An Ai Approach To Measuring Financial Risk, Lining Yu, Wolfgang Karl Hardle, Lukas Borke, Thijs Benschop Dec 2019

An Ai Approach To Measuring Financial Risk, Lining Yu, Wolfgang Karl Hardle, Lukas Borke, Thijs Benschop

Sim Kee Boon Institute for Financial Economics

AI artificial intelligence brings about new quantitative techniques to assess the state of an economy. Here, we describe a new measure for systemic risk: the Financial Risk Meter (FRM). This measure is based on the penalization parameter (λ" role="presentation" style="box-sizing: border-box; display: inline; font-style: normal; font-weight: normal; line-height: normal; font-size: 18px; text-indent: 0px; text-align: left; text-transform: none; letter-spacing: normal; word-spacing: normal; overflow-wrap: normal; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; border: 0px; padding: 0px; margin: 0px; position: relative;">λλ) of a linear quantile lasso regression. The FRM is calculated by taking the average …

The Unexpected Activeness Of Passive Investors: A Worldwide Analysis Of Etfs, Si Cheng, Massimo Massa, Hong Zhang Dec 2019

The Unexpected Activeness Of Passive Investors: A Worldwide Analysis Of Etfs, Si Cheng, Massimo Massa, Hong Zhang

Research Collection Lee Kong Chian School Of Business

The global ETF industry provides more complicated investment vehicles than low-cost index trackers. Instead, we find that the real investments of ETFs may deviate from their benchmarks to leverage informational advantages (which leads to a surprising stock-selection ability) and to help affiliated OEFs through cross-trading. These effects are more prevalent in ETFs domiciled in Europe. Moreover, ETF flows seem to respond to additional risk. These results have important normative implications for consumer protection and financial stability. (JEL G20)

From Actions To Paths To Patterning: Toward A Dynamic Theory Of Patterning In Routines, Kenneth T. Goh, Brian T. Pentland Dec 2019

From Actions To Paths To Patterning: Toward A Dynamic Theory Of Patterning In Routines, Kenneth T. Goh, Brian T. Pentland

Research Collection Lee Kong Chian School Of Business

This paper demonstrates a new way of seeing and theorizing about the dynamics of organizational routines through the concept of paths – time-ordered sequences of actions or events in performing work. Empirically and conceptually, paths provide the missing link between specific actions and patterns of action. When routines are represented as a narrative network, tracing the formation and dissolution of action paths can generate new insights about the dynamic patterning of actions in routine performances. We traced action paths using longitudinal field data from a videogame development project and found that action patterns change dramatically over time based on the …

Optimal Control For Transboundary Pollution Under Ecological Compensation: A Stochastic Differential Game Approach, Ke Jiang, Ryan Knowles Merrill, Daming You, Pan Pan Dec 2019

Optimal Control For Transboundary Pollution Under Ecological Compensation: A Stochastic Differential Game Approach, Ke Jiang, Ryan Knowles Merrill, Daming You, Pan Pan

Research Collection Lee Kong Chian School Of Business

To account for previously ignored, yet widely observed uncertainty in nature's capability to replenish the natural environment in ways that should inform ideal design of ecological compensation (EC) regimes, this study constructs a stochastic differential game (SDG) model to analyze transboundary pollution control options between a compensating and compensated region. Equilibrium strategies in the stochastic, two player game inform optimal control theory and reveal a welfare distribution mechanism to form the basis of an improved cooperative game contract. A case-based numerical example serves to verify the theoretical results and supports three key insights. First, accounting for various random disturbance factors, …

Riding The Blockchain Mania: Public Firms’ Speculative 8-K Disclosures, Pengkai Lin Dec 2019

Riding The Blockchain Mania: Public Firms’ Speculative 8-K Disclosures, Pengkai Lin

