The Moderating Role Of Digital Multi-Sided Platform On The Firm Value Of Traditional Value-Chain Firms, Chee Pheng Lim

Dissertations and Theses Collection (Open Access)

This dissertation examines the strategic value and performance implications for traditional value-chain firms (TVCFs) that adopt digital multi-sided platforms (DMSPs) to augment their existing businesses. DMSPs facilitate interactions among multiple user groups through digital intermediaries, generating self-reinforcing network effects that enhance value creation, reduce operational and transaction costs, and enable collective innovation. Despite the prevalence of platform-based firms, 60% of global unicorns and 7 of the world’s 10 most valuable companies operate digital platforms, empirical research on the value-creation mechanisms of DMSPs remains limited. Anchored in the resource-based view and platform theory, this study investigates how DMSP moderates the relationship …

Optimizing Initial Screening For Colorectal Cancer Detection With Adherence Behavior, Sarah Yini Gao, Yan He, Ruijie Zhang, Zhichao Zheng, Shao Wei Lam Lam, Emile Tan

Research Collection Lee Kong Chian School Of Business

Background: Two-stage screening programs are widely adopted for early colorectal cancer (CRC) detection, where individuals receiving positive outcomes in the first-stage (initial) test are recommended to undergo a second-stage test (colonoscopy) for further diagnosis. Methods: We study the initial test design—the selection of cutoffs for reporting test outcomes—to balance the trade-off between screening effectiveness (i.e., CRC and polyp detection) and efficiency (i.e., colonoscopy costs), incorporating the fact that not all individuals follow up with a colonoscopy after receiving positive outcomes. We integrate the Bayesian persuasion framework with information avoidance to model this problem and apply it to Singapore's CRC screening …

Government policy is represented through two distinct incentives: a per-unit subsidy for green production and a per-use subsidy for alternative fuel vehicles, both directly reducing relevant costs in the decision space. For scalability, a tailored non-dominated sorting genetic algorithm II (NSGA-II) is developed and benchmarked against …

A Novel Robust Optimization Approach For Supply Chain Resilience: The Role Of Flexibility And Collaboration, Seyed Ashkan Hosseini Shekarabi, Reza Kiani Mavi, Neda Kiani Mavi, Flavio Romero Macau, Sobhan (Sean) Arisian

Research outputs 2022 to 2026

Supply chains are increasingly vulnerable to disruptive events that impair performance and stability. Despite research on supply chain resilience, a significant gap remains in risk management approaches on how to simultaneously minimize expected costs and control extreme cost variations. Existing methods neglect to narrow the gap between worst-case and best-case outcomes and to quantify the economic benefit of enhanced information in decision-making under uncertainty. This gap underscores the need for an integrated robust optimization framework that balances expected cost and risk while incorporating the assessment of novel digital technologies. In response, this study proposes a two-stage stochastic mixed-integer nonlinear programming …

Converting Counterfeiters In Emerging Markets To Authorized Suppliers: A New Anti-Counterfeiting Measure, Liling Lu, Xin Fang, Sarah Yini Gao, Burak Kazaz

Research Collection Lee Kong Chian School Of Business

With more products being infringed by counterfeits, anti-counterfeiting measures, such as law enforcement and consumer education, have commonly been adopted in emerging markets. In recent years, “super fakes,” i.e., counterfeits of high quality, have become popular. Super fake manufacturers’ capability to produce high-quality products inspires a new anti-counterfeiting measure: converting counterfeiters to authorized suppliers. To study the effectiveness of this anticounterfeiting measure, our paper employs a game-theoretic model to examine the interactions between a brand-name firm with its home supplier, and a counterfeiter who produces high-quality counterfeits and can be potentially converted to an authorized overseas supplier. Our results show …

Optimal Abort Policy For Mission-Critical Systems Under Imperfect Condition Monitoring, Qiuzhuang Sun, Jiawen Hu, Zhi-Sheng Ye

Research Collection College of Integrative Studies

Although most on-demand mission-critical systems are engineered to be reliable to support critical tasks, occasional failures may still occur during missions. To increase system survivability, a common practice is to abort the mission before an imminent failure. We consider optimal mission abort for a system whose deterioration follows a general three-state (normal, defective, failed) semi-Markov chain. The failure is assumed self-revealed, whereas the healthy and defective states have to be inferred from imperfect condition-monitoring data. Because of the non-Markovian process dynamics, optimal mission abort for this partially observable system is an intractable stopping problem. For a tractable solution, we introduce …

Global Commons, Local Crises: The Ecological Embeddedness Of Global Production Networks, Christopher R. Whynacht

Graduate Doctoral Dissertations

Notions of Global Production Networks (GPNs) are popular approaches to studying the complex, dispersed, and socially embedded production of goods and services. Yet, these concepts have largely struggled with incorporating environmental resources, risks, and actors. My dissertation leverages insights from Actor-Network Theory (ANT) to contextualize ecological elements of production as coequal participants with social stakeholders. I describe how GPNs are ecologically embedded and nested within the natural environment. I draw from ANT to develop a GPN framework that internalizes ecological dimensions. The second chapter in this dissertation develops these ideas and provides theoretical framing for further empirical chapters. The third …

The Aggregate Welfare And Trade Implications Of Contracting Frictions In Global Sourcing, Davin Chor, Lin Ma

Research Collection School Of Economics

How much do contracting frictions between global firms and their suppliers impact country welfare and trade? We answer this by developing a model of global sourcing under partial contractibility, where firm-supplier relationships are exposed to a bilateral holdup problem. Sourcing decisions aggregate into a gravity equation for trade flows by organizational mode (intrafirm vs. arm’s length), which we take to structural estimation. We can then evaluate welfare changes with an extended Arkolakis, Costinot and Rodriguez-Clare (2012) formula that incorporates these contracting frictions. Our counterfactual analysis reveals a sizeable average country welfare gain of 9.2% from eliminating contracting frictions in global …
