research Assistant Khyati Chauhan weighed in on why inflation expectations matter as much as economic data. They discussed how inflation expectations can be a self-fulfilling prophecy, and shared the key takeaways of the quarterly DBS-Sim Kee Boon Institute’s Singapore Index of Inflation Expectations (DBS-SKBI SInDEx) survey. They concluded that effective communication on inflation control measures, in addition to credible policy decisions, will help consumers feel assured and refrain from basing purchasing decisions …

The Cryptocurrency Participation Puzzle, Ran Duchin, David H. Solomon, Jun Tu, Xi Wang

Research Collection Lee Kong Chian School Of Business

We show that ongoing zero portfolio weights in cryptocurrency are surprisingly difficult to generate in a standard Bayesian portfolio theory framework. With ten years of prior data, equity market investors would need very pessimistic priors on mean returns to justify never having bought cryptocurrency: -10.6% per month for Bitcoin, and -19.6% per month for a diversified portfolio of cryptocurrencies. Moreover, most priors that involve never purchasing cryptocurrency imply that investors should short cryptocurrency. Optimal absolute weights are generally small but non-trivial (1-5%), frequently positive, and fairly smooth despite returns being volatile. Under a wide range of priors, the certainty equivalent …

The Exchange Rate System Reform In China: Some Important Results, Paul S. L. Yip, Yiu Kuen Tse, Yingjie Dong

Research Collection School Of Economics

We provide a review and empirical study on the exchange rate system reform in China. In the initial stage of the reform the Chinese central bank PBoC's implicit promise of gradual appreciation helped to contain the appreciation rate and volatility of the renminbi. Subsequently, under US pressure for faster appreciation and hence the PBoC's moderate violation of the implicit promise, there was a significant rise in the appreciation rate and the volatility of the renminbi. The moderate violation deteriorated further, forming a vicious cycle of speculative flows and faster exchange rate changes. Upon the onset of the global financial crisis …

International Asset Pricing With Strategic Business Groups, Massimo Massa, Hong Zhang, Hong Zhang

Research Collection Lee Kong Chian School Of Business

Firms in global markets often belong to business groups. We argue that this feature can have a profound influence on international asset pricing. In bad times, business groups may strategically reallocate risk across affiliated firms to protect core “central firms.” This strategic behavior induces co-movement among central firms, creating a new intertemporal risk factor. Based on a novel data set of worldwide ownership for 2002–2012, we find that central firms are better protected in bad times and that they earn relatively lower expected returns. Moreover, a centrality factor augments traditional models in explaining the cross section of international stock returns.

Customer Concentration And Corporate Carbon Emissions, Saiying Deng, Tinghua Duan, Frank Weikai Li, Xiaoling Pu

Research Collection Lee Kong Chian School Of Business

This paper examines whether economic links with major corporate customers curb corporate carbon emissions. We show that supplier firms with a concentrated customer base have significantly lower carbon emissions. The baseline results are robust to alternative measures of carbon emissions and customer concentration, and various approaches that mitigate endogeneity concerns due to omitted variables and reverse causality. Moreover, the curbing effect of customer concentration on supplier carbon emissions is more pronounced in firms facing lower customer switching costs, with less (more) supplier (customer) bargaining power, fewer redeployable assets, operating in more carbon-intensive industries, and after the Paris Agreement of 2015. …

The Embodiment Controversy: On The Policy Implications Of Vintage Capital Models, Roberto M. Samaniego, Juliana Yu Sun

Research Collection School Of Economics

We explore the long-run impact of policy on the level of economic activity through changes in the vintage distribution of capital, in a model where different vintages coexist in production. Because firms can choose the vintage of capital in which they invest, investment subsidies do not affect the vintage structure of capital. In contrast, vintage-specific taxes or subsidies that target the newest vintages of capital can significantly affect output and welfare in the long run, mainly downward. Transition dynamics are rapid, so that steady-state comparisons give an accurate picture of the welfare impact of vintage tax wedges.

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 …

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.

Labor Market Implications Of Taiwan’S Accession To The Wto: A Dynamic Quantitative Analysis, Pao-Li Chang, Yi-Fan Chen, Wen-Tai Hsu, Xin Yi

Research Collection School Of Economics

We study the effects of Taiwan’s accession to the WTO in 2002 on the labor market dynamics in Taiwan during 1995–2020. Based on the dynamic hat algebra of Caliendo, Dvorkin and Parro (2019), we modify the framework to allow for differently skilled labor inputs (low, middle, high) and sector-skill dynamic choice by workers. We map the model to the labor-market transition data in Taiwan (based on quasi-longitudinal household surveys), the country-sector-specific skill shares in production, and the bi-lateral trade flows and import tariffs, for 61 economies and 22 sectors for the period 1995–2007. We study the counterfactual dynamics if the …

Externalities In The Housing Market And Agglomeration Economies, Yifan Wu

Dissertations and Theses Collection (Open Access)

This thesis studies the externalities in the housing market and agglomeration economies. While knowledge-based externalities, or knowledge spillovers are one of the most important micro-foundations of agglomeration economies, the first chapter studies how knowledge spillovers from universities affect local innovation activities. In the second chapter, we propose a high-order spatiotemporal autoregression approach to study the externalities in the housing market. The third chapter studies another important but under explored aspect of the agglomeration economies – the role that marriage market plays in providing incentives to promote urbanization, along with the unique feminization phenomenon during this process.