Research Collection School Of Accountancy

This paper provides evidence on public firms' initial 8-K disclosures that mention Blockchain and investors' response to these disclosures. We categorize the description of Blockchain activities in firms' 8-Ks as Speculative (e.g., a vague future plan that involves Blockchain) or Existing (e.g., a description of Blockchain product). We document a sharp increase in the number of initial 8-K disclosures of Blockchain, particularly by Speculative firms, coinciding with the rise of Bitcoin prices and excitement in Blockchain technology in the last quarter of 2017. Investors react positively to the Blockchain 8-Ks issued by Speculative firms in the initial seven-day event window …

Do Real Estate Agents Have Information Advantages In Housing Markets?, Sumit Agarwal, Jia He, Tien Foo Sing, Changcheng Song Dec 2019

Do Real Estate Agents Have Information Advantages In Housing Markets?, Sumit Agarwal, Jia He, Tien Foo Sing, Changcheng Song

Research Collection Lee Kong Chian School Of Business

We use a large housing transaction data set in Singapore to study whether real estate agents use information advantages to buy houses at bargain prices. Agents bought their own houses at prices that are 2.54% lower than comparable houses bought by other buyers. Consistent with information asymmetries, agent buyers have more information advantages in less informative environments, and agent buyers are more likely to buy houses from agent sellers. Agent discounts are from both “cherry picking” and bargaining power, and bargaining power contributes more to the agent discounts. Agents’ advantage consists in their information of available houses and previous purchase …

Urban Consolidation Center Or Peer-To-Peer Platform? The Solution To Urban Last-Mile Delivery, Qiyuan Deng, Xin Fang, Yun Fong Lim Dec 2019

Urban Consolidation Center Or Peer-To-Peer Platform? The Solution To Urban Last-Mile Delivery, Qiyuan Deng, Xin Fang, Yun Fong Lim

Research Collection Lee Kong Chian School Of Business

Booming e-commerce activities further increase this demand, exerting intense pressure on the cities' well-being. To build a city with congestion and pollution under control, a consolidator can operate an urban consolidation center (UCC) to bundle shipments from multiple carriers before the last-mile delivery. Alternatively, the consolidator can operate a peer-to-peer platform for the carriers to share their delivery capacity. Our objective is to compare the performance of these two business models. Under each business model, we study the interactions between a consolidator and multiple carriers using a two-period game-theoretical model. In each period, the consolidator first chooses a delivery fee …

Machine Learning Using Instruments For Text Selection: Predicting Innovation Performance, Kian Guan Lim, Michelle S. J. Lim Dec 2019

Machine Learning Using Instruments For Text Selection: Predicting Innovation Performance, Kian Guan Lim, Michelle S. J. Lim

Research Collection Lee Kong Chian School Of Business

In machine learning we utilize the idea of employing instrumental variable such as patent records to train the texts. Patent records are highly correlated with R&D expenditures, but are not necessarily correlated with performance residuals not linked to R&D. Thus, using instrumental patent records to train word counts of selected texts to serve as a proxy for firm R&D expenditure, we show that the texts and associated word counts provide effective prediction of firm innovation performances such as firm market value and total sales growth.

Chief Financial Officer Demographic Characteristics And Fraudulent Financial Reporting In China, Jinghui Sun, Pamela Kent, Baolei Qi, Jiwei Wang Dec 2019

Chief Financial Officer Demographic Characteristics And Fraudulent Financial Reporting In China, Jinghui Sun, Pamela Kent, Baolei Qi, Jiwei Wang

Research Collection School Of Accountancy

We investigate whether management's cognitions, values and perceptions are associated with fraud for 18 863 firm-years for Chinese listed firms from 2000 to 2014. Demographic characteristics of the chief financial officer (CFO) are used as proxies for management's cognitions, values and perceptions. We find that fraudulent financial reporting is higher when CFOs are younger, male, and have lower education backgrounds. An analysis of inflated earnings, fictitious assets, material omissions and other material misstatements provide similar results, with the exception that CFOs with higher education levels are associated with more inflated earnings.

