Blockchain-Enabled Participatory Design In Marketing: A Collaborative Approach For Enhanced Customer Engagement, Brian Whelan Dr. Apr 2024

Blockchain-Enabled Participatory Design In Marketing: A Collaborative Approach For Enhanced Customer Engagement, Brian Whelan Dr.

Association of Marketing Theory and Practice Proceedings 2024

Participatory Design (PD) is an inclusive approach to designing products, services or systems that actively involve the people who use, will use, or be impacted by the design process (Robertson and Simonsen, 2012). PD has been applied in many domains, including architecture, urban planning, product design, healthcare administration, software development, and community engagement, but its application in marketing has been limited. The goal of this paper is to illuminate potential applications for blockchain-enabled PD initiatives in marketing, and to stimulate further thinking about how its use can lead to deeper customer engagement.


The Economic Value Of Blockchain Applications: Early Evidence From Asset-Backed Securities, Xia Chen, Qiang Cheng, Ting Luo Jan 2024

The Economic Value Of Blockchain Applications: Early Evidence From Asset-Backed Securities, Xia Chen, Qiang Cheng, Ting Luo

Research Collection School Of Accountancy

In this paper, we evaluate the economic value of a blockchain application. In the context of asset-backed securities (ABS) issuance in China, where some ABS are issued with blockchain technology and others are not, we find that the use of blockchain significantly reduces the coupon yield at issuance. Compared with other ABS, those issued using blockchain technology experience a decrease of 31.4 basis points in the yield spread, which corresponds to a relative decrease of 13%. We further document that the effect of blockchain is more pronounced for ABS deals rated by less reputable credit rating agencies and agencies that …


A Non-Contractual Approach To Smart Contracts, Florian Gamper Sep 2023

A Non-Contractual Approach To Smart Contracts, Florian Gamper

Research Collection Yong Pung How School Of Law

This article adds to the debate on what, legally speaking, smart contracts are and what they should be. Currently, much of this debate focuses on the relationship between smart contracts and legal contracts, overlooking that other legal categories may also be appropriate. This article suggests that the concept of abandonment can be fruitfully applied to smart contracts. Using the concept of abandonment has the advantage of allowing smart contracts, as close as legally possible, to be utilized as machines (or using the terminology suggested by Vitalik Buterin, founder of Etherium, as a ‘persistent script’). It would also make other issues, …

Exploring The Assetisation And Financialisation Of Non-Fungible Tokens: Opportunities And Regulatory Implications, Iris H. Y. Chiu, J.G. Allen Aug 2022

Exploring The Assetisation And Financialisation Of Non-Fungible Tokens: Opportunities And Regulatory Implications, Iris H. Y. Chiu, J.G. Allen

Research Collection Yong Pung How School Of Law

This article explores the emerging phenomenon of use cases for Non-fungible Tokens (NFTs) in novel forms of crypto-finance, a stage we call “NFT financialisation”, that can be developed from stages of consumption and commoditisation of NFTs, which are increasingly observed. Despite the emerging contests regarding property rights conferred by NFTs, the needs for commoditisation and financialisation in NFT markets would likely shape the delineation and framing of such rights in order for users to exploit the asset potential of NFTs. We argue that an institutional response is timely and beneficial for NFT financialisation. Financial regulatory governance can provide the institutions …

Decentralizing Money: Bitcoin Prices And Blockchain Security, Emiliano Sebastian Pagnotta Feb 2022

Decentralizing Money: Bitcoin Prices And Blockchain Security, Emiliano Sebastian Pagnotta

Research Collection Lee Kong Chian School Of Business

We address the determination of bitcoin prices and decentralized security. Users forecast the transactional and resale values of holdings, pricing the risk of systemic attacks. Miners contribute resources to protect against attackers and compete for block rewards. Bitcoin's design leads to multiple equilibria: the same blockchain technology is consistent with sharply different price and security levels. Bitcoin's monetary policy can lead to welfare losses and deviations from quantity theory. Price-security feedback amplifies fundamental shocks' volatility impact and leads to boom and busts unconnected to fundamentals. We characterize how viability versus fiat currency depends on bitcoin's relative acceptability and inflation protection.


Tracking Tangible Asset Ownership And Provenance With Blockchain, Mark D. Sheldon Jan 2022

Tracking Tangible Asset Ownership And Provenance With Blockchain, Mark D. Sheldon

2022 Faculty Bibliography

Blockchain transactions are recorded in a shared and append-only repository that multiple parties verify, validate, and agree-upon. While initially used to keep track of digital assets, blockchains now track the ownership and provenance of tangible assets. An inherent challenge in using blockchain for this task involves keeping the status of a tangible asset in the physical world in sync with its non-fungible token on a blockchain. While several blockchains are already being used in this manner, specific implementation details are fragmented. In response, this study examines four stages of tracking tangible assets using a consortium’s permissioned blockchain, including: design and …

Association of Marketing Theory and Practice Proceedings 2022

A revolution is brewing in the healthcare marketplace. In the early nineties, the World Wide Web initiated a new era for the use of the Internet in the consumption of healthcare services. This eventually led to the Big Data movement (Erevelles et al. 2016), which initiated a non-linear transformation in healthcare analytics and developed into a dominant paradigm in the healthcare marketplace. However, the World Wide Web architecture was never designed to support a marketplace in healthcare or, for that matter, a marketplace of any other kind. It was primarily designed for the sharing of information and was even referred …