The first chapter studies …

Attenuation Of Agglomeration Economies: Evidence From The Universe Of Chinese Manufacturing Firms, Li Jing, Liyao Li, Shimeng Liu

Research Collection School Of Economics

This paper quantifies industry-specific spatial attenuation of agglomeration economies by taking advantage of unique geocoded administrative data on the universe of Chinese manufacturing firms. The estimates of industry-level attenuation speed further allow us to systematically assess the goodness of fit of various spatial decay functional forms and to evaluate the micro-foundations that govern the decay patterns across industries. We obtain three main findings. First, agglomeration spillovers attenuate by about 90 percent on average from 0-1 km to 1-5 km in China, with large heterogeneity in the extent of attenuation ranging from 73 percent to 116 percent across industries. Second, the …

Oil Price Shocks And Stock Market Anomalies, Zhaobo Zhu, Licheng Sun, Jun Tu, Qiang Ji

Research Collection Lee Kong Chian School Of Business

This paper provides a novel perspective to the nexus of oil prices and stock markets by examining the impact of oil price shocks on stock market anomalies. After decomposing oil price shocks into three types , we find that aggregate demand shocks have the strongest influence on stock market anomalies. In contrast, oil supply shocks and oil-specific demand shocks have little impact. Similar results are also found in the industry analysis. Interestingly, the link between aggregate demand shocks and anomalies is the strongest among firms with either small size or high idiosyncratic risks. The documented effects are robust after controlling …

Why Do U.S. Firms Invest Less Over Time?, Fangjian Fu, Sheng Huang, Rong Wang

Research Collection Lee Kong Chian School Of Business

Capital expenditures of U.S. public firms, relative to total assets, decrease by more than half from 1980 to 2020. The decline is pervasive across industries and firms of different characteristics and cannot be explained by the usual determinants of investment and many other seemingly plausible reasons. The decline is consistent with the transformation in production technology — firms rely more on intangible capital and less on fixed assets in production. Industry-level analyses yield supporting evidence. We observe similar declining trend in capital expenditure in other developed countries but not in most emerging markets.

Eradicating Malaria: Innovation Diffusion In The Face Of Grand Challenges, Han Jiang, Hao Liang, Dongning Yang

Research Collection Lee Kong Chian School Of Business

What is the role of organizational innovation—beyond technological innovation—in an era of grand challenges concerning health, poverty, and economic development around the world? How is organizational innovation developed and diffused to influence resource allocation in the field? We conduct a qualitative case study by analyzing a Chinese pharmaceutical firm’s efforts to combat malaria in Africa over 10 years. Through documentation and extensive interviews, we study the role of innovation diffusion and resource allocation to address grand challenges in emerging markets with significant institutional voids. Our conceptual model delineates the different stages of innovation diffusion to show how organizations can draw …

What, Why And How Financial Development Matters: Evidence Of Asean-5, Asia-5 And Oecd-7 Economies, Swee Liang Tan

Research Collection School Of Economics

This paper analyzed the association between bank and capital markets financial development with income per capita in three regions; ASEAN-5 economies (Singapore, Malaysia, Thailand, Philippines, Indonesia), Asia-5 (Japan, China, Hong Kong SAR, South Korea, and India), and OECD-7 (Australia, Canada, Denmark, Norway, Sweden, UK, and US) from 2000 to 2017 using panel data regressions. A key lesson ASEAN-5 can learn from Asia-5 and OECD-7 experience is that bank size does matter despite digital disruptions to their banking system; yet large financial structure that favors banks is negatively associated with Asia-5, and importantly, efficient banking system (not bank size alone) is …

Spatial Panel Data Models: Unbalanced Panel, Threshold Effect And Network Structure, Xiaoyu Meng

Dissertations and Theses Collection (Open Access)

This thesis studies the estimation and inference problems for spatial panel data models when the panels are unbalanced, when the panels contain threshold effects, or when the panels contain time-varying network structures. These three scenarios divide the thesis naturally into three chapters.

The first chapter considers estimation and inferences for fixed effects spatial panel data models based on unbalanced panels that result from randomly missing spatial units. The unbalanced nature of the panel data renders the standard method of estimation inapplicable. In this chapter, we proposed an M-estimation method where the estimating functions are obtained by adjusting the concentrated quasi …

Essays On Social Choice And Implementation Theory, Paulo Daniel Salles Ramos

Dissertations and Theses Collection (Open Access)

We present here three essays. The first two are about Social Choice Theory and explore under what domain restrictions is possible to obtain a Social Choice Function that is Well Behaved as well as Monotonic, and what other characteristics can be inferred about such functions on that domain. The last essay is about Implementation Theory and explore how to obtain a more compelling form of implementation than pure Nash Equilibrium for finite environments using finite mechanisms.

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 …

Bayesian And Machine Learning Methods With Applications In Asset Pricing, Yaohan Chen

Dissertations and Theses Collection (Open Access)

The dissertation consists of three essays on asset pricing by constructing new data set and developing new methodologies. In the first chapter, we conduct empirical studies on the volatility-managed portfolios in the Chinese stock market. Using data from the Chinese stock market, we have found that the main empirical findings in Moreira and Muir (2017) break down. Based on the empirical findings, we exploit a comprehensive set of $99$ equity strategies in the Chinese stock market to analyze the value of managed portfolios. Based on these $99$ equity trading strategies, we find that there exists no systematic gain from scaling …

Essays On Long Memory Time Series And Panel Models, Shuyao Ke

Dissertations and Theses Collection (Open Access)

This dissertation studies different long memory models. The first chapter considers a time series regression model where both the regressors and error term are locally stationary long memory processes with time-varying memory parameters, and the regression coefficients are also allowed to be time-varying. We consider a frequency-domain least squares estimator with kernelized discrete Fourier transform and derive its pointwise asymptotic normality and uniform consistency. A specification test on the constancy of coefficients is provided. The second chapter studies a linear regression panel data model with interactive fixed effects where the regressors, factors and idiosyncratic error terms are all stationary but …