Long-Term Index Fund Ownership And Stock Returns, Ekkehart Boehmer, Wanshan Song, Ashish Tiwari, Zhe Zhang Dec 2019

Long-Term Index Fund Ownership And Stock Returns, Ekkehart Boehmer, Wanshan Song, Ashish Tiwari, Zhe Zhang

Research Collection Lee Kong Chian School Of Business

We examine the implications of stock ownership by index funds for shareholder value. Consistent with recent findings that stock ownership by passive funds contributes to improved governance, we document a strong positive relation between the duration of passive fund holdings and subsequent stock performance. This positive relation is more pronounced for firms with recent poor performance, and for smaller firms and firms with higher allocation weights in passive funds’ portfolios. Our results support the view that index funds, although passive in their investment decisions, successfully contribute to long-term value creation by actively engaging with firms on matters of governance.

Online Content Consumption: Social Endorsements, Observational Learning And Word-Of-Mouth, Qian Tang, Tingting Song, Liangfei Qiu, Ashish Agarwal Dec 2019

Online Content Consumption: Social Endorsements, Observational Learning And Word-Of-Mouth, Qian Tang, Tingting Song, Liangfei Qiu, Ashish Agarwal

Research Collection School Of Computing and Information Systems

The consumption of online content can occur through observational learning (OL) whereby consumers follow previous consumers’ choices or social endorsement (SE) wherein consumers receive content sharing from their social ties. As users consume content, they also generate post-consumption word-of-mouth (WOM) signals. OL, SE and WOM together shape the diffusion of the content. This study examines the drivers of SE and the effect of SE on content consumption and post-consumption WOM. In particular, we compare SE with OL. Using a random sample of 8,945 new videos posted on YouTube, we collected a multi-platform dataset consisting of data on video consumption and …

Chasing Private Information, Marcin Kacperczyk, Emiliano Sebastian Pagnotta Dec 2019

Chasing Private Information, Marcin Kacperczyk, Emiliano Sebastian Pagnotta

Research Collection Lee Kong Chian School Of Business

Using over 5,000 trades unequivocally based on nonpublic information about firm fundamentals, we find that asymmetric information proxies display abnormal values on days with informed trading. Volatility and volume are abnormally high, whereas illiquidity is low, in equity and option markets. Daily returns reflect the sign of private signals, but bid-ask spreads are lower when informed investors trade. Market makers' learning under event uncertainty and limit orders help explain these findings. The cross-section of information duration indicates that traders select days with high uninformed volume. Evidence from the U.S. SEC Whistleblower Reward Program and the FINRA involvement addresses selection concerns.

Climbing The Corporate Ladder And Within-Person Changes In Narcissism: Reciprocal Relationships Over Two Decades, Bart Wille, Joeri Hofmans, Filip Lievens, Mitja D. Back, Filip De Fruyt Dec 2019

Climbing The Corporate Ladder And Within-Person Changes In Narcissism: Reciprocal Relationships Over Two Decades, Bart Wille, Joeri Hofmans, Filip Lievens, Mitja D. Back, Filip De Fruyt

Research Collection Lee Kong Chian School Of Business

Prior research demonstrated that narcissism fosters the attainment of higher managerial ranks in organizations. However, it is not known whether climbing the corporate ladder also fosters the development of narcissism over time. Whereas prior work consistently adopted a unidirectional perspective on narcissism and career attainment, this study presents and tests a bidirectional perspective, incorporating long-term development in narcissism in relation to and in response to long-term upward mobility. To this end, a cohort of highly educated professionals was assessed three times over a 22-year time frame. Extended latent difference score modeling showed that, over the entire interval, within-person changes in …

Of Promoting Networking And Protecting Privacy: Effects Of Defaults And Regulatory Focus On Social Media Users’ Preference Settings, Hichang Cho, Sungjong Roh, Byungho Park Dec 2019

Of Promoting Networking And Protecting Privacy: Effects Of Defaults And Regulatory Focus On Social Media Users’ Preference Settings, Hichang Cho, Sungjong Roh, Byungho Park

Research Collection Lee Kong Chian School Of Business

Privacy research has debated whether privacy decision-making is determined by users' stable preferences (i.e., individual traits), privacy calculus (i.e., cost-benefit analysis), or “responses on the spot” that vary across contexts. This study focuses on two factors—default setting as a contextual factor and regulatory focus as an individual difference factor—and examines the degree to which these factors affect social media users' decision-making when using privacy preference settings in a fictitious social networking site. The results, based on two experimental studies (study 1, n = 414; study 2, n = 213), show that default settings significantly affect users' privacy preferences, such that …

Center Of Volume Mass: Does Options Trading Predict Stock Returns?, Gennaro Bernile, Fei Gao, Jianfeng Hu Dec 2019

Center Of Volume Mass: Does Options Trading Predict Stock Returns?, Gennaro Bernile, Fei Gao, Jianfeng Hu

Research Collection Lee Kong Chian School Of Business

We examine whether the distribution of trades along the set of strike prices of option contracts on the same stock contains information about underlying price discovery. We show that option traders' demand for delta exposure drives the volume-weighted average strike-spot price ratio (VWKS). In turn, we find that VWKS predicts underlying returns and anticipates the flow of fundamental information about the stock. The return predictability is greater but not limited to stocks with higher information asymmetries and arbitrage costs, and becomes stronger ahead of value relevant news. Overall, options trading appears to play an important informational role for underlying markets.

本稿では，日本版スチュワードシップコードの改訂により始まった機関投資家 による議決権行使の結果について，投資家のタイプごとに分析し，どのような投 資家がどのような会社提案議案についてより多くの反対票を投じているかについ て検討した。先行研究に従えば，資産運用会社のように投資先企業とアームズレ ングスの関係を持つ投資家は，保険会社のように投資先企業とビジネス上の関係 を持つ投資家と比較すると，会社側提案に対して異議を唱える可能性が高いとさ れる。また，株式持ち合いなど日本的背景を考慮すると，日本においては，外資 系投資家の方が国内の投資家に比べて，会社提案に対して反対票を投じる可能性 が高いことも予想される。2018年度の議決権行使の結果を分析したところ，ほぼ 先行研究と同じ結果が得られ，業種で分類した場合，資産運用会社の方が生損保 のような保険会社より反対票の比率が高いこと，資本国籍で分類すると，外資投 資家の方が買収防衛策の導入や退任役員への退職慰労金の支給など特定の項目に ついて，日系の投資家に比べて反対率が高いことが確認された。

Leader Mindfulness And Employee Performance: A Sequential Mediation Model Of Lmx Quality, Interpersonal Justice, And Employee Stress, Jochen Reb, Sankalp Chaturvedi, Jayanth Narayanan, Ravi S. Kudesia Dec 2019

Leader Mindfulness And Employee Performance: A Sequential Mediation Model Of Lmx Quality, Interpersonal Justice, And Employee Stress, Jochen Reb, Sankalp Chaturvedi, Jayanth Narayanan, Ravi S. Kudesia

Research Collection Lee Kong Chian School Of Business

In the present research, we examine the relation between leader mindfulness and employee performance through the lenses of organizational justice and leader-member relations. We hypothesize that employees of more mindful leaders view their relations as being of higher leader-member exchange (LMX) quality. We further hypothesize two mediating mechanisms of this relation: increased interpersonal justice and reduced employee stress. In other words, we posit that employees of more mindful leaders feel treated with greater respect and experience less stress. Finally, we predict that LMX quality serves as a mediator linking leader mindfulness to employee performance—defined in terms of both in-role and …

Peer Effects Of Corporate Social Responsibility, Jie Cao, Hao Liang, Xintong Zhan Dec 2019

Peer Effects Of Corporate Social Responsibility, Jie Cao, Hao Liang, Xintong Zhan

Research Collection Lee Kong Chian School Of Business

We investigate how firms react to their product-market peers' commitment to and adoption of corporate social responsibility (CSR) using a regression discontinuity design approach. Relying on the passage or failure of CSR proposals by a narrow margin of votes during shareholder meetings, we find the passage of a close-call CSR proposal and its implementation are followed by the adoption of similar CSR practices by peer firms. In addition, peers that have greater difficulty in catching up with the voting firm in CSR experience significantly lower stock returns around the passage, consistent with the notion that the spillover effect of the …

Regulations And Brain Drain: Evidence From Wall Street Star Analysts’ Career Choices, Yuyan Guan, Congcong Li, Hai Lu, Franco Wong Dec 2019

Regulations And Brain Drain: Evidence From Wall Street Star Analysts’ Career Choices, Yuyan Guan, Congcong Li, Hai Lu, Franco Wong

Research Collection School Of Accountancy

The Global Settlement, along with related regulations in the early 2000s, prohibits the use of investment banking revenue to fund equity research and compensate equity analysts. We find that all-star analysts from investment banks are more likely to exit the profession or move to the buy side after the regulations. The departed star analysts’ earnings revisions and stock recommendations are more informative than those of the remaining analysts who followed the same companies. To the extent that star analysts are superior to their nonstar counterparts in terms of research ability and ability to inform the market, the exit of star …

Ecosystem-Specific Advantages In International Digital Commerce, Jiatao Li, Liang Chen, Jingtao Yi, Jiye Mao, Jianwen Liao Dec 2019

Ecosystem-Specific Advantages In International Digital Commerce, Jiatao Li, Liang Chen, Jingtao Yi, Jiye Mao, Jianwen Liao

Research Collection Lee Kong Chian School Of Business

We consider the applicability to digital platforms of extant international business scholarship. The organization of digital platforms has been seen to such an extent as predicated upon the bundling of external resources for collective value creation that their expansion may follow the logic of externalization. We further that literature contrasting the governance of network multinationals with that of platform-centric ecosystems. Building on and extending the theory of the ecosystem, we propose the concept of ecosystem-specific advantages. We identify costs and difficulties in the transfer of such advantages to new markets, emphasizing in particular the idea of bottlenecks. We then propose …

Optimal Design And Ownership Structures Of Innovative Retail Payment Systems, Zhiling Guo, Dan Ma Dec 2019

Optimal Design And Ownership Structures Of Innovative Retail Payment Systems, Zhiling Guo, Dan Ma

Research Collection School Of Computing and Information Systems

In response to the Fintech trend, an ongoing debate in the banking industry is how to design the new-generation interbank retail payment and settlement system. We propose a two-stage analytical model that takes into account the value-risk tradeoff in the new payment system design, as well as banks’ participation incentives and adoption timing decisions. We find that, as the system base value increases, banks tend to synchronize their investment and adoption decisions. When the system base value is low and banks are heterogeneous, bank association ownership maximizes social welfare. When both the system base value and bank heterogeneity are moderate, …

Quantum Consensus, Jorden Seet, Paul Griffin Dec 2019

Quantum Consensus, Jorden Seet, Paul Griffin

Research Collection School Of Computing and Information Systems

In this paper, we propose a novel consensus mechanism utilizing the quantum properties of qubits. This move from classical computing to quantum computing is shown to theoretically enhance the scalability and speed of distributed consensus as well as improve security and be a potential solution for the problem of blockchain interoperability. Using this method may circumvent the common problem known as the Blockchain Trilemma, enhancing scalability and speed without sacrificing de-centralization or byzantine fault tolerance. Consensus speed and scalability is shown by removing the need for multicast responses and exploiting quantum properties to ensure that only a single multicast is …
